Alternator Diodes with an about 40% Lower V_F than Conventional [SG-K17VLEFGR, SG-K17VLEFGS]

Jun. 25, 2025

Product Category: Discretes > Diodes > Alternator Diodes

We have recently begun mass production of two alternator diodes for automotive applications — the SG-K17VLEFGR, the SG-K17VLEFGS.

Although these alternator diodes can support high currents with an average forward current of 50 A, they have 40% lower V_F than our conventional diodes (V_F = 0.67 V max.). This helps you create high-efficient alternator circuits and improve fuel efficiency.
These alternator diodes are highly reliable products that have Zener characteristics with high surge withstand capability (I_FSM = 500 A).


The SG-K17VLEFGR and the SG-K17VLEFGS have opposite polarities, and a bridge circuit can be configured efficiently in a small area by using these two types in pairs.

Supplied in a press-fit package with high heat dissipation, the products bring high reliability even under high temperature and humidity conditions. These alternator diodes are designed for use in harsh environments, such as automotive engine compartments, providing our customers with safe solutions.

The products are ideal for alternator circuits for 12 V battery.

Industry's Highest* Brightness 3528 Flat LED for In-vehicle Displays [SEP1WC1L19DTA]

May 19, 2025

Product Category: LEDs > Visible Light LEDs > Surface Mount LEDs (Flat Type)

We have recently begun mass production of the SEP1WC1L19DTA, a 3528-size (2.8 mm x 3.5 mm x 0.7 mm) flat LED with the industry's highest brightness as a white LED for automotive applications.
The SEP1WC1L19DTA has enhanced its heat dissipation with an improved package structure and has made the resin and the chip more heat-resistant, so it has achieved the industry's highest* brightness of 3500 mcd (typ.) (I_F = 30 mA), which is 1.6 times higher than our existing product.
This product is a white LED for automotive interiors that require not only high reliability but also high efficiency and high brightness.In particular, the product is ideal for backlight in black-out design, which requires high brightness.

We are also developing the SEP1xx1L series, which includes other high-brightness LEDs with a wide range of emission colors, such as blue, green, and red, in addition to this product.

* Based on our survey as of May 2025.

Black-out Design
Black-out design, with its stylish and luxurious appearance, is increasingly used in instrument panels.
In the black-out design, the instrument panel is all black and blends in with the interior when the power is off. When the power is on, the icons for the control buttons appear on the panel.
The light transmission of materials in the existing design is 40 to 50%, whereas it is as low as about 10% in black-out design, requiring LEDs with ever higher luminous intensity as the light source for the backlight.
In this design, the luminous intensity required for white LEDs is more than 4,000 mcd, which is double that of existing designs.
The SEP1WC1L19DTA achieves high luminous intensity and the high reliability required for automotive products, making it ideal for backlight sources in black-out design.

Automotive-grade Schottky Diodes with Lower Forward Voltage and Leakage Current [SPEG-21015, SPEG-21515]

Mar. 14, 2025

Product Category: Discretes > Diodes > Schottky Diodes

We have recently begun mass production of two Schottky diodes — the SPEG-21015 (150 V / 10 A) and the SPEG-21515 (150 V / 15 A).

With a trench structure, the SPEG-21015 and the SPEG-21515 achieve the forward voltage, V_F, and the reverse leakage current, I_R, which are lower than those of our existing Schottky diodes.
Their low V_F reduces conduction loss, whereas their low I_R ensures a margin for thermal runaway.
The new products enable efficient power conversion and thus minimize power loss.

These new diodes also comply with AEC-Q101 — a reliability testing standard for automotive components — and are ideal for the secondary-side rectification of automotive switching power supplies.

Compact, High-voltage, 3-phase Motor Driver Rated at 20 A with Lower Thermal Resistance and Saturation Voltage [SIM2-201]

Feb. 10, 2025

Product Category: Power Modules, IPMs > Intelligent Power Modules (IPMs)

We have newly added the SIM2-201 to the SIM2 series lineup.
Compared with our existing 20 A device (the SIM2-202B), the SIM2-201 has lower characteristics: the thermal resistance, R_(J-C)Q, and the saturation voltage, V_CE(SAT).
Our new product supports applications used in more severe thermal environments by suppressing heating temperatures.

The SIM2 series are high voltage 3-phase motor drivers that integrate transistors, pre-drive circuits, and bootstrap circuits (diodes and resistors) in a compact DIP40 package.
The DIP40 package with a direct bonding copper (DBC) structure allows the SIM2 series to be more compact but thermally enhanced.
In addition, this series has many precise functions, such as the thermal shutdown (TSD) and the temperature sensing.

These products can run on a 3-shunt current detection system, and optimally control the inverter systems of medium-capacity motors that require universal input standards.

Fully Digital-controlled Power Supply Control IC with Interleaved Totem-pole Bridgeless PFC Circuit [MD6753]

Aug. 29, 2024

Product Category: Microcontrollers (MCUs) > Digital Power Management ICs

The MD6753 is a power supply IC that combines an interleaved totem-pole control topology and a bridgeless PFC circuit to allow complex control systems to be fully digital.
With the interleaving control in critical conduction mode, the IC can achieve high-efficient yet low-noise power systems.

To support higher power applications, the MD6753 has a PFC circuit that combines a totem-pole PFC where two power MOSFETs are connected in series and the interleaved operation that uses two of the same circuits in parallel.
The MD6753 employs an interleaved control that shifts the phase of two PFC circuits by 180 degrees to make them operate the same. In this control, the input current I_IN is the sum of the currents flowing through the two inductors, L1 and L2, suppressing the input/output current ripple. This simplifies the input filter and reduces the heat generation of the output electrolytic capacitor, resulting in a smaller capacitor.
Synchronously rectifying the input voltage with Q5 and Q6 removes the diodes from the power line and improves circuit efficiency.


The MD6753 achieves these complex controls with a microcontroller chip and a high-voltage analog chip built into an SOP28 package.
These digitally controlled strategies allow application-specific optimal settings.

Applications

For devices requiring high power supplies such as:
• Audiovisual Equipment
• Office Automation Equipment (e.g., Server, Multifunction Printer)
• Industrial Equipment
• Communication Equipment
