Package Image

Package:TO220F-7L

The STR-Y6400 series products are power ICs for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems across the full load range, by the low standby power, the quasi-resonant operation, the bottom-skip quasi-resonant operation, and the burst-oscillation.
A Compact 7 pin full mold package (TO-220F-7L, Sanken designation: FMS207).
Rich set of protection features help realize low component count, and high performance-to-cost power supply.
