The FSDM0565R is an integrated Pulse Width Modulator (PWM) and Sense FET specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components TO-220F-6Pins Packge.
The D81C55HC-2 is a 2k-bit static RAM (256 bytes) with parallel I/O ports and a timer. It uses silicon gate CMOS technology and consumes a standby current of 100 micro ampere, maximum, while the chip is not selected.
The MJH6287G, MJH-6287, 6287 is a 100V 20A 4MHz 160W–PNP - Darlington Bipolar Transistor Through Hole TO-218 from ON Semiconductor. MJH6284 (NPN), MJH6287 (PNP) Darlington Complementary Silicon Power Transistors.
The CD4066BM is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with the CD4016B device, but exhibits a much lower on-state resistance.
