DESCRIPTION
Third generation Power MOSFETs from Vishay provide the
designer with the best combination of fast switching,
ruggedized device design, low on-resistance and
cost-effictiveness.
The DPAK is designed for surface mounting using vapor
phase, infrared, or wave soldering techniques. The straight
lead version (IRFU/SiHFU series) is for through-hole
mounting applications. Power dissipation levels up to 1.5 W
are possible in typical surcace mount applications.
