SI4455DY

TECH PUBLIC · MOSFETs · SOIC-8

SI4455DY from TECH PUBLIC, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S passive Source of the P-channel MOSFET (pin 1 on the SOP-8 top view).
2 S passive Source of the P-channel MOSFET (pin 2 on the SOP-8 top view).
3 S passive Source of the P-channel MOSFET (pin 3 on the SOP-8 top view).
4 G input Gate of the P-channel MOSFET; VGS rated ±20 V absolute maximum, with ESD-protected gate.
5 D passive Drain of the P-channel MOSFET; VDS rated -150 V absolute maximum.
6 D passive Drain of the P-channel MOSFET; VDS rated -150 V absolute maximum.
7 D passive Drain of the P-channel MOSFET; VDS rated -150 V absolute maximum.
8 D passive Drain of the P-channel MOSFET; VDS rated -150 V absolute maximum.
