SI4405DY-T1-GE3-VB

VBsemi Elec · MOSFETs · SO-8

SI4405DY-T1-GE3-VB from VBsemi Elec, in a SO-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; connect with pins 2 and 3 to the source (VDS rated -30 V).
2 S passive Source of the P-channel MOSFET; connect with pins 1 and 3 to the source (VDS rated -30 V).
3 S passive Source of the P-channel MOSFET; connect with pins 1 and 2 to the source (VDS rated -30 V).
4 G input Gate of the P-channel MOSFET, rated for VGS of ±20 V maximum.
5 D passive Drain of the P-channel MOSFET, tied internally with pins 6, 7 and 8 (continuous ID -13.5 A at TC = 25 °C).
6 D passive Drain of the P-channel MOSFET, tied internally with pins 5, 7 and 8 (continuous ID -13.5 A at TC = 25 °C).
7 D passive Drain of the P-channel MOSFET, tied internally with pins 5, 6 and 8 (continuous ID -13.5 A at TC = 25 °C).
8 D passive Drain of the P-channel MOSFET, tied internally with pins 5, 6 and 7 (continuous ID -13.5 A at TC = 25 °C).
