SI1903DL-T1-GE3-VB

VBsemi Elec · MOSFETs · SC-70-6

SI1903DL-T1-GE3-VB from VBsemi Elec, in a SC-70-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S1 passive Source terminal of P-Channel MOSFET #1. Typically connected to the higher potential (e.g. VDD) in a high-side switch configuration.
2 G1 input Gate terminal of P-Channel MOSFET #1. Gate-source threshold VGS(th) = -0.5 V to -1.5 V; maximum VGS = ±12 V. Drive negative relative to source to turn on.
3 D2 passive Drain terminal of P-Channel MOSFET #2. VDS(max) = -20 V; continuous ID = -1.8 A at TC = 25 °C.
4 S2 passive Source terminal of P-Channel MOSFET #2. Typically connected to the higher potential (e.g. VDD) in a high-side switch configuration.
5 G2 input Gate terminal of P-Channel MOSFET #2. Gate-source threshold VGS(th) = -0.5 V to -1.5 V; maximum VGS = ±12 V. Drive negative relative to source to turn on.
6 D1 passive Drain terminal of P-Channel MOSFET #1. VDS(max) = -20 V; continuous ID = -1.8 A at TC = 25 °C.
