CPC3730CTR

IXYS · MOSFETs · SOT-89

CPC3730CTR from IXYS, in a SOT-89. 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 G input Gate of the N-channel depletion-mode FET, with gate-to-source voltage limited to ±20 V and VGS(off) of -1.6 to -3.9 V.
2 D passive Drain, rated for 350 V drain-to-source breakdown with 140 mA continuous current, also connected to the SOT-89 drain tab.
3 S passive Source of the N-channel depletion-mode FET, the reference for gate-to-source voltage.
