CEA3055-VB

VBsemi Elec · MOSFETs · SOT-89

CEA3055-VB from VBsemi Elec, 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 pin; gate-source voltage is rated at ±20 V maximum, with threshold specified at VDS = VGS, ID = 250 µA.
2 D passive Drain pin, also connected to the tab; drain-source voltage is rated at 60 V with 7.0 A continuous (steady state, TA = 25 °C) and 40 A pulsed drain current.
3 S passive Source pin; connects to the body diode anode and is the return for the N-channel MOSFET current.
