CMP840

Cmos(广东场效应半导体) · IC · TO-220

CMP840 from Cmos(广东场效应半导体), in a TO-220. 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 terminal; the gate-source voltage is rated at ±30 V (VGSS), and the datasheet gives gate-body leakage limits of 100 nA forward and -100 nA reverse at VGS = ±30 V.
2 D passive Drain terminal; the device is rated at 500 V VDSS and 8 A continuous drain current at TC = 25℃ (5 A at TC = 100℃), with 32 A pulsed drain current, and the datasheet notes that drain current is limited by maximum junction temperature.
3 S passive Source terminal; the body diode is rated at a maximum continuous forward current of 8 A and a maximum pulsed forward current of 32 A.
