MDD4N65D

MDD Microdiode Semiconductor · MOSFETs · TO-252

MDD4N65D from MDD Microdiode Semiconductor, in a TO-252. 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; controls the channel, with VGS rated ±30 V and threshold VGS(TH) 2.0 to 4.0 V at VDS=VGS, ID=250μA.
2 D passive Drain (also the tab); VDS rated 650 V with continuous drain current ID of 4 A and RDS(on) max 2.8 Ω at VGS=10 V.
3 S passive Source; continuous body-diode forward current IS is 4 A and pulsed diode current is 16 A.
