NSD350HT1G

onsemi · Switching Diodes · SOD-323

NSD350HT1G from onsemi, in a SOD-323. 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 CATHODE passive Cathode (polarity band) of the high voltage switching diode, rated for reverse voltage VR of 350 V and forward current IF of 200 mA DC.
2 ANODE passive Anode of the high voltage switching diode, with forward voltage VF of 1.1 V max at IF = 100 mA.
