MMSD4148T3G

onsemi · Switching Diodes · SOD-123

MMSD4148T3G from onsemi, in a SOD-123. 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 terminal of the switching diode, rated for a continuous reverse voltage VR of 100 V and a forward current IF of 200 mA.
2 ANODE passive Anode terminal of the switching diode, which carries the forward current with a repetitive peak forward current IFRM of 0.5 A and a forward surge current IFSM of 1.0 A (t = 1 s) or 2.0 A (t < 1 s).
