MURS240T3G

onsemi · Diodes - Fast Recovery Rectifiers · SMB

MURS240T3G from onsemi, in a SMB. 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 K passive Cathode lead, identified by the polarity band on the SMB (Case 403A) package; device blocks up to 400 V (VRRM/VRWM/VR) for MURS240T3G.
2 A passive Anode lead at the end opposite the polarity band; average forward current 2.0 A at TL = 125°C, 35 A non-repetitive surge.
