MURA105T3G

onsemi · Diodes - General Purpose · SMA

MURA105T3G from onsemi, in a SMA. 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 lead, marked by the polarity band on the SMA package; the MURA105 is rated for a 50 V peak repetitive reverse voltage (VRRM) and 1.0 A average forward current at TL = 155°C.
2 ANODE passive Anode lead of the rectifier, per the SMA Style 1 pin assignment (pin 2 is the anode, opposite the polarity band).
