MURA120T3G

onsemi · Diodes - General Purpose · SMA(DO-214AC)

MURA120T3G from onsemi, in a SMA(DO-214AC). 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, identified by the polarity band on the package; for MURA120T3G the maximum repetitive reverse voltage (VRRM) is 200 V.
2 ANODE passive Anode lead, on the side opposite the polarity band; average forward current is rated 1.0 A at TL = 155°C and 2.0 A at TL = 135°C for this device family.
