MRA4005T1G

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

MRA4005T1G 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, identified by the polarity band in the plastic body; the rectifier blocks up to 600 V (VRRM/VRWM/VR for MRA4005) and conducts up to 1 A average forward current.
2 ANODE passive Anode terminal of the rectifier diode; forward current up to 1 A average (IO) and 30 A non-repetitive surge (IFSM).
