MURA220T3G 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 of the rectifier, identified by the polarity band; device is rated 200 V VRRM/VRWM/VR and 2.0 A average forward current at TL = 135C. |
| 2 | ANODE | passive | Anode lead of the rectifier; forward voltage is 0.95 V max at 2.0 A, TJ = 25C and non-repetitive peak surge current is 40 A. |
