MUR1100EG from onsemi, in a DO-41. 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 on the body; the MUR1100E is rated for a peak repetitive reverse voltage (VRRM) of 1000 V. |
| 2 | ANODE | passive | Anode; the average rectified forward current is 1.0 A at TA = 95°C (square wave, mounting method #3), with a non-repetitive peak surge current of 35 A. |
