TMMBAT42FILM from STMicroelectronics, in a MiniMELF. 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 | K | passive | Cathode, marked by the ring at the cathode end of the MINIMELF body; the 30 V repetitive peak reverse voltage is applied positive on this terminal relative to the anode. |
| 2 | A | passive | Anode, the terminal opposite the cathode ring; maximum continuous forward current is 200 mA. |
