TMMBAT46FILM 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, identified by the ring marking at the cathode end of the glass MiniMELF body; the diode has VRRM of 100 V and IF of 150 mA. |
| 2 | A | passive | Anode, the unmarked end of the MiniMELF body; the diode has VF of 0.45 V max at 10 mA and VBR of 100 V min at 100 µA. |
