H1M from Yangzhou Yangjie Elec Tech, in a SOD-123. 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, the end marked by the cathode line on the package; H1M has VRRM 1000 V, IO 1.0 A and IFSM 30 A. |
| 2 | A | passive | Anode, the end opposite the cathode line; H1M has a maximum VF of 1.7 V at IFM=1.0A. |
