# ST15100L

**Changjing** · Schottky Diodes · TO-277

ST15100L from Changjing, in a TO-277. 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 | Anode 1 | passive | Anode 1 of the Schottky rectifier, one of two anode terminals; rated 15A average forward current (IF(AV)) and 100V repetitive peak reverse voltage (VRRM). |
| 2 | Anode 2 | passive | Anode 2 of the Schottky rectifier, second anode terminal tied to the same diode as Anode 1; rated 15A average forward current (IF(AV)) and 100V VRRM. |
| 3 | Cathode | passive | Cathode, connected to the exposed heatsink tab of the TO-277 package; RθJ-L junction to terminal is 5 °C/W typical. |
