**YFW** · Schottky Diodes · TO-263

SRT30L150DC from YFW, in a TO-263. 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 | A1 | passive | Anode of the first Schottky diode leg (PIN 1), rated 15 A per leg average forward current and 150 V reverse voltage. |
| 2 | K | passive | Common cathode of both Schottky legs (PIN 2), shown as the shortened centre lead in the TO-263 outline, with 30 A total average forward current. |
| 3 | A2 | passive | Anode of the second Schottky diode leg (PIN 3), rated 15 A per leg average forward current and 150 V reverse voltage. |
