# STTH1003SBY-TR

**STMicroelectronics** · Fast Recovery / High Efficiency Diodes · DPAK

STTH1003SBY-TR from STMicroelectronics, in a DPAK. 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 | A | passive | Anode of the rectifier diode; the two A leads are connected internally, and the diode is rated 300 V VRRM and 10 A IF(AV). |
| 2 | K | passive | Cathode of the rectifier diode, which is also the metal tab; it is the center lead and is rated 300 V VRRM. |
| 3 | A | passive | Anode of the rectifier diode, internally connected to the other A lead; the diode is rated 10 A IF(AV). |
