STMicroelectronics · Schottky Diodes · DPAK
STPS340B-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 | NC | unconnected | No connection; the left lead of the DPAK is labelled NC on the package picture. |
| 2 | K | passive | Cathode, connected to the thermal tab (the centre lead is trimmed); the tab is the DPAK thermal pad with Rth(j-c) max 5.5 °C/W and VRRM 40 V. |
| 3 | A | passive | Anode; the diode conducts IF(AV) 3 A (TC = 135 °C, δ = 0.5) with VF typ. 0.52 V at 3 A, Tj = 125 °C. |
