**TECH PUBLIC** · Schottky Diodes · SOD-323

TPB02A40-323 from TECH PUBLIC, in a SOD-323. 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 | CATHODE | passive | Cathode terminal of the Schottky diode, labelled pin 1 in the schematic; the device DC reverse voltage is 40 V and mean rectifying current is 200 mA per the absolute maximum ratings. |
| 2 | ANODE | passive | Anode terminal of the Schottky diode, labelled pin 2 in the schematic; forward voltage is 0.39 V max at IF=10 mA and 0.55 V max at IF=200 mA. |
