**TECH PUBLIC** · Schottky Diodes · SOD-123FL

TPB2A100-123FL from TECH PUBLIC, in a SOD-123FL. 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 | K | passive | Cathode, marked by the color band; the 100 V reverse voltage (VR) is blocked when this pin is positive relative to the anode. |
| 2 | A | passive | Anode; conducts forward current up to 2 A average (IF(AV) at TA=75°C), with maximum VF of 0.85 V at IF=2A. |
