# TPPESD15VL2BT

**TECH PUBLIC** · ESD Protection Devices · SOT-23

TPPESD15VL2BT from TECH PUBLIC, in a SOT-23. 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 | I/O1 | passive | Protected line 1 connected to the first bi-directional TVS diode, whose other terminal is pin 3, with 15 V maximum reverse working voltage. |
| 2 | I/O2 | passive | Protected line 2 connected to the second bi-directional TVS diode, whose other terminal is pin 3, with 15 V maximum reverse working voltage. |
| 3 | COMMON | passive | Common terminal shared by both bi-directional TVS diodes, with junction capacitance of 18 pF max measured from pin 1 to pin 3 or pin 2 to pin 3. |

## CAD (KiCad official)

- Symbol: `TPPESD15VL2BT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tppesd15vl2bt-etched.step` / `tppesd15vl2bt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tppesd15vl2bt.step` / `tppesd15vl2bt.glb` are the bare package body.
