**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SMB

TPSMBJ15A from TECH PUBLIC, in a SMB. 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 unidirectional TVS, marked by the cathode band on the SMB outline drawing; the TPSMBJ15A standoff voltage V_R is 15 V. |
| 2 | ANODE | passive | Anode terminal of the unidirectional TVS, opposite the cathode band; for TPSMBJ15A, V_BR is 16.70 V min to 18.50 V max at 1 mA and V_C is 24.4 V max at I_PP 24.6 A. |

## CAD (KiCad official)

- Symbol: `TPSMBJ15A`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `tpsmbj15a-etched.step` / `tpsmbj15a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpsmbj15a.step` / `tpsmbj15a.glb` are the bare package body.
