# TPUCLAMP0501T

**TECH PUBLIC** · ESD Protection Devices · DFN1006-2

TPUCLAMP0501T from TECH PUBLIC, in a DFN1006-2. 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 | PIN1 (bar end) | passive | Terminal 1 is the end of the package marked with the black bar and labelled 'PIN1' on the marking drawing, and it is one of the two TVS diode terminals used for the 1-line unidirectional clamp (rated 5 V reverse working voltage, 6 V minimum breakdown at 1 mA). |
| 2 | PIN2 | passive | Terminal 2 is the opposite end of the package, labelled 'PIN2' on the marking drawing, and it is the other TVS diode terminal; the datasheet specifies junction capacitance of 0.35 pF typical between Pin 1 and Pin 2 at VR = 0 V, f = 1 MHz. |

## CAD (KiCad official)

- Symbol: `TPUCLAMP0501T`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `tpuclamp0501t-etched.step` / `tpuclamp0501t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpuclamp0501t.step` / `tpuclamp0501t.glb` are the bare package body.
