# RCLAMP0531T

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

RCLAMP0531T 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 | 1 | passive | One terminal of the bidirectional TVS diode, marked by the chamfered corner in the diagram; the datasheet gives reverse working voltage VRWM 5 V max, breakdown VBR 6.5 V min, and junction capacitance 0.3 pF typ. |
| 2 | 2 | passive | The other terminal of the bidirectional TVS diode, with the same limits as pin 1 (VRWM 5 V max, VBR 6.5 V to 9.0 V, CJ 0.3 pF typ at VR = 0 V, f = 1 MHz). |

## CAD (KiCad official)

- Symbol: `RCLAMP0531T`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `rclamp0531t-etched.step` / `rclamp0531t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rclamp0531t.step` / `rclamp0531t.glb` are the bare package body.
