# TPVESD05A1B-HD1

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · DFN1006-2

TPVESD05A1B-HD1 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 | Terminal 1 of the uni-directional TVS diode, shown as the top terminal of the pin configuration, which the device rates for a working peak reverse voltage (VRWM) of 5.0 V max and a clamping voltage of 12.3 V max at maximum IPP. |
| 2 | 2 | passive | Terminal 2 of the uni-directional TVS diode, shown as the bottom terminal of the pin configuration, forming the other end of the same 5 V-rated TVS path (breakdown 6.2 V min at IT = 1.0 mA). |
