TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · 0402

TPESD0402G24V from TECH PUBLIC, in a 0402. 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	Bidirectional ESD suppressor terminal; no polarity, either terminal connects to the protected signal line and the other to GND, with 24V max continuous operating voltage (VDC).
2	2	passive	Bidirectional ESD suppressor terminal; no polarity, either terminal connects to the protected signal line and the other to GND, with 24V max continuous operating voltage (VDC).

Symbol: TPESD0402G24V
Footprint: Diode_SMD:D_0402_1005Metric
3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal 0402 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: tpesd0402g24v-etched.step / tpesd0402g24v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesd0402g24v.step / tpesd0402g24v.glb are the bare package body.
