ESD12VE

Yangzhou Yangjie Elec Tech · ESD And Surge Protection (TVS/ESD) · SOT-23

ESD12VE from Yangzhou Yangjie Elec Tech, in a SOT-23. 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 I/O1 passive ESD-protected line 1 (uni-directional TVS to GND), 12V max reverse working voltage, rated for ±30kV IEC61000-4-2 contact discharge.
2 I/O2 passive ESD-protected line 2 (uni-directional TVS to GND), 12V max reverse working voltage, rated for ±30kV IEC61000-4-2 contact discharge.
3 GND power_in Common ground/cathode-side reference for both TVS diodes; the cathode line on the package denotes the cathode end.
