TS0421LEX

Shenzhen JingYang · ESD And Surge Protection (TVS/ESD) · SOD-323

TS0421LEX from Shenzhen JingYang, in a SOD-323. 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/O_1 bidirectional Bidirectional TVS terminal on the protected line, rated for a nominal reverse working voltage VRWM of 4.5 V and a peak pulse current of 175 A (8/20 µs).
2 I/O_2 bidirectional Bidirectional TVS terminal on the protected line, rated for ESD per IEC 61000-4-2 of ±30 kV (air) and ±30 kV (contact) as the other side of the single protected I/O line.
