TS0321LEX

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

TS0321LEX 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 passive Bidirectional TVS protected I/O line 1 (no polarity, pin 1/2 interchangeable), 3.3V working voltage, protects against ESD of ±30kV (air/contact) per IEC 61000-4-2.
2 I/O_2 passive Bidirectional TVS protected I/O line 2 (no polarity, pin 1/2 interchangeable), 3.3V working voltage, clamping voltage 15V max at IPP = 30A (8/20μs).
