PESD1LIN

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

PESD1LIN from UMW, 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 1 passive Protected LIN-bus line terminal; the diode to pin 2 has 15 V reverse standoff (VRWM) with breakdown 17.1 V min to 20.3 V max at IR=5 mA (pin 1 to pin 2).
2 2 passive Second terminal of the asymmetrical TVS, connected to GND in the application; the diode from pin 2 to pin 1 has 24 V reverse standoff (VRWM).
