LESD5Z3.3T1G

LRC · ESD And Surge Protection (TVS/ESD) · SOD-523

LESD5Z3.3T1G from LRC, in a SOD-523. 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 K passive Cathode of the unidirectional TVS diode (marked-band side); connects to the protected signal line, with VRWM 3.3 V, IR max 1.0 uA at VRWM and VBR min 5.0 V at IT = 1.0 mA for LESD5Z3.3T1G.
2 A passive Anode of the unidirectional TVS diode; connects to ground, with VC max 14.1 V at IPP = 11.2 A and 200 W peak pulse power (8/20 us) for the series.
