LESD9D3.3T5G

LRC · ESD Protection Devices · SOD-923

LESD9D3.3T5G from LRC, in a SOD-923. 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 CATHODE passive Cathode terminal of the ESD protection diode, which clamps ESD transients (IEC61000-4-2 contact ±15 kV per the maximum ratings) and has a 3.3 V stand-off voltage (VRWM) for the LESD9D3.3T5G.
2 ANODE passive Anode terminal of the ESD protection diode, which clamps ESD transients (IEC61000-4-2 contact ±15 kV per the maximum ratings) and has a 3.3 V stand-off voltage (VRWM) for the LESD9D3.3T5G.
