SD05T1G

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

SD05T1G from onsemi, 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 CATHODE passive Cathode of the unidirectional ESD protection diode (marked by the polarity band), connected to the protected line; VRWM 5.0 V, VBR 6.2 to 7.3 V at 1.0 mA for SD05T1G.
2 ANODE passive Anode of the unidirectional ESD protection diode, normally connected to ground.
