DF2S5.1FS

TOSHIBA · ESD And Surge Protection (TVS/ESD) · SOD-923

DF2S5.1FS from TOSHIBA, 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; the datasheet guarantees ±30 kV IEC61000-4-2 contact ESD protection and a working peak reverse voltage VRWM of 1.5 V max.
2 Anode passive Anode terminal of the ESD protection diode, paired with pin 1 (Cathode) as the protected line return; the device is intended for ESD protection only and not for voltage regulation.
