# DF2S5M5CT

**TOSHIBA** · ESD And Surge Protection (TVS/ESD) · SOD-882

DF2S5M5CT from TOSHIBA, in a SOD-882. 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 (TVS) diode, which is rated for a working peak reverse voltage VRWM of at most 3.3 V. |
| 2 | Anode | passive | Anode terminal of the ESD protection (TVS) diode, which protects the signal line against ESD up to ±20 kV contact/air per IEC61000-4-2. |
