# DF2B5M5CT

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

DF2B5M5CT 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 | Pin 1 | bidirectional | Used as the I/O line for ESD protection; when Pin 1 is used as I/O, Pin 2 must be connected to GND. Working peak reverse voltage VRWM is 3.3 V max. |
| 2 | Pin 2 | bidirectional | Used as the second I/O line for ESD protection; when Pin 2 is used as I/O, Pin 1 must be connected to GND. Working peak reverse voltage VRWM is 3.3 V max. |
