# DF2B7PCT

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

DF2B7PCT 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 | ESD-protected I/O line that may be used as a signal input or output, with Pin 2 connected to GND when Pin 1 is used for I/O, and the device is rated for a working peak reverse voltage VRWM of 5.5 V maximum and ESD of ±30 kV contact/air per IEC61000-4-2. |
| 2 | Pin 2 | bidirectional | Second ESD-protected terminal that must be connected to GND when Pin 1 is used for I/O, or may be used as the I/O line when Pin 1 is connected to GND. |
