# DF2B7ASL

**TOSHIBA** · ESD And Surge Protection (TVS/ESD) · 0201

DF2B7ASL from TOSHIBA, in a 0201. 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 | Protection channel for the signal line used as I/O; the datasheet says to connect Pin 2 to GND when Pin 1 is used for I/O, with working peak reverse voltage VRWM of 5.5 V max (recommended operating condition). |
| 2 | Pin 2 | bidirectional | Protection channel for the signal line used as I/O; the datasheet says to connect Pin 1 to GND when Pin 2 is used for I/O, with working peak reverse voltage VRWM of 5.5 V max (recommended operating condition). |

## CAD (KiCad official)

- Symbol: `DF2B7ASL`
- Footprint: `Diode_SMD:D_0201_0603Metric`
- 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal _01005_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `df2b7asl-etched.step` / `df2b7asl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `df2b7asl.step` / `df2b7asl.glb` are the bare package body.
