Bi-directional electrostatic discharge protection diode for portable devices

A bi-directional electrostatic discharge protection diode DF2B7ASL has been launched by Toshiba Electronics Europe. The device aims to target interface protection in applications with a minimum footprint requirement.

The DF2B7ASL is said to feature a snapback characteristic which means the device can provide low clamping voltages and low dynamic resistance of the diode to offer efficient protection to semiconductor ICs.

The device apparently has a low dynamic resistance of 0.2Ω and a low clamping voltage (VC) of 11V at 5V signal lines (VRWM ≤ 5.5V), but still offers an electrostatic discharge voltage rating of +/-30kV in accordance with IEC61000-4-2 (contact discharge).

Toshiba says its new diodes are supplied in a SOD-962 (SL2) package with a board mounting footprint of 0.32mm x 0.62mm.
