Vishay Intertechnology Inc. has released a new ESD single-line protection diode in a tiny plastic SOD923 package.

With a 0.6-by-1mm footprint and a profile of 0.4mm, the VESD05A1B-02Z is designed to save board space and provide ESD protection in portable electronics for mobile computing, mobile communication, consumer, industrial, automotive and medical applications.

The new device features a low typical capacitance of 12pF at 2.5V and 19pF at 0V (ground level), and a low maximum leakage current of 0.1?A at 5V. The ESD protection diode offers breakthrough voltages of 7.5V (maximum) and 6.8V (typical) at 1mA, and a maximum clamping voltage of 11V at 3A and 9.5V at 1A.

The VESD05A1B-02Z provides transient protection for one data line as per IEC 6100042 (ESD) at 20kV (air and contact discharge) and IEC 6100045 (lightning) from 3A (tp = 8/20?s). The new device is also compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.

Samples of the new ESD single-line protection diode in the compact SOD923 package are available. Production quantities will be available this quarter, with lead times of 10 weeks for large orders.
