Vishay Intertechnology Inc. announces its latest product for its CLP0603 silicon packagethe bidirectional symmetrical (BiSy) protection diode or VCUT05D1-SD0, which gives protection from transient voltage signals found in portable electronics.

Featuring a tiny 0.60.3mm footprint with a very low package height of less than 0.3 mm, the VCUT05D1-SD0 requires just a third of the space required by devices in the 1006 (mm) or 0603 (in.) footprint packages for active ESD protection in portable gaming systems, digital cameras, MP3 players, mobile phones, smartphones, and other portable systems.

At a working voltage of 5.5V, the diode offers high isolation to ground characterized by a low leakage current of less than 0.1?A. Any transient voltage signal exceeding the reverse breakdown voltage of 8V typical at 1mA will be clamped or shorted to ground. The device features a maximum clamping voltage of 10V at 1A.

The small and leadless CLP0603 package enables a diode with very low line inductance, allowing fast transients such as ESD strikes to be clamped with minimal over- or undershoots.

The VCUT05D1-SD0 provides transient protection for one data line as per IEC 61000-4-2 at 30kV (air and contact discharge), and high surge current protection according to IEC 61000-4-5 at 6A. The device is lead-free and complies with RoHS 2002/95/EC and WEEE 2002/96/EC.

Samples of the VCUT05D1-SD0 will be available in 3Q11. Production quantities will be available in 1Q12 with a lead time of 8 to 10 weeks for large orders.
