Vishay Introduces New Bidirectional Symmetrical Single-Line ESD Protection Diode in Ultra-Compact LLP1006-2L Package

Vishay Intertechnology, Inc. announced a new bidirectional symmetrical (BiSy) single-line ESD protection diode that offers low capacitance of 14 pF in the ultra-compact LLP1006-2L package.

With a small 1.0 by 0.6mm footprint and an extremely low profile of 0.38mm, the new VCUT07B1-HD1 is designed to reduce the board space required for ESD protection in portable electronics, including notebook computers and smartphones.

At the working voltage of ±7V, the diode offers a high isolation to ground characterized by a low leakage current of <0.1µA. Any transient voltage signal exceeding the reverse breakdown voltage of 7.3V minimum at 1mA will be clamped or shorted to ground. The device features a maximum clamping voltage of 15V at 4A.

The short leads and small size of the LLP1006-2L package enable a diode with very low line inductance, allowing fast transients such as ESD strikes to be clamped with minimal over- or undershoots.

The VCUT07B1-HD1 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 4A. The device is lead (Pb)-free and complies with RoHS 2011/65/EU and Vishay "Green" environmental specifications. Soldering can be checked by standard vision inspection, with no x-ray necessary.

Samples of the VCUT07B1-HD1 will be available in Q2 2012. Production quantities will be available in Q4 2012, with lead times of eight to 10 weeks for larger orders.
