Over-voltage protection in 0.45×0.2mm SMT package

Offered in the industry’s smallest standard surface-mount outline of 0.45×0.2mm, the ESDAVLC6-1BV2 is one size smaller than today’s 0.6×0.3mm devices. The ESDAVLC6-1BV2 TVS diode fully satisfies the protection requirements specified in the international standard IEC 61000-4-2. Although other types of electrostatic-discharge (ESD) protectors, such as varistors, are available in the same size, these generally do not protect as effectively.

ST’s new ESDAVLC6-1BV2 has a clamping voltage half that of the nearest competing varistor in the same size package, offering greater safety for the internal components. Although useful in many applications, varistors also age, providing progressively less protection with each ESD event clamped. Bidirectional, a single part number fulfils multiple roles on pc-board. The chip has a bandwidth of 1GHz, a line capacitance of 7.5pF, and a breakdown voltage of 6V.
