NEW TRANSIENT VOLTAGE SUPPRESSOR FAMILIES WITH 500-W, 800-W, AND 1000-W PEAK PULSE POWER RATINGS
23 April 2004 - Vishay Electronic

Two new families of transient voltage suppressors, including the first bidirectional, 800-W-rated TVS in the SMB package, were released today by Vishay Intertechnology.

The new surface-mount TRANSZORB products are offered with 500-W, 800-W, and 1000-W peak pulse power ratings (10/1000 µs waveform). Vishay offers the 500-W, unidirectional and bidrectional TVSs in the SMA package, and the 800-W bidrectional and 1000-W unidirectional TVSs in the SMB package. Vishay is the only supplier to offer these industry-leading specifications in both package types.

With a choice of maximum stand-off voltages in increments from 5 V to 40 V, the new families comprise 156 standard device options.

Designed to protect voltage-sensitive components, including MOS devices and low-power ICs, the new Vishay Semiconductors TRANSZORB devices respond instantaneously to transient overvoltage conditions in power supplies, automotive systems, the fixed telecom infrastructure, and many other applications. The devices meet IEC standards for protecting against electrostatic discharge and electrical fast transient conditions in data lines, as well as offering protection against switching transients and induced RF. A glass-passivated junction construction ensures long-term reliability.

Both the SMA and SMB packages feature an Underwriters Laboratory Flammability Classification 94V 0, built-in strain relief, and an operating temperature of −55 °C to +150 °C. Footprint dimensions are 5.10 mm by 2.66 mm by 2.13 mm high for the SMA and 5.40 mm by 3.62 mm by 2.28 mm high for the SMB.

Samples and production quantities of the new TRANSZORB transient voltage suppressors are available now, with lead times of four to six weeks for larger orders.
