New series of surface-mount transient voltage suppressors fits in SlimSMA package

July 09, 2012 // By Paul Buckley
Vishay Intertechnology, Inc. has introduced a new series of surface-mount TransZorb transient voltage suppressors (TVS) in the SlimSMA DO-221AC package.

SMA6F series devices offer a very low profile of 0.95 mm, high surge capability to 600 W at 10/1000 µs and 4 kW at 8/20 µs, and excellent clamping capability.

The TVS devices are 50% thinner than devices in the traditional SMA package, yet are footprint compatible and offer 50% higher surge capability at 10/1000 µs. The SMA6F series’ low clamping voltages of 9.2 to 31.4 at 10/1000 µs and 13.4 to 36.8 at 8/20 µs are 3% to 9% lower than current TVS devices in the SMB package.

With their compact size, SMA6F TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning in space-constrained consumer, computer, industrial, and telecommunication applications. Typical end products include hard disks, hot swap computer and telecom cards, and slim LCD TVs and monitors.

The SMA6F series consists of 16 TVS devices with stand-off voltages from 5 V to 20 V. The devices offer a temperature range from - 55 to + 175 °C, provide ESD capability of 15 kV (air) and 8 kV (contact) in accordance to IEC 61000-4-2 Level 4, and meet the MSL Level 1 standard, per -STD-020, LF maximum peak of 260 °C.

Ideal for automated placement, the TVS devices are RoHS-compliant and halogen-free.


Availability

Samples and production quantities of the new SMA6F series are available now, with lead times of eight weeks for large orders.
