SMF TVS Protection Diodes with 400W Surge

Vishay Intertechnology, Inc. today announced a new series of surface-mount transient voltage suppressor (TVS) protection diodes that are the first to feature a 2% breakdown voltage tolerance. Offered in the low-profile SMF package, Vishay Semiconductors VTVSxxASMF series devices provide high surge capability of 400W at 10/1000µs for portable electronics.

With their low 1mm profile, low-noise technology, and very fast response times, the devices released today are suited for line transient voltage protection in space-constrained electronics, such as laptops, notebooks, tablets, smartphones, and external hard drives.

The VTVSxxASMF series consists of 23 devices with working voltages from 5V to 63V, with breakdown voltage tolerances of 2% or 5% available. The TVS offer a peak pulse current from 2.9A to 20.3A, excellent clamping capability from 14.8V to 103.5V, low incremental surge resistance, and operating temperatures from -55 to +175 degrees C.

The protection diodes provide ESD capability of ± 30kV (air and contact discharge) in accordance with IEC 61000-4-2, support high-temperature soldering to 260 degrees C / 10 sec. at their terminals, and meet the MSL Level 1 standard per J-STD-020. The AEC-Q101-qualified devices are RoHS-compliant, halogen-free, and Vishay Automotive Grade. Samples and production quantities of the VTVSxxASMF series are available now, with lead times of eight weeks for larger orders.
