Vishay Intertechnology Inc. has released a line-up of surface-mount transient voltage suppressor (TVS) protection diodes that the company said is the industry's first to feature a two per cent breakdown voltage tolerance. The Vishay Semiconductors VTVSxxASMF series devices are available in the low-profile SMF package and claim to offer high surge capability of 400W at 10/1000?s for portable electronics.

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

VTVSxxASMF series

The VTVSxxASMF series consists of 23 devices with working voltages from 5V to 63V, with breakdown voltage tolerances of two per cent or five per cent 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 -55C to 175C.

The protection diodes provide ESD capability of 30kV (air and contact discharge) in accordance with IEC 61000-4-2, support high-temperature soldering to 260C/10s 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 with lead times of eight weeks for larger orders.
