Datasheet

Claimed to be the industry’s first bi-directional 1500W surface-mount PAR transient voltage suppressors (TVS) in a low-profile eSMP® SMPC (TO-277A) package, Vishay’s TPCxxCA Series is now available in Europe at TTI. The devices have a low profile of typically just 1.1mm, (around 52% lower than the traditional SMC package) and a 38% smaller footprint.

Combined with high power density, the suppressors enable designers to save board space and reduce costs.

Typical applications include protection of sensitive electronics against voltage transients induced by inductive load switching and lightning on ICs, MOSFETs, and signal lines of sensor units for automotive, consumer, computer, industrial and telecommunication equipment.

The Vishay TPC11CA to TPC36CA Surface Mount TVS feature a junction passivation optimised patented PAR construction, with a temperature range of −65degC to +185degC. Bi-directional breakdown voltage is from 11V to 36V and clamping capability is excellent at 15.6V to 49.9V.

Further benefits include low leakage current and exceptionally fast response times.

Vishay TPC11CA to TPC36CA Surface Mount TVS are ideal for automated placement and meet MSL level 1 standards per J-STD-020, as well as being RoHS-compliant and halogen-free. The devices are available in AEC-Q101-qualified versions.
