ESDA14WY [STMicroelectronics]

ESDAxxWY series, automotive unidirectional transient voltage suppressor (TVS), has been designed for use in harsh environments to protect sensitive electronics from damage or latch-up due to electrical overstress (EOS), lightning surge and ESD without ageing effect and performance drifts.

It can therefore advantageously replace MOV (metal oxide varistor) or MLV (multi-layer varistor) as well as zener diodes, which are optimized for voltage regulation. It is the right choice for high reliability and quality systems.

In addition, this product is available in a small popular SOT323-3L (Jedec SC-70) with 2.1 mm x 2.0 mm package, ideal for space constrained applications.
