The STMicroelectronics Automotive unidirectional transient voltage suppressor has been designed for use in harsh environments to protect sensitive electronics from damage or latch up due to electrical overstress, 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.
AEC-Q101 qualified and PPAP capable
Dual line unidirectional ESD and EOS protection
High ESD protection level up to 30 kV
Fast turn-on and low clamping voltage
Operating Tj max 175 °C
SOT 323-3L package
ECOPACK2 RoHS compliant component
