The SMAJ170A is a low-capacitance, bidirectional transient voltage suppressor (TVS) diode from STMicroelectronics. This TVS diode features an ultra-low clamping voltage, ultra-low reverse leakage, and high surge capability. It is designed to protect sensitive devices from voltage transients induced by lightning, inductive load switching, electrostatic discharge (ESD), or other sources. The SMAJ170A is specifically designed for automotive applications and is qualified according to the AEC-Q101 standard.
