The SMAJ170A is a surface mount Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a standoff voltage of 170V and a peak pulse power dissipation of 400W. The SMAJ170A is available in the compact SMA package, making it suitable for high-density circuit board applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. This component is widely used in telecommunications, industrial control, and consumer electronics applications.
