The SMAJ170A/11 is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Vishay. This device is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and other transient voltage events. It comes in a compact SMA package, making it suitable for high-density circuit board applications. The SMAJ170A/11 is a unidirectional TVS diode, meaning it provides overvoltage protection in one direction only.
