The SMAJ350A is a three-terminal, non-polarized surface-mount Transient Voltage Suppressor (TVS) RoHS-compliant diode manufactured by Yageo. It is constructed in the DO-214AC (SMA) package, and has a peak clamping voltage of 567V, a reverse breakdown voltage of 391V, and an off-state voltage of 350V. It is designed to protect sensitive electronic components from overvoltage caused by transients in power and signal lines.
