The SMAJ5.0CA with ESD Suppressors TVS Diodes SMAJ DO-214AC 5V 9.2V is a two-terminal surge-protection device (SPD) manufactured by Yageo for use in high-end applications. It is specifically designed to protect sensitive electronic equipment from electrostatic discharges (ESD) and reinforce the circuit protection. The device is made up of two halves: a positive silicon diode (P-SMAJ DO-214AC) and a negative silicon diode (S-SMAJ DO-214AC) in SMAJ (Surface Mounted Avalanche Junction) technology. The 5V standoff voltage indicates the voltage rating at which the device can start to conduct current to protect a circuit. The 9.2V maximum breakdown voltage of this component specifies the maximum voltage at which it can remain in its conducting state without sustaining damage.
