Additional Details:
The TZMB7V5 is typically connected in parallel with the circuit being protected. The diode will remain non-conducting until the voltage exceeds its breakdown voltage. When a transient event occurs, the diode will conduct and clamp the voltage to a safe level. The datasheet specifies the peak pulse power dissipation capability of the TVS diode. It is crucial to select a TVS diode with a sufficient peak pulse power rating for the application. Detailed electrical characteristics, including breakdown voltage, clamping voltage, and leakage current, are available in the device datasheet. TVS diodes are essential components in ensuring the robustness and reliability of electronic systems. It has a fast response time to quickly clamp transient voltages.
