TVS Diode Power Rating Evaluation Using 1.5KExA series as an example
■A transient voltage suppressor (TVS) is a P-N junction of an avalanche diode designed to clamp overvoltage and dissipate high transient power surge. TVS diodes are designed to protect sensitive semiconductors from damages caused by transient voltage that comes from power source. During a voltage spike, the TVS diode junction avalanches to provide a low-impedance path for the transient current. Thus, the transient current is diverted away from the protected component and shunted through the TVS diode to the ground.
■TVS devices offer more advantages than metal-oxide varistors (MOV) since there are no ageing effects for TVS, which ensures stability over time for better reliability.
