The SMDJ220CA-H is a high-reliability, bidirectional TVS diode engineered for transient overvoltage protection in harsh environments. With a 3000W peak pulse power rating (10/1000µs) and AEC-Q101 qualification, it effectively suppresses bidirectional surges caused by lightning, inductive switching, and load dump events. Its DO-214AB (SMC) package ensures excellent surge endurance and stable performance in automotive, industrial control, and power supply systems.
