The SMDJ9.0A-H is an automotive-grade, high-reliability TVS diode designed for transient overvoltage protection on 9.0V DC power lines. Rated at 3000W peak pulse power (10/1000µs) and compliant with AEC-Q101, it provides fast clamping response against ESD, inductive switching, and load transients. The DO-214AB (SMC) package ensures robust thermal performance and long-term reliability in automotive and industrial electronics.
