The ESD12VD3B is designed for automotive and industrial electronics requiring enhanced reliability under harsh transient conditions. Operating at a 12V reverse working voltage with breakdown between 13.5–15.5V, it clamps surge voltages to approximately 17V at 5A and 24V at 15A under 8/20μs waveform. With peak pulse power of 350W, ±30kV IEC ESD immunity, and ultra-fast response below 1ns, it is ideally suited for vehicle control units, industrial automation systems, computing equipment, and rugged interface protection.
