SMCJ70A is a unidirectional Transient Voltage Suppressor Diode designed for surge and ESD protection in portable communications, computing, and video equipment. The device features a working peak reverse voltage of 75V, breakdown voltage of 86.7V, and is housed in a compact SMC (DO-214AB) surface mount package. It delivers peak pulse power dissipation of 1500 watts with a peak forward surge current of 200 amps (8.3 ms single half sine wave), and operates reliably across a temperature range of -55°C to +150°C. The SMCJ70A offers fast response times of less than 1.0 ns and is RoHS compliant with lead-free termination, making it ideal for protecting sensitive circuits from transient voltage events in modern compact electronic designs.
