SMCJ48CA is a bidirectional 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 48 V, a breakdown voltage of 53.3 V, and a maximum reverse leakage current of 5 µA at the rated voltage. It is housed in a compact SMC (DO-214AB) surface mount package with lead-free, RoHS-compliant construction and delivers 1500 watts peak pulse power dissipation with a typical response time of less than 5.0 ns. The SMCJ48CA is ideal for protecting sensitive circuits from transient overvoltage events, offering reliable performance across an operating temperature range of -55°C to +150°C.
