SMCJ54CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. This device features a working peak reverse voltage of 54 V, a breakdown voltage of 60 V, and a maximum reverse voltage rating of 69 V (RMS), with a maximum reverse current of 87.1 A. The diode is housed in a compact SMC (DO-214AB) surface mount package with lead-free, RoHS-compliant construction, offering a peak pulse power dissipation of 1500 watts and typical response times of less than 5.0 nanoseconds. It operates reliably across a temperature range of -55°C to +150°C, making it suitable for demanding applications requiring fast transient protection and high surge current handling.
