SMCJ58CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment applications. This device features a working peak reverse voltage of 58 V, a breakdown voltage of 64.4 V, and a maximum reverse voltage rating of 74.6 Vrms, with a compact SMC (DO-214AB) surface mount package. The diode delivers peak pulse power dissipation of 1500 watts at a 1 ms pulse width and maintains steady-state power dissipation of 5.0 watts at 75°C, with typical response times under 5.0 nanoseconds for bidirectional operation. Lead-free and RoHS compliant, the SMCJ58CA operates reliably across a temperature range of -55°C to +150°C, making it ideal for protecting sensitive circuits from transient voltage events in compact electronic designs.
