Device identity and surge rating
The SMCJ58CA-13 is a bidirectional Zener-type TVS diode from Diodes Incorporated, housed in a DO-214AB (SMC) surface-mount package. The 64.4 V minimum breakdown voltage ensures the avalanche region is entered cleanly before the clamp engages.
Bidirectional protection for AC or bipolar lines
No polarity orientation is needed during assembly. The operating temperature range spans -55°C to +150°C junction, covering industrial enclosures, automotive under-hood environments, and outdoor telecom cabinets. The DO-214AB SMC package provides a low-inductance path for fast transient currents, with a standard footprint shared across the SMCJ family. The 1500 W rating at the 10/1000 µs pulse is the standard TVS metric; derate for shorter or longer pulse widths per the datasheet pulse-derating curve.
