Active production, 58V rail protection
The SMBJ58CA-13 is a bidirectional TVS diode in Diodes Incorporated's SMBJ series, marked as Active in production — no end-of-life notice or NRND flag. That means it remains a standard catalog item for new designs and replacement builds alike, with no last-time-buy clock running.
Single bidirectional channel, DO-214AA package
A single bidirectional channel protects one line against both positive and negative transients — no need for two diodes in anti-series. The base product number SMBJ58 indicates the voltage family; the CA suffix confirms bidirectional polarity.
