It is rated for 600W peak pulse power per the 10/1000 µs waveform, with a reverse standoff voltage of 58V and a maximum clamping voltage of 93.6V at 6.4A peak pulse current.
This makes the part suitable for outdoor telecom, industrial power supplies, and automotive-adjacent environments where the board may see wide thermal swings.
Within the same SMBJ family, the unidirectional variant SMBJ58A (or SMBJ58AE3/TR13) shares the same DO-214AA footprint and 58V standoff, but protects only one polarity. For a bidirectional replacement, any SMBJ58CA from other reputable manufacturers (e.g., Littelfuse, Vishay) with the same DO-214AA package and 58V standoff is electrically interchangeable — confirm the clamping voltage and peak pulse power match the 93.6V and 600W ratings before substituting.
