93.6V Clamp 16.1A Ipp Tvs Diode Surface Mount DO-214AB (SMC)
1. SMCJ58A Substitution Conclusion
Fully substitutable. The Littelfuse SMCJ58A is identical to the original Comchip part in all key electrical parameters and physical package (58V reverse standoff voltage, 64.4V minimum breakdown voltage, 93.6V maximum clamping voltage, 1500W peak pulse power, and DO-214AB package). The only minor discrepancy is its specified peak pulse current of 16.1A compared to the original part's 16A. This 0.1A difference is considered electrically equivalent in engineering practice, likely due to variations in manufacturer testing or labeling conventions, and does not affect core transient suppression capability or design compatibility. Therefore, it can be used as a direct replacement.
2. SMCJ58A-TP Substitution Conclusion
Fully substitutable. The MCC SMCJ58A-TP matches the original part in all core technical specifications and package form, including 58V standoff voltage, 93.6V clamping voltage, 1500W peak pulse power, and SMC package. Its rated peak pulse current of 16.1A is functionally equivalent to the original 16A, with no practical performance difference. The "-TP" suffix typically denotes tape-and-reel packaging, reflecting a supply form variation rather than an electrical characteristic change. Consequently, this model can serve as a direct functional, performance, and mechanical equivalent substitute.
