93.6V Clamp 16A Ipp Tvs Diode Surface Mount DO-214AB (SMCJ)
1. SMCJ58A-E3/9AT Substitution Conclusion
The SMCJ58A-E3/9AT matches the original SMCJ58A/TR13 in all key parameters, including reverse standoff voltage (58V), breakdown voltage (64.4V), and clamping voltage (93.6V). The package is identical (DO-214AB, SMC). The peak pulse current is slightly lower at 16A compared to the original 16.1A—a marginal difference of about 0.6%. In most typical applications such as power port protection, this current deviation will not significantly affect the TVS diode’s surge suppression performance, making the substitution acceptable. For designs with extremely stringent peak current requirements—for instance, those operating near the device limits—validation in the actual circuit is recommended to ensure reliability. Overall, this is a highly compatible direct replacement.
2. MSMCJ58A Substitution Conclusion
The MSMCJ58A is electrically equivalent to the original SMCJ58A/TR13, with identical reverse standoff voltage (58V), breakdown voltage (64.4V), clamping voltage (93.6V), and package. Its peak pulse current is rated at 16A, slightly lower than the original 16.1A. This device carries military-grade certification (Grade: Military, MIL-PRF-19500), adhering to stricter standards for reliability, environmental robustness, and quality control. It is suitable for high-reliability applications such as military, aerospace, or harsh industrial environments. The current difference is negligible in practice. Substitution is feasible and can enhance system ruggedness where needed. For standard commercial applications, however, it may introduce unnecessary cost, though performance remains fully compatible.
