Parameter Comparison

Engineering Selection Recommendations

Both the SMLJ60CA-TP and SMDJ60CA are active production components with equivalent electrical and mechanical specifications for general-purpose TVS diode applications. Selection between these parts should be based on the following factors:

SMLJ60CA-TP (Micro Commercial Co): Supports extended operating temperature range to 175°C junction temperature. Select this part for applications requiring maximum thermal headroom or operation in elevated ambient conditions.

SMDJ60CA (Alpha & Omega Semiconductor): Operates to 150°C junction temperature and carries ROHS3 compliance certification. Select this part for applications with standard thermal requirements and where RoHS3 compliance documentation is required. Current inventory availability is 2073 units.

Both components are REACH Unaffected and classified under ECCN EAR99 with identical HTSUS code 8541.10.0080. Pin-to-pin and footprint compatibility is confirmed for direct PCB substitution in DO-214AB (SMC) package applications.

Frequently Asked Questions (FAQ)

Q: Can SMDJ60CA directly replace SMLJ60CA-TP on existing PCBs?

A: Yes. Both components use identical DO-214AB (SMC) surface-mount packages with matching pin configurations and footprints. Direct substitution is mechanically and electrically compatible for general-purpose interface protection circuits.

Q: What is the difference in operating temperature range between these parts?

A: The SMLJ60CA-TP operates from -55°C to 175°C junction temperature, while the SMDJ60CA operates from -55°C to 150°C. For applications operating near or above 150°C junction temperature, the SMLJ60CA-TP provides extended thermal margin.

Q: Are the electrical specifications identical?

A: Yes. Both parts share identical voltage ratings (60V standoff, 66.7V breakdown minimum, 96.8V clamping maximum), peak pulse current (31A), and power dissipation (3000W). They are electrically equivalent for all specified parameters.

Q: What compliance certifications apply to each part?

A: Both parts are REACH Unaffected. The SMDJ60CA carries additional RoHS3 compliance certification. Both are classified as EAR99 for export control purposes.

Q: Which part should be selected for new designs?

A: Selection depends on application thermal requirements and compliance documentation needs. For standard operating conditions with RoHS3 compliance requirements, SMDJ60CA is suitable. For extended temperature operation or designs requiring 175°C thermal capability, SMLJ60CA-TP is appropriate.
