Parameter Comparison

Engineering Selection Recommendations

SMLJ60A-TP (Primary): Active product status with 753 units in current inventory. REACH Unaffected compliance status. Suitable for applications requiring the full operating temperature range of -55°C to 175°C.

SMDJ60A (Substitute): Active product status with 3400 units in current inventory. ROHS3 Compliant and REACH Unaffected. Operating temperature range is -55°C to 150°C, which is 25°C narrower at the upper limit compared to the primary part. Selection of this substitute is appropriate for applications where the maximum junction temperature does not exceed 150°C.

Both parts share identical electrical performance specifications and package geometry, enabling direct PCB-level substitution where thermal operating conditions are compatible.

Frequently Asked Questions (FAQ)

Q: Can SMDJ60A replace SMLJ60A-TP in all applications?

A: SMDJ60A is electrically and mechanically equivalent to SMLJ60A-TP for all specified parameters. However, the operating temperature range differs: SMDJ60A is rated to 150°C maximum junction temperature, while SMLJ60A-TP extends to 175°C. Substitution is valid only when the application's maximum junction temperature requirement does not exceed 150°C.

Q: Are the packages identical?

A: Yes. Both parts use the DO-214AB (SMC) surface-mount package. PCB footprints and reflow soldering profiles are compatible without modification.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are: 60V reverse standoff voltage, 66.7V minimum breakdown voltage, 96.8V maximum clamping voltage at peak pulse current, 31A peak pulse current rating, and 3000W peak pulse power dissipation. All substitute parts must match these values exactly.

Q: Do compliance certifications differ between the parts?

A: Both parts are REACH Unaffected. SMDJ60A carries ROHS3 Compliant certification, while SMLJ60A-TP does not list this certification in the provided data. Both are classified as EAR99 for export control purposes.

Q: What is the inventory status for each part?

A: SMLJ60A-TP has 753 units in stock. SMDJ60A has 3400 units in stock, providing greater availability for supply chain planning.
