Engineering Selection Recommendations

The primary selection criteria are part status, compliance certifications, and provided regulatory information. For designs requiring ROHS3 and REACH unaffected status, RFNL5BGE6STL matches all compliance and electrical parameters, and remains active. BYV25D-600,118 is RoHS compliant and active, though its REACH status is affected. STTH506B-TR offers similar electrical characteristics and superior junction temperature; however, its forward voltage at rated current (1.85 V) and junction temperature (175°C) differ from RFNL5BM6STL. For direct replacement with identical regulatory compliance and performance, RFNL5BGE6STL is fully compatible.

Frequently Asked Questions (FAQ)

Q: What are the mandatory parameters for substituting RFNL5BM6STL?
A: Mandatory parameters include DC reverse voltage (600 V), average rectified current (5 A), forward voltage at 5 A, reverse recovery time, reverse leakage current, mounting type (Surface Mount), package/case (TO-252-3, DPAK), operating junction temperature, RoHS and MSL status, and REACH status.

Q: Are mechanical and pin layout identical between substitutes?
A: All substitute parts use the TO-252-3, DPAK (2 Leads + Tab), SC-63 surface mount package, ensuring mechanical and footprint compatibility.

Q: How do reverse leakage currents compare among substitutes?
A: RFNL5BM6STL and RFNL5BGE6STL specify 10 µA @ 600 V; BYV25D-600,118 specifies 50 µA @ 600 V; and STTH506B-TR specifies 5 µA @ 600 V.

Q: What should be considered regarding product status?
A: RFNL5BM6STL is obsolete. RFNL5BGE6STL, BYV25D-600,118, and STTH506B-TR are active, making them suitable for ongoing production and design purposes.

Q: Which substitute maintains full RoHS3 and REACH unaffected status?
A: RFNL5BGE6STL is ROHS3 Compliant and REACH Unaffected, matching all specified compliance certifications. BYV25D-600,118 is RoHS Compliant but REACH Affected.

Q: Is higher junction temperature beneficial for substitution?
A: Selection must adhere to the maximum operating temperature specified for the application and original part. STTH506B-TR offers a maximum junction temperature of 175°C; other listed substitutes match the original 150°C.

Q: Does the change in forward voltage affect compatibility?
A: STTH506B-TR exhibits 1.85 V forward voltage at 5 A, while other listed substitutes specify 1.3 V at 5 A. Assessing application requirements is necessary if matching forward voltage is critical. All other electrical and mechanical characteristics conform to the allowed substitution criteria.
