Frequently Asked Questions (FAQ)

Q: Can RBQ10BGE10ATL be used as a direct replacement for RBQ10BM100AFHTL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package dimensions, and automotive qualifications. The difference in part number suffix reflects the supplier device package designation (TO-252 versus TO-252GE) but does not affect electrical performance or physical compatibility.

Q: Are there any differences in the TO-252 and TO-252GE package designations?

A: The package case remains TO-252-3, DPAK (2 Leads + Tab), SC-63 for both parts. The suffix designation indicates supplier-specific packaging or tape configuration but does not alter the physical dimensions or electrical characteristics relevant to circuit design.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: diode configuration (1 Pair Common Cathode), technology (Schottky), maximum reverse voltage (100 V), average rectified current (10 A per diode), forward voltage (770 mV @ 5 A), reverse leakage current (80 µA @ 100 V), and recovery speed (Fast Recovery ≤ 500 ns, > 200 mA).

Q: Are both parts suitable for automotive applications?

A: Yes. Both RBQ10BM100AFHTL and RBQ10BGE10ATL are automotive-grade components with AEC-Q101 qualification, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1), meeting automotive reliability and environmental standards.

Q: What is the maximum junction temperature for these diodes?

A: The maximum operating junction temperature for both parts is 150°C.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.
