Parameter Comparison

Engineering Selection Recommendations

The BAW101,215 from Nexperia USA Inc. is a direct parametric equivalent to the BAW101-7. Both components share identical electrical specifications across all critical performance parameters: reverse voltage rating, rectified current capacity, forward voltage characteristics, recovery time, and leakage current. Both devices are housed in mechanically compatible TO-253-4 / TO-253AA packages suitable for Surface Mount assembly.

Both parts maintain Active product status and comply with ROHS3 and REACH regulatory requirements. The BAW101,215 carries AEC-Q100 automotive qualification, which represents an additional quality assurance certification beyond the base BAW101-7 specification. This qualification does not alter electrical or mechanical compatibility but indicates the substitute part has undergone automotive-grade reliability testing.

The SOT-143B package designation for the BAW101,215 represents a variant within the SOT-143 family and maintains full mechanical and electrical compatibility with the SOT-143 package of the BAW101-7. Both parts are suitable for identical circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can the BAW101,215 be used as a direct replacement for the BAW101-7 in existing designs?

A: Yes. The BAW101,215 meets all electrical and mechanical specifications of the BAW101-7. Both components feature identical reverse voltage (300 V), rectified current (250 mA per diode), forward voltage (1.1 V @ 100 mA), recovery time (50 ns), and package footprint (TO-253-4 / TO-253AA). No circuit design changes are required.

Q: What is the difference between SOT-143 and SOT-143B packages?

A: SOT-143B is a variant designation within the SOT-143 family. Both package types maintain the same mechanical footprint, pin configuration, and electrical performance. The devices are mechanically and electrically interchangeable for PCB assembly purposes.

Q: Does the AEC-Q100 qualification on the BAW101,215 affect its use in non-automotive applications?
