Engineering Selection Recommendations

Selection among BAT54AW equivalents can be based on product status and compliance criteria as provided. For RoHS-compliant substitution, select BAT54AW, BAT54AW-7-F, BAT54AWQ-13-F, BAT54AWQ-7-F, or BAT54AWT-TP. BAT54AW-7 does not meet RoHS compliance requirements. For designs qualified for automotive applications, BAT54AWQ-13-F and BAT54AWQ-7-F are provided with AEC-Q101 qualification as stated. Package, mounting style, and electrical parameters are matched across all listed substitutes.

Frequently Asked Questions (FAQ)

Q: Which parameters must match for a compatible diode substitution in the SC-70, SOT-323 package?
A: Diode configuration, technology (Schottky), maximum DC reverse voltage, average rectified current, forward voltage at specified current, reverse recovery time, reverse leakage current, mounting type, and package/case must match exactly for direct substitution.

Q: Are there RoHS-compliant alternatives to BAT54AW in the same package?
A: BAT54AW, BAT54AW-7-F, BAT54AWQ-13-F, BAT54AWQ-7-F, and BAT54AWT-TP are listed as ROHS3 compliant and share the SC-70, SOT-323 package.

Q: Does automotive qualification affect the suitability of these substitutes?
A: BAT54AWQ-13-F and BAT54AWQ-7-F include AEC-Q101 qualification for automotive usage as specified.

Q: Can package and mounting variations affect compatibility?
A: All listed substitutes retain the same surface mount type and SC-70, SOT-323 package, ensuring mechanical compatibility.

Q: Is reverse recovery time a determining factor for substitution?
A: All equivalents have a reverse recovery time of 5 ns, matching the specification of the BAT54AW.

Q: What compliance or regulatory factors should be considered?
A: RoHS and REACH status, as listed, may be required by application or project standards. Product status and qualification, such as automotive grade, should be selected according to project needs.
