Substitute Part Grouping Explanation

Substitution of the SS25HE3_A/I is determined by equivalence in the following critical parameters:

Voltage Rating: All substitutes maintain 50 V DC reverse voltage maximum
Current Rating: All substitutes support 2 A average rectified current
Forward Voltage Drop: All substitutes specify 700 mV maximum forward voltage at 2 A
Recovery Speed: All substitutes meet fast recovery specification ≤ 500 ns at currents > 200 mA
Package Compatibility: All substitutes use DO-214AA (SMB) surface mount package
Temperature Range: All substitutes operate across -65°C to 150°C junction temperature range
Compliance: All substitutes maintain ROHS3 compliance and EAR99 export classification

Reverse leakage current and capacitance specifications vary within acceptable ranges for this device category. The SS25HE3_A/H is an internal Vishay variant. The B250-13-F and B250Q-13 are cross-manufacturer equivalents from Diodes Incorporated with identical electrical performance and package form factor.

Engineering Selection Recommendations

SS25HE3_A/H (Vishay): Direct internal variant of the main part number. Identical electrical specifications, automotive-grade qualification, and AEC-Q101 certification. Suitable for direct substitution in all applications requiring the SS25HE3_A/I.

B250Q-13 (Diodes Incorporated): Cross-manufacturer equivalent with automotive-grade qualification and AEC-Q101 certification. Meets all electrical parameters and temperature range requirements. Appropriate for applications where automotive qualification is mandatory.

B250-13-F (Diodes Incorporated): Cross-manufacturer equivalent with identical electrical specifications and temperature range. Lacks automotive-grade designation and AEC-Q101 certification. Suitable for non-automotive applications or where automotive qualification is not required.

All substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes depends on application requirements for automotive qualification and AEC-Q101 certification.

Frequently Asked Questions (FAQ)

Q: Can the B250-13-F be used in automotive applications requiring AEC-Q101 certification?

A: No. The B250-13-F does not carry automotive-grade designation or AEC-Q101 qualification. For automotive applications, use SS25HE3_A/H or B250Q-13.

Q: Are all substitute parts pin-compatible with the SS25HE3_A/I?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint.

Q: What is the difference between SS25HE3_A/I and SS25HE3_A/H?

A: Both parts are manufactured by Vishay with identical electrical specifications, voltage ratings, current ratings, and temperature ranges. The suffix designates internal manufacturing variants. Both are fully interchangeable.

Q: Do the Diodes Incorporated B250 series parts have the same reverse leakage current as the Vishay SS25HE3 series?

A: No. The B250-13-F and B250Q-13 specify 500 µA reverse leakage at 50 V, compared to 400 µA for the SS25HE3_A/I and SS25HE3_A/H. Both values are within acceptable operating parameters for this device category.

Q: Which substitute part has the highest inventory availability?

A: The B250-13-F has 18,186 pieces in stock, compared to 4,085 pieces for SS25HE3_A/H and 3,768 pieces for B250Q-13.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the main part number and all substitutes, are ROHS3 compliant.

Q: Can I use B250-13-F in place of B250Q-13?

A: Electrically, yes. However, B250Q-13 carries automotive-grade qualification and AEC-Q101 certification while B250-13-F does not. Application requirements determine appropriateness.
