Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYVB32-100HE3_A/I is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Voltage - DC Reverse (Vr) (Max): 100 V or higher
• Current - Average Rectified (Io) (per Diode): 18 A or higher
• Operating Temperature - Junction: -65°C ~ 150°C or wider range
• Mounting Type: Surface Mount

Compliance Parameters:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute parts must meet or exceed the voltage and current ratings of the original part while maintaining identical package geometry and electrical configuration. Parts with lower current ratings or voltage ratings are not suitable replacements. Technology variations (Standard, Super Barrier, Schottky) are acceptable provided all mandatory parameters are satisfied.

Engineering Selection Recommendations

BYVB32-200HM3/I (Vishay General Semiconductor - Diodes Division)

This part is the manufacturer-recommended equivalent from Vishay. It maintains identical current rating (18 A), forward voltage characteristics (1.15 V @ 20 A), and reverse recovery time (25 ns). The voltage rating is increased to 200 V, providing enhanced margin for overvoltage conditions. Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance. Product status is Active, ensuring long-term availability. This substitute is suitable for applications where the original 100 V rating is adequate and higher voltage margin is beneficial.

SBR30A100CTB-13-G (Diodes Incorporated)

This part provides equivalent voltage rating (100 V) and maintains the same package geometry (TO-263-3, D2PAK). Current rating is reduced to 15 A, which is below the original 18 A specification. Forward voltage is lower (850 mV @ 15 A) due to Super Barrier technology. The part carries AEC-Q101 automotive qualification and ROHS3 compliance with Active product status. This substitute is suitable only for applications where the 15 A current rating is sufficient.

SBR30A100CTB-13 (Diodes Incorporated)

This part is functionally equivalent to SBR30A100CTB-13-G with identical electrical specifications (100 V, 15 A, 850 mV @ 15 A). Automotive grade designation is not specified in the provided data. Product status is Active with ROHS3 compliance. Current rating of 15 A is below the original specification. This substitute is suitable only for applications where the 15 A current rating is sufficient.

STPS20H100CGY-TR (STMicroelectronics)

This part provides equivalent voltage rating (100 V) in the same package (TO-263-3, D2PAK). Current rating is reduced to 10 A, which is significantly below the original 18 A specification. Schottky technology provides lower forward voltage (770 mV @ 10 A). Operating temperature range extends to 175°C. The part carries AEC-Q101 automotive qualification and ROHS3 compliance with Active product status. This substitute is suitable only for applications where the 10 A current rating is sufficient.

Frequently Asked Questions (FAQ)

Q: Can the BYVB32-200HM3/I be used as a direct replacement for the BYVB32-100HE3_A/I?

A: Yes. The BYVB32-200HM3/I is the manufacturer-recommended equivalent. It maintains identical current rating (18 A), forward voltage (1.15 V @ 20 A), and reverse recovery time (25 ns). The increased voltage rating (200 V vs. 100 V) provides additional design margin without affecting circuit operation in 100 V applications.

Q: Why do the Diodes Incorporated SBR30 parts have lower current ratings?

A: The SBR30A100CTB-13 and SBR30A100CTB-13-G are rated for 15 A average rectified current per diode, compared to 18 A for the original part. These parts use Super Barrier technology, which provides lower forward voltage but different thermal and current handling characteristics. Selection of these parts requires verification that the application current does not exceed 15 A.

Q: What is the difference between SBR30A100CTB-13 and SBR30A100CTB-13-G?

A: Both parts have identical electrical specifications (100 V, 15 A, 850 mV @ 15 A). The primary difference is that SBR30A100CTB-13-G explicitly specifies Automotive grade and AEC-Q101 qualification, while SBR30A100CTB-13 does not include these designations in the provided data. For automotive applications, SBR30A100CTB-13-G is the appropriate selection.

Q: Can the STPS20H100CGY-TR be used in place of the BYVB32-100HE3_A/I?

A: The STPS20H100CGY-TR is not a suitable direct replacement. While it maintains the 100 V voltage rating and TO-263-3 D2PAK package, the current rating is reduced to 10 A, which is significantly below the original 18 A specification. This part is suitable only for applications where the maximum current requirement does not exceed 10 A.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (BYVB32-200HM3/I, SBR30A100CTB-13, SBR30A100CTB-13-G, and STPS20H100CGY-TR) are ROHS3 compliant.

Q: Do all substitute parts have AEC-Q101 automotive qualification?

A: BYVB32-200HM3/I, SBR30A100CTB-13-G, and STPS20H100CGY-TR explicitly carry AEC-Q101 qualification. SBR30A100CTB-13 does not include this designation in the provided data. For automotive applications requiring AEC-Q101 qualification, select from BYVB32-200HM3/I, SBR30A100CTB-13-G, or STPS20H100CGY-TR.

Q: What is the key difference between Standard, Super Barrier, and Schottky diode technologies in these parts?

A: The original BYVB32-100HE3_A/I uses Standard technology. The SBR30 parts use Super Barrier technology, which provides lower forward voltage (850 mV vs. 1.15 V) but with reduced current rating (15 A vs. 18 A). The STPS20H100CGY-TR uses Schottky technology, providing the lowest forward voltage (770 mV) but with the lowest current rating (10 A). Technology selection depends on application requirements for forward voltage drop and current handling.

Q: Is the TO-263-3 D2PAK package identical across all substitute parts?

A: Yes. All substitute parts use the TO-263-3 D2PAK package (2 Leads + Tab), ensuring identical PCB footprint and thermal interface characteristics. Physical compatibility is maintained across all listed substitutes.
