Engineering Selection Recommendations

Direct Equivalent (Preferred):

BYVB32-200HM3/I is the manufacturer-recommended equivalent from Vishay General Semiconductor - Diodes Division. This part maintains identical diode configuration, package format, and mounting type. It provides enhanced voltage rating (200 V vs. 100 V) while preserving the same current capacity (18 A) and forward voltage characteristics. Both parts carry automotive-grade qualification and AEC-Q101 certification. The BYVB32-200HM3/I is in Active product status with higher inventory availability (1162 pcs vs. 1042 pcs).

Alternative Substitutes (Current-Limited Applications):

SBR30A100CTB-13 and SBR30A100CTB-13-G are manufacturer-recommended alternatives from Diodes Incorporated. Both employ Super Barrier technology and maintain the same voltage rating (100 V) and package format. However, these parts are rated for 15 A average rectified current per diode, representing a 17% reduction from the 18 A specification of the main part. These alternatives are suitable for applications where the circuit design accommodates the reduced current rating. SBR30A100CTB-13-G includes automotive-grade qualification and AEC-Q101 certification. Both parts demonstrate superior reverse leakage characteristics (4.5 µA vs. 10 µA) and lower forward voltage drop (850 mV vs. 1.15 V).

Limited-Current Alternative (Specialized Applications):

STPS20H100CGY-TR is a manufacturer-recommended alternative from STMicroelectronics employing Schottky technology. This part is rated for 10 A average rectified current per diode, representing a 44% reduction from the main part specification. The Schottky technology provides the lowest forward voltage drop (770 mV @ 10 A) and superior reverse leakage performance (4.5 µA @ 100 V). This part carries automotive-grade qualification and AEC-Q101 certification. The extended operating temperature range (-40°C to 175°C) provides additional thermal margin. STPS20H100CGY-TR is suitable only for applications where circuit design accommodates the significantly reduced current rating.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance and automotive-grade qualification. Parts designated with AEC-Q101 certification (BYVB32-200HM3/I, SBR30A100CTB-13-G, STPS20H100CGY-TR) are qualified for automotive applications. Selection should prioritize parts matching the original application's automotive requirements and environmental specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. BYVB32-200HM3/I is the manufacturer-recommended equivalent. Both parts share identical diode configuration (1 Pair Common Cathode), package format (TO-263-3, D2PAK), mounting type (Surface Mount), current rating (18 A), and forward voltage characteristics (1.15 V @ 20 A). The higher voltage rating (200 V vs. 100 V) provides enhanced design margin without affecting circuit compatibility. Both parts carry automotive-grade qualification and AEC-Q101 certification.

Q: What is the primary limitation of SBR30A100CTB-13 and SBR30A100CTB-13-G as substitutes?

A: The current rating is reduced to 15 A per diode, compared to 18 A for the main part. This represents a 17% reduction in current capacity. These parts are suitable only for applications where the circuit design accommodates this lower current specification. Both parts maintain the same voltage rating (100 V) and package format (TO-263-3, D2PAK).

Q: Why does STPS20H100CGY-TR have a lower current rating than other substitutes?

A: STPS20H100CGY-TR employs Schottky diode technology, which differs fundamentally from the Standard and Super Barrier technologies used in other alternatives. Schottky diodes inherently have lower current-handling capacity but provide superior forward voltage characteristics (770 mV vs. 1.15 V) and faster switching performance. This part is suitable only for applications where the 10 A per diode rating meets circuit requirements.

Q: Are all substitute parts automotive-qualified?

A: BYVB32-200HM3/I, SBR30A100CTB-13-G, and STPS20H100CGY-TR carry automotive-grade qualification and AEC-Q101 certification. SBR30A100CTB-13 does not list automotive-grade designation or AEC-Q101 qualification in the provided specifications. For automotive applications, select parts explicitly designated with automotive-grade and AEC-Q101 certification.

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

A: Both parts are manufactured by Diodes Incorporated and employ Super Barrier technology with identical electrical specifications (100 V, 15 A, 850 mV forward voltage). The primary difference is that SBR30A100CTB-13-G includes automotive-grade qualification and AEC-Q101 certification, while SBR30A100CTB-13 does not. For automotive applications, SBR30A100CTB-13-G is the appropriate selection.

Q: Can substitute parts with lower current ratings be used in the original circuit design?

A: Substitution with lower current-rated parts (SBR30A100CTB-13, SBR30A100CTB-13-G at 15 A, or STPS20H100CGY-TR at 10 A) requires circuit design verification. The application must confirm that the reduced current rating does not exceed the thermal and electrical stress limits of the substitute part. Thermal analysis and current distribution verification are necessary before implementation.

Q: What packaging considerations apply to these substitute parts?

A: All substitute parts maintain the same Surface Mount TO-263-3 (D2PAK) package format with 2 Leads + Tab configuration. This ensures mechanical and thermal compatibility with the original circuit board layout and assembly process. No PCB redesign or reflow profile modification is required for package compatibility.

Q: How does the reverse recovery time specification affect substitution?

A: The main part BYVB32-100HE3_A/P specifies a reverse recovery time (trr) of 25 ns. BYVB32-200HM3/I maintains this specification. SBR30A100CTB-13 and SBR30A100CTB-13-G do not provide trr specifications in the available data. STPS20H100CGY-TR does not provide trr specifications. For applications sensitive to switching transients or high-frequency operation, the specified 25 ns recovery time of BYVB32-200HM3/I provides documented performance assurance.
