Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYVB32-150HE3_A/I is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101

Allowable Parameter Ranges for Substitution:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 150 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 18 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 1.15 V @ 20 A (for standard diodes)
• Reverse Recovery Time (trr): Equal to or less than 25 ns
• Operating Temperature - Junction: Range must encompass or exceed -65°C to 150°C
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts meeting these criteria maintain electrical and thermal performance within the original design specifications while providing component availability.

Engineering Selection Recommendations

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

This part is a direct manufacturer equivalent with identical electrical performance characteristics to the BYVB32-150HE3_A/I. The BYVB32-200HM3/I maintains the same forward voltage, reverse recovery time, and current rating while providing increased reverse voltage capability (200 V versus 150 V). This part carries Active product status, ensuring long-term availability. Both parts share identical automotive qualification (AEC-Q101) and operating temperature range. The BYVB32-200HM3/I is suitable for applications where the original 150 V specification can accommodate higher voltage margins.

STPS40170CGY-TR (STMicroelectronics)

This part is a cross-manufacturer substitute utilizing Schottky diode technology rather than standard diode technology. The STPS40170CGY-TR meets all mandatory compatibility criteria: 1 Pair Common Cathode configuration, TO-263-3 D2PAK package, automotive grade, and AEC-Q101 qualification. Key electrical differences include lower forward voltage (920 mV versus 1.15 V at 20 A), higher current rating (20 A versus 18 A), and higher reverse leakage current (30 µA versus 10 µA at rated voltage). The extended operating temperature range (-40 to 175 °C) exceeds the original specification. This part is suitable for applications prioritizing reduced forward voltage drop and thermal dissipation.

Both substitute parts are in Active product status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the BYVB32-200HM3/I be used as a direct replacement for the BYVB32-150HE3_A/I?

A: Yes. The BYVB32-200HM3/I is a manufacturer-recommended equivalent. Both parts share identical diode configuration, package, current rating, forward voltage, reverse recovery time, and operating temperature range. The increased reverse voltage rating (200 V) provides additional design margin without affecting circuit performance.

Q: What is the primary difference between the BYVB32-200HM3/I and STPS40170CGY-TR?

A: The BYVB32-200HM3/I uses standard diode technology with 1.15 V forward voltage, while the STPS40170CGY-TR uses Schottky technology with 920 mV forward voltage. The Schottky variant offers lower power dissipation but exhibits higher reverse leakage current. Both meet automotive qualification and package requirements.

Q: Are all substitute parts in the same package?

A: Yes. All parts listed use the TO-263-3 D2PAK (2 Leads + Tab) TO-263AB surface mount package. Pin configuration and PCB footprint compatibility are maintained across all substitutes.

Q: Do the substitute parts maintain automotive qualification?

A: Yes. Both BYVB32-200HM3/I and STPS40170CGY-TR carry automotive-grade designation with AEC-Q101 qualification, matching the original part specification.

Q: What is the impact of using the STPS40170CGY-TR in terms of reverse leakage current?

A: The STPS40170CGY-TR exhibits 30 µA reverse leakage at 170 V compared to 10 µA for the original part at 150 V. This threefold increase in leakage current is characteristic of Schottky diode technology and must be evaluated within the specific circuit application to determine acceptability.

Q: Can the STPS40170CGY-TR be used in applications requiring the original -65°C lower temperature limit?

A: The STPS40170CGY-TR operates from -40°C to 175°C. Applications requiring operation below -40°C must use the BYVB32-200HM3/I, which maintains the original -65°C lower temperature specification.

Q: What is the current availability status of these substitute parts?

A: BYVB32-200HM3/I: 1162 pieces in stock (Active status). STPS40170CGY-TR: 2230 pieces in stock (Active status). Both parts are available for immediate procurement.
