Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (electrical topology must match)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mechanical and thermal interface must be identical)
• Mounting Type: Surface Mount (assembly process compatibility)
• Automotive Grade and AEC-Q101 Qualification (regulatory and reliability requirements)

Functional Performance Parameters:

• Voltage - DC Reverse (Vr) (Max): Substitute must equal or exceed 150 V
• Current - Average Rectified (Io) (per Diode): Substitute must equal or exceed 18 A
• Operating Temperature - Junction: Substitute must support -65°C ~ 150°C range
• Speed Classification: Fast Recovery characteristic required

Substitute parts are grouped based on whether they meet all mandatory criteria while maintaining or exceeding functional performance specifications. Parts that satisfy these conditions are electrically and mechanically interchangeable within the application constraints.

Engineering Selection Recommendations

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

This substitute is manufactured by the same supplier as the main part and maintains identical electrical topology and package specifications. The BYVB32-200HM3/I exceeds the voltage rating (200 V vs. 150 V) while maintaining the same current capacity (18 A) and forward voltage characteristics (1.15 V @ 20 A). Both parts utilize Standard diode technology with identical fast recovery speed classification and 25 ns reverse recovery time. Operating temperature range and automotive grade with AEC-Q101 qualification are identical. Product status is Active, ensuring long-term availability. This part is suitable for direct substitution in applications where the higher voltage rating does not create design conflicts.

STPS40170CGY-TR (STMicroelectronics)

This substitute employs Schottky diode technology rather than Standard technology, resulting in lower forward voltage (920 mV @ 20 A vs. 1.15 V @ 20 A). The STPS40170CGY-TR exceeds both voltage (170 V vs. 150 V) and current (20 A vs. 18 A) ratings. Fast recovery speed classification is maintained. Reverse leakage current is higher (30 µA @ 170 V vs. 10 µA @ 150 V). Operating temperature range extends to 175°C maximum junction temperature. Automotive grade and AEC-Q101 qualification are maintained. Product status is Active. This part is suitable for substitution in applications where Schottky technology characteristics are acceptable and the lower forward voltage drop is beneficial.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), package type (TO-263-3 D2PAK), mounting method (Surface Mount), and automotive qualification (AEC-Q101). The BYVB32-200HM3/I meets or exceeds all electrical specifications of the main part, including voltage rating, current capacity, forward voltage, and operating temperature range.

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

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. This results in lower power dissipation with the Schottky device. Both maintain the required package, configuration, and automotive qualification.

Q: Are all three parts (main and substitutes) compatible with the same PCB footprint?

A: Yes. All three parts use the TO-263-3 D2PAK package with 2 Leads + Tab configuration, ensuring identical PCB footprint and thermal interface compatibility.

Q: Does the higher voltage rating of the BYVB32-200HM3/I create any design concerns?

A: The higher voltage rating (200 V vs. 150 V) does not create design concerns for applications designed for 150 V operation. The substitute part is rated for higher voltage stress and will operate safely at or below the original design voltage.

Q: What is the impact of Schottky technology in the STPS40170CGY-TR on circuit performance?

A: Schottky diodes exhibit lower forward voltage drop (920 mV vs. 1.15 V), resulting in reduced power dissipation and heat generation. Reverse leakage current is higher (30 µA vs. 10 µA), which may be relevant in low-current or high-impedance circuit applications. Both characteristics are inherent to Schottky technology and must be evaluated within specific application requirements.

Q: Are all three parts AEC-Q101 qualified?

A: Yes. The main part BYVB32-150HE3_A/P and both substitutes (BYVB32-200HM3/I and STPS40170CGY-TR) carry AEC-Q101 qualification, meeting automotive reliability and qualification standards.

Q: What is the significance of the Last Time Buy status for the BYVB32-150HE3_A/P?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part. Existing inventory may be available, but no future production is planned. Substitution with an Active status part (BYVB32-200HM3/I or STPS40170CGY-TR) ensures long-term supply chain continuity.

Q: Can the STPS40170CGY-TR be used in all applications where the BYVB32-150HE3_A/P is currently used?

A: The STPS40170CGY-TR is electrically and mechanically compatible and meets all mandatory substitution criteria. However, the Schottky technology introduces different electrical characteristics (lower forward voltage, higher reverse leakage). Applications sensitive to these parameters must evaluate compatibility within their specific circuit design.
