Substitute Part Grouping Explanation

Substitute parts for the VB20150C-E3/4W are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is governed by the following parameters:

Electrical Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (pinout compatibility)
• Technology: Schottky (fast recovery characteristics)
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 150 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 10 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB

Compliance Criteria:

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The STPS16170CG-TR meets all electrical and mechanical requirements with enhanced voltage rating (170 V vs. 150 V) and maintains identical package configuration and compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The STPS16170CG-TR from STMicroelectronics is a qualified substitute for the VB20150C-E3/4W based on the following engineering criteria:

Package and Pinout Compatibility: Both components utilize the identical TO-263-3 D2PAK surface mount package with 2 leads plus tab configuration, ensuring direct mechanical and electrical compatibility without PCB redesign.

Electrical Substitution Basis: The STPS16170CG-TR maintains the required 1 Pair Common Cathode Schottky diode configuration with fast recovery characteristics (≤ 500ns, > 200mA). The substitute part exceeds the minimum voltage requirement with a 170 V rating compared to the 150 V specification of the original part, providing additional design margin in reverse voltage applications.

Compliance and Certification: Both components are Active products with full RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent regulatory and environmental compliance.

Current Rating Consideration: The STPS16170CG-TR is rated for 8 A average rectified current per diode, which is lower than the VB20150C-E3/4W rating of 10 A. This substitute is suitable for applications requiring 8 A or less per diode. Applications requiring the full 10 A rating per diode must retain the original VB20150C-E3/4W specification.

Thermal Performance: The substitute part offers an extended maximum junction temperature of 175°C compared to 150°C for the original part, providing improved thermal margin in high-temperature operating environments.

Frequently Asked Questions (FAQ)

Q: Can the STPS16170CG-TR be used as a direct replacement for the VB20150C-E3/4W in all applications?

A: The STPS16170CG-TR is a direct mechanical and pinout replacement. However, the substitute part is rated for 8 A average rectified current per diode versus 10 A for the original part. Applications operating at or above 8 A per diode must verify that the substitute part's current rating is sufficient for the specific circuit requirements.

Q: Are there any PCB layout modifications required when substituting the STPS16170CG-TR for the VB20150C-E3/4W?

A: No PCB layout modifications are required. Both components use the identical TO-263-3 D2PAK surface mount package with the same lead configuration and thermal tab placement.

Q: What is the difference in forward voltage drop between these two parts?

A: The VB20150C-E3/4W specifies a maximum forward voltage of 1.2 V at 10 A, while the STPS16170CG-TR specifies 920 mV at 8 A. These measurements are taken at different current levels, making direct comparison impractical. Circuit designers must evaluate forward voltage characteristics at the actual operating current of their application.

Q: Does the STPS16170CG-TR provide better reverse leakage performance?

A: Yes. The STPS16170CG-TR exhibits 15 µA reverse leakage at 170 V, compared to 150 µA at 150 V for the VB20150C-E3/4W. The substitute part demonstrates significantly lower reverse leakage current.

Q: Are both parts available in the same packaging format?

A: Yes. Both the VB20150C-E3/4W and STPS16170CG-TR are supplied in TO-263-3 D2PAK surface mount packages. The VB20150C-E3/4W is available in Tube packaging, while the STPS16170CG-TR is available in Tape & Reel (TR) format. Both packaging formats are standard for surface mount component handling and assembly.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited) for moisture sensitivity. Both parts carry the same regulatory and environmental compliance status.

Q: Can the STPS16170CG-TR handle higher temperatures than the VB20150C-E3/4W?

A: Yes. The STPS16170CG-TR is rated for a maximum junction temperature of 175°C, compared to 150°C for the VB20150C-E3/4W. The substitute part provides 25°C additional thermal headroom for high-temperature applications.
