Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VB10170C-E3/8W are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 170 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 5 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or lower than 1.03 V
• Current - Reverse Leakage @ Vr: Equal to or lower than 90 µA @ 170 V
• Operating Temperature - Junction: Maximum equal to or greater than 175°C

The STPS16170CG-TR qualifies as a substitute part because it maintains identical diode configuration, Schottky technology, 170 V reverse voltage rating, D2PAK package, and fast recovery speed characteristics while providing enhanced current capacity and improved electrical performance within allowable parameters.

Engineering Selection Recommendations

VB10170C-E3/8W Selection Criteria:

• Primary choice when Vishay component qualification is required
• Specified in designs with 5 A per diode current requirements
• Preferred when forward voltage specification of 1.03 V @ 5 A is design-critical
• Active product status with established supply chain

STPS16170CG-TR Selection Criteria:

• Direct substitute when higher current capacity (8 A per diode) is required or beneficial
• Preferred when lower forward voltage (920 mV @ 8 A) reduces thermal dissipation
• Advantageous when lower reverse leakage current (15 µA @ 170 V) improves circuit performance
• STMicroelectronics qualification required in design specifications
• Active product status with established supply chain

Both parts maintain ROHS3 compliance, MSL 1 rating, and identical package/mounting characteristics. Selection between these parts is determined by current capacity requirements, thermal performance objectives, and manufacturer qualification specifications.

Frequently Asked Questions (FAQ)

Q: Can STPS16170CG-TR directly replace VB10170C-E3/8W in existing designs?

A: Yes, within the constraints of electrical and mechanical parameters. Both components share identical diode configuration (1 pair common cathode), Schottky technology, 170 V reverse voltage rating, TO-263-3 D2PAK package, and fast recovery speed characteristics. The STPS16170CG-TR provides higher current capacity (8 A vs. 5 A) and lower forward voltage, making it electrically compatible for applications designed for the VB10170C-E3/8W.

Q: What are the key electrical differences between these parts?

A: The STPS16170CG-TR provides three electrical advantages: (1) higher average rectified current rating of 8 A per diode compared to 5 A, (2) lower forward voltage of 920 mV @ 8 A compared to 1.03 V @ 5 A, and (3) lower reverse leakage current of 15 µA @ 170 V compared to 90 µA @ 170 V. All other electrical parameters, including reverse voltage rating and operating temperature range, remain equivalent.

Q: Are the packages identical?

A: Yes. Both the VB10170C-E3/8W and STPS16170CG-TR use the TO-263-3 D2PAK (2 Leads + Tab) surface mount package with TO-263AB supplier device package designation. Pin configuration and PCB footprint are identical, enabling direct board-level substitution.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity level rating, and are REACH unaffected. Both maintain EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Q: Which part should be selected for new designs?

A: Selection depends on application current requirements and thermal performance objectives. For applications requiring 5 A per diode operation, either part is suitable. For applications where higher current capacity or reduced thermal dissipation is beneficial, the STPS16170CG-TR is the appropriate selection. Both parts maintain Active product status and are suitable for new design implementation.

Q: Are there any temperature operating range differences?

A: The VB10170C-E3/8W specifies -40°C to 175°C junction operating temperature. The STPS16170CG-TR specifies 175°C maximum junction temperature. Both parts support equivalent maximum operating temperatures suitable for industrial and commercial applications.
