Key Parameters

Substitute Part Grouping Explanation

Substitution of the VB20150C-E3/8W is permissible when the alternative component maintains compatibility across the following critical parameters:

Configuration & Technology Requirements:

• Diode configuration must be 1 pair common cathode
• Technology must be Schottky
• Mounting type must be surface mount
• Package must be TO-263-3 D2PAK (2 Leads + Tab), TO-263AB

Electrical Parameter Compatibility:

• Maximum reverse voltage (Vr) must equal or exceed 150 V
• Average rectified current (Io) per diode must equal or exceed 10 A
• Forward voltage (Vf) characteristics must be within acceptable operating range
• Reverse leakage current must be specified at rated voltage
• Speed classification must be fast recovery (≤ 500ns, > 200mA)

Compliance & Environmental Requirements:

• RoHS3 compliance required
• Moisture sensitivity level must be 1 (Unlimited)
• Product status must be active

The STPS16170CG-TR meets all substitution criteria through equivalent package geometry, matching diode configuration, and superior electrical ratings that ensure functional compatibility within the VB20150C-E3/8W application envelope.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The STPS16170CG-TR is a valid substitute for the VB20150C-E3/8W based on electrical and mechanical compatibility. Both components are active products with RoHS3 compliance and identical moisture sensitivity classification. The substitute component features a higher maximum reverse voltage rating (170 V versus 150 V), which provides enhanced voltage margin in the application circuit.

Current Rating Consideration:

The STPS16170CG-TR is rated for 8 A average rectified current per diode, compared to the 10 A rating of the VB20150C-E3/8W. Applications requiring the full 10 A per diode specification must confirm that the substitute component's 8 A rating is sufficient for the intended circuit operation.

Forward Voltage Characteristics:

The STPS16170CG-TR exhibits a lower forward voltage drop (920 mV @ 8 A) relative to the VB20150C-E3/8W (1.2 V @ 10 A). This characteristic may result in reduced power dissipation in the application circuit.

Reverse Leakage Performance:

The STPS16170CG-TR demonstrates significantly lower reverse leakage current (15 µA @ 170 V) compared to the VB20150C-E3/8W (150 µA @ 150 V), indicating superior leakage characteristics at higher voltage rating.

Thermal Performance:

The STPS16170CG-TR supports a maximum junction temperature of 175°C, exceeding the VB20150C-E3/8W maximum of 150°C, providing additional 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-E3/8W?

A: The STPS16170CG-TR is mechanically and electrically compatible with the VB20150C-E3/8W in applications where the 8 A per diode current rating is sufficient. Both components share identical package geometry (TO-263-3 D2PAK), diode configuration (1 pair common cathode), and technology (Schottky). The substitute component's higher voltage rating (170 V) and lower reverse leakage current provide enhanced performance margins.

Q: What is the primary difference in current rating between these components?

A: The VB20150C-E3/8W is rated for 10 A average rectified current per diode, while the STPS16170CG-TR is rated for 8 A per diode. Applications operating at or near the 10 A specification must confirm that the substitute component's 8 A rating meets circuit requirements.

Q: Are both components RoHS3 compliant?

A: Yes, both the VB20150C-E3/8W and STPS16170CG-TR are RoHS3 compliant and carry moisture sensitivity level 1 (unlimited) classification, ensuring compatibility with standard manufacturing and storage protocols.

Q: How do the forward voltage characteristics compare?

A: The VB20150C-E3/8W exhibits a forward voltage of 1.2 V at 10 A, while the STPS16170CG-TR exhibits 920 mV at 8 A. The lower forward voltage of the substitute component results in reduced power dissipation per diode in the application circuit.

Q: What is the voltage rating difference?

A: The VB20150C-E3/8W has a maximum reverse voltage rating of 150 V, while the STPS16170CG-TR is rated for 170 V. The higher voltage rating of the substitute component provides additional voltage margin and is suitable for applications operating within the 150 V specification.

Q: Are the packages identical?

A: Yes, both components 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 physical replacement.

Q: What is the reverse leakage current difference?

A: The VB20150C-E3/8W exhibits reverse leakage of 150 µA at 150 V, while the STPS16170CG-TR exhibits 15 µA at 170 V. The substitute component demonstrates significantly lower leakage current, which may reduce standby power consumption in the application.

Q: Do both components support the same operating temperature range?

A: The VB20150C-E3/8W supports junction temperatures from -55°C to 150°C, while the STPS16170CG-TR supports -55°C to 175°C maximum. The substitute component provides an additional 25°C thermal margin at the upper operating limit.
