Substitute Part Grouping Explanation

Substitution of the VS-STPS40L40CW-N3 is determined by strict equivalence across the following critical parameters:

• Diode Configuration: Must be 1 Pair Common Cathode
• Technology: Must be Schottky
• Voltage - DC Reverse (Vr) (Max): Must be 40 V
• Current - Average Rectified (Io) (per Diode): Must be 40 A
• Voltage - Forward (Vf) (Max) @ If: Must be 590 mV @ 40 A
• Speed: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: Must be TO-247-3
• Mounting Type: Must be Through Hole

The substitute part VS-40CPQ040-N3 meets all these criteria and is therefore classified as a parametric equivalent. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, share identical electrical ratings, and are housed in the same TO-247-3 package configuration.

Parameter Comparison

Engineering Selection Recommendations

Both VS-STPS40L40CW-N3 and VS-40CPQ040-N3 are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Both carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

The parts are electrically and mechanically equivalent across all primary substitution criteria: voltage rating, current rating, forward voltage drop, switching speed, package type, and mounting configuration. Selection between these two parts may be based on inventory availability, lead time, or specific application requirements related to reverse leakage current characteristics or maximum junction temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can VS-40CPQ040-N3 be used as a direct replacement for VS-STPS40L40CW-N3?

A: Yes. Both parts share identical electrical ratings (40 V, 40 A), the same Schottky technology, identical forward voltage characteristics, and are packaged in the same TO-247-3 through-hole configuration. Both are Active status products with ROHS3 compliance.

Q: What are the differences between these two parts?

A: The primary differences are reverse leakage current (VS-STPS40L40CW-N3: 800 µA @ 40 V; VS-40CPQ040-N3: 4 mA @ 40 V) and maximum junction temperature specification (VS-STPS40L40CW-N3: -55°C to 150°C; VS-40CPQ040-N3: 150°C maximum). These differences do not affect substitution eligibility for applications within the specified operating parameters.

Q: Are there any package or pinout differences?

A: No. Both parts use the TO-247-3 package with identical through-hole mounting configuration and pin arrangement.

Q: Do both parts meet RoHS and environmental compliance requirements?

A: Yes. Both VS-STPS40L40CW-N3 and VS-40CPQ040-N3 are ROHS3 Compliant and REACH Unaffected.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.
