Parameter Comparison

Engineering Selection Recommendations

The VS-MBR1535CT-M3 from Vishay General Semiconductor - Diodes Division is a direct parametric equivalent to the obsolete MBR1535CTG. All critical electrical specifications—reverse voltage, rectified current, forward voltage, recovery speed, and reverse leakage—are identical.

Mechanical Compatibility: Both parts use the TO-220-3 package with through-hole mounting, ensuring PCB footprint compatibility without layout modification.

Compliance Consideration: The MBR1535CTG carries explicit ROHS3 compliance certification. The VS-MBR1535CT-M3 compliance status is not specified in the provided data. Verification of RoHS compliance with the Vishay supplier is required for applications subject to RoHS regulatory requirements.

Temperature Range: The VS-MBR1535CT-M3 specifies a maximum junction temperature of 150°C, compared to 175°C for the MBR1535CTG. This difference does not affect substitution for applications operating within the 150°C limit. Applications requiring operation above 150°C require alternative component selection.

Part Availability: The VS-MBR1535CT-M3 is classified as active and maintains current production status, ensuring long-term availability compared to the obsolete MBR1535CTG.

Frequently Asked Questions (FAQ)

Q: Can the VS-MBR1535CT-M3 be used as a direct replacement for the MBR1535CTG?

A: Yes, the VS-MBR1535CT-M3 is a direct parametric equivalent. All electrical specifications—voltage rating, current rating, forward voltage, recovery speed, and leakage current—are identical. The TO-220-3 package is mechanically compatible with existing PCB designs.

Q: What is the difference in operating temperature range between these parts?

A: The MBR1535CTG operates from -65°C to 175°C junction temperature, while the VS-MBR1535CT-M3 operates from -65°C to 150°C. For applications operating within the 150°C limit, this difference is not functionally significant. Applications requiring operation above 150°C must use the original part or identify an alternative component.

Q: Are there packaging differences between these parts?

A: Both parts use the TO-220-3 through-hole package. The MBR1535CTG is supplied in standard packaging, while the VS-MBR1535CT-M3 is supplied in tube packaging. This difference affects handling and storage but does not impact electrical performance or PCB mounting.

Q: Is the VS-MBR1535CT-M3 RoHS compliant?

A: RoHS compliance status for the VS-MBR1535CT-M3 is not specified in the provided technical data. Contact the Vishay supplier directly to confirm RoHS3 compliance for applications subject to RoHS regulatory requirements.

Q: Why is the MBR1535CTG classified as obsolete?

A: The MBR1535CTG is no longer in active production. The VS-MBR1535CT-M3 provides equivalent electrical and mechanical functionality with active production status, ensuring component availability for new designs and field replacements.

Q: Can I use the VS-MBR1535CT-M3 in high-temperature applications above 150°C?

A: No. The VS-MBR1535CT-M3 is rated for a maximum junction temperature of 150°C. Applications requiring operation above 150°C require alternative component selection or use of the original MBR1535CTG if available from inventory.
