VB40120C-M3/8W

Diode Arrays Overview

The VB40120C-M3/8W is a Schottky diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common cathode configuration housed in a surface-mount TO-263AB (D2PAK) package. The device supports a maximum repetitive reverse voltage of 120 V and an average forward current of 20 A per diode. Key electrical parameters include a maximum forward voltage of 970 mV at 15 A and a reverse leakage current of 500 µA at 120 V. It operates within a junction temperature range of -40°C to 150°C.

Diode Arrays Feature Summary

• Utilizes TMBS technology for enhanced switching performance
• Low forward voltage drop for improved efficiency
• High surge current capability
• Designed for surface mount applications

Diode Arrays Applications

• DC-DC converters
• Free-wheeling rectification
• Polarity protection circuits
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the specific suffix /8W against official datasheets to confirm reel packaging requirements, as distributor listings may vary. Ensure the component meets RoHS3 standards if required by your assembly process. Cross-reference the manufacturer part number with authorized channels to avoid counterfeit components. Confirm lead times directly with the supplier prior to ordering.

Diode Arrays Selection Notes

Select this component when a dual common cathode Schottky configuration is required in a D2PAK package. Compare the 120 V rating and 20 A current capacity against circuit demands. Consider thermal management needs due to the surface mount form factor. Evaluate alternative packages like TO-263AC if pinout differences exist in similar Vishay series products.

Diode Arrays Part Context

This part belongs to the VB series of TrenchMOS Schottky Rectifiers from Vishay. It shares architectural similarities with other VB models but differs in current ratings and package variants. The M3 suffix indicates lead-free composition compliant with EU directives. It is distinct from through-hole or single-diode variants within the broader product family.

Diode Arrays Replacement Considerations

Direct substitutes include VB40120C-M3/4W, which offers identical electrical specifications but utilizes tube packaging instead of reels. Verify that the replacement matches the TO-263AB footprint and pin configuration. Check for any updates in the manufacturing source or process change notifications.
