VBT2045C-M3/8W

Diode Arrays Overview

The VBT2045C-M3/8W is a dual low-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It utilizes TMBS technology to achieve an ultra-low forward voltage drop of 0.33 V at 5.0 A and 0.41 V at 10 A per diode. The device features a common cathode configuration in a D2PAK (TO-263AB) package, rated for a maximum repetitive peak reverse voltage of 45 V and a maximum average forward rectified current of 2 x 10 A. It supports a peak forward surge current of 160 A and operates within a junction temperature range of -40 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix /8W corresponds to the tape and reel delivery mode containing 800 units per reel. Confirm that the base part number includes the M3 designation to ensure compliance with halogen-free requirements and JESD 201 class 2 whisker testing standards. Cross-reference the document number 87956 to access the latest revision of the official datasheet before finalizing procurement specifications.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low forward voltage drops at moderate currents up to 10 A per diode. The D2PAK package provides thermal management capabilities suitable for surface mount assembly. Ensure the application voltage does not exceed the 45 V rating and verify that the thermal resistance parameters align with the system's heat dissipation requirements.

Diode Arrays Part Context

This component belongs to the VBT series of dual low-voltage Trench MOS Barrier Schottky rectifiers from Vishay. It shares the same electrical architecture as other variants in the family but differs in packaging and delivery format. The M3 suffix indicates environmental compliance, while the /8W suffix specifies the reel quantity for automated surface mount production lines.

Diode Arrays Replacement Considerations

Direct substitutes include the VBT2045C-M3/4W, which offers identical electrical characteristics but is supplied in tube packaging rather than tape and reel.
