MBRB3035CT-E3/81

Diode Arrays Overview

The Vishay MBRB3035CT-E3/81 is a dual common cathode Schottky rectifier in the D2PAK (TO-263AB) surface-mount package. It features a maximum repetitive peak reverse voltage of 35 V and a total average forward rectified current of 30 A, with 15 A per diode. The device exhibits a low forward voltage drop of 0.60 V at 20 A and 125 °C case temperature. It supports a peak forward surge current of 200 A per diode and operates within a junction temperature range of -65 to +150 °C.

Diode Arrays Feature Summary

• Guardring structure provides enhanced overvoltage protection capabilities
• Low forward voltage drop ensures high efficiency and reduced power loss
• High frequency operation suitable for switching mode applications
• AEC-Q101 qualified for automotive reliability standards

Diode Arrays Applications

• Freewheeling diodes in DC/DC converters
• Polarity protection circuits
• Low voltage, high frequency rectifiers in switching mode power supplies

Diode Arrays Procurement Notes

Verify the specific E3 suffix indicates RoHS compliance and commercial grade material categorization. Confirm the /81 packaging code corresponds to tape and reel delivery with a base quantity of 800 units. Ensure the component meets JESD 201 class 1A whisker test requirements for matte tin plated leads before final integration.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for space-constrained designs. The D2PAK package offers thermal performance comparable to through-hole options while enabling automated surface-mount assembly. Consider the 35 V rating for low-voltage output stages where standard silicon rectifiers would incur excessive conduction losses.

Diode Arrays Part Context

This part belongs to the MBR(F,B)30x5CT family of dual common cathode Schottky rectifiers from Vishay General Semiconductor. The series includes variants with different voltage ratings such as 45 V models. The TO-263AB package variant provides a compact footprint suitable for high-density PCB layouts compared to larger through-hole packages.

Diode Arrays Replacement Considerations

MBRB3045CT-E3/81 shares the same package and pinout but offers a higher 45 V reverse voltage rating. Verify that the increased voltage capability does not impact circuit design constraints or thermal management requirements during substitution.
