MBRB2035CTHE3/81

Diode Arrays Overview

The MBRB2035CTHE3/81 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the D2PAK (TO-263AB) surface-mount package and incorporates Guardring technology for overvoltage protection. The device is AEC-Q101 qualified, featuring matte tin-plated leads that meet JESD 201 class 2 whisker test requirements. Key electrical parameters include a maximum repetitive peak reverse voltage of 45 V, a total maximum average forward rectified current of 20 A (10 A per diode), and a peak forward surge current of 150 A per diode.

Diode Arrays Feature Summary

• Guardring structure provides enhanced overvoltage protection capabilities
• Low forward voltage drop contributes to high efficiency and low power loss
• High forward surge capability supports robust operation under transient conditions
• AEC-Q101 qualification ensures suitability for automotive applications

Diode Arrays Applications

• Free-wheeling diodes in DC/DC converter circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm compliance with RoHS directives and AEC-Q101 automotive qualification standards. Ensure the selected variant matches the required packaging format, such as tape and reel or tube, to align with assembly line specifications. Cross-reference the component marking with the datasheet to validate authenticity and correct part identification before procurement.

Diode Arrays Selection Notes

Select this component for designs requiring a dual common cathode configuration in a surface-mount footprint. Evaluate thermal management requirements based on the junction-to-case thermal resistance provided in the datasheet. Confirm that the operating junction temperature range meets the environmental constraints of the target application. Verify that the reverse voltage rating exceeds the maximum expected circuit voltage with appropriate safety margins.

Diode Arrays Part Context

This component belongs to the MBRB20xxCT series of dual common cathode Schottky rectifiers from Vishay. The series offers various voltage ratings, including 45 V and 60 V options, packaged in ITO-220AB and D2PAK (TO-263AB) formats. The HE3 suffix indicates an AEC-Q101 qualified, RoHS-compliant version designed for automotive environments, distinguishing it from commercial grade variants within the same product family.

Diode Arrays Replacement Considerations

Compatible substitutes within the same Vishay series include the MBRB2045CTHE3 and MBRB2060CTHE3. These alternatives share identical pinouts and mechanical dimensions but differ in maximum repetitive peak reverse voltage ratings. Verify that the alternative voltage rating satisfies the specific circuit requirements before substitution.
