MBRB20H35CTHE3/81

Diode Arrays Overview

The MBRB20H35CTHE3/81 is a Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a dual common-cathode configuration in a D2PAK-3 (TO-263-3) surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 35 V and an average forward rectified current of 20 A per anode. Key electrical characteristics include a low forward voltage drop, high surge current capability, and operation over a junction temperature range from -65°C to +150°C.

Diode Arrays Feature Summary

• Dual common-cathode configuration for efficient bridge-less or center-tapped applications
• Low forward voltage drop reduces power losses and increases system efficiency
• Guardring technology provides enhanced overvoltage protection and reliability
• High thermal performance suitable for high-frequency switching mode power supplies

Diode Arrays Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in DC-to-DC converters
• Polarity protection circuits in electronic systems

Diode Arrays Procurement Notes

Verify the specific suffix HE3 against official Vishay documentation to confirm halogen-free status and RoHS compliance details. Confirm availability status as components may be subject to end-of-life notices or limited distribution channels. Ensure the ordering part number matches the exact package and pinout requirements for your PCB design.

Diode Arrays Selection Notes

Select this component when a dual common-cathode Schottky rectifier is required for low-voltage, high-current applications. The 35 V rating suits 12 V or 24 V bus architectures. The TO-263-3 package offers robust thermal dissipation compared to smaller SMD packages. Verify that the 20 A current rating meets the peak load requirements of the target circuit.

Diode Arrays Part Context

This part belongs to the MBRB series of high-current density Schottky rectifiers from Vishay. The series utilizes silicon planar technology optimized for low forward voltage and fast recovery characteristics. The MBRB20H35 variant specifically targets applications requiring higher current handling within a compact surface-mount footprint.
