MBR20H100CTG-E3/45

Diode Arrays Overview

The MBR20H100CTG-E3/45 is a dual common-cathode high-voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes high barrier technology for improved high-temperature performance and features a guardring for overvoltage protection. The device is housed in a TO-220AB package with an isolated cathode tab. Key electrical parameters include a maximum repetitive peak reverse voltage of 100 V, a total maximum average forward rectified current of 20 A (10 A per diode), and a peak forward surge current of 150 A. The typical instantaneous forward voltage is 0.70 V at 20 A, with a maximum reverse current of 4.5 mA at 125 °C. The operating junction temperature range extends from -65 °C to +175 °C.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific ordering suffix E3/45 to confirm compliance with RoHS 2002/95/EC and WEEE 2002/96/EC directives. The E3 suffix indicates consumer grade meeting JESD 201 class 1A whisker test requirements. Confirm the delivery mode corresponds to tube packaging with a base quantity of 50 units per tube as specified in the manufacturer's ordering information.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a dual common-cathode configuration with a 100 V blocking capability. Ensure thermal management strategies account for the 2.0 °C/W typical thermal resistance per diode. Validate that the application current does not exceed the 10 A rating per leg under expected case temperatures, utilizing the forward derating curve for accurate sizing.

Diode Arrays Part Context

This part belongs to the MBR20H series of dual common-cathode Schottky rectifiers from Vishay. It shares the same physical footprint and general electrical architecture as the MBR20H90CTG variant, differing primarily in the maximum repetitive peak reverse voltage rating. The series is characterized by its plastic encapsulation meeting UL 94V-0 flammability ratings and matte tin plated leads.

Diode Arrays Replacement Considerations

The datasheet lists the MBR20H90CTG as a related part within the same family, distinguished only by a lower 90 V reverse voltage rating. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
