MBRF20H100CT-E3/45

Diode Arrays Overview

The MBRF20H100CT-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 an ITO-220AB package with matte tin plated leads. 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 250 A. Typical instantaneous forward voltage is 0.64 V at 10 A and 125 °C, while maximum reverse current is 4.5 μA at 25 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix E3/45 corresponds to the tube delivery mode and commercial grade RoHS compliance. Confirm the ITO-220AB package designation matches the required isolation voltage and mounting torque specifications for the target assembly. Ensure technical validation is performed for each customer application as parameters may vary.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for 100 V applications. The ITO-220AB package provides isolation voltage capabilities not present in standard TO-220AB variants. Consider the thermal resistance and junction temperature limits for heat dissipation requirements in high frequency environments.
