MBR2550CTHE3/45

Diode Arrays Overview

The MBR2550CTHE3/45 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 50 V and a total maximum average forward rectified current of 25 A, with 12.5 A per diode. The device has a peak forward surge current rating of 150 A and operates within a junction temperature range of -65 °C to +150 °C. Electrical characteristics include a maximum instantaneous forward voltage of 0.75 V at 15 A and 0.82 V at 30 A (TC = 25 °C), and a maximum reverse current of 0.2 mA at 25 °C. It utilizes a TO-220AB package.

Diode Arrays Procurement Notes

Verify the specific suffix HE3 indicates high reliability grade qualification against JESD 201 class 2 whisker test standards. Confirm the /45 suffix corresponds to the tube delivery mode and base quantity of 50 units. Ensure the component meets RoHS 2002/95/EC directives and WEEE 2002/96/EC compliance requirements before procurement.

Diode Arrays Selection Notes

Select this component when a dual common-cathode configuration is required for low voltage applications. The TO-220AB package supports mounting torques up to 10 in-lbs. Verify thermal resistance requirements, as the junction-to-case thermal resistance is 1.5 °C/W per diode. Ensure the operating environment stays within the specified storage and junction temperature limits.
