MBR1550CT-E3/45

Diode Arrays Overview

The MBR1550CT-E3/45 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 7.5 A per diode, totaling 15 A for the device. The component utilizes a TO-220AB through-hole package with matte tin-plated leads. Electrical characteristics include a maximum instantaneous forward voltage of 0.65 V at 7.5 A and a maximum reverse current of 1.0 mA at rated blocking voltage. Operating junction temperature ranges from -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The E3 suffix indicates consumer grade material compliant with JESD 201 class 1A whisker testing standards. Confirm that the TO-220AB package variant matches the intended mechanical mounting constraints and thermal dissipation needs for the target design.

Diode Arrays Selection Notes

Select this component when a dual common-cathode configuration is required for synchronous rectification or polarity protection. Ensure the circuit operates within the 50 V reverse voltage limit and 7.5 A per diode current rating. Consider the thermal resistance values for heatsinking requirements if operating near the maximum junction temperature limits under continuous load conditions.

Diode Arrays Part Context

This part belongs to the MBR(F,B)15xxCT series of dual common-cathode Schottky rectifiers from Vishay. The series includes variants with different voltage ratings such as 35 V, 45 V, and 60 V. All members share similar electrical characteristics regarding forward voltage and surge current capabilities while differing primarily in their maximum repetitive peak reverse voltage specifications.

Diode Arrays FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 150 A per diode for an 8.3 ms single half sine-wave superimposed on rated load.

Does the E3 suffix affect the electrical performance compared to standard versions?

No, the E3 suffix denotes consumer grade material that meets JESD 201 class 1A whisker test requirements but does not alter the electrical parameters defined in the datasheet.

What is the isolation voltage for the TO-220AB package?

Isolation voltage specifications are provided only for the ITO-220AB package, which offers 1500 VAC from terminal to heatsink. The standard TO-220AB package does not list an isolation voltage rating.
