MBRF30H45CT-E3/45

Diode Arrays Overview

The MBRF30H100CT-E3/45 is a dual common cathode high voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to deliver improved high-temperature performance and low leakage current. The device is housed in an ITO-220AB (ITO-220AB) through-hole package with matte tin-plated leads. Key electrical ratings include a maximum repetitive peak reverse voltage of 100 V, a total maximum average forward rectified current of 30 A (15 A per diode), and a peak forward surge current of 275 A. Operating junction temperatures range from -65 °C to +175 °C.

Diode Arrays Procurement Notes

Verify the specific ITO-220AB package designation when sourcing replacements. Confirm RoHS compliance requirements match the E3 suffix specifications. Ensure thermal management designs account for the specified thermal resistance values under actual operating conditions rather than standard case temperature limits.

Diode Arrays Selection Notes

Select this component for applications requiring robust high-voltage handling and elevated temperature operation. The dual common cathode configuration simplifies circuit layout compared to discrete diodes. Evaluate thermal dissipation needs based on the 4.6 °C/W junction-to-case thermal resistance characteristic of the ITO-220AB package variant.
