IRKD71/16A

Diode Arrays Overview

The IRKD71/16A is a high-voltage standard diode module from the IRK.71 series, manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the ADD-A-PAK GEN V package with a TO-240AA footprint and features two diodes in series configuration. The device supports a maximum repetitive peak reverse voltage of 1600V and provides an average forward current rating of 80A at a case temperature of 100°C. Key electrical characteristics include a maximum RMS forward current of 126A and a peak non-repetitive surge current of 1790A at 50Hz. The junction temperature range spans from -40°C to 150°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'D' confirms the dual-diode series circuit configuration as defined in the manufacturer's documentation. Confirm that the '16' code corresponds to the 1600V voltage rating and 'A' indicates Generation V packaging. Ensure compliance with industrial level qualification standards required for the intended application environment before finalizing procurement.

Diode Arrays Selection Notes

Select this component when high voltage isolation and robust surge capability are required in a compact industrial package. The ADD-A-PAK GEN V design offers compatibility with standard TO-240AA mounting holes while providing increased tolerance for heatsink surface roughness. Consider the 3500VRMS isolation voltage for applications requiring significant potential difference between the circuit and the grounded heatsink.

Diode Arrays Part Context

This module belongs to the IRK.56 and IRK.71 series of standard diodes within the ADD-A-PAK GEN V product line. The series is characterized by its silicon construction and screw-mount installation style. The IRKD71/16A specifically represents the higher current variant (IRK.71) with a dual-series internal topology, distinguishing it from single-diode or common-cathode configurations available in the same family.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include the IRKC71/16A (common cathode) or IRKE71/16A (single diode), provided the circuit topology allows for the change. Cross-brand replacements must match the 1600V rating, 80A average current, and TO-240AA mechanical dimensions.
