VS-VSKD71/10

Diode Arrays Overview

The VS-VSKD71/10 is a high-voltage power diode module from the VSK.71 series, manufactured by Vishay Semiconductors. It utilizes the AAP Gen 7 (TO-240AA) package and features a doubler circuit configuration with two internal diodes. The device supports a maximum repetitive peak reverse voltage of 1000 V and handles a maximum average forward current of 80 A at a case temperature of 110 °C. Key electrical ratings include a maximum RMS forward current of 126 A and a non-repetitive surge current of 1570 A at 60 Hz. The junction-to-case thermal resistance is 0.28 °C/W per leg.

Diode Arrays Procurement Notes

Verify the specific circuit configuration code 'D' corresponds to the required doubler topology before procurement. Confirm that the mounting surface meets the flatness and smoothness requirements specified in the datasheet to achieve the typical thermal resistance value. Ensure the installation torque adheres to the recommended 4 N·m specification to maintain proper mechanical contact and thermal interface integrity.

Diode Arrays Selection Notes

Select this component when a 1000 V rating is required alongside an 80 A average current capacity in a compact TO-240AA form factor. The doubler circuit configuration distinguishes it from common cathode or single diode variants within the same series. Evaluate the thermal management strategy based on the 0.28 °C/W junction-to-case resistance and the operating temperature range of -40 °C to +150 °C.

Diode Arrays Part Context

This module belongs to the VSK.71 series, which encompasses various voltage codes ranging from 400 V to 1600 V. The series shares the AAP Gen 7 package design, offering standardized dimensions and mounting interfaces across different voltage and current ratings. This standardization facilitates easier integration into existing industrial power electronics designs requiring high-voltage rectification capabilities.

Diode Arrays Replacement Considerations

Compatible substitutes within the same family include VS-VSKD71/04 (400 V), VS-VSKD71/06 (600 V), VS-VSKD71/08 (800 V), VS-VSKD71/12 (1200 V), VS-VSKD71/14 (1400 V), and VS-VSKD71/16 (1600 V). These alternatives share identical current ratings and package dimensions but differ in their maximum repetitive peak reverse voltage specifications.
