VS-VSKJ71/10

Diode Arrays Overview

The VS-VSKJ71/10 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 two-diodes common anode circuit configuration. 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 temperature range spans from -40 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific circuit configuration code 'J' corresponds to the required two-diodes common anode topology before procurement. Confirm that the 1000 V voltage rating aligns with system requirements. Ensure mounting hardware complies with the specified M5 x 0.8 screw torque guidelines. Validate thermal interface material compatibility for the recommended mounting surface conditions.

Diode Arrays Selection Notes

Select this component when a common anode dual diode arrangement is necessary within a single module footprint. The TO-240AA package facilitates easy heatsink mounting compared to discrete components. Consider the 0.28 °C/W internal thermal resistance per leg for heat dissipation calculations. Verify that the 1570 A surge capability meets the inrush current demands of the target application circuit.

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 same mechanical dimensions and thermal characteristics across different voltage ratings. The 'J' suffix denotes the specific internal wiring configuration, distinguishing it from doubler, common cathode, or single diode variants within the same physical package family.

Diode Arrays Replacement Considerations

Direct replacements must match the 1000 V rating, 80 A current capacity, and common anode configuration. Alternative modules should utilize the identical AAP Gen 7 (TO-240AA) package to ensure mechanical interchangeability without modifying the heatsink or PCB layout.
