VS-VSKC91/14

Diode Arrays Overview

The Vishay VS-VSKC91/14 is a high-voltage power diode module from the VSK91 series, housed in an ADD-A-PAK (TO-240AA) package. It features a two-diode common cathode configuration with a maximum repetitive peak reverse voltage of 1400 V and a maximum average forward current of 100 A at a case temperature of 112 °C. The device supports a non-repetitive surge current of up to 2115 A at 60 Hz and operates within a junction temperature range of -40 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific circuit configuration code 'C' corresponds to the required two-diode common cathode topology. Confirm that the mounting surface is flat, smooth, and greased to achieve the typical thermal resistance value of 0.1 °C/W. Ensure the application environment remains within the specified storage and operating temperature limits of -40 °C to +150 °C.

Diode Arrays Selection Notes

Select this component when a robust industrial-grade solution is needed for general purpose high voltage rectification. The TO-240AA package facilitates easy heatsink mounting. Consider the 1400 V rating for applications requiring significant blocking voltage capability while maintaining a compact footprint compared to discrete solutions.

Diode Arrays Part Context

This module belongs to the VSK91 series, which includes variants with different voltage ratings ranging from 400 V to 1600 V. All members share the same physical dimensions and thermal characteristics but differ in their electrical blocking capabilities. The VS-VSKC91/14 specifically denotes the 1400 V variant within this standardized family.

Diode Arrays Replacement Considerations

Direct replacements must match the 1400 V rating, 100 A current capacity, and the two-diode common cathode configuration. Verify that any substitute part utilizes the identical ADD-A-PAK (TO-240AA) mechanical outline to ensure compatibility with existing mounting hardware and PCB layouts.
