VS-VSKN105/12

SCRs - Modules Overview

The VS-VSKN105/12 is a thyristor/diode module from the VSK.105 series, featuring an SCR and diode with common anodes in an AAP Gen 7 (TO-240AA) package. It supports a maximum repetitive peak reverse voltage of 1200 V and an average on-state current of 105 A at 85 °C case temperature. The device provides a continuous RMS current of 235 A as an AC switch and withstands non-repetitive surge currents up to 2094 A at 60 Hz. Operating within a junction temperature range of -40 °C to +130 °C, it utilizes direct bonded copper substrates for low thermal resistance.

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'N' corresponds to the required SCR/diode common anode topology. Confirm the voltage suffix '12' matches the 1200 V rating requirement. Ensure heatsink mounting torque adheres to the specified 4 Nm limit for the TO-240AA package. Validate that gate drive parameters remain within the maximum peak gate power limits defined in the datasheet.

SCRs - Modules Selection Notes

Select this component when a combined thyristor and diode solution with common anodes is required for high voltage isolation. The 105 A current rating suits general purpose industrial switching. Consider the 0.22 °C/W thermal resistance for heat sink calculations. Verify compatibility with standard fast-on tab connections for gate and main terminals.

SCRs - Modules Part Context

This part belongs to the VSK.105 series, which includes thyristor/thyristor (T), thyristor/diode positive control (H), and thyristor/diode negative control (L) variants. All share the same physical dimensions and electrical current ratings but differ in internal circuit configurations. The series is designed for robust industrial environments requiring reliable high-power switching capabilities.

SCRs - Modules Replacement Considerations

Cross-reference other VSK.105 series modules like VS-VSKH105/12 or VS-VSKL105/12 if different circuit topologies are acceptable. Verify that alternative parts maintain the same AAP Gen 7 package footprint and terminal layout for mechanical interchangeability.
