Overview
The IRKH91/06A is a silicon-controlled rectifier (SCR) manufactured by Vishay General Semiconductor. It features a TO-240AA flange-mount package with an isolated case connection. The device is rated for a maximum repetitive peak reverse voltage of 600 V and a maximum on-state current of 95 A. It supports a non-repetitive peak forward current of 2094 A and operates within a junction temperature range of -40 °C to +125 °C.
Feature Summary
- High-power thyristor construction utilizing silicon technology
- Isolated flange mount design for efficient thermal management
- Robust surge current handling capability for industrial loads
Applications
- Industrial motor control systems
- Power supply circuits
- Inverter applications
Procurement Notes
Verify the specific suffix 'A' against official Vishay documentation to confirm exact electrical tolerances and pinout configurations, as variations may exist within the VS-VSKH91 series. Ensure the procurement channel provides original manufacturer traceability to avoid counterfeit components in high-voltage power applications.
Selection Notes
Select this component when a 600 V blocking voltage and 95 A continuous current rating are required in a standard TO-240AA form factor. Consider the 2094 A surge capacity for inrush current scenarios. Verify that the mounting interface accommodates the isolated case requirement for proper grounding and thermal dissipation in the target assembly.
Part Context
This SCR belongs to the Vishay VS-VSKH91 series of high-power thyristors. These devices are designed for demanding power electronics environments requiring reliable switching and high current density. The TO-240AA package is a standard industry footprint for medium-to-high power discrete semiconductors.
Replacement Considerations
Cross-reference with other Vishay VS-VSKH91 variants or equivalent 600 V / 95 A SCRs in TO-240AA packages from other manufacturers. Confirm that gate trigger characteristics and thermal resistance values match the original design requirements before substitution.
