Scrs datasheet and documents for VS-111RKI120M
Scrs Overview
The VS-111RKI120M is a Silicon Controlled Rectifier (SCR) thyristor manufactured by Vishay General Semiconductor. It is housed in the TO-83/94 SQ package and features lead-free termination compliant with RoHS standards. The device is rated for a maximum repetitive peak off-state voltage of 1200 V and a gate trigger current of 50 mA. It supports a high on-state current capacity of 110 A, making it suitable for robust power control applications requiring reliable switching performance.
Scrs Feature Summary
- High thermal stability and rugged construction for demanding environments
- Lead-free terminal finish ensuring environmental compliance
- Fast turn-on capability for efficient power switching
Scrs Applications
- Industrial motor drives
- Power supply circuits
- Lighting control systems
Scrs Procurement Notes
Verify the specific suffix 'SQ-e3' against official datasheets to confirm lead-free status and package dimensions. Ensure the ordering part number matches the exact electrical ratings required for the design. Confirm availability through authorized distributors as stock levels fluctuate. Validate that the TO-83/94 footprint aligns with the PCB layout constraints before finalizing procurement.
Scrs Selection Notes
Select this component when a 1200 V blocking voltage and 110 A on-state current are required in a compact TO-83/94 form factor. Consider the 50 mA gate trigger requirement for driver circuit compatibility. Evaluate thermal management needs based on the 110 A load current and ambient operating conditions. Compare against alternative SCR packages if space or mounting style differs from the standard SQ configuration.
Scrs Part Context
This SCR belongs to Vishay's general-purpose thyristor lineup designed for industrial power applications. The TO-83/94 package offers a balance of current handling and physical size. Vishay emphasizes quality and reliability in its discrete semiconductor products, targeting sectors like industrial automation and energy conversion where consistent performance under stress is critical.
Scrs Replacement Considerations
Consult official substitution guides for equivalent 1200 V, 110 A SCRs in TO-83/94 packages. Verify pinout compatibility and thermal characteristics before swapping manufacturers. Generic replacements may differ in gate sensitivity or holding current.
