Triacs datasheet and documents for QK006R5
Triacs Overview
The Littelfuse QK006R5 is a standard TRIAC designed for high-voltage AC switching applications. It features a rated repetitive off-state voltage of 1 kV and an on-state RMS current capability of 6 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a maximum gate trigger voltage of 1.3 V, a holding current of 50 mA, and a non-repetitive peak on-state current of 80 A.
Triacs Feature Summary
- High voltage blocking capability suitable for industrial power control
- Robust thermal performance with extended operating temperature range
- Standardized through-hole mounting for reliable PCB integration
Triacs Applications
- Industrial motor speed control systems
- Solid-state relay modules
- General purpose AC power switching circuits
Triacs Procurement Notes
Verify component authenticity through authorized Littelfuse channels or certified distributors. Confirm RoHS compliance status and check for obsolescence notices, as availability may be limited. Ensure the specific lot date code meets project requirements before finalizing orders.
Triacs Selection Notes
Select this component when a 1 kV rating and 6 A continuous current are required in a through-hole format. Consider the 1.3 V gate trigger sensitivity for driver compatibility. Evaluate thermal management needs given the TO-220 package constraints for high-power dissipation scenarios.
Triacs Part Context
This part belongs to the Qxx06xx series of TRIACs from Littelfuse. It shares core electrical specifications with variants like the QK006L5 but differs in packaging and manufacturing details. The series is designed for general-purpose thyristor applications requiring reliable AC switching.
Triacs Replacement Considerations
Direct substitutes include the QK006L5, which offers identical electrical ratings but uses a different package configuration. Verify pinout compatibility and mechanical dimensions before swapping components in existing designs.
