QK015N5RP

Triacs Overview

The Littelfuse QK015N5RP is a bidirectional triac from the Teccor Qxx15xx series, designed for AC switching and phase control applications. It features an RMS on-state current of 15 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a low on-state voltage of 1.6 V and a maximum holding current of 70 mA. Gate triggering requirements specify a voltage of 2.5 V and currents ranging from 50 mA to 75 mA. It operates within a temperature range of -40°C to +125°C and is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• Integrated gate-controlled bidirectional AC switch suitable for noise-immune environments
• Glass-passivated junctions ensure long-term parameter stability and reliability
• Surface-mount construction facilitates automated assembly processes

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid traceability data. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing orders.

Triacs Selection Notes

Select this component when an 800 V rating is required with a 15 A continuous load capacity in a surface-mount form factor. Compare the 50 mA to 75 mA gate trigger current against available driver capabilities. Evaluate thermal management needs given the 125°C maximum operating limit and the specific thermal resistance of the SMTO-263-2 package.

Triacs Part Context

This part belongs to the Teccor Qxx15xx series of high-performance triacs manufactured by Littelfuse. The series is characterized by robust glass-passivated junction technology and is widely utilized in industrial and consumer AC power control circuits requiring reliable switching performance.

Triacs Replacement Considerations

Direct substitutes include the QK015N5TP and Q8015N5RP. Verify package compatibility and exact gate trigger specifications when cross-referencing these alternatives.
