Q4015N5RP

Triacs Overview

The Littelfuse Q4015N5RP is a bidirectional triac in the Teccor Qxx10xx series, designed for surface-mount applications. It features an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device supports non-repetitive on-state currents of 100 A or 120 A depending on conditions, with a maximum holding current of 50 mA. Gate triggering parameters include 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 utilizes an SMTO-263-2 package.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated PCB assembly
• High thermal stability supporting operation up to +125°C junction temperature
• Sensitive gate triggering capability for direct microprocessor interface

Triacs Applications

• Solid-state relay circuits
• AC motor speed control systems
• Lighting dimmer modules

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q4015N5RP with official Littelfuse documentation. Confirm the specific suffix RP indicates reel packaging. Ensure compliance with RoHS and REACH standards as listed in the datasheet before integration into final assemblies.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 10 A continuous current rating are required in a surface-mount form factor. Compare gate trigger current specifications against driver capabilities to ensure reliable switching. Verify that the SMTO-263-2 footprint matches the target PCB layout constraints.

Triacs Part Context

This triac belongs to the Littelfuse Teccor Qxx10xx family, which provides general-purpose AC switching solutions. The Q4015N5RP variant specifically addresses the need for compact, high-current AC control in modern electronics where through-hole mounting is impractical.

Triacs Replacement Considerations

Direct substitutes may include other 400 V, 10 A triacs in SMTO-263-2 packages from Littelfuse or competitors, provided gate characteristics and thermal ratings align with the original design requirements.
