Q2008N4RP

Triacs Overview

The Littelfuse Q2008N4RP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current (It RMS) of 8 A and a rated repetitive peak off-state voltage (VDRM) of 200 V. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current (Ih) of 35 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 35 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 83 A or 100 A depending on conditions. Leakage current in the off-state is limited to 10 uA at VDRM.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated PCB assembly
• Bidirectional switching capability for AC load control circuits
• High thermal stability supporting operation up to +125 °C junction temperature

Triacs Applications

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

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Request original manufacturer datasheets and test reports to confirm electrical specifications match the Q2008N4RP part number. Inspect packaging integrity and check for moisture sensitivity labels prior to soldering. Ensure compliance with RoHS and REACH regulations as stated in official documentation.

Triacs Selection Notes

Select this triac when a 200 V blocking voltage and 8 A continuous current rating are required in a surface-mount form factor. Compare gate trigger characteristics against driver circuit capabilities to ensure reliable turn-on. Evaluate thermal management requirements based on the 1.6 V on-state voltage drop and expected load currents.

Triacs Part Context

This component belongs to the Littelfuse Qxx08xHx series of high-speed triacs. The series offers various voltage ratings including 400 V, 600 V, and 1000 V variants sharing similar current and package characteristics. The Q2008N4RP specifically addresses lower voltage AC control needs while maintaining the robust performance profile of the family.

Triacs Replacement Considerations

Direct replacements must match the 8 A RMS current, 200 V VDRM, and SMTO-263-2 package. Verify pinout compatibility and gate trigger parameters before substitution. Consult Littelfuse documentation for approved cross-reference lists.
