Q4010L5TP

Triacs Overview

The Littelfuse Q4010L5TP is a bidirectional triac belonging to the Qxx10xx series, designed for AC power control applications. It features a rated repetitive peak off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 10 A. The device exhibits a maximum gate trigger current (IGT) of 50 mA and maintains a low on-state voltage of 1.6 V. Off-state leakage current is specified at 10 uA under VDRM conditions. The component is housed in a TO-220-2 package, facilitating through-hole mounting for industrial thermal management.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• High current handling with 10 A RMS rating
• Low conduction loss characterized by 1.6 V on-state voltage
• Robust packaging suitable for high-power thermal dissipation

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuitry

Triacs Procurement Notes

Verify the specific Littelfuse datasheet revision to confirm exact thermal resistance values and absolute maximum ratings before finalizing the design. Ensure the TO-220-2 mounting interface matches the target PCB footprint and that the 400 V voltage rating aligns with the system's peak line voltage requirements.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 10 A continuous current capacity are required in a standard TO-220-2 form factor. Consider the 50 mA gate drive requirement for driver compatibility. Evaluate thermal management needs based on the 1.6 V forward drop at full load to determine appropriate heatsinking strategies.

Triacs Part Context

This part belongs to the Littelfuse Qxx10xx series of thyristors, which are engineered for general-purpose AC power switching. The series offers various voltage and current combinations within standardized packages to simplify inventory management for designers working on industrial power control hardware.

Triacs Replacement Considerations

Consult official Littelfuse cross-reference documentation for verified equivalent parts. Do not substitute based solely on matching electrical parameters without confirming pinout compatibility and thermal characteristics.
