Q4010R5TP

Triacs Overview

The Littelfuse Q4010R5TP is a bidirectional triac from the Qxx10xx series, designed for AC switching and phase control applications. It features a TO-220-2 through-hole package with an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device supports non-repetitive peak on-state currents of 100 A or 120 A depending on specific conditions. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. It exhibits an on-state voltage of 1.6 V and a leakage current of 10 uA at VDRM. The component operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated gate-controlled bidirectional AC switching capability for versatile phase control
• Electrically isolated TO-220-2 package construction for simplified mounting
• Glass-passivated junctions ensuring long-term parameter stability

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing. Confirm RoHS compliance status and REACH SVHC declarations directly from the manufacturer's official documentation prior to integration. Ensure the selected variant matches the required gate trigger characteristics for the intended driver circuit design.

Triacs Selection Notes

Select this component for designs requiring a 10 A RMS current rating in a through-hole configuration. Verify that the 400 V blocking voltage meets the system's peak line voltage requirements. Consider the 50 mA holding current limit to ensure reliable latching during low-load operation phases.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx10xx series of triacs. These devices are engineered for general-purpose AC power control where moderate current handling and robust thermal performance are necessary. The series utilizes glass-passivated junction technology to maintain reliability under standard industrial operating conditions.

Triacs Replacement Considerations

Direct substitutes within the same series include variants with different voltage ratings or current capacities, such as the Q4012NH5RP for surface mount needs. Cross-package replacements require verification of pinout compatibility and thermal dissipation capabilities.
