Q4010N4TP

Triacs Overview

The Littelfuse Q4010N4TP is a bidirectional triac belonging to the Qxx10xx series, designed for AC switching and phase control applications. It features an on-state RMS current capacity of 10A and a maximum repetitive peak off-state voltage (VDRM) of 400V. The device utilizes a TO-220-2 package with electrical isolation from the mounting surface. Key electrical parameters include a holding current range of 25mA to 25mA, a gate trigger voltage of 1.6V, and a maximum off-state leakage current of 10µA at VDRM. The component operates within a standard temperature range typical for thyristors.

Triacs Feature Summary

• Integrated diac structure for simplified triggering in Quadrac configurations
• Electrically isolated TO-220 package eliminating need for external insulators
• 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 suffix 'N4' against official Littelfuse documentation to confirm pinout orientation and thermal characteristics. Ensure the selected variant matches the required isolation voltage rating for the target application safety standards. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing specifications.

Triacs Selection Notes

Select this component when a combined triac-diac solution is preferred over discrete assembly to reduce board space and cost. Confirm that the 400V voltage rating aligns with the peak line voltage plus transient margins. Verify that the TO-220-2 package fits the available thermal management infrastructure and mounting constraints.

Triacs Part Context

This part belongs to the Teccor Qxx10xx series of Quadracs manufactured by Littelfuse. These devices integrate a diac trigger directly into the triac package. The series is engineered for robust AC switching performance. The Q4010N4TP specifically denotes the 10A current rating and 400V blocking capability within this family.
