Q4010N5TP

Triacs Overview

The Littelfuse Q4010N5TP is a bidirectional triac 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 operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. Non-repetitive peak on-state currents are specified at 100 A and 120 A, with an off-state leakage current of 10 uA under VDRM conditions.

Triacs Feature Summary

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

Triacs Applications

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

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm RoHS compliance status via official datasheets prior to integration. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines to prevent package degradation during soldering processes.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 400 V blocking voltage are required in a surface-mount form factor. Compare against the Q4012NH5RP for reel packaging options or the Q4025N5TP for higher current capacity. Verify gate trigger requirements match the driving circuit capabilities, as the 50 mA holding current may influence latch-up behavior in specific loads.

Triacs Part Context

This part belongs to the Littelfuse Qxx10xx series of thyristors. It serves as a high-current alternative to lower-rated triacs while offering a compact footprint compared to through-hole equivalents. The series provides standardized pinouts and thermal characteristics for consistent design implementation across various power control platforms.

Triacs Replacement Considerations

Direct substitutes include the Q4012NH5RP for similar electrical ratings with different packaging. For higher current needs, the Q4025N5TP offers compatible voltage ratings with increased amperage. Verify pinout compatibility and thermal resistance values before substituting to ensure circuit integrity.
