Q8016NH4TP

Triacs Overview

The Littelfuse Q8016NH4TP is a bidirectional triac belonging to the Qxx16xHx series, designed for surface-mount applications in the SMTO-263-2 package. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum holding current of 50 mA, with gate trigger parameters specified at 2 V and 35 mA. Non-repetitive peak currents are rated at 167 A and 200 A under different conditions. Operating within a temperature range of -40°C to +125°C, it maintains a low on-state voltage of 1.6 V and a leakage current of 5 µA.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated assembly integration
• High-voltage blocking capability suitable for demanding AC power control environments
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

• Solid-state relay modules requiring compact switching elements
• Industrial motor speed control circuits
• Lighting dimmer systems for commercial or residential use

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid traceability records. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing orders.

Triacs Selection Notes

Select this component when a surface-mount triac with 800 V blocking voltage is required. Compare the 16 A RMS rating against circuit load requirements. Verify that the gate trigger current of 35 mA aligns with the driving circuit capabilities. Consider the SMTO-263-2 footprint constraints during PCB layout design.

Triacs Part Context

This part belongs to the Qxx16xHx family of high-performance triacs from Littelfuse. The series is characterized by robust surge handling and reliable switching in compact packages. It serves as a specialized solution for modern electronics where space efficiency and high voltage isolation are critical design parameters.

Triacs Replacement Considerations

Cross-reference with Q8016NH3RP for similar specifications but verify differences in gate trigger current and holding current. Ensure mechanical compatibility with the SMTO-263-2 footprint when substituting.
