Q8016NH4RP

Triacs Overview

The Littelfuse Q8016NH4RP is a bidirectional triac designed for surface-mount applications in the SMTO-263-2 package. It features an RMS on-state current (It RMS) of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a low on-state voltage of 1.6 V and a maximum holding current (Ih) of 50 mA. Gate triggering requirements include a voltage (Vgt) of 2 V and a current (Igt) of 35 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different conditions. Leakage current in the off-state is limited to 5 uA at VDRM. The component operates within a temperature range of -40 C to +125 C.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High thermal stability with operation up to +125 C junction temperature
• Low gate trigger current for efficient control circuit interfacing
• Robust non-repetitive surge current handling capability

Triacs Applications

• Solid-state relay modules requiring high isolation and switching
• AC motor speed control circuits for industrial equipment
• Lighting dimmer applications for commercial or residential use
• General-purpose AC power switching in consumer appliances

Triacs Procurement Notes

Verify the specific suffix 'H4' against the manufacturer's datasheet to confirm gate characteristics, as variations exist within the Qxx16xHx series. Ensure the ordering quantity aligns with the standard reel packaging configuration provided by authorized distributors. Confirm RoHS compliance status through official documentation prior to final procurement decisions.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current rating are required in a surface-mount form factor. Compare gate trigger parameters against the driving circuit capabilities, specifically noting the 35 mA Igt requirement. Evaluate thermal management needs given the 125 C maximum operating temperature limit and the thermal resistance inherent to the SMTO-263-2 package.

Triacs Part Context

This part belongs to the Littelfuse Qxx16xHx series of high-power triacs. It shares the 16 A current rating and 800 V voltage class with other variants like the Q8016NH3RP, but differs in gate sensitivity and holding current specifications. The series is engineered for robust performance in AC power control environments where reliable switching and surge tolerance are critical design factors.

Triacs Replacement Considerations

The Q8016NH3RP is a related variant within the same series offering different gate trigger characteristics. Verify pinout compatibility and thermal performance before substitution. Other manufacturers may offer equivalent 800 V/16 A SMD triacs, but gate parameters must be matched to ensure proper circuit functionality.
