Q4016NH4RP

Triacs Overview

The Littelfuse Q4016NH4RP is a bidirectional triac designed for AC switching and phase control applications. It features an RMS on-state current of 16 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 surface-mount package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2 V, and a gate trigger current of 35 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A, with an on-state voltage of 1.6 V and a leakage current of 5 uA.

Triacs Feature Summary

• Integrated bidirectional AC switch suitable for phase control circuits
• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High thermal stability supporting operation up to 125°C

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official datasheet to confirm reel packaging specifications and quantity per unit. Ensure compatibility with the required SMTO-263-2 footprint during PCB layout. Confirm RoHS compliance status through the latest environmental documentation provided by Littelfuse before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 16 A RMS current rating and 400 V blocking voltage are required in a surface-mount form factor. Compare gate trigger requirements, specifically the 35 mA current threshold, against available driver capabilities. Evaluate thermal management needs given the 125°C maximum junction temperature limit and the specific power dissipation characteristics of the SMTO-263-2 package.

Triacs Part Context

This part belongs to the Qxx16xHx series of Triacs manufactured by Littelfuse under the Teccor brand. The series is characterized by glass-passivated junctions for parameter stability. These devices are engineered as bidirectional switches for general-purpose AC control applications where reliable performance and noise immunity are critical design factors.

Triacs Replacement Considerations

Direct substitutes within the same series include Q4008NH4RP and Q4012NH5RP. Verify that the alternative part's current rating meets or exceeds the 16 A requirement. Check if the gate trigger characteristics of the substitute are compatible with the existing drive circuitry.
