Q2016NH4RP

Triacs Overview

The Littelfuse Q2016NH4RP is a high-voltage bidirectional triac designed for surface-mount applications. It features an RMS on-state current of 20 A and a rated repetitive off-state voltage (VDRM) of 1 kV. 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 current of 35 mA, and a typical on-state voltage of 1.6 V. Non-repetitive peak on-state currents are specified at 83 A and 100 A. The component is supplied in reel packaging with a factory quantity of 500 units.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding power control environments
• Surface-mount construction optimized for automated PCB assembly processes
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-power lighting dimming circuits

Triacs Procurement Notes

Verify the specific manufacturer datasheet for the Q2016NH4RP to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure that the ordering suffix matches the required tape-and-reel configuration. Cross-reference the part number with official Littelfuse documentation to validate RoHS compliance status and lead time requirements for production planning.

Triacs Selection Notes

Select this component when a 1 kV rating and 20 A continuous current capacity are required in a compact surface-mount form factor. Compare the 35 mA gate trigger requirement against available drive circuit capabilities. Evaluate the thermal resistance characteristics of the SMTO-263-2 package against the expected heat dissipation loads in the target application design.

Triacs Part Context

This triac belongs to the Qxx16xHx series from Littelfuse, which focuses on high-voltage thyristor solutions. The series provides standardized pinouts and electrical characteristics for designers requiring reliable AC switching components. The Q2016NH4RP variant specifically addresses the need for higher current handling compared to lower-amperage siblings while maintaining the same physical footprint.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance. Verify that any substitute part maintains the 1 kV voltage rating and compatible SMTO-263-2 package dimensions to ensure board compatibility.
