Triacs datasheet and documents for QJ4016NH2RP
Triacs Overview
The QJ4016NH2RP is a bidirectional triac manufactured by Littelfuse, 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 gate trigger current (Igt) of 35 mA, a holding current (Ih) maximum of 50 mA, and an on-state voltage of 1.6 V. Non-repetitive on-state currents are specified at 167 A and 200 A under different conditions.
Triacs Feature Summary
- Bidirectional AC switch with integrated gate control for either polarity of main terminal voltage
- Glass-passivated junctions ensure long-term device reliability and parameter stability
- Surface-mount construction in an SMTO-263-2 package for automated assembly
Triacs Applications
- AC speed controls
- Temperature modulation controls
- Lighting controls requiring noise immunity
Triacs Procurement Notes
Verify the specific suffix 'H2' against official Littelfuse documentation to confirm exact pinout and thermal characteristics, as variations exist within the Qxx16xHx series. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.
Triacs Selection Notes
Select this component when a 16 A RMS current rating and 400 V blocking voltage are required for AC phase control. The SMTO-263-2 package is suitable for surface-mount designs where space efficiency is prioritized. Verify that the 35 mA gate trigger current matches the driving circuit capabilities and that the operating temperature range meets the environmental requirements of the target application.
Triacs Part Context
This part belongs to the QJxx16xHx series of triacs from Littelfuse. This series is characterized by high current capacity and robust construction for industrial and consumer AC power control. The QJ4016NH2RP specifically addresses applications needing reliable switching in compact surface-mount form factors while maintaining high voltage tolerance.
Triacs Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic triac replacements may differ in gate sensitivity or thermal resistance. Do not assume interchangeability without verifying pinout compatibility and absolute maximum ratings.
