Triacs datasheet and documents for QK016NH4TP
Triacs Overview
The Littelfuse QK016NH4TP is a bidirectional triac designed for surface mount applications. It features an RMS on-state current of 16 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 gate trigger voltage of 2 V. The on-state voltage is specified at 1.6 V, with a maximum off-state leakage current of 5 uA under VDRM conditions.
Triacs Feature Summary
- High-voltage blocking capability suitable for demanding AC power control environments
- Surface mount construction in a compact SMTO-263-2 package for automated assembly
- Defined gate sensitivity characteristics for reliable triggering in control circuits
Triacs Applications
- AC motor speed control systems
- Solid state relay output stages
- Industrial heating element regulation
Triacs Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm exact gate trigger specifications. Ensure the ordering quantity aligns with the factory packaging requirements. Confirm RoHS compliance status through official documentation before finalizing procurement orders.
Triacs Selection Notes
Select this component when a 1 kV rating and 16 A continuous current are required in a surface mount form factor. Compare gate trigger currents with alternative packages if PCB space allows. Verify thermal management capabilities match the application's heat dissipation needs.
Triacs Part Context
This part belongs to the Qxx16xHx series of thyristors from Littelfuse. The series provides various options for gate sensitivity and voltage ratings within the same physical footprint. This specific model offers a standardized configuration for general-purpose high-voltage switching.
Triacs Replacement Considerations
Check for other suffixes in the QK016NH series which may offer different gate trigger currents while maintaining identical voltage and current ratings. Verify pinout compatibility before substituting with components from other manufacturers.
