Triacs datasheet and documents for Q2N4RP

Q2N4RP

Triacs Overview

The Littelfuse Q2N4RP is a standard TRIAC designed for AC power switching and phase control applications. It features a rated repetitive off-state voltage (VDRM) of 200 V and an on-state RMS current (It RMS) of 1 A. The device supports non-repetitive on-state currents of 16.7 A or 20 A, with a maximum holding current of 25 mA. Gate triggering parameters include a voltage (Vgt) of 2.5 V and current (Igt) ranging from 25 mA to 50 mA. It operates within a temperature range of -40°C to +125°C and is housed in the DO-214AB-2 surface-mount package.

Triacs Feature Summary

Designed for AC power switching and phase control applications
Surface-mount construction in a compact DO-214AB-2 package
Capable of handling 1 A RMS on-state current

Triacs Applications

Light dimmers
Motor speed controls
Heating control circuits

Triacs Procurement Notes

Verify the specific datasheet version and exact electrical tolerances against the manufacturer's official documentation before integration. Confirm that the DO-214AB-2 footprint matches the target PCB layout requirements. Ensure thermal management strategies account for the specified operating temperature range and power dissipation characteristics during continuous operation.

Triacs Selection Notes

Select this component when a low-current, surface-mount TRIAC is required for compact AC control designs. The 200 V rating suits lower voltage AC lines, while the 1 A capacity fits small loads. Consider the SMD form factor for automated assembly processes where space constraints limit through-hole options.

Triacs Part Context

This part belongs to the Littelfuse TECCOR family of TRIACs, which are widely used in consumer electronics and industrial controls. The Q2N4RP specifically targets applications requiring reliable phase-angle firing in a small outline package, providing a balance between performance and board space efficiency.

Triacs Replacement Considerations

Cross-reference with other 200 V, 1 A TRIACs in the DO-214AB-2 package. Verify pinout compatibility and thermal resistance values to ensure equivalent performance without redesigning the PCB.
