Q4006N4RP

Triacs Overview

The Littelfuse Q4006N4RP is a bidirectional triac designed for power control applications. It features an RMS on-state current of 6 A and a rated repetitive peak off-state voltage of 400 V. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. Non-repetitive peak on-state currents are specified at 65 A and 80 A. The component exhibits an on-state voltage of 1.6 V and a maximum off-state leakage current of 50 uA under rated voltage conditions. It is housed in an SMTO-263-2 surface-mount package.

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure compliance with RoHS and REACH requirements as documented in the product specifications. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Triacs Selection Notes

Select this component based on the required 400 V blocking voltage and 6 A continuous current rating. Evaluate the gate trigger characteristics to ensure compatibility with the driving circuitry. Confirm that the SMTO-263-2 package dimensions fit the target PCB layout and thermal management strategy.

Triacs Part Context

This triac belongs to the Qxx06xx series from Littelfuse, which provides standardized power control solutions. The Q4006N4RP variant specifically utilizes the N4 suffix to denote its package style and terminal configuration within the broader family of 6 A triacs.

Triacs Replacement Considerations

Direct substitutes may include other 6 A, 400 V triacs in similar SMD packages. Verify equivalent electrical ratings and pin assignments before substitution.
