Triacs datasheet and documents for Q4006VH3TP

Q4006VH3TP

Triacs Overview

The Q4006VH3TP is a Littelfuse Alternistor TRIAC rated for 400 V repetitive peak off-state voltage and 6 A RMS on-state current. It utilizes a TO-251AA (V-Pak) through-hole package with three terminals. The device features snubberless operation, supporting a minimum critical rate of rise of off-state voltage of 50 V/µs and a minimum commutation dv/dt of 20 V/µs. Key electrical limits include a maximum DC gate trigger current of 10 mA and a maximum holding current of 15 mA.

Triacs Feature Summary

Snubberless design capability for simplified circuit implementation
High reliability construction suitable for demanding environments
Integrated thermal management via main terminal 2 connection

Triacs Applications

Solid-state relay control circuits
General purpose AC power switching applications
Industrial motor speed control systems

Triacs Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and tape-and-reel packaging configuration. Ensure the selected variant matches the required RoHS compliance standards and leaded pin availability for the target assembly process. Cross-reference the manufacturer's latest datasheet to confirm the exact marking code and date code requirements for production integration.

Triacs Selection Notes

Select this component when a robust TRIAC solution with integrated snubberless functionality is required for AC load control. The 6A RMS rating supports moderate power loads, while the 400V blocking voltage suits standard low-voltage AC distribution networks. Consider the TO-251AA package for efficient PCB space utilization and reliable thermal dissipation in high-density designs.

Triacs Part Context

This part belongs to the Littelfuse Alternistor family, which combines TRIAC functionality with internal snubberless characteristics. These devices are engineered to reduce external component count and improve system reliability by eliminating the need for traditional RC snubber networks across the main terminals.
