Triacs datasheet and documents for Q6006VH4

Q6006VH4

Triacs Overview

The Q6006VH4 is a 6A Alternistor TRIAC rated for 600V blocking voltage. It features a TO-251AA (DPAK) surface-mount package with an isolated case connection to Terminal 2. Key electrical parameters include a maximum DC gate trigger current of 35 mA, a maximum DC gate trigger voltage of 1.5 V, and a holding current of 35 mA. The device supports a minimum commutation turn-off dv/dt of 20 V/µs and a minimum non-repetitive off-state voltage rate of rise of 425 V/µs.

Triacs Feature Summary

Alternistor technology provides snubberless operation for high commutation performance
Isolated case connection allows direct mounting to heatsinks without additional insulation
Sensitive gate design facilitates easy triggering with low power control circuits

Triacs Applications

AC motor speed control systems
Temperature modulation and heating control
Solid-state relay switching applications

Triacs Procurement Notes

Verify the specific suffix 'H4' against the manufacturer's current product status, as this variant may be obsolete or superseded by newer revisions within the Q6006 series. Confirm that the TO-251AA package dimensions match the target PCB footprint requirements. Ensure the 600V rating aligns with the peak line voltages present in the intended circuit design to maintain adequate safety margins.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with high commutation capability is required for AC phase control. The 6A RMS current rating suits moderate power loads. Consider the TO-251AA package for automated assembly processes. Verify that the 35 mA gate sensitivity meets the drive capabilities of the microcontroller or optocoupler interface used in the application.
