Q8006R5

Triacs Overview

The Littelfuse Q8006R5 is a bidirectional triac from the Teccor Qxx10xx series, designed for AC switching and phase control applications. It features an RMS on-state current of 6 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. 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 50 mA to 75 mA. The on-state voltage is specified at 1.6 V, with non-repetitive peak currents of 65 A and 80 A.

Triacs Feature Summary

• Integrated glass-passivated junctions ensure long-term parameter stability and device reliability.
• Bidirectional AC switching capability allows gate control for either polarity of main terminal voltage.
• High thermal tolerance supports operation in demanding industrial environments up to 125°C.

Triacs Applications

• AC motor speed controls
• Temperature modulation systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number with official Littelfuse documentation. Confirm that the specific suffix matches the required pinout and isolation specifications. Ensure compliance with RoHS directives if applicable to the target assembly. Validate supplier authorization status before procurement to mitigate counterfeit risks.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 6 A continuous current rating are required for AC load control. The TO-220-2 package facilitates efficient heat dissipation compared to smaller surface-mount alternatives. Verify that the gate trigger requirements align with the driving circuit's output capabilities.

Triacs Part Context

This triac belongs to the Teccor Qxx10xx family, which provides robust solutions for general-purpose AC power control. The series is characterized by high surge current handling and stable latching characteristics suitable for resistive and inductive loads.

Triacs Replacement Considerations

Direct substitutes may include other 800 V, 6 A triacs in TO-220 packages from the same manufacturer, such as the Q8006N5TP, provided the mounting style and pin configuration are compatible with the existing design.
