Q2006RH4

Triacs Overview

The Littelfuse Q2006RH4 is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 6 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB package style for through-hole mounting. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 25 mA or 50 mA depending on the specific variant. The on-state voltage is specified at 1.6 V, with non-repetitive peak on-state currents available in 65 A and 80 A ratings.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Glass-passivated junctions for long-term reliability and parameter stability
• Sensitive gate design allowing direct interfacing with microprocessors
• Compatible with lead-free reflow soldering processes

Triacs Applications

• Lighting control systems
• Motor speed control
• Heating control circuits
• Solid state relays

Triacs Procurement Notes

Verify the exact suffix designation when ordering, as Littelfuse part numbers often include specific packaging or tolerance codes that do not alter the core electrical function but affect logistics. Confirm RoHS compliance status directly from the manufacturer's latest documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component based on the 400 V voltage rating and 6 A current capacity requirements. Ensure the thermal management solution supports the specified operating temperature range up to 125°C. Verify that the gate drive circuitry can supply the required 25 mA trigger current reliably under all operating conditions.

Triacs Part Context

This triac belongs to the general-purpose thyristor family manufactured by Littelfuse. These devices are engineered for robust performance in industrial and consumer electronics where reliable AC switching is required. The product line emphasizes durability through glass passivation and compatibility with modern surface mount and through-hole assembly techniques.

Triacs Replacement Considerations

Direct replacements may include other 6 A, 400 V triacs in TO-220 packages from the same manufacturer or competitors, provided pinouts and electrical characteristics match. Always verify case dimensions and isolation voltage ratings to ensure mechanical fit.
