QJ6006VH3TP

Triacs Overview

The QJ6006VH3TP is a high-temperature Alternistor TRIAC manufactured by Littelfuse Inc., designed for robust AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 6 A. The device utilizes a TO-251AA (IPAK) through-hole package, providing reliable thermal management. Key electrical parameters include a gate trigger voltage (Vgt) of 1.3 V and a gate trigger current (Igt) of 35 mA. It operates within a junction temperature range of -40 °C to +150 °C, ensuring stability in demanding environments.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• High-temperature operation up to 150 °C junction temperature
• Alternistor technology for improved commutation performance

Triacs Applications

• Solid-state relay modules
• Motor speed control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix 'H' indicates high-temperature rating and 'TP' denotes tape-and-reel packaging if applicable, though datasheets may list tube packaging. Confirm RoHS compliance status with the manufacturer's latest documentation. Ensure the TO-251AA footprint matches the target PCB layout. Cross-reference the exact part number against Littelfuse official databases to avoid confusion with similar series variants like Q6006VH3TP.

Triacs Selection Notes

Select this component when a 600 V, 6 A TRIAC is required for high-temperature environments. The snubberless feature reduces external component count compared to standard TRIACs. Consider the TO-251AA package size for space-constrained designs requiring through-hole mounting. Verify that the 35 mA gate trigger current aligns with the driving circuit's output capabilities.

Triacs Part Context

This part belongs to Littelfuse's Alternistor family, which combines TRIAC functionality with enhanced switching characteristics. The QJ prefix often denotes specific manufacturing or packaging variations within the broader Q-series. It serves as a replacement for older generation TRIACs in industrial and consumer appliances where reliability and thermal performance are critical.

Triacs Replacement Considerations

Direct substitutes may include other 600 V, 6 A TRIACs in TO-251AA packages from Littelfuse or competitors, provided they meet the 150 °C operating temperature and snubberless requirements. Verify pinout compatibility and thermal resistance values before substitution.
