QJ6006DH4RP

Triacs Overview

The Littelfuse QJ6006DH4RP is a bidirectional triac (Alternistor) designed for surface-mount applications. It features an RMS on-state current of 8 A and a rated repetitive peak off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum on-state voltage of 1.5 V, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The leakage current in the off-state is specified at 10 µA under VDRM conditions. It is housed in a TO-252-3 package.

Triacs Feature Summary

• High thermal stability with a maximum operating temperature of 150°C
• Surface-mount construction in a compact TO-252-3 package
• Low gate trigger current for efficient microprocessor interfacing

Triacs Applications

• Solid-state relay circuits
• AC motor speed control systems
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix 'H4RP' against the manufacturer's official datasheet to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure the ordering quantity aligns with the standard factory reel size of 2500 units or cut-tape availability. Cross-reference the part number with Littelfuse documentation to validate the exact pinout and thermal characteristics for your PCB layout.

Triacs Selection Notes

Select this component when a high-temperature capable triac is required for SMD designs. The 600V rating suits general AC line applications, while the 8A RMS current supports moderate load switching. Compare the 1.5V on-state voltage against alternatives to minimize conduction losses. Verify that the 35mA gate drive capability matches the output strength of the control circuitry.

Triacs Part Context

This part belongs to the Littelfuse QJxx08xH series of Alternistor TRIACs. These devices are engineered for high reliability in power control applications. The series utilizes advanced silicon technology to provide robust performance in compact surface-mount packages, distinguishing them from through-hole equivalents like the QJ6006LH4TP.

Triacs Replacement Considerations

Direct substitutes include the QJ6008DH4RP (800V rating) and Q8008DH4RP (800V rating). For lower current requirements, the Q6006DH4RP offers similar functionality but with a 6A RMS rating. Verify voltage derating if replacing with higher-voltage variants.
