QJ6008DH4RP

Triacs Overview

The Littelfuse QJ6008DH4RP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current (It RMS) of 8 A and a rated repetitive peak off-state voltage (VDRM) of 600 V. The device exhibits a maximum on-state voltage of 1.5 V, with gate trigger voltage (Vgt) at 1.3 V and gate trigger current (Igt) at 35 mA. Leakage current in the off-state is limited to 10 uA under VDRM conditions. It operates within a temperature range of -40 C to +150 C and is housed in a TO-252-3 surface-mount package.

Triacs Feature Summary

• High thermal stability supporting operation up to +150 C
• Low on-state voltage for improved efficiency
• Robust gate triggering characteristics for reliable switching

Triacs Applications

• AC motor speed controls
• Solid-state relays
• Lighting dimmers

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Ensure ordering suffixes match required packaging formats such as reel or cut tape specifications before finalizing procurement orders.

Triacs Selection Notes

Select this component when high junction temperature capability is required due to its +150 C rating compared to standard +125 C alternatives. Ensure circuit design accommodates the specific gate trigger current of 35 mA. Verify that the TO-252-3 package footprint aligns with PCB layout constraints for surface-mount assembly processes.

Triacs Part Context

This part belongs to the QJxx08xH series from Littelfuse's Teccor brand portfolio. It represents a specialized variant optimized for higher thermal performance compared to standard Q6008 models which typically max out at +125 C. The 'J' designation indicates specific electrical characteristics distinct from other family members like the Q6008NH4RP.

Triacs Replacement Considerations

The Q6008DH4TP serves as a tube-packaged alternative within the same electrical family but shares similar thermal limits. Direct substitution requires verifying package compatibility and ensuring the application does not strictly require the extended +150 C operating range unique to the QJ series.
