Q2008DH4TP

Triacs Overview

The Littelfuse Q2008DH4TP is a bidirectional triac (Alternistor) rated for 200 V repetitive off-state voltage and 8 A RMS on-state current. It features a non-repetitive on-state current of 80 A or 85 A, an on-state voltage of 1.6 V, and a maximum holding current of 35 mA. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-252-3 surface mount package.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• High reliability construction with flange-mountable options in the series
• Surface mount packaging for automated assembly processes

Triacs Applications

• Lighting control systems
• Motor speed regulation
• General purpose AC power switching

Triacs Procurement Notes

Verify component authenticity through authorized distributors. Confirm datasheet version matches manufacturing date codes. Ensure storage conditions comply with moisture sensitivity levels. Validate RoHS compliance status prior to integration into regulated assemblies.

Triacs Selection Notes

Select this part for low-voltage AC applications requiring robust surge handling. Compare against higher voltage variants like Q4008DH4TP if system requirements exceed 200 V. Consider thermal management needs given the 8 A continuous rating and TO-252-3 package constraints.

Triacs Part Context

Part of the Qxx08xHx series offering various voltage ratings from 200 V to 800 V. Shares common electrical characteristics such as 1.6 V on-state voltage and 35 mA gate trigger parameters across the family while differing in blocking voltage and package type.

Triacs Replacement Considerations

Q4008DH4TP offers identical current ratings but higher 400 V blocking voltage. Q6008DH4RP provides 600 V rating with slightly reduced 6 A RMS current. Verify pinout compatibility when substituting with other series members.
