Q2008DH4RP

Triacs Overview

The Q2008DH4RP is a Littelfuse Alternistor triac rated for 200 V repetitive peak off-state voltage and 8 A RMS on-state current. It features a TO-252-3 surface mount package with a maximum operating temperature of +125 °C. Key electrical parameters include a non-repetitive peak on-state current of 83 A or 100 A, an on-state voltage of 1.6 V, and a holding current maximum of 35 mA. The device requires a gate trigger voltage of 1.3 V and a gate trigger current of 35 mA, with an off-state leakage current of 10 uA at VDRM.

Triacs Feature Summary

• Snubberless operation capability for simplified circuit design
• High surge current handling for robust performance
• Surface mount construction for automated assembly

Triacs Applications

• Lighting control systems
• Motor speed regulation
• Heating control circuits

Triacs Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm availability status. Note that this component may be classified as obsolete in certain distributor catalogs. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement plans.

Triacs Selection Notes

Select this component when a low-voltage, high-current surface mount triac is required. The 200 V rating suits lower voltage AC applications. Consider the TO-252-3 package size for space-constrained designs. Verify that the 8 A RMS current capacity meets the load requirements without excessive derating.

Triacs Part Context

This device belongs to the Littelfuse Qxx08xHx series of Alternistors. These components are designed as snubberless triacs, offering improved reliability compared to standard triacs by reducing external component count. The series provides various voltage ratings while maintaining consistent current and package characteristics.

Triacs Replacement Considerations

Q2008DH4RP is listed as obsolete. Check Littelfuse documentation for direct replacements within the same series or consult distributors for equivalent snubberless triacs with matching 200V/8A specifications.
