Q2008VH4TP

Triacs Overview

The Littelfuse Q2008VH4TP is an Alternistor TRIAC designed for high-temperature applications. It features a rated repetitive off-state voltage (VDRM) of 200 V and an on-state RMS current (ITRMS) of 8 A. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a gate trigger voltage (VGT) of 1.3 V and a gate trigger current (IGT) of 35 mA. It utilizes a TO-251AA-3 through-hole package, ensuring reliable performance in power control circuits requiring robust thermal management.

Triacs Feature Summary

• High-temperature capability with operation up to 125°C
• Alternistor technology for improved switching characteristics
• Through-hole mounting for secure mechanical installation

Triacs Applications

• Industrial motor control systems
• Solid-state relay modules
• Power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against official Littelfuse documentation to confirm pinout and thermal specifications. Ensure that the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components. Confirm that the TO-251AA-3 package dimensions match the target PCB footprint requirements before finalizing orders.

Triacs Selection Notes

Select this component when a 200 V blocking voltage and 8 A continuous current are required in a through-hole configuration. The Alternistor design offers advantages over standard TRIACs in terms of dv/dt immunity. Consider the maximum operating temperature of 125°C for thermal budgeting. This part is suitable for applications where moderate voltage ratings and high current handling are necessary in compact industrial enclosures.

Triacs Part Context

This device belongs to the Littelfuse Alternistor family, which integrates TRIAC functionality with enhanced switching speed and noise immunity. The Q2008 series specifically targets low-voltage, high-current applications. The TO-251AA-3 package provides a balance between thermal dissipation and board space efficiency compared to larger through-hole packages.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for direct equivalents. Verify that any alternative part matches the 200 V VDRM, 8 A ITRMS, and TO-251AA-3 package constraints. Ensure compatibility with existing gate drive circuitry regarding VGT and IGT specifications.
