Q2008DH3TP

Triacs Overview

The Q2008DH3TP is a surface-mount Alternistor triac from Littelfuse, housed in a TO-252-3 package. It features a rated repetitive off-state voltage of 200 V and an on-state RMS current of 8 A. The device exhibits a maximum holding current of 15 mA and an on-state voltage of 1.6 V. Gate trigger parameters include a peak reverse voltage of 1.3 V, with an operating temperature range spanning from -40°C to +125°C.

Triacs Feature Summary

• High surge capability for robust circuit protection
• Sensitive gate triggering for efficient control
• Surface mount construction for automated assembly

Triacs Applications

• Solid state relay load switching
• AC motor speed control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific datasheet version and component marking against official Littelfuse documentation before integration. Confirm that the TO-252-3 footprint matches the target PCB layout requirements. Ensure thermal management strategies align with the specified junction temperature limits during high-current operation.

Triacs Selection Notes

Select this component when a compact, surface-mount solution is required for low-voltage AC switching applications. The 8 A RMS rating suits moderate power loads, while the 200 V blocking voltage defines its suitability for lower voltage AC systems compared to higher-rated counterparts.

Triacs Part Context

This part belongs to the ALTERNISTOR family of thyristors designed for sensitive gate triggering and high surge handling. It serves as a solid-state alternative to mechanical relays in AC power control scenarios, offering faster switching speeds and longer operational life within Littelfuse's discrete semiconductor portfolio.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Cross-reference electrical ratings such as VDRM and IT(RMS) to ensure compatibility with existing circuit designs.
