LX807DEAP

Triacs Overview

The Littelfuse LX807DEAP is a logic-level sensitive gate triac designed for AC switching applications. It features an RMS on-state current of 800 mA and a non-repetitive peak on-state current of 8 A. The device supports a rated repetitive off-state voltage (VDRM) of 400 V with a maximum off-state leakage current of 5 uA at VDRM. Key electrical parameters include an on-state voltage of 1.6 V, a maximum holding current of 5 mA, and a gate trigger voltage of 1.3 V. Gate trigger currents are specified at 5 mA and 7 mA. The component operates within a temperature range of -40°C to +110°C and is housed in a TO-92 through-hole package.

Triacs Feature Summary

• Sensitive gate architecture enables reliable triggering with low gate drive requirements.
• Logic-level compatibility allows direct interfacing with standard digital control circuits.
• Glass-passivated junctions ensure long-term parameter stability and device reliability.

Triacs Applications

• AC power switching and phase control circuits
• Solid state relay implementations
• Lighting control systems

Triacs Procurement Notes

Verify the specific suffix DEAP against the manufacturer's official datasheet to confirm the exact packaging configuration and regional compliance markings. Ensure that the ordering documentation matches the required lead time and factory production schedule provided by authorized distributors. Cross-reference the part number with Littelfuse's current product status to confirm availability and obsolescence warnings before finalizing procurement plans.

Triacs Selection Notes

Select this component when a compact through-hole solution is required for low-power AC load control. The 800 mA RMS rating suits small appliances and lighting dimmers. Verify that the 400 V blocking voltage meets the circuit's peak line voltage requirements. Consider the TO-92 package constraints for thermal management and PCB layout space compared to higher-current alternatives.

Triacs Part Context

This device belongs to the LX8 series of triacs from Littelfuse, which focuses on sensitive gate technologies for efficient AC control. The LX807DEAP variant specifically utilizes the DEAP suffix to denote its through-hole TO-92 packaging and ammo pack distribution format. This series is engineered for cost-effective integration in consumer electronics and industrial control modules requiring reliable bidirectional switching.

Triacs Replacement Considerations

The LX807DTRP serves as a surface-mount alternative within the same family, offering identical electrical characteristics but in an SOT-223-4 package. Designers must account for significant differences in thermal dissipation capabilities and physical footprint when substituting between these form factors.
