LX803DEAP

Triacs Overview

The Littelfuse LX803DEAP is a bidirectional triac from the LX8 series, designed for sensitive gate triggering 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 holding current of 5 mA. Gate trigger specifications include a voltage of 1.3 V and currents ranging from 3 mA to 5 mA. It 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 enabling low-power control logic integration
• Robust thermal performance across extended industrial temperature ranges
• Compact through-hole form factor suitable for space-constrained PCB layouts

Triacs Applications

• Lighting control systems requiring low-current switching
• Solid-state relay inputs for AC load management
• Motor speed control circuits for small appliances

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Littelfuse documentation. Confirm RoHS compliance status through the specific datasheet revision. Ensure ordering quantities align with standard factory packaging configurations to maintain supply chain consistency.

Triacs Selection Notes

Select this component when circuit design requires a 400 V blocking voltage with 800 mA continuous current handling. The sensitive gate characteristic makes it suitable for direct interface with microcontrollers or logic gates without additional drive circuitry. Validate thermal dissipation requirements against the TO-92 package limitations for the intended ambient conditions.

Triacs Part Context

This triac belongs to the LX8 series, which focuses on low-current applications. The DEAP suffix typically denotes specific packaging or tape-and-reel configuration variations within the manufacturer's catalog. It serves as a specialized alternative to higher-current triacs in low-power AC switching scenarios.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic triac replacements may differ in gate sensitivity or holding current characteristics. Verify pinout compatibility and thermal resistance values before implementing any substitute components.
