Triacs datasheet and documents for L401E8AP
Triacs Overview
The Littelfuse L401E8AP is a logic-level, sensitive-gate TRIAC designed for AC power control applications. It features a 400 V rated repetitive off-state voltage and supports an RMS on-state current of 1 A. The device operates within a temperature range of -65 °C to +110 °C. Key electrical parameters include a gate trigger current of 10 mA, a holding current of 10 mA, and an on-state voltage of 1.6 V. It utilizes a TO-92 through-hole package.
Triacs Feature Summary
- Logic-level sensitive gate design for direct microcontroller interfacing
- High thermal stability across extended operating temperatures
- Low gate trigger current for efficient drive circuitry
Triacs Applications
- AC power switching for resistive loads
- Solid state relay modules
- Lighting dimmer circuits
Triacs Procurement Notes
Verify the specific suffix 'E8AP' against official Littelfuse documentation to confirm pinout and sensitivity class. Ensure the procurement source provides valid RoHS compliance data. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards. Confirm the package type matches the required PCB footprint.
Triacs Selection Notes
Select this component when low-power gate drive is required from digital logic sources. The 400V rating suits low-voltage AC mains applications. Consider the TO-92 package constraints for thermal dissipation in high-current scenarios. Verify that the 1A RMS current meets the load requirements without excessive derating.
Triacs Part Context
This part belongs to the Lx01Ex series of thyristors manufactured by Littelfuse under the TECCOR brand. It is categorized as a sensitive-gate TRIAC within the broader family of AC power control devices. The series is designed for general-purpose switching applications requiring reliable performance in consumer electronics.
