L0109MEAP

Triacs Overview

The L0109MEAP is a bidirectional triac from the Littelfuse L01 EV Series, designed for sensitive gate triggering applications. It features an RMS on-state current (It RMS) of 1 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum holding current (Ih) of 10 mA and a gate trigger current (Igt) of 10 mA with a gate trigger voltage (Vgt) of 1.3 V. On-state voltage is specified at 1.6 V, while leakage current remains at 5 uA under VDRM conditions. Non-repetitive peak on-state currents are rated at 10 A and 12 A. Operating temperatures range from -40 C to +125 C. The component utilizes a TO-92 through-hole package and is supplied in Ammo Pack configuration.

Triacs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate current requirements
• Robust thermal performance supporting operation across extended industrial temperature ranges
• Compact through-hole form factor suitable for space-constrained circuit board layouts

Triacs Applications

• Lighting control systems requiring precise phase-angle regulation
• Solid-state relay implementations for AC load switching
• Motor speed control circuits for small appliances

Triacs Procurement Notes

Verify the specific suffix MEAP against official Littelfuse documentation to confirm the Ammo Pack packaging variant. Ensure compatibility with existing PCB footprints for the TO-92 case style. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 1 A RMS current rating and 400 V blocking voltage are required for AC power control. The sensitive gate characteristic makes it suitable for microcontroller-driven interfaces where minimal drive current is available. Confirm that the TO-92 package meets mechanical constraints and that the 125 C maximum junction temperature aligns with system thermal design goals.
