Triacs datasheet and documents for L0109DE

L0109DE

Triacs Overview

The Littelfuse L0109DE is a 1A sensitive bidirectional triac from the EV Series, housed in a TO-92 package. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 1 A. The device requires a maximum gate trigger current (IGT) of 10 mA across all quadrants and has a peak on-state voltage (VTM) of 1.6 V. It operates within a junction temperature range of -40°C to +125°C and offers a non-repetitive surge peak on-state current (ITSM) of 10 A at 50 Hz or 12 A at 60 Hz.

Triacs Feature Summary

Direct interface capability with microprocessor drivers
Glass-passivated die voltage blocking junctions for parametric stability
RoHS compliant and halogen-free construction

Triacs Applications

Valve controls in washing machines
Replacement for mechanical relays requiring long life
Replacement for hybrid relays requiring long life

Triacs Procurement Notes

Verify the specific suffix 'E' confirms the TO-92 through-hole package configuration. Confirm that the 'D' designation aligns with the required 400 V blocking voltage rating for the target circuit design. Ensure ordering quantities match available bulk or ammo pack configurations as specified by the manufacturer.

Triacs Selection Notes

Select this component when a 1 A RMS current rating and 400 V blocking voltage are sufficient for the load. The 10 mA gate sensitivity allows direct driving from standard logic outputs without additional amplification. Verify thermal management requirements against the 100°C/W junction-to-ambient resistance for the TO-92 package under continuous operation.

Triacs Part Context

This part belongs to the L01 EV Series of 1 Amp Sensitive Triacs. The series includes variants with different voltage ratings (400 V, 600 V, 800 V) and gate sensitivities (3 mA, 5 mA, 7 mA, 10 mA). The L0109DE specifically combines the highest gate sensitivity in the 1 A class with the lowest voltage rating in the TO-92 form factor.
