L0103DE

Triacs Overview

The Littelfuse L0103DE is a 1A sensitive bidirectional triac from the EV Series, housed in a TO-92 through-hole 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 exhibits a peak on-state voltage of 1.6 V and a maximum holding current of 7 mA. Gate trigger characteristics include a minimum gate trigger current (IGT) of 3 mA and a maximum gate trigger voltage (VGT) of 1.3 V. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Direct interface capability with microprocessor drivers
• Glass-passivated die voltage blocking junctions for long-term reliability
• RoHS compliant and halogen-free construction

Triacs Applications

• Valve controls in washing machines
• Replacement for mechanical relays requiring extended operational life
• Replacement for hybrid relays in white goods applications

Triacs Procurement Notes

Verify the specific suffix 'E' confirms the TO-92 package configuration before procurement. Confirm that the 400V rating aligns with circuit requirements. Ensure ordering quantities match available packing modes such as bulk or ammo pack. Validate compliance with RoHS standards if required by the final assembly specifications.

Triacs Selection Notes

Select this component when a 400V blocking voltage is sufficient for the application. The 3mA gate sensitivity allows for direct interfacing with low-power logic circuits. Consider thermal derating curves for continuous operation above 50°C case temperature. Verify that surge currents remain within the specified non-repetitive limits.

Triacs Part Context

This part belongs to the Littelfuse L01 EV Series of 1 Amp Sensitive Triacs. The series includes variants with different voltage ratings (400V, 600V, 800V) and gate sensitivities. The 'D' suffix indicates the 400V rating, while 'E' denotes the TO-92 package type.

Triacs Replacement Considerations

L0103MEAP serves as a higher voltage alternative with 600V blocking capability in the same TO-92 package. L0103DERP offers the same electrical specifications but utilizes tape and reel packaging instead of bulk or ammo pack formats.
