EC103D1WX

Overview

The EC103D1WX is a Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 800 mA. The device utilizes sensitive gate triggering with a maximum gate trigger current of 12 uA and a gate trigger voltage of 800 mV. It operates within a temperature range of -40°C to +110°C and is housed in a TO-92 plastic package.

Feature Summary

• Sensitive gate control for low-power triggering applications
• Robust thermal performance across extended industrial temperature ranges
• Compact through-hole mounting configuration

Applications

• Lighting control circuits
• Motor speed regulation systems
• General purpose switching applications

Procurement Notes

Verify the manufacturer designation, as Littelfuse also produces the EC103D1 variant. Confirm the specific suffix WX corresponds to the intended packaging or tape-and-reel format if required. Ensure component authenticity through authorized supply channels to guarantee electrical parameter compliance.

Selection Notes

Select this component when a compact SCR with high sensitivity is required for low-current gate drive scenarios. The 400 V rating suits low-voltage AC/DC switching tasks. Verify that the TO-92 package fits the mechanical constraints and that the 800 mA current capacity meets the load requirements.

Part Context

This part belongs to the EC103xx series of silicon controlled rectifiers. These devices are designed for general-purpose switching and phase control applications. The series offers various voltage ratings and current capacities within standardized packages to support diverse electronic design needs.

Replacement Considerations

Cross-reference with other manufacturers' 400V 800mA SCRs in TO-92 packages. Verify gate sensitivity parameters match the driving circuit capabilities before substitution.
