Overview
The Littelfuse EC103M1AP is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting in TO-92 packages. It features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 800 mA. The device utilizes a sensitive gate structure with a maximum gate trigger current of 12 µA, enabling reliable triggering from low-power control circuits. Key electrical characteristics include a holding current of 5 mA and a critical rate of rise of on-state current (di/dt) of 50 A/µs at 60 Hz.
Feature Summary
- Sensitive gate architecture allows triggering with minimal gate current
- Robust thermal performance with operating temperatures up to 300°C junction
- Through-hole TO-92 package facilitates easy circuit board integration
Applications
- Lighting control systems requiring low-power triggering
- Battery charger circuits for AC-to-DC conversion
- General-purpose power switching applications
Procurement Notes
Verify the specific suffix 'AP' against official Littelfuse documentation to confirm availability and exact pinout configuration. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the DO-204AH or TO-92 lead form requirements with your PCB footprint specifications before ordering to prevent assembly mismatches.
Selection Notes
Select this component when a high-voltage SCR with low gate sensitivity is required for controlling loads up to 800 mA. The 600 V rating suits standard AC line applications. Consider the 12 µA gate trigger current for compatibility with microcontroller outputs or high-impedance sensors. Evaluate the TO-92 package size constraints against available board space.
Part Context
This part belongs to the EC103xx series of sensitive gate SCRs manufactured by Littelfuse. The series offers various voltage and current ratings within the same package family, allowing designers to scale power handling capabilities while maintaining consistent gate drive requirements and mechanical form factors across different product lines.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source data. Verify compatibility with generic equivalents by matching the 600 V blocking voltage, 800 mA current rating, and TO-92 package dimensions.
