Overview
The Littelfuse EC103M1 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for low-power triggering applications. It features a maximum repetitive off-state voltage of 600V and an RMS on-state current rating of 800mA. The device utilizes a TO-92 package with three pins, supporting through-hole mounting. Key electrical characteristics include a maximum forward voltage of 1.7V at the rated current and a typical gate trigger current of 12µA, ensuring efficient control with minimal gate drive power. The component operates within a temperature range of -40°C to 110°C.
Feature Summary
- Sensitive gate architecture enables reliable triggering with microampere-level gate currents.
- Robust 600V blocking capability suitable for medium-voltage AC switching applications.
- Compact TO-92 cylindrical plastic package facilitates easy integration into space-constrained designs.
Applications
- Light dimmer circuits
- Motor speed control systems
- Thermostat and heating control units
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical tolerances. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes prior to finalizing purchase orders.
Selection Notes
Select this component when a low-cost, high-reliability SCR is required for sensitive gate applications. The 12µA gate trigger current allows for direct interfacing with logic-level control signals without additional amplification. Consider the 800mA RMS current rating to ensure adequate headroom for the intended load requirements while maintaining thermal stability in the TO-92 package.
Part Context
The EC103M1 belongs to the EC103 series of sensitive gate SCRs manufactured by Littelfuse. This series is engineered for general-purpose AC power control where low gate drive power is essential. The part represents a standard solution for consumer electronics and industrial controls requiring robust thyristor performance in a compact form factor.
Replacement Considerations
Consult official Littelfuse cross-reference documents for verified substitutes. Generic replacements may differ in gate sensitivity or thermal characteristics. Ensure any alternative maintains compatible voltage ratings and package dimensions for direct board replacement.
