Overview
The Littelfuse EC103E2 is a Silicon Controlled Rectifier (SCR) belonging to the EC103xx series, manufactured by Littelfuse. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 800 mA. The device utilizes a TO-92 through-hole package with radial leads. Key electrical characteristics include a gate trigger current of 12 uA, a holding current maximum of 5 mA, and a forward voltage of 1.7 V. It operates within a temperature range of -40 C to +110 C.
Feature Summary
- High sensitivity gate triggering capability for efficient control circuitry
- Robust thermal performance suitable for demanding operating environments
- Compact through-hole packaging facilitating standard PCB integration
Applications
- Lighting control systems
- Motor speed regulation circuits
- General purpose switching applications
Procurement Notes
Verify the specific suffix 'E2' against official Littelfuse documentation to confirm exact pinout and tolerance specifications. Ensure the ordering part number matches the required voltage and current ratings for the target application. Cross-reference datasheets for any recent process change notifications or compliance updates before finalizing procurement.
Selection Notes
Select this component when a low gate trigger current is required for sensitive control signals. The 400 V rating makes it suitable for lower voltage AC mains applications. Consider the TO-92 package constraints regarding thermal dissipation and board space compared to surface-mount alternatives.
Part Context
This SCR is part of the broader EC103 family, which includes variants with different voltage ratings such as 100 V and 600 V. The EC103E2 specifically targets the 400 V segment, offering a balance between voltage handling and current capacity for general industrial and consumer electronics protection.
Replacement Considerations
Direct substitutes may include other 400 V, 0.8 A SCRs in TO-92 packages from manufacturers like Teccor Electronics, provided gate trigger parameters are compatible.
