Overview
The Littelfuse EC103BRP is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting in TO-92 packages. It features a maximum repetitive off-state voltage of 200 V and an on-state RMS current rating of 800 mA. The device requires a gate trigger current of 500 µA and a gate trigger voltage of 800 mV for activation. Key electrical parameters include a maximum forward voltage of 1.7 V, a holding current of 20 A, and a leakage current of 1 µA at rated voltage. Operating temperatures range from -40°C to +125°C.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with microampere-level currents
- Robust thermal performance supporting operation across extended industrial temperature ranges
- Compact TO-92 package design facilitating efficient space utilization on printed circuit boards
Applications
- AC power control circuits requiring low-power gate drive
- Lighting dimmer applications utilizing sensitive gate SCRs
- Battery charger circuits needing precise turn-on characteristics
Procurement Notes
Verify the specific suffix 'BRP' against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Ensure the selected component matches the required voltage and current ratings for the target application. Cross-reference datasheet revisions to confirm parameter stability. Confirm RoHS compliance status directly from the manufacturer's latest release notes before finalizing procurement orders.
Selection Notes
Select this component when low gate sensitivity is critical for driving efficiency. Compare the 200 V blocking capability against peak line voltages to ensure adequate safety margins. Evaluate the 800 mA current rating against continuous load requirements. Consider the TO-92 form factor for mechanical constraints. Verify thermal dissipation capabilities under expected operating conditions to prevent overheating during sustained conduction periods.
Part Context
The EC103BRP belongs to the EC103xx series of sensitive gate SCRs manufactured by Littelfuse. This series is engineered for applications where minimal gate current is necessary for switching. The BRP designation typically indicates specific packaging or reel configuration within the broader product family. These devices complement other Littelfuse semiconductor solutions for comprehensive circuit protection and control strategies.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may lack the specific 500 µA gate sensitivity required for proper circuit function. Verify pinout compatibility and thermal characteristics before implementing any alternative components in existing designs.
