Overview
The EC103D1,412 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 exhibits a low gate trigger current of 12 uA, enabling ultra-sensitive triggering capabilities. It operates within a junction temperature range from -40 C to +110 C and utilizes a TO-92 through-hole package.
Feature Summary
- Ultra-sensitive gate structure for reliable triggering with minimal control current
- Planar passivated construction ensuring high reliability under various conditions
- Robust surge current handling capability for transient protection applications
Applications
- Lighting control circuits requiring sensitive gate drive
- Battery charger management systems
- Over-voltage protection devices in power supplies
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure the component matches the required thermal and voltage ratings for the target application environment before finalizing procurement specifications.
Selection Notes
Select this component when a compact through-hole SCR with low gate sensitivity is required. Compare its 800 mA RMS rating and 400 V blocking voltage against circuit demands. Consider the TO-92 package constraints for PCB layout and thermal dissipation requirements relative to alternative surface mount options.
Part Context
This part belongs to the EC103xx series of Silicon Controlled Rectifiers designed for general-purpose switching and protection. The series emphasizes cost-effective solutions for consumer electronics and industrial control applications where space efficiency and reliable latching behavior are critical design parameters.
Replacement Considerations
Cross-reference with other 400V 800mA TO-92 SCRs from manufacturers like Littelfuse or Vishay. Verify pinout compatibility and gate trigger characteristics to ensure functional equivalence without redesigning the driving circuitry.
