Overview
The Littelfuse EC103B is a sensitive silicon-controlled rectifier (SCR) with a 0.8 A on-state current rating and a 200 V repetitive peak off-state voltage. It features a DC gate trigger current of 200 µA, a maximum holding current of 5 mA, and a peak on-state voltage of 1.7 V. The device operates within a junction temperature range of -65 °C to +110 °C and utilizes a glass-passivated chip for parameter stability.
Feature Summary
- Half-wave unidirectional gate-controlled rectifier
- Glass-passivated junction for reliability
- Sensitive gate triggering capability
Applications
- Lighting control circuits
- Motor speed regulation
- Temperature control systems
Procurement Notes
Verify the specific package type and lead configuration against the official Littelfuse datasheet before ordering. Confirm that the 200 V blocking voltage and 200 µA gate sensitivity meet the circuit requirements. Ensure compliance with RoHS standards if required by the application specifications.
Selection Notes
Select this component when a low-power SCR with moderate voltage blocking is needed. The 200 µA gate sensitivity allows for direct interfacing with logic-level signals without excessive drive current. Consider thermal derating curves for high ambient temperatures or continuous conduction angles below 180 degrees.
Part Context
This part belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. The product family includes devices ranging from 0.8 A to 10 A with voltage ratings up to 600 V. These components are designed to complement power SCRs in applications requiring precise gate control.
Replacement Considerations
The 2N5064 is a JEDEC-registered equivalent within the same catalog offering identical electrical characteristics and pinout compatibility for direct substitution in existing designs.
FAQ
What is the maximum operating junction temperature for the EC103B?
The maximum operating junction temperature is +110 °C.
How does the gate trigger current affect turn-on time?
Higher gate trigger currents reduce the turn-on time; typical values decrease as IGT increases from 50 µA to 500 µA.
Is the EC103B electrically isolated?
No, the EC103B is a non-isolated device. Electrical isolation is available only in specific TO-220 packages with designated suffixes.
