Overview
The EL817(C)-F is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features a DIP-4 through-hole package with an isolation voltage of 5000Vrms. The device comprises an infrared emitting diode and an NPN phototransistor. Key electrical parameters include a collector-emitter voltage of 35V, a maximum collector current of 50mA, and a forward current of 20mA. The typical forward voltage is 1.4V. The Current Transfer Ratio (CTR) ranges from 200% to 400%. Operating temperature spans -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical transmission.
- Features a standard four-pin DIP package suitable for through-hole mounting.
- Utilizes an NPN phototransistor output for digital signal switching applications.
Applications
- Industrial control systems for signal isolation
- Power supply feedback loops
- Communication equipment interface isolation
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm pinout compatibility and insulation class. Ensure the procurement source provides valid UL certification records if required for end-product safety approvals. Confirm package dimensions match the target PCB footprint before ordering.
Selection Notes
Select this component when a robust, low-cost transistor output isolator is required for general-purpose digital signaling. Consider the CTR range and operating temperature limits relative to the application environment. Verify that the 50mA collector current rating meets the load requirements of the downstream circuitry.
Part Context
This part belongs to the widely used 817 series of optocouplers, known for their reliability in basic isolation tasks. The EL817 variant specifically denotes the transistor output configuration within Everlight's portfolio. It serves as a common replacement for other generic 817-type components in legacy designs.
Replacement Considerations
Compatible substitutes include PC817 and IL817 variants, provided they share the same DIP-4 package and electrical characteristics. Verify that alternative manufacturers meet the same isolation voltage and CTR specifications.
