Overview
The EL817(S1)(C)(TD)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 35 V, maximum forward current of 60 mA, and maximum collector current of 50 mA. The current transfer ratio ranges from 200% to 400% at a forward current of 5 mA. It operates within a temperature range of -55 °C to +110 °C.
Feature Summary
- High isolation voltage capability between input and output for circuit protection
- Compact surface-mount design suitable for automated assembly
- Wide operating temperature range for diverse environmental conditions
Applications
- Signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix (TD) against the manufacturer's datasheet to confirm the exact tape-and-reel packaging configuration and pinout orientation. Ensure compliance with RoHS directives as indicated by the product designation. Cross-reference the part number with official Everlight documentation to validate availability status and lead times prior to procurement.
Selection Notes
Select this component when surface-mount technology is required for the EL817 form factor. Confirm that the 5000 Vrms isolation rating meets the safety standards of the target application. Verify that the 50 mA collector current capacity is sufficient for the load driven by the phototransistor output stage.
Part Context
This part belongs to the EL817 series, a widely used family of optocouplers known for their reliability in isolating low-voltage digital signals from higher-voltage analog or power circuits. The series offers both through-hole and surface-mount variants, with the S1 suffix typically denoting specific mechanical dimensions or lead configurations within the SMD category.
Replacement Considerations
Compatible substitutes include other EL817 series surface-mount variants such as EL817(S)(C)(TU)-V, provided the mechanical footprint and electrical characteristics match the design requirements.
