Overview
The EL817(S1)(A)(TD)-G is a transistor output optocoupler manufactured by Everlight Electronics. It features a single channel with an NPN phototransistor output and DC input configuration. The device provides high isolation voltage of 5000 Vrms between the input and output circuits. It operates within a temperature range of -55°C to 110°C. The component is housed in a surface mount package designed for tape and reel processing, specifically Type I SMD format. Key electrical parameters include a minimum current transfer ratio of 50% at IF=5mA and VCE=5V, with a maximum forward current of 60 mA.
Feature Summary
- High isolation voltage capability between input and output circuits
- Surface mount package design optimized for automated assembly processes
- Halogen-free construction compliant with environmental standards
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics power supply feedback loops
- Communication equipment interface protection
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure that the ordering code matches the required surface mount variant and compliance certifications such as UL or VDE recognition before finalizing procurement orders.
Selection Notes
Select this component when surface mount technology is required for compact circuit designs. Consider the 5000 Vrms isolation rating for applications demanding robust electrical separation. Verify thermal operating limits and current transfer ratio requirements against the system's specific signal transmission needs.
Part Context
This part belongs to the EL817-G series of photocouplers from Everlight. The series includes various package options including through-hole DIP and surface mount variants. The 'S1' designation typically indicates a specific lead bend configuration for surface mounting, while '(TD)' refers to the tape and reel packaging format.
Replacement Considerations
Direct substitutes may include other EL817 series variants with compatible pinouts and electrical characteristics. Verify equivalent isolation ratings and current transfer ratios when considering alternative manufacturers or package types.
