Overview
The EL817(S)(D)(TB)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a minimum collector-emitter breakdown voltage of 35 V, a maximum forward current of 50 mA, and a typical current transfer ratio ranging from 300% to 600% at a forward current of 5 mA and collector-emitter voltage of 5 V. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- High isolation voltage capability of 5000 Vrms for safe circuit separation
- Compact surface-mount SMD-4 package design suitable for automated assembly
- Wide operating temperature range extending up to +110°C
- RoHS compliant construction with lead-free terminals
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
- Switching power supply regulation
Procurement Notes
Verify the specific suffix configuration against the manufacturer datasheet to ensure correct pinout and packaging type. Confirm RoHS compliance status and approval numbers such as UL or VDE if required for end-product certification. Check availability status as distribution channels may vary. Ensure the selected variant matches the required current transfer ratio specifications for the intended application circuit design.
Selection Notes
Select this component when a surface-mount solution is required for galvanic isolation. Compare the current transfer ratio requirements against the specified minimum values to ensure adequate signal transmission. Verify that the 35 V collector-emitter voltage rating exceeds the maximum load voltage in the output circuit. Consider the thermal management requirements given the wide operating temperature range and surface-mount thermal characteristics.
Part Context
This part belongs to the EL817 series of photocouplers, which are widely used for electrical isolation. The series includes various package options such as DIP and SMD configurations. The EL817(S)(D)(TB)-G specifically denotes the surface-mount variant with tape and reel packaging. This series is recognized for its reliability in providing isolation between low-voltage control circuits and higher-voltage power stages.
Replacement Considerations
Direct replacements must match the SMD-4 package, 5000 Vrms isolation, and NPN phototransistor output. Verify equivalent current transfer ratios and voltage ratings. Cross-reference with other manufacturers' EL817-compatible parts ensuring identical pinout and mechanical dimensions for board compatibility.
