Overview
The EL3H7(J)(EB)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a current transfer ratio of 100-200% CTR. The device provides a high isolation voltage of 3750 Vrms and supports a maximum forward current of 50 mA. It operates within a temperature range of -55°C to +110°C and is housed in a surface-mount package.
Feature Summary
- High insulation voltage capability for reliable signal isolation
- Wide operating temperature range suitable for demanding environments
- NPN phototransistor output configuration
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between circuits with different ground potentials
- Power supply feedback loops
Procurement Notes
Verify the specific suffix (J)(EB) against the manufacturer datasheet to confirm the Current Transfer Ratio binning and packaging type. Ensure the component status is active, as some variants in this series may be discontinued. Cross-reference the pinout and mechanical dimensions with the official footprint data before integration.
Selection Notes
Select this component when a moderate speed response and high isolation voltage are required. The NPN output is suitable for sinking current applications. Compare the CTR specifications against other models in the EL3H7 series to ensure compatibility with the target circuit's drive requirements and noise immunity standards.
Part Context
This part belongs to the EL3H7-G series of transistor output optocouplers from Everlight. The series offers various CTR bins and packaging options. The EL3H7(J)(EB)-G specifically denotes a particular CTR range and reel/cut-tape packaging configuration within this family of surface-mount isolation devices.
Replacement Considerations
Direct substitutes include other EL3H7 variants with matching CTR ranges, such as EL3H7(E)(EB)-G or EL3H7(A)(EB)-G, provided the CTR specifications align with the design requirements. Verify pin compatibility and thermal characteristics before substitution.
