Overview
The EL3H7(D)(TB)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a maximum collector current of 50 mA and a saturation voltage of 200 mV. The device provides an isolation voltage of 3750 Vrms and operates within a temperature range of -55°C to +110°C. This specific variant offers a Current Transfer Ratio (CTR) ranging from 300% to 600% at a forward current of 5 mA, packaged in a 4-SSOP surface-mount configuration.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Wide operating temperature range suitable for harsh environments
- Robust electrical isolation for safety-critical applications
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor-based circuits
- Power supply feedback loops
Procurement Notes
Verify the exact suffix (D)(TB)-G against official Everlight documentation to ensure correct CTR binning and packaging format. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement specifications.
Selection Notes
Select this component when a high CTR range of 300-600% is required for low input current drive. Ensure the 4-SSOP package dimensions fit the PCB layout constraints. Verify that the 3750 Vrms isolation rating meets the system's safety requirements.
Part Context
This part belongs to the EL3H7-G series of transistor output optocouplers. The series is designed for general-purpose isolation applications. Variants differ primarily by CTR ranges and packaging options, such as tape-and-reel configurations indicated by the TB suffix.
Replacement Considerations
Check for direct substitutes within the EL3H7-G family with matching CTR bins. Verify pinout compatibility and package dimensions before replacing with other manufacturers' equivalents.
