Overview
The EL3H7(J)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides an isolation voltage of 3750 Vrms. The device operates within a temperature range of -55°C to +110°C. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum collector current of 50mA, and a forward current of 50mA. The typical forward voltage is 1.2V. The Current Transfer Ratio (CTR) ranges from 100% to 200% at a forward current of 5mA. The unit is housed in a compact 4-pin SSOP package.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for digital signal transmission
- Designed for surface-mount assembly in space-constrained applications
Applications
- Industrial control systems requiring signal isolation
- Microcontroller interface circuits for noise immunity
- Power supply feedback loops for safety compliance
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest datasheet to ensure compatibility with required CTR bins and packaging formats. Confirm that the SSOP footprint matches the target PCB design constraints. Check for any RoHS or REACH compliance updates relevant to the manufacturing date code. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.
Selection Notes
Select this component when a small form factor is critical for the design. The 100-200% CTR bin offers moderate gain for standard logic interfacing. Consider the 3750 Vrms isolation rating for basic insulation requirements. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions. Compare pin-out compatibility with existing designs if replacing legacy components.
Part Context
This part belongs to the EL3H7 series of ultra-small solid-state relays and optocouplers. The series is characterized by its compact SSOP package and robust isolation capabilities. It serves as a bridge for transferring digital signals across isolated boundaries while maintaining electrical safety standards. The family includes various CTR bins and packaging options to suit different production needs.
Replacement Considerations
Direct substitutes may include other parts from the EL3H7 family with matching CTR specifications, such as EL3H7(B)(TA)-VG or EL3H7(C)(TA)-G, provided the pinout and package dimensions are identical. Verify that alternative components meet the same isolation voltage and temperature ratings.
