Overview
The EL3H7(D)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a collector-emitter saturation voltage of 200mV maximum and a continuous output current of 50mA. The device provides 3750Vrms isolation voltage and operates within a temperature range of -55°C to +110°C. It utilizes a 4-pin SSOP package (SOIC4_175MIL) for surface mount applications.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features fast switching characteristics with typical rise and fall times of 5μs and 3μs respectively
- Designed for compact surface-mount integration using a small form-factor package
Applications
- Industrial control systems requiring signal isolation
- Microcontroller interface circuits for level shifting
- Power supply feedback loops for safety isolation
Procurement Notes
Verify the specific CTR binning associated with the suffix D, as performance ranges vary across the EL3H7 family. Confirm the package type matches the design footprint, noting that TA indicates SSOP packaging. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet for exact electrical limits before integration.
Selection Notes
Select this component when a compact, high-isolation optocoupler is required for digital signal transmission. The NPN phototransistor output suits standard logic interfacing. Consider the CTR specifications relative to the drive current requirements. Verify compatibility with the target PCB layout due to the small SSOP dimensions.
Part Context
This part belongs to the EL3H7 series of ultra-small optocouplers from Everlight. The series offers various CTR bins and packaging options to suit different design constraints. The EL3H7(D) variant specifically targets applications needing defined gain characteristics within the broader family scope.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify that alternative parts meet the 3750Vrms isolation requirement and the -55°C to +110°C temperature range. Ensure the replacement maintains similar switching speeds and output current capabilities.
