Overview
The EL3H7(EB)-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, with a collector-emitter saturation voltage of 200mV.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for signal transmission
- Designed for surface-mount assembly in compact form factors
Applications
- High-voltage switching applications
- Signal isolation in industrial control systems
- Microcontroller interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure compatibility with required packaging and performance specifications. Confirm RoHS compliance status through the manufacturer's latest product declaration. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a single-channel transistor output optocoupler with 3750 Vrms isolation is required. Ensure the operating temperature range of -55°C to +110°C meets system environmental constraints. Verify that the 50mA collector current rating satisfies the load requirements of the connected circuitry.
Part Context
This component belongs to the EL3H7 series of ultra-small SSOP optocouplers from Everlight. The series offers various configurations distinguished by suffixes indicating current transfer ratio grades and packaging types. This specific variant integrates an infrared emitting diode with an NPN phototransistor in a four-pin surface-mount package.
Replacement Considerations
Equivalent parts include EL3H7(C)(TB)-VG and EL3H7(TA)-VG. Verify pinout compatibility and electrical parameter alignment, such as current transfer ratio and isolation voltage, before substituting.
