Overview
The EL3H4(B)(EA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode reverse-parallel connected with another, coupled to an NPN phototransistor. The device provides electrical isolation with a rated isolation voltage of 3750 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80V, a forward current of 50mA, and a typical current transfer ratio of 150% at 1mA. Operating temperatures range from -55°C to +100°C.
Feature Summary
- Dual anti-parallel infrared LED input configuration for AC/DC signal compatibility
- NPN phototransistor output stage for digital switching applications
- High insulation voltage rating for robust circuit isolation
- Surface mount SSOP-4 package design for compact PCB integration
Applications
- AC mains detection circuits
- Microcontroller interface isolation
- Solid-state relay driver circuits
- Industrial control system signal isolation
Procurement Notes
Verify the specific suffix EA against official Everlight documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives if required by your manufacturing process. Cross-reference the manufacturer part number with distributor catalogs to confirm current production status and availability constraints before finalizing procurement plans.
Selection Notes
Select this component when dual-directional input capability is required for AC signals without external rectification. The NPN output suits standard logic interfacing. Verify that the 80V collector voltage meets the load requirements. Consider the thermal dissipation limits within the SOIC-4 footprint during high-duty cycle operations.
Part Context
This part belongs to the EL3H4 series of transistor output optocouplers. The series is designed for general-purpose isolation in industrial and consumer electronics. Variations in suffixes typically denote packaging formats or environmental compliance levels rather than functional differences.
Replacement Considerations
Check for direct equivalents such as the EL3H4(A)(EA)-VG or EL3H4(TA)-G, ensuring pinout and electrical ratings match. Verify that substitute components maintain the same isolation voltage and current transfer ratio characteristics.
