Overview
The EL3H4(A)(EA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode reverse-parallel connected to another, coupled to an NPN phototransistor. Key electrical parameters include a maximum collector-emitter voltage of 80V, a forward current of 50mA, and an isolation voltage of 3750 Vrms. The device operates within a temperature range of -55°C to 100°C and has rise/fall times of 6µs/8µs.
Feature Summary
- Dual anti-parallel infrared LED input configuration for AC or DC signal isolation
- NPN phototransistor output stage providing digital switching capability
- High insulation voltage rating ensuring safe separation between input and output circuits
Applications
- Microcontroller interface circuits requiring galvanic isolation
- Solid-state relay driver applications
- Signal transmission in noisy industrial environments
Procurement Notes
Verify the specific suffix (EA) against the manufacturer's latest datasheet to confirm package dimensions and tape/reel specifications. Ensure compliance with RoHS directives as indicated in distributor records. Confirm availability status as some sources list this part as discontinued or limited supply.
Selection Notes
Select this component when dual-input LED configuration is required for AC line sensing or simplified biasing. Compare rise and fall times against system timing requirements. Verify that the 80V output voltage rating exceeds the load requirements. Check thermal dissipation limits if operating near maximum junction temperatures.
Part Context
This part belongs to the EL3H4 series of transistor output optocouplers. Variants differ primarily by packaging type (SOIC vs SSOP) and reel specifications. The EA suffix typically denotes a specific surface-mount package variant produced by Everlight for automated assembly processes.
Replacement Considerations
Check for direct substitutes such as EL3H4(A)(TA)-VG or EL3H4(A)(TB)-VG from the same manufacturer, noting differences in package width and pin spacing. Cross-reference with other single-channel transistor optocouplers offering similar isolation voltages and CTR ranges.
