EL3H4(A)(TA)-VG

Overview

The EL3H4(A)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode reverse-parallel connected to a phototransistor, housed in a 4-pin SSOP surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a forward current of 50 mA. The device provides an isolation voltage of 3750 Vrms and operates within a temperature range of -55°C to 100°C. Typical switching characteristics include a rise time of 6 µs and a fall time of 8 µs.

Feature Summary

Dual-directional input capability via reverse-parallel infrared LED configuration
High-voltage isolation barrier rated at 3750 Vrms
Green compound encapsulation for enhanced optical transmission
Surface-mount SSOP-4 packaging for automated assembly

Applications

AC line voltage detection circuits
Solid-state relay driver interfaces
Microcontroller signal isolation
Industrial control system inputs

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm pinout compatibility and material compliance. Ensure that the TA tape-and-reel variant matches the required handling specifications for the production environment. Cross-reference the component marking with official Everlight documentation to distinguish between similar family members such as the EL3H4(B) series which may exhibit different switching speeds.

Selection Notes

Select this component when bidirectional AC input sensing is required within a compact surface-mount footprint. The reverse-parallel LED structure eliminates the need for external rectification components in AC applications. Consider the 6 µs rise time for high-speed digital isolation requirements. Verify that the 80 V collector voltage rating exceeds the maximum load voltage in the target circuit design.

Part Context

This part belongs to the EL3H4 series of transistor output optocouplers from Everlight Electronics. The series is designed for general-purpose isolation applications requiring small form factors. The specific (A) designation typically denotes the internal LED configuration and color compound, while (TA) indicates the tape-and-reel packaging format suitable for pick-and-place machinery.
