EL817(S)(D)(TA)-G

Overview

The EL817(S)(D)(TA)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor detector, housed in a surface-mount 4-pin package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum forward current of 50 mA, and a typical rise/fall time range of 3 µs to 4 µs. It operates within a temperature range of -55 °C to +110 °C and complies with RoHS standards.

Feature Summary

High isolation voltage capability between input and output for circuit protection
Compact surface-mount design suitable for automated assembly processes
Wide operating temperature range supporting diverse environmental conditions

Applications

Signal isolation in industrial control systems
Power supply feedback loops
Microcontroller interface circuits
