EL816(S1)(TA)

Overview

The EL816(S1)(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode optically coupled to an NPN phototransistor detector housed in a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits with a creepage distance exceeding 7.62 mm. It supports a wide operating temperature range from -55°C to +110°C and complies with RoHS standards. Key electrical parameters include a minimum collector-emitter breakdown voltage of 80 V, maximum forward current of 50 mA, and typical current transfer ratio ranging from 50% to 600% at specified test conditions.
