EL1118(TA)-VG

Overview

The EL1118(TA)-VG is a transistor output optocoupler manufactured by Everlight Electronics. It features a single channel with an NPN phototransistor output and includes a base terminal for enhanced switching performance. The device utilizes a 5-pin long creepage SOP package designed for surface mount applications. It provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. The component operates within a temperature range of -55°C to +110°C and has a maximum power dissipation of 250 mW.

Procurement Notes

Verify current manufacturing status as this part may be obsolete or subject to change. Confirm package dimensions and pinout compatibility during integration. Ensure compliance with RoHS directives if required by the target market. Check for authorized distribution channels to avoid counterfeit components. Validate thermal management requirements based on the specified power dissipation limits.

Selection Notes

Select this component when base-driven phototransistor performance is required for faster switching than standard versions. Consider the 5-pin SOP footprint constraints against available board space. Evaluate the 5000 Vrms isolation requirement against system safety standards. Compare operating temperature ranges with environmental conditions. Verify that the NPN output configuration matches the load interface design.
