EL816(S1)(C)(TA)-V

Overview

The EL816(S1)(C)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact 4-SMD 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. Key electrical parameters include a maximum collector-emitter breakdown voltage of 80 V, a maximum forward current of 60 mA, and a saturation voltage of 200 mV. The unit operates within a temperature range of -55°C to +110°C and features a typical rise time of 4 µs and fall time of 3 µs.

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required isolation ratings and packaging options. Confirm that the component meets all relevant safety approvals such as UL and VDE for the intended application environment. Check for any lifecycle status changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a surface-mount solution is required for galvanic isolation in low-power signal transmission applications. Ensure the circuit design accommodates the specified current transfer ratio and saturation voltage characteristics. Verify that the physical footprint matches the PCB layout constraints for the 4-SMD package type.

Part Context

This part belongs to the EL816 series of optocouplers from Everlight Electronics. The series typically includes various package options such as DIP and SMD configurations. The S1 suffix generally denotes a specific variant within the product line, often related to lead spacing or package style variations compared to standard DIP versions.

Replacement Considerations

Direct replacements may include other EL816 series variants with compatible pinouts and electrical specifications. Verify that substitute components maintain the same isolation voltage rating and package dimensions to ensure mechanical fit.
