EL816(S)(Y)(TB)-V

Overview

The EL816(S)(Y)(TB)-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 surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a minimum collector-emitter breakdown voltage of 80 V, a maximum forward current of 60 mA, and a typical operating temperature range from -55°C to +110°C. The current transfer ratio ranges from 150% to 300% at a forward current of 5 mA.

Feature Summary

• High isolation voltage capability for secure circuit separation
• Compact small outline surface-mount package design
• Wide operating temperature range suitable for industrial environments
• RoHS compliant and lead-free construction

Applications

• Programmable controllers
• System appliances and measuring instruments
• Telecommunication equipment
• Signal transmission between circuits of different potentials

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required creepage distances and isolation ratings. Confirm that the surface-mount variant meets the PCB layout requirements for the intended application. Check for any updated regulatory approvals or compliance certifications relevant to the target market before finalizing procurement decisions.

Selection Notes

Select this component when high isolation voltage and compact surface-mount packaging are required for signal transmission applications. Ensure the current transfer ratio specifications meet the logic level requirements of the receiving circuit. Verify that the thermal management capabilities align with the expected operating temperature range of the final assembly environment.

Part Context

This part belongs to the EL816 series of photo couplers, which consist of infrared emitting diodes optically coupled to phototransistor detectors. The series is available in both wide-lead spacing DIP packages and SMD options. The EL816 series is designed for general-purpose isolation applications requiring reliable signal transmission between isolated circuits.

Replacement Considerations

Cross-reference with other EL816 series variants such as EL816(S)(X)(TB)-V or EL816(S)(TA)-FV for alternative CTR ranges or package styles. Verify pinout compatibility and isolation voltage ratings when substituting with components from other manufacturers offering similar transistor output optocouplers.
