EL816(S)(A)(TA)-V

Overview

The EL816(S)(A)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor detector in a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It features a current transfer ratio ranging from 50% to 600% at a forward current of 5mA and collector-emitter voltage of 5V. The component supports a maximum operating temperature of +110°C and complies with RoHS standards.

Feature Summary

• High isolation voltage capability between input and output circuits
• Wide current transfer ratio range for flexible signal transmission
• Compact small outline surface-mount package design
• Extended operating temperature range up to +110°C

Applications

• Programmable controllers
• System appliances and measuring instruments
• Telecommunication equipment
• Home appliances such as fan heaters
• Signal transmission between circuits of different potentials

Procurement Notes

Verify the specific suffix configuration against official Everlight documentation to ensure correct packaging and compliance status. Confirm that the ordering code matches the required lead spacing and termination type. Check for updated regulatory approvals such as UL or VDE recognition numbers relevant to the target market. Ensure compatibility with surface-mount assembly processes given the SMD package type.

Selection Notes

Select this component when high isolation voltage and compact footprint are required for signal coupling. Consider the wide CTR range for applications needing broad gain tolerance. Verify thermal management requirements due to the +110°C operating limit. Ensure the NPN phototransistor output interface matches the receiving circuit design. Compare creepage distance specifications against safety clearance requirements.

Part Context

This part belongs to the EL816 series of photo couplers, which consist of an infrared LED optically coupled to a phototransistor. The series is available in both DIP and SMD packages with various lead spacing options. The EL816(S) designation indicates the surface-mount variant. The series is designed for general-purpose isolation applications requiring reliable signal transmission across isolated domains.

Replacement Considerations

Direct substitutes within the EL816 family include variations with different suffixes for packaging or approval ratings. Cross-brand equivalents may exist but require verification of pinout, isolation voltage, and CTR characteristics. Ensure any replacement maintains the same 4-pin SMD form factor and electrical parameters.
