Overview
The EL816(S1)(TD)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It consists of an infrared emitting diode optically coupled to an NPN phototransistor detector. The device provides high isolation voltage between input and output, rated at 5000 Vrms. It features a current transfer ratio ranging from 50% to 600% when tested at a forward current of 5mA and collector-emitter voltage of 5V. The component supports a maximum forward current of 60mA and a collector-emitter breakdown voltage of 80V minimum. It operates within a temperature range of -55°C to +110°C and is available in a compact surface-mount DIP-4 package.
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
- Compliant with lead-free and RoHS environmental standards
Applications
- Signal isolation in industrial control systems

Procurement Notes
Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required packaging and approval certifications. Confirm that the selected variant matches the intended isolation voltage and current transfer ratio specifications for the target application environment.
Selection Notes
Select this component based on its 5000 Vrms isolation rating and wide operating temperature range. Ensure the circuit design accommodates the specified current transfer ratio variations. Verify that the surface-mount package dimensions fit the PCB layout constraints and that the thermal management strategy supports the maximum junction temperature limits defined in the technical documentation.
Part Context
This part belongs to the EL816 series of optocouplers produced by Everlight Electronics. The series utilizes an infrared LED coupled to a phototransistor to provide electrical isolation. The EL816 family is widely recognized for its reliability in isolating low-voltage control signals from higher-voltage power circuits in various electronic assemblies.
Replacement Considerations
Consult official substitution lists for compatible equivalents. Cross-reference pinouts and electrical parameters such as CTR and isolation voltage before replacing.
