Overview
The EL816(C) 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 of 5000 Vrms between input and output, with a minimum collector-emitter breakdown voltage of 80 V. It supports a maximum forward current of 60 mA and a collector current of 50 mA. The component operates within a temperature range of -55°C to +110°C and features a current transfer ratio ranging from 50% to 600% at IF=5mA and VCE=5V.
Feature Summary
- High isolation voltage capability of 5000 Vrms between input and output circuits
- Wide operating temperature range extending up to +110°C for robust performance
- Compact small outline package design suitable for space-constrained applications
- Compliant with RoHS standards and approved by major safety agencies including UL and VDE
Applications
- Signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm pinout configuration and packaging type. Ensure compliance requirements such as RoHS and specific agency approvals match project specifications. Confirm availability status as distribution channels may vary. Cross-reference datasheet parameters with system electrical requirements before procurement.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required. Verify that the NPN phototransistor output matches the load interface needs. Check if the specific CTR range meets signal transmission requirements. Consider package compatibility with existing PCB layouts. Confirm safety certification approvals are valid for the target market.
Part Context
The EL816 series comprises single-channel optocouplers featuring an infrared LED coupled to a phototransistor. These devices are available in various packages including DIP-4 and SMD options. The series is designed for general-purpose isolation applications requiring reliable signal transmission with electrical separation between circuits.
Replacement Considerations
Direct substitutes include other EL816 variants with compatible pinouts and electrical characteristics. Verify equivalent isolation voltage and current transfer ratios when selecting alternatives. Ensure replacement components meet the same safety approval standards.
