Overview
The EL816(S1)(X)(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode optically coupled to an NPN phototransistor detector. The device features a high isolation voltage of 5000 Vrms between input and output circuits, with a creepage distance exceeding 7.62 mm. It supports a wide operating temperature range from -55°C to +110°C and offers a current transfer ratio (CTR) ranging from 50% to 600% at IF=5mA and VCE=5V. The component is available in surface-mount DIP-4 packaging and complies with RoHS standards.
Feature Summary
- High isolation voltage capability between input and output circuits
- Wide operating temperature range suitable for demanding environments
- Compact surface-mount package design for space-constrained applications
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 official Everlight documentation to ensure correct pinout and electrical characteristics. Confirm compliance requirements such as UL or VDE approvals if mandated by the target application. Check for lead-free status and RoHS certification directly on the datasheet. Ensure the surface-mount variant matches the PCB footprint specifications. Validate the current transfer ratio ranges required for the circuit design before procurement.
Selection Notes
Select this component when high isolation voltage and compact surface-mount form factor are required. Consider the CTR range and collector-emitter breakdown voltage for signal integrity. Evaluate the operating temperature limits against environmental conditions. Compare creepage distances for safety clearance requirements. Verify compatibility with existing PCB layouts for SMD DIP-4 packages.
Part Context
The EL816 series consists of infrared emitting diodes optically coupled to phototransistor detectors. These devices are designed for general-purpose isolation applications. The series includes various packaging options including through-hole and surface-mount variants. They are widely used in industrial and consumer electronics for signal isolation.
Replacement Considerations
Consult official Everlight documentation for direct substitutes within the EL816 family. Verify pinout compatibility and electrical parameter equivalence for alternative optocouplers. Cross-reference isolation voltages and current transfer ratios. Ensure mechanical footprint compatibility for surface-mount installations.
