Overview
The EL817S(D)(TA)-V is a single-element transistor output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode optically coupled to a phototransistor detector in a surface-mount package. The device provides high isolation voltage of 5000 V rms between input and output, with a creepage distance exceeding 7.62 mm. It operates within a temperature range of -55 °C to +110 °C. Key electrical parameters include a minimum collector-emitter breakdown voltage of 35 V, a maximum forward current of 50 mA, and a nominal current transfer ratio ranging from 50% to 600% at IF=5mA and VCE=5V. The component is RoHS compliant and UL recognized.
Feature Summary
- High isolation voltage capability between input and output channels
- Compact small outline surface-mount package design
- Wide operating temperature range suitable for industrial environments
Applications
- General purpose signal isolation in digital circuits
- Interface between microcontrollers and power switching devices
- Isolation in measurement and control systems
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to confirm pinout configuration, CTR grading, and packaging type. Ensure compliance requirements such as RoHS and UL recognition match project specifications. Cross-reference the part number with the latest Everlight documentation to avoid obsolete or variant substitutions.
Selection Notes
Select this component when high isolation voltage and compact SMD form factor are required. Consider the current transfer ratio range and operating temperature limits relative to the application environment. Verify that the surface-mount package aligns with PCB layout constraints and assembly capabilities.
Part Context
This part belongs to the EL817 series of transistor output optocouplers. The series combines an infrared LED with a phototransistor for electrical isolation. Variants differ primarily in packaging style, CTR grading, and approval certifications while maintaining core functional characteristics.
Replacement Considerations
Consult official substitution lists for equivalent transistor output optocouplers with matching isolation voltage and package dimensions. Verify pin compatibility and electrical parameter overlap before replacement.
