Overview
The EL817(S)(C)(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It is designed for surface mount applications in a compact 4-SMD package. The component supports a collector-emitter breakdown voltage of 35 V and a maximum continuous collector current of 50 mA. Operating temperature range spans from -55 °C to +110 °C.
Feature Summary
- High isolation voltage capability between input and output circuits
- Compact surface mount package design for space-constrained applications
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics with safety isolation requirements
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure correct pinout and performance characteristics. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Ensure the selected variant matches the required packaging format for automated assembly processes.
Selection Notes
Select this component when high isolation voltage and compact surface mount form factor are required. Consider the CTR range and switching speed specifications relative to the target application frequency. Verify thermal management requirements given the wide operating temperature range and power dissipation limits of the SMD package.
Part Context
This part belongs to the EL817 series of optocouplers, which are widely used for electrical isolation in various electronic circuits. The series offers different package options including DIP and SMD variants. The EL817(S)(C)(TA)-VG specifically denotes the surface mount version with tape and reel packaging, suitable for high-volume manufacturing.
Replacement Considerations
Direct substitutes include other EL817 series variants such as EL817(S)(C)-V or EL817(S1)(C)(TU)-V, provided pin compatibility and electrical parameters match. Verify isolation voltage and CTR specifications before substitution to ensure circuit functionality remains unaffected.
