Overview
The EL816(S1)(B)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features a high isolation voltage of 5000 Vrms between input and output circuits. The device utilizes an NPN phototransistor output with a maximum collector-emitter breakdown voltage of 80 V. Key electrical parameters include a maximum forward current of 60 mA, a typical current transfer ratio ranging from 100% to 200% at 5 mA, and a low saturation voltage of 200 mV. It operates within a temperature range of -55°C to +110°C and is housed in a compact surface-mount 4-SMD package.
Feature Summary
- High insulation voltage capability for safe signal transmission across isolated domains
- Compact surface-mount form factor designed for space-constrained circuit board layouts
- Wide operating temperature range suitable for demanding industrial environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microcontroller interfacing circuits
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct pinout and performance specifications. Confirm RoHS compliance status and packaging type directly with authorized distributors. Cross-reference part numbers carefully as minor variations may indicate different thermal or electrical characteristics.
Selection Notes
Select this component when high isolation voltage and compact SMD packaging are required. Ensure the application current requirements fall within the specified forward current limits. Verify that the operating temperature range meets the environmental conditions of the final assembly. Check compatibility with existing PCB footprints for 4-SMD packages.
Part Context
This component belongs to the EL816 series of transistor output optocouplers produced by Everlight. The series is widely recognized for providing reliable electrical isolation in various electronic applications. The specific model variant indicates a surface-mount configuration with defined electrical characteristics distinct from through-hole versions.
Replacement Considerations
Direct replacements must match the 5000 Vrms isolation rating and 4-SMD package dimensions. Verify equivalent current transfer ratio and saturation voltage specifications. Consult manufacturer cross-reference lists for confirmed compatible part numbers.
