Overview
The EL816(S)(Y)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It features a current transfer ratio ranging from 50% to 600% at a forward current of 5mA and collector-emitter voltage of 5V. The component supports an operating temperature range from -55°C to +110°C and complies with RoHS standards.
Feature Summary
- High isolation voltage capability between input and output circuits
- Wide current transfer ratio range for flexible signal transmission
- Extended operating temperature range suitable for harsh environments
- Compact surface-mount packaging for space-constrained designs
Applications
- Industrial control systems requiring electrical isolation
- Signal transmission across isolated ground potentials
- Switching power supply feedback loops
- Microcontroller interface circuits with voltage level shifting
Procurement Notes
Verify the specific suffix (Y) against the manufacturer datasheet to confirm exact CTR binning and lead configuration. Confirm RoHS compliance status and UL/VDE recognition numbers required for end-product certification. Check availability as distribution channels may vary for this specific SMD variant.
Selection Notes
Select this component when high isolation voltage and wide CTR tolerance are required in a small footprint. Ensure the NPN phototransistor output matches the load requirements. Verify that the surface-mount package dimensions fit the PCB layout constraints compared to through-hole alternatives.
Part Context
This part belongs to the EL816 series of phototransistor optocouplers. The series offers both DIP and SMD options. The SMD variants provide similar electrical characteristics to their through-hole counterparts but with reduced physical size. The series is widely used in applications requiring reliable galvanic isolation.
Replacement Considerations
Direct replacements include other EL816 SMD variants such as EL816(S)(X)(TA)-V or EL816(S1)(Y)(TA)-V, provided pinout and isolation ratings match. Generic equivalents like PC817-SMD may be considered if CTR ranges and isolation voltages are compatible.
