Overview
The EL816(S)(B)(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor detector to provide electrical isolation. The device features a high isolation voltage of 5000 Vrms between input and output circuits. It operates within a temperature range of -55°C to +110°C and supports a maximum forward current of 50 mA. The component is housed in a compact surface-mount DIP-4 package, ensuring reliable signal transmission across isolated boundaries.
Feature Summary
- High isolation voltage capability between input and output circuits
- Wide operating temperature range for diverse environmental conditions
- Compact surface-mount packaging for space-constrained designs
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix (B)(TA) against the manufacturer's official datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure compliance with RoHS directives and check for UL or VDE approvals required by your target market regulations before finalizing procurement orders.
Selection Notes
Select this component when high voltage isolation is critical for safety or noise immunity. Consider the CTR range and collector-emitter breakdown voltage relative to the load requirements. Verify that the surface-mount footprint matches the PCB layout constraints and thermal management needs of the application design.
Part Context
This part belongs to the EL816 series of optocouplers, which are widely used for general-purpose isolation. The series typically offers various package options and insulation ratings. The EL816(S)(B)(TA) specifically denotes a surface-mount variant with defined mechanical dimensions and termination style suitable for automated assembly processes.
Replacement Considerations
Check for direct pin-compatible substitutes from Everlight or other manufacturers offering equivalent 5000Vrms isolation and NPN phototransistor outputs. Verify that any replacement maintains the same CTR characteristics and package dimensions to ensure seamless integration without redesigning the host circuit board.
