Overview
The EL216 is a single-channel phototransistor optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode coupled to an NPN phototransistor with a base terminal for sensitivity control. The device provides electrical isolation with a rated insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 60 mA, a collector-emitter saturation voltage of 0.4 V at 10 mA, and a rise time of 1.6 µs. The current transfer ratio exceeds 50% at a forward current of 1 mA. It is housed in an 8-pin SOP package.
Feature Summary
- Integrates an infrared LED with an NPN phototransistor featuring a base pin for adjustable sensitivity.
Applications
- Signal isolation in industrial control systems
- Switching applications in power supplies
- Logic signal interfacing between different voltage domains
Procurement Notes
Verify the specific ordering suffix (e.g., TA, -V) as it determines packaging type such as tube or reel. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current production status, as some variants may be discontinued or subject to limited supply constraints.
Selection Notes
Select this component when high isolation voltage and moderate speed are required. The base pin allows for customization of switching characteristics. Ensure the input current does not exceed the 60 mA maximum rating. Verify that the output saturation voltage meets the logic level requirements of the downstream circuitry.
Part Context
This part belongs to Everlight's family of transistor output optocouplers designed for general-purpose isolation. It utilizes standard SOP-8 surface mount technology to facilitate automated assembly. The design focuses on providing reliable signal transmission across isolated barriers while maintaining compact board space.
Replacement Considerations
Direct substitutes must match the 8-pin SOP package, NPN phototransistor output, and similar isolation voltage ratings. Verify pinout compatibility and electrical specifications such as CTR and rise time before substitution.
