EL215

Overview

The EL215 is a single-channel optocoupler manufactured by Everlight Electronics Co., Ltd. It features an infrared emitting diode coupled to an NPN phototransistor with a base terminal for improved switching performance. The device is housed in an 8-pin Small Outline Package (SOP). Key electrical specifications include a collector-emitter voltage of 30V and a collector current of 50mA. The unit provides high isolation capability with an insulation voltage rating of 3750 Vrms. It is designed for DC input and DC output applications, ensuring reliable signal transmission across isolated circuits.

Feature Summary

• Integrates an infrared LED with an NPN phototransistor featuring a dedicated base pin for enhanced control and faster response times.
• Provides robust electrical isolation between input and output circuits to protect sensitive components from voltage spikes.
• Utilizes an 8-pin SOP package design suitable for surface mount assembly and automated placement processes.

Applications

• Signal isolation in industrial control systems
• Interface circuits between microprocessors and power devices
• Switching applications in telecommunications equipment

Procurement Notes

Verify the specific suffix variant required, as the base part number may correspond to different packaging or compliance versions. Confirm availability status, as this component has been reported as discontinued in certain regions. Ensure that the selected supplier provides valid traceability documentation and adheres to RoHS compliance requirements specified in the official datasheet.

Selection Notes

Select this component when a transistor output optocoupler with a base connection is required for improved switching characteristics. Consider the 3750 Vrms isolation rating for safety-critical applications. Evaluate the 8-pin SOP footprint against available board space constraints. Verify that the 30V collector-emitter voltage meets the load requirements of the target circuit design.

Part Context

The EL215 belongs to Everlight's family of transistor output optocouplers. These devices are engineered for general-purpose isolation tasks where moderate speed and high reliability are necessary. The inclusion of a base terminal distinguishes it from standard phototransistor optocouplers by allowing external biasing for optimized performance.
