EL817(S1)(D)(TB)-V

Overview

The EL817(S1)(D)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It integrates an infrared emitting diode with a phototransistor detector to provide electrical isolation between input and output circuits. The device features a surface-mount SMD package with four pins and complies with RoHS standards. Key electrical specifications include a maximum collector-emitter breakdown voltage of 35 V, a maximum forward current of 0.05 A, and a maximum forward voltage of 1.4 V. The unit offers a high isolation voltage of 5000 V rms and supports an operating temperature range from -55 °C to +110 °C.

Feature Summary

Provides high isolation voltage between input and output for safe signal transmission
Integrates an infrared LED optically coupled to a phototransistor detector
Designed in a compact small outline surface-mount package

Applications

Industrial control systems requiring signal isolation
Power management circuitry
Communication equipment

Procurement Notes

Verify the specific suffix (TB) against the manufacturer's official datasheet to confirm tape-and-reel packaging details and exact pinout configuration. Ensure compliance requirements such as UL and VDE approvals match the project specifications. Cross-reference the part number with the latest Everlight documentation to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a surface-mount solution is required for galvanic isolation in low-power applications. The 5000 Vrms isolation rating makes it suitable for environments with significant potential differences between circuits. Consider the 35 V collector-emitter voltage limit and 50 mA maximum current capacity to ensure compatibility with downstream logic or switching loads within the design constraints.

Part Context

This device belongs to the EL817 series, which consists of infrared emitting diodes coupled to phototransistor detectors. The series is available in various packages including DIP and SMD formats. The EL817(S1)(D)(TB)-V specifically utilizes a surface-mount configuration, distinguishing it from through-hole variants while maintaining the core optical coupling technology and isolation characteristics defined by the broader family.
