EL215(TB)

Overview

The EL215(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor with a base terminal for enhanced switching speed control and stability. The device provides electrical isolation between input and output circuits, rated at 3750 Vrms insulation voltage. It is housed in an 8-pin Small Outline Package (SOP) and is designed for applications requiring reliable signal transmission across isolated domains.

Feature Summary

• Single-channel configuration with integrated base connection on the phototransistor output
• High insulation voltage rating of 3750 Vrms for robust circuit isolation
• NPN phototransistor output type suitable for digital signal interfacing

Applications

• Industrial control systems requiring signal isolation
• Computer peripheral interface circuits
• Power supply feedback loops

Procurement Notes

Verify component authenticity through official Everlight channels or authorized distributors. Confirm package integrity and lead time constraints due to potential supply chain variability. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design requirements.

Selection Notes

Select this component when base-controlled switching speed is critical for the application. The SOP-8 package offers space efficiency for dense PCB layouts. Consider the 3750 Vrms isolation rating for safety-critical interfaces. Evaluate thermal management needs based on the specific operating current conditions defined in the official datasheet.

Part Context

The EL215 series belongs to Everlight's portfolio of transistor output optocouplers. These devices are engineered for general-purpose isolation tasks. The TB suffix typically denotes specific packaging or tape-and-reel configurations within the product line. This model represents a standard solution for isolating low-voltage logic from higher voltage loads.

Replacement Considerations

Consult official Everlight documentation for direct cross-references. Verify that any substitute maintains the 8-pin SOP footprint and NPN transistor output topology. Ensure equivalent insulation voltage ratings are met to preserve system safety standards.
