EL817(S)(C)(TB)-V

Transistor, Photovoltaic Output Optoisolators Overview

The EL817(S)(C)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor detector in a surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output, with a minimum creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of 35 V, maximum forward current of 60 mA, and a nominal current transfer ratio of 200% at 5 mA. It operates within a temperature range of -55 °C to +110 °C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix codes against official Everlight documentation to confirm pinout configuration and packaging type. Ensure compliance with RoHS directives and lead-free requirements as specified in the datasheet. Cross-reference approval numbers such as UL E214129 and VDE 132249 for regulatory adherence. Confirm availability status as distribution channels may vary.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface mount technology is required for the EL817 form factor. Consider the 5000 Vrms isolation rating for safety-critical applications. Verify that the 35 V collector-emitter voltage meets the load requirements. Check if the 200% CTR minimum aligns with switching speed and drive current needs compared to through-hole alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the EL817 series, which typically includes both through-hole DIP and surface-mount variants. The (S) indicates surface mount, while (TB) specifies the tape and reel packaging format. The (C) denotes compliance with specific environmental standards. This variant maintains the core electrical characteristics of the standard EL817 but adapts it for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other EL817 surface mount variants from Everlight or equivalent transistor output optocouplers from manufacturers like Sharp or Vishay, provided pinouts and isolation ratings match.
