EL815(S1)(TD)

Overview

The EL815(S1)(TD) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features a Photodarlington output configuration housed in a 4-pin PDIP package. Key electrical parameters include an isolation voltage of 5000 Vrms, a collector-emitter saturation voltage of 1 V maximum, and a forward current rating of 60 mA. The device operates within a temperature range of -55°C to +110°C and offers a current transfer ratio ranging from 50% to 600%.

Feature Summary

High isolation voltage capability for safe signal transmission between isolated circuits.
Photodarlington output structure provides high current transfer efficiency.
Wide operating temperature range suitable for demanding industrial environments.

Applications

Telephone sets and telephone exchange systems
Industrial control circuit isolation
Signal transmission in noisy electrical environments

Procurement Notes

Verify the specific suffix (S1)(TD) against the manufacturer's latest documentation to confirm pinout and packaging details. Check the product lifecycle status as some listings indicate end-of-life or discontinuation. Ensure compliance with RoHS requirements if applicable to your design specifications before finalizing procurement.

Selection Notes

Select this component when high gain is required due to its Photodarlington output type compared to standard phototransistors. Consider the slower rise and fall times inherent to darlington structures when designing for high-speed applications. Verify that the 35V collector-emitter voltage rating meets the load requirements of the target circuit.

Part Context

This part belongs to the EL815 series of photo-couplers from Everlight Electronics. It is designed for general-purpose isolation tasks where moderate speed and high sensitivity are prioritized. The series typically includes various packaging options such as DIP and SMD variants to accommodate different board layout constraints.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Generic replacements may differ in current transfer ratio or isolation voltage ratings. Verify pin compatibility and thermal characteristics before integrating substitute components into existing designs.
