EL816(S)(C)(TB)

Overview

The EL816(S)(C)(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact surface-mount DIP-4 package. The device provides high isolation voltage of 5000 Vrms between input and output circuits, with a creepage distance exceeding 7.62 mm. It features a current transfer ratio ranging from 50% to 600% at a forward current of 5 mA and collector-emitter voltage of 5 V. The component supports a maximum operating temperature of 110°C and complies with RoHS standards.

Feature Summary

• High isolation voltage capability between input and output circuits
• Compact small outline surface-mount package design
• Wide current transfer ratio range for signal transmission
• Compliant with international safety approvals including UL and VDE

Applications

• Industrial control systems requiring electrical isolation

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct pinout and performance characteristics. Confirm RoHS compliance status and relevant safety certifications such as UL or VDE for your target market. Check lifecycle status as availability may vary. Ensure the selected variant matches your required packaging type and thermal specifications before finalizing procurement.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factor are required. Consider the current transfer ratio range and operating temperature limits for your application environment. Verify that the NPN phototransistor output suits your circuit logic requirements. Compare alternative packages if space constraints differ from the standard SMD-4 footprint.

Part Context

This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series offers various packaging options including through-hole and surface-mount configurations. These devices are designed for general-purpose isolation applications where reliable signal transmission and electrical safety are critical. The series maintains consistent core performance metrics across different physical package variants.

Replacement Considerations

Direct replacements must match the 5000 Vrms isolation rating and NPN phototransistor output type. Verify equivalent current transfer ratio ranges and package dimensions for board compatibility. Consult manufacturer cross-reference lists for confirmed substitutes with identical electrical characteristics and safety approvals.
