EL816(S)(A)(TU)-V

Overview

The EL816(S)(A)(TU)-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 compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits with a creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of 80 V minimum, maximum forward current of 60 mA, and maximum on-state current of 50 mA. The unit operates within a temperature range of -55 °C to +110 °C and complies with RoHS standards.

Feature Summary

• Compact small outline surface-mount package design
• Wide operating temperature range for industrial environments

Applications

• Signal isolation in microprocessor systems
• Switching power supply feedback loops
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm pinout orientation and lead spacing variations. Ensure compliance requirements match project specifications. Confirm availability status as product lifecycles may change. Cross-reference ordering numbers with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factor are required. Consider the current transfer ratio range and collector-emitter breakdown voltage for circuit compatibility. Evaluate thermal management needs given the wide operating temperature range. Compare against alternative optocouplers if specific package dimensions or isolation ratings differ from system constraints.

Part Context

This part belongs to the EL816 series of transistor output optocouplers. The series includes various packaging options such as DIP and SMD configurations. These devices are widely used for electrical isolation in digital and analog signal transmission applications. The manufacturer offers multiple variants with different isolation ratings and package styles within this family.

Replacement Considerations

Equivalent parts must match the 5000 Vrms isolation rating and NPN phototransistor output type. Verify that substitute components offer comparable current transfer ratios and collector-emitter breakdown voltages. Ensure physical footprint compatibility for surface-mount installation. Check for identical regulatory approvals if required by the application.
