EL816(S)(C)(TB)-V

Overview

The EL816(S)(C)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates 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 terminals, with a creepage distance exceeding 7.62 mm. It operates within a temperature range of -55°C to +110°C and supports a maximum forward current of 50 mA. The component features a current transfer ratio ranging from 50% to 600% at specified test conditions.

Procurement Notes

Verify the specific suffix (S)(C)(TB)-V against official Everlight documentation to confirm pinout orientation and tape-and-reel specifications. Ensure compliance requirements such as RoHS and UL/VDE approvals match project standards. Confirm availability status as distribution channels may vary. Cross-reference datasheet revision dates to ensure parameter accuracy before integration into designs.

Selection Notes

Select this component when high isolation voltage and compact SMD packaging are required for single-channel signal transmission. Consider the CTR range and collector-emitter breakdown voltage for circuit compatibility. Verify thermal management needs given the +110°C operating limit. Compare against through-hole alternatives if board space permits different form factors.

Part Context

This part belongs to the EL816 series of transistor output optocouplers. The series typically includes various package options including DIP and SMD configurations. The EL816 family is designed for general-purpose isolation applications, offering reliability and compliance with international safety standards. Variants differ primarily in lead spacing and packaging format.

Replacement Considerations

Direct replacements include other EL816 series variants with compatible pinouts and electrical characteristics. Verify that substitute components maintain the same 5000 Vrms isolation rating and NPN output configuration. Check for equivalent creepage distances and operating temperature ranges to ensure functional parity in existing designs.
