Overview
The EL816(S)(D)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact SMD4 package. The device provides high electrical isolation of 5000 Vrms between input and output circuits, ensuring safety compliance. Key electrical parameters include a collector-emitter breakdown voltage of 80 V, a maximum forward current of 60 mA, and a typical forward voltage of 1.2 V. The current transfer ratio ranges from 300% to 600% at a forward current of 5 mA and collector-emitter voltage of 5 V. It supports a continuous output current of 50 mA and operates within a temperature range of -55°C to +110°C.
Feature Summary
- High isolation voltage capability between input and output sides
- Compact surface mount design for space-constrained applications
- Wide operating temperature range suitable for industrial environments
Applications
- Digital logic signal transmission and conversion
- Power supply control and switching circuits

Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to confirm pinout configuration, lead spacing, and tape-and-reel specifications. Ensure that the procurement source provides documentation confirming RoHS compliance and UL/VDE recognition status as stated in the product description. Cross-reference the part number with the latest Everlight Electronics release notes to confirm availability and any potential obsolescence notices before finalizing orders.
Selection Notes
Select this component when high isolation voltage and compact surface mount packaging are required for signal isolation. Consider the current transfer ratio range and operating temperature limits to ensure compatibility with the target circuit environment. Verify that the input forward current requirements align with the driving source capabilities and that the output voltage ratings meet the load requirements.
Part Context
This device belongs to the EL816 series of optocouplers, which consist of an infrared LED optically coupled to a phototransistor. The series offers both DIP and SMD package options to accommodate different mounting needs. The EL816(S)(D)(TB)-V specifically utilizes a surface mount form factor designed for automated assembly processes while maintaining the performance characteristics of the broader family.
Replacement Considerations
Direct replacements must match the 5000 Vrms isolation rating, SMD4 package type, and NPN phototransistor output configuration. Verify that substitute components offer comparable current transfer ratios and operating temperature ranges to ensure functional equivalence in existing designs.
