Overview
The EL816(S1)(C)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output circuits. The device operates within a temperature range of -55°C to +110°C and supports a maximum forward current of 60 mA with a nominal forward voltage of 1.4 V. Key electrical parameters include a collector-emitter breakdown voltage of at least 80 V, a maximum dark current of 100 nA, and a current transfer ratio ranging from 50% to 600% at IF=5mA and VCE=5V. It is RoHS compliant and UL/VDE approved.
Feature Summary
- High isolation voltage capability of 5000 Vrms ensures safe separation between input and output circuits.
- Wide operating temperature range extending up to +110°C for reliable performance in demanding environments.
- Compact surface-mount package design facilitates automated assembly and space-constrained applications.
Applications
- Industrial control systems requiring signal isolation
- Communication equipment for noise immunity
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix configuration against the official Everlight datasheet to ensure compatibility with required isolation standards and packaging type. Confirm RoHS compliance status and approval numbers (UL/VDE) match project specifications. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure storage conditions adhere to moisture sensitivity levels defined in the manufacturer's guidelines.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are critical. Compare current transfer ratio requirements against application needs, noting the 50-600% range. Consider the surface-mount package for PCB layout constraints. Verify that the NPN phototransistor output aligns with downstream circuit logic levels. Evaluate thermal management requirements given the +110°C maximum junction temperature rating.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series is designed for general-purpose isolation applications. Variants differ primarily in packaging (SMD vs DIP) and reel/tape configurations. The EL816 family is widely recognized for its reliability in industrial and consumer electronics markets.
Replacement Considerations
Direct substitutes may include other EL816 variants with compatible pinouts and electrical characteristics. Verify equivalent isolation voltage and CTR ranges before substitution. Consult Everlight's official cross-reference documentation for validated replacements.
