Overview
The EL816(A) is a single-channel transistor output optocoupler from Everlight Electronics. It integrates an infrared emitting diode optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output with a creepage distance exceeding 7.62 mm. It operates within a temperature range of -55°C to +110°C. The current transfer ratio ranges from 50% to 600% at IF=5mA, VCE=5V. Maximum forward current is 50 mA or 60 mA depending on variant, with collector-emitter breakdown voltage of 80 V.
Feature Summary
- High isolation voltage capability between input and output circuits
- Wide operating temperature range suitable for industrial environments
- Compact small outline package design available in DIP and SMD options
- Compliant with RoHS standards and lead-free manufacturing
Applications
- Programmable controllers
- System appliances and measuring instruments
- Telecommunication equipment
- Home appliances such as fan heaters
- Signal transmission between circuits of different potentials
Procurement Notes
Verify the specific suffix designation (e.g., M, A, S, X, TD) against the manufacturer datasheet to confirm pinout, packaging type, and electrical tolerances. Confirm availability status as some variants may be discontinued or have restricted supply. Ensure compliance requirements match project specifications before ordering.
Selection Notes
Select based on required isolation voltage and operating temperature range. Choose DIP or SMD package according to board layout constraints. Verify current transfer ratio requirements for signal integrity. Check for specific safety approvals like UL or VDE if required by end-use regulations.
Part Context
The EL816 series consists of infrared emitting diodes optically coupled to phototransistor detectors. Available in 4-pin DIP packages with wide-lead spacing and surface mount options. Designed for general-purpose isolation applications requiring reliable signal transmission across isolated boundaries.
Replacement Considerations
Check for direct substitutes within the EL816 family such as EL816(M) or EL816(S). Verify pin compatibility and electrical parameters before substitution. Consult manufacturer documentation for cross-reference lists.
