Overview
The EL827S1(TA)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and NPN phototransistors in an 8-pin DIP package. Key electrical parameters include a minimum collector-emitter voltage of 80 V, a maximum forward current of 60 mA, and a typical forward voltage of 1.4 V. The device offers a high isolation voltage of 5000 Vrms and a current transfer ratio ranging from 50% to 600% at an input current of 5 mA. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High insulation voltage between input and output circuits
- Wide operating temperature range for industrial environments
- RoHS compliant and lead-free construction
Applications
- Digital logic transmission and conversion
- Power supply control and switching circuits
- Electrical isolation between circuit stages
- Impedance transformation in isolated systems
Procurement Notes
Verify the specific suffix (TA) against the manufacturer's latest datasheet to confirm pinout and packaging dimensions. Ensure compliance with RoHS directives if required by the target market. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any recent design changes or obsolescence notices from Everlight Electronics before finalizing procurement plans.
Selection Notes
Select this component when dual-channel isolation is required within a single package footprint. The 80 V collector-emitter voltage rating suits low-voltage digital interfaces. Verify that the 50-600% CTR range meets the drive requirements of the receiving logic. Consider the 8-pin DIP form factor for through-hole mounting constraints. Confirm thermal management capabilities for operation up to 110°C.
Part Context
This device belongs to the EL827 series of transistor output optocouplers. It shares functional similarities with other variants like EL827S(TB)-V but differs in package type and specific mechanical dimensions. The series is designed for general-purpose isolation applications requiring reliable DC input and transistor output characteristics.
Replacement Considerations
Direct substitutes may include EL827S(TB)-V for similar electrical performance in different packages. Other dual-channel optocouplers with matching 5000 Vrms isolation and 80 V Vceo ratings should be evaluated for pin compatibility and CTR specifications.
