Overview
The EL827S(TB) is a dual-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and phototransistors in an 8-pin DIP package to provide electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms, ensuring robust safety standards for signal transmission. It supports DC input signals and utilizes NPN phototransistor outputs capable of handling up to 50 mA per channel with a maximum output voltage of 80 V. The component operates within a temperature range of -55°C to +110°C, making it suitable for demanding industrial environments requiring reliable galvanic isolation.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High insulation voltage rating for enhanced safety
- NPN phototransistor output structure
- Wide operating temperature range
Applications
- Digital logic signal 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 designation against official Everlight documentation to confirm pinout compatibility and packaging type. Confirm RoHS compliance status through current datasheets as regulatory requirements may change. Check for active manufacturing status or obsolescence notices prior to procurement planning. Ensure the selected variant matches the required isolation voltage and channel count for the target application design.
Selection Notes
Select this component when dual-channel isolation is required within a standard DIP footprint. Verify that the 5000 Vrms isolation rating meets the safety requirements of the application. Ensure the NPN output type aligns with the downstream circuit interface needs. Consider the operating temperature range limits relative to the environmental conditions of the final assembly.
Part Context
The EL827 series represents Everlight's line of transistor output optocouplers designed for general-purpose isolation applications. The EL827S(TB) specifically denotes the dual-channel variant housed in an 8-pin DIP package. This family is commonly used in industrial automation and consumer electronics where cost-effective galvanic isolation is necessary for signal integrity and safety compliance.
Replacement Considerations
Consult official Everlight substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers. Ensure any substitute part maintains the same isolation voltage and channel configuration.
