Overview
The PC824A is a dual-channel photovoltaic output optoisolator manufactured by Sharp Microelectronics. It provides high isolation voltage of 5000Vrms between input and output circuits. The device features AC and DC input compatibility with transistor output configuration. It is housed in a compact 8-DIP package with a standard 0.300-inch (7.62mm) pin spacing. This component is designed for signal transmission across isolated boundaries while maintaining electrical safety standards.
Feature Summary
- Dual-channel configuration for independent signal isolation
- High dielectric strength between input and output sides
- Compatibility with both AC and DC input signals
- Compact dual-in-line physical footprint
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits between microcontrollers and power stages
- Safety-critical equipment needing high voltage barrier protection
Procurement Notes
Verify the obsolete status of this part number before procurement planning, as it is no longer manufactured by Sharp Microelectronics. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any sourced units meet original specification requirements for isolation voltage and channel count. Check for potential counterfeit risks when sourcing discontinued components from non-authorized channels.
Selection Notes
Consider the dual-channel requirement and 5000Vrms isolation rating when evaluating alternatives. Verify package compatibility with existing PCB layouts, specifically the 8-DIP form factor. Assess whether the photovoltaic output type meets the load requirements of the target application circuit. Review current supply chain constraints for discontinued Sharp components.
Part Context
This component belongs to Sharp's PC series of optoisolators, which are widely used for electrical isolation in electronic circuits. The PC824A specifically offers two isolated channels within a single package, distinguishing it from single-channel variants like the PC814. It represents a legacy product line from Sharp Microelectronics focused on reliable signal transfer across isolated domains.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify equivalent components based on matching specifications such as isolation voltage, channel count, and package type from other manufacturers.
