PC827CD

Transistor, Photovoltaic Output Optoisolators Overview

The PC827CD is a dual-channel photovoltaic output optoisolator manufactured by Sharp Microelectronics. It provides electrical isolation with a voltage rating of 5000Vrms. The device features two independent channels within an 8-DIP package. Key electrical characteristics include a minimum Current Transfer Ratio (CTR) of 200% at a forward current of 5mA, and a maximum CTR of 600% under the same conditions. This component is designed for high-density mounting applications requiring robust signal transmission across isolated circuits.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• Photovoltaic output mechanism for low-power switching
• High voltage isolation capability of 5000Vrms
• Compact 8-DIP package suitable for dense PCB layouts

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission between microcontrollers and power stages
• Safety-critical circuit interfaces
• Data communication links with noise immunity requirements

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify part authenticity through authorized distributors as this component is marked obsolete. Confirm availability of substitute models from Sharp or compatible third-party manufacturers. Ensure that any replacement maintains identical pinout, isolation voltage, and CTR specifications to guarantee system compatibility without redesigning the host circuit board.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required in a compact form factor. Consider the photovoltaic output type for applications needing zero quiescent current in the output stage. Evaluate the 5000Vrms isolation rating against system safety standards. Verify that the 200-600% CTR range meets the drive requirements of the receiving logic or transistor input.

Transistor, Photovoltaic Output Optoisolators Part Context

The PC827CD belongs to Sharp's PC827 series of photocouplers, which are designed for high-density mounting. It is distinct from single-channel variants like the PC817 and quad-channel versions such as the PC847. The 'CD' suffix typically denotes specific packaging or tape-and-reel options within the standard PC827 family, though exact suffix definitions should be confirmed via official documentation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Official substitutes may include other Sharp dual-channel photovoltaic optocouplers or equivalent parts from manufacturers like Vishay or Broadcom. Ensure replacements match the 8-DIP package and 5000Vrms isolation rating. Cross-reference CTR specifications to ensure adequate signal transfer efficiency in the target application.
