PC810I

Transistor, Photovoltaic Output Optoisolators Overview

The PC810I is a single-channel optoisolator manufactured by Sharp Microelectronics. It features an infrared emitting diode coupled to a silicon NPN phototransistor output. The device provides electrical isolation with a rated voltage of 5000Vrms. It is designed for surface mount applications in a compact 4-SMD (gull-wing) package. The component operates within a temperature range of -30°C to 100°C and supports a maximum forward current of 50 mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Integrates an infrared LED with an NPN phototransistor for signal transmission
• Designed for reliable surface mount assembly on printed circuit boards

Transistor, Photovoltaic Output Optoisolators Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops requiring galvanic separation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'I' against the manufacturer's official datasheet to confirm pinout configuration and material compliance. Ensure the source document explicitly lists the PC810I part number, as generic PC810 listings may refer to different variants or through-hole packages. Cross-reference the package type to confirm it matches the required 4-SMD gull-wing form factor for your design.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel transistor-output isolator is required for low-speed digital signal transmission. Consider the 5000Vrms isolation rating for safety requirements. Verify that the NPN phototransistor output characteristics align with the load requirements of the receiving circuit. Confirm that the surface mount package fits the available board space.

Transistor, Photovoltaic Output Optoisolators Part Context

The PC810I belongs to the Sharp PC810 series of optocouplers. This series is widely used for general-purpose isolation tasks. The 'I' suffix typically denotes a specific tape-and-reel or lead-free variant within the broader PC810 family, distinguishing it from other packaging options like DIP-4.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct replacements such as the PC810X or PC810Y if the 'I' variant is unavailable, ensuring the pinout and electrical parameters match. Other compatible transistor-output optocouplers from different manufacturers may serve as substitutes if isolation voltage and package dimensions are identical.
