K847PH

Transistor, Photovoltaic Output Optoisolators Overview

The K847PH is a quad optocoupler manufactured by Vishay Semiconductor Opto Division, featuring four independent channels with phototransistor outputs. It utilizes a DC input configuration and is housed in a 16-pin PDIP package for through-hole mounting. The device provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a maximum forward current of 60 mA and a minimum current transfer ratio of 50%. This component is designed for reliable signal transmission in industrial applications requiring high-voltage isolation.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging format, such as tube or reel, as this affects handling procedures. Ensure that the procurement documentation explicitly references the Vishay Semiconductor Opto Division manufacturer designation to avoid confusion with similar part numbers. Cross-check the datasheet revision date against your design requirements to guarantee compatibility with current manufacturing standards and material specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the K847PH when multiple isolated channels are required in a compact form factor. Consider its phototransistor output speed characteristics against your system's data rate requirements. Evaluate the 16-pin DIP footprint availability on your PCB layout to ensure proper mechanical fit. Confirm that the 5000 Vrms isolation rating meets the safety regulations applicable to your target market and application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to Vishay's family of optocouplers designed for general-purpose isolation. It complements other quad-channel variants by offering a standard DIP package solution. The K847PH serves as a bridge between low-voltage control logic and higher-voltage power stages, maintaining signal integrity while preventing ground loops and noise interference in complex electronic assemblies.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other quad-channel phototransistor optocouplers with compatible pinouts and isolation ratings. Verify that any replacement maintains the same 16-pin DIP configuration and 50% minimum current transfer ratio. Check if alternative manufacturers offer equivalent performance metrics without requiring PCB re-layout.
