K827PH

Transistor, Photovoltaic Output Optoisolators Overview

The K827PH is a dual-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features a phototransistor output coupled to an infrared-emitting diode, providing electrical isolation with a rated voltage of 5000Vrms. The device operates with a DC input type and delivers a maximum output voltage of 70V per channel. Each channel supports a current output of 50mA, while the typical forward voltage for the input LED is 1.25V. Packaged in an 8-DIP configuration, this component ensures reliable signal transmission across isolated circuits.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific package variant and lead time directly with authorized distributors or the manufacturer before ordering. Confirm that the 8-DIP form factor matches your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your production standards. Cross-reference the datasheet revision date to confirm parameter stability against older versions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the K827PH when dual-channel isolation is required within a single package to save board space. Consider its 50mA output current capacity for driving moderate loads without additional amplification. Evaluate the 70V output voltage limit to ensure it exceeds the load requirements of your specific circuit application.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to Vishay's family of phototransistor optocouplers, which are designed for general-purpose isolation tasks. It shares architectural similarities with other models like the K817P and K847PH, differing primarily in the number of channels and pin configurations. These devices are widely used in applications demanding reliable electrical separation between low-voltage control logic and higher-voltage power stages.
