PC357NJ0000F

Transistor, Photovoltaic Output Optoisolators Overview

The PC357NJ0000F series comprises single-channel transistor output optocouplers featuring an infrared emitting diode optically coupled to a phototransistor. Packaged in a 4-pin Mini-flat surface-mount configuration, these devices provide an isolation voltage of 3.75kVrms. The collector-emitter breakdown voltage is rated at 80V, with a maximum forward current of 50mA and a typical forward voltage of 1.2V to 1.4V. Current transfer ratios range from 50% to 600% depending on the specific suffix variant, measured at an input current of 5mA. Operating temperatures span from -30°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific CTR ranking suffix (e.g., N1, N2, N6) required for your application, as performance varies significantly across the series. Confirm RoHS compliance status and UL recognition requirements during sourcing. Ensure the selected variant matches the desired current transfer ratio specifications to avoid circuit redesign.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select variants based on required current transfer ratio precision; lower suffix numbers typically indicate tighter or higher CTR ranges. Consider thermal management capabilities within the Mini-flat package when designing for high ambient temperatures. Verify that the 80V collector-emitter voltage rating exceeds the maximum load voltage in the target circuit application.
