TLP285(TP,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP285(TP,F) is a single-channel optoisolator featuring a transistor output, manufactured by Toshiba Semiconductor and Storage. It provides electrical isolation with a maximum voltage rating of 3750Vrms or 5000Vrms depending on specific configuration variants. The device utilizes a gallium arsenide infrared emitting diode coupled to a phototransistor within a compact 4-SOP (SOP4) surface-mount package. Key electrical parameters include a collector-emitter saturation voltage (Vce Saturation) of up to 400mV and an operating temperature range spanning from -55°C to 110°C. The component is designed for DC input applications.
