ISLT1009

Transistor, Photovoltaic Output Optoisolators Overview

The ISLT1009 is a single-channel transistor output optocoupler manufactured by Isocom Components. It features an infrared emitting diode coupled to an NPN phototransistor within a compact SOP-4 surface-mount package. The device provides electrical isolation between input and output circuits, characterized by a high current transfer ratio range of 200% to 400%. Key electrical specifications include a maximum collector-emitter voltage of 70 V, a forward current rating of 60 mA, and a reverse voltage capability of 6 V. The unit operates reliably across a temperature range from -55°C to +100°C, with typical switching times of 3 µs rise and 4.7 µs fall.
