Product Introduction

Overview

The FOD817BSD is a 4-pin dual in-line package (DIP) phototransistor optocoupler produced by onsemi. This device consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor. The FOD817 series is designed to provide high isolation and reliable performance in various applications.

The FOD817BSD specifically belongs to the FOD817B group, which has a current transfer ratio (CTR) range of 130% to 260%. This makes it suitable for applications requiring precise and reliable signal transfer across electrical isolation barriers.
