BUL903ED is an isolation amplifier and a bilateral switch component series manufactured by ISSI that are fabricated using high-voltage Bipolar-Junction Transistors (BJTs). These devices are designed to provide high-speed, high-voltage isolation and bidirectional switching applications in industrial, automotive, and avionic systems.

The BUL903ED series offers an isolation voltage (Vi) of 4000V, an IEC specified maximum collector-emitter voltage (Vce) of 57V, and a maximum collector current (Ic) of 0.6A. These devices are rated for 0.04W dissipation and have a temperature range from -55°C to +125°C. This temperature rating makes them suitable for working in a variety of industrial and automotive applications.

The BUL903ED can be used for high-speed, high-voltage/current switching and isolation applications, such as automotive junction boxes, in telecommunication systems, and in heavy industry. These devices are also well-suited for use in avionic systems, motor control circuits, and automotive electronics.

The main working principle of the BUL903ED is based on the regulated surge blocking bipolar transistor, commonly known as the "Three-Terminal Regulator"—a bipolar transistor configured as a transistor switch. In this configuration, the NPN core transistor device is series-connected with an output current source, and can be used to either block or conduct the input current.

The BUL903ED has two main characteristics: Bidirectional and High-Isolation. Bidirectional switching refers to the ability of the transistor to switch both transistors at the same time, either on or off. This feature allows for flexibility and dependability in switching applications. The High-Isolation feature provides the ability for the device to block the output of one transistor from another, resulting in enhanced immunity to power-supply related noise and ground-bounce issues in sensitive circuits.

In addition, this device also features Integrated Transistor Protection (ITP) that provides superior protection against destructive and potentially hazardous conditions resulting from overvoltage and excessive temperatures, which can cause long-term device failures. The ITP feature also ensures that the transistor can withstand the high-voltage and high-current surges encountered in industrial and automotive power systems.

The BUL903ED can be used in a variety of industrial, automotive, and avionic applications. It is ideal for high-speed, high-voltage/current switching and isolation applications. Furthermore, its Integrated Transistor Protection and bidirectional switching capabilities make it a reliable, versatile, and safe option for use in a variety of industrial and automotive systems.
