Infineon BCR166E6327: High-Performance NPN Digital Transistor Array for Logic Interface Applications

The Infineon BCR166E6327 is a state-of-the-art NPN digital transistor array specifically engineered for logic interface applications requiring high performance and reliability. Designed to simplify circuit design and enhance system integration, this device integrates two independent NPN transistors with monolithic bias resistors, making it an ideal solution for interfacing between low-power microcontrollers or digital logic circuits and higher-power peripheral components.

A key feature of the BCR166E6327 is its built-in resistor network, which eliminates the need for external base resistors, thereby reducing component count, saving board space, and lowering overall system costs. Each transistor in the array includes a series base resistor and a base-emitter resistor, ensuring stable operation and improved noise immunity. This makes the device particularly suitable for inverter and driver circuits, where consistent performance and compact design are critical.

The transistor array operates with a collector current of up to 100 mA per channel, supporting a wide range of interface tasks such as driving relays, LEDs, or other small loads directly from digital signals. Its high DC current gain and low saturation voltage further enhance energy efficiency, making it suitable for battery-powered and portable devices. The device is housed in a SOT-363 surface-mount package, which is optimized for high-density PCB layouts and automated assembly processes.

With its robust ESD protection and broad operating temperature range, the BCR166E6327 ensures durability and reliability in demanding environments, including industrial control systems, automotive electronics, and consumer applications. Its ability to handle logic level conversion seamlessly, such as converting 3.3V or 5V signals to higher voltage or current outputs, underscores its versatility across multiple domains.
