Infineon BCR148WE6327: NPN Digital Transistor Array for Logic Interface Applications

In modern electronic design, efficiently interfacing low-power logic circuits with higher-current peripheral components is a common challenge. The Infineon BCR148WE6327 addresses this need by integrating two independent NPN digital transistors with monolithic bias resistors into a single, compact SOT-363 package. This device is engineered to simplify circuit design and reduce the component count in space-constrained applications.

Each transistor within the array includes built-in resistors: a 10 kΩ resistor connected to the base and a 10 kΩ resistor tied between the base and emitter. This integrated design eliminates the need for external discrete resistors, saving board space, lowering assembly costs, and enhancing overall circuit reliability. The BCR148WE6327 is particularly suited for interface and driver applications, such as controlling relays, LEDs, or lamps directly from the output of microcontrollers, logic gates (e.g., CMOS, NMOS, TTL), or other low-current sources.

Key performance characteristics include a collector current (IC) of up to 100 mA per transistor and a low saturation voltage, ensuring efficient switching even under load. The device operates with an input voltage compatible with standard logic levels, making it an ideal buffer between sensitive control logic and power components. Its dual-transistor configuration provides design flexibility, allowing engineers to use it for two independent channels or to combine them for more demanding tasks.

Housed in a very small SOT-363 package, the BCR148WE6327 is optimized for high-density PCB designs commonly found in consumer electronics, industrial automation, and automotive systems. Infineon's commitment to quality ensures high reliability and performance consistency, which is critical for mass production.
