What are Bipolar Transistor Arrays?

Bipolar transistor arrays consist of two or more discrete transistors housed within a single package, which can be either electrically isolated or interconnected in some way internally. When the devices within the array have closely matched or complementary characteristics, their co-packaging helps reduce temperature variations between them during operation.

What are Pre-biased bipolar transistor arrays?

Pre-biased bipolar transistor arrays contain two or more bipolar transistors, each connected to resistors in a configuration that is typically beneficial. This usually includes one resistor between the emitter and base terminals of each transistor, along with another resistor linking each transistor's base terminal to a user-accessible pin on the device package.
