BC640TA

The BC640TA is a small-signal NPN bipolar junction transistor (BJT) commonly used in amplifier and switching applications. Manufactured by various semiconductor companies, it features a low collector-emitter saturation voltage, making it suitable for low-power applications where minimizing power dissipation is crucial.With a maximum collector current rating of 1A, the BC640TA can handle moderate current loads. Its low noise figure makes it suitable for applications requiring low noise amplification, such as in audio circuits.The transistor is housed in a TO-92 package, which is a widely used through-hole package for transistors due to its ease of handling and mounting on circuit boards. The TO-92 package typically consists of three leads: the collector, base, and emitter, allowing for easy integration into electronic circuits.The BC640TA operates over a wide temperature range, typically from -65°C to 150°C, making it suitable for various environmental conditions. It has a moderate current gain (hFE) ranging from 100 to 630, providing flexibility in different circuit designs.
