BC549BTA Description

Short technical summary and product information.

The BC549BTA is an NPN bipolar junction transistor manufactured by On Semiconductor. It features a collector-emitter voltage rating of 30V and a collector current rating of 100mA, with a maximum power dissipation of 500mW. The device offers a minimum DC current gain of 200 at 2mA collector current and 5V collector-emitter voltage, and a transition frequency of 300MHz, making it suitable for general-purpose amplification and low-frequency switching applications. The transistor is housed in a through-hole TO-92-3 package, with an operating junction temperature up to 150°C. RoHS3 compliance is reported but unverified.
