BC550C Description

Short technical summary and product information.

The BC550C is a general-purpose NPN bipolar junction transistor manufactured by On Semiconductor. It features a collector-emitter voltage rating of 45V and a continuous collector current of 100mA, with a power dissipation of 625mW. The transistor offers a high DC current gain (hFE) of 420 minimum at 2mA collector current and 5V Vce, making it suitable for low-power amplification and switching applications. With a transition frequency of 250MHz, it can handle moderate frequency signals. The device is housed in a TO-92 (TO-226) through-hole package, which is widely used for discrete transistor designs. It operates over a junction temperature range of -55°C to 150°C, allowing use in a variety of environments. The BC550C is commonly used in audio preamplifiers, signal processing, and general switching circuits.
