BC807-25

BC807-25 Description

The BC807-25 from Micro Commercial Components (MCC) is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Encased in a compact 3-pin SOT-23 package, it offers a maximum collector-emitter voltage (V_CE) of 45V and a collector current (I_C) rating of 0.5A, making it suitable for low-to-medium power circuits. With a power dissipation capability of 300mW and an operating temperature range up to 150°C, this transistor ensures reliable performance in demanding environments. Its high transition frequency (100MHz min) and low saturation voltages (V_CE(sat) = 0.7V @ 500mA, V_BE(sat) = 1.2V @ 500mA) enhance efficiency in switching applications.
