BC807-40

BC807-40 Description

The BC807-40 from Diotec Semiconductor is a PNP bipolar junction transistor (BJT) designed for surface-mount applications, packaged in SOT23-3. With a collector-emitter breakdown voltage (Vceo) of 45V and a maximum collector current (Ic) of 800mA, this transistor is optimized for low-voltage, high-current switching and amplification in compact circuits. Its high transition frequency (100MHz) ensures efficient performance in high-frequency applications, while the low Vce saturation voltage (700mV @ 50mA, 500mA) minimizes power loss, enhancing energy efficiency.

BC807-40 Features

• High Current Handling: Supports up to 800mA Ic, making it suitable for power management and driver circuits.
• Low Saturation Voltage: 700mV @ 500mA ensures minimal power dissipation in switching applications.
• High DC Current Gain (hFE): 250 @ 100mA, 1V provides strong signal amplification with low input current requirements.
• Surface-Mount Design: SOT23-3 package enables space-efficient PCB layouts, ideal for portable and miniaturized electronics.
