The ON Semiconductor BC858BLT1G is a PNP bipolar junction transistor (BJT) designed for general-purpose amplifier and switching applications. This versatile transistor offers a balanced combination of features that make it suitable for a wide range of electronic circuits.

Key Features

• Transistor Polarity: PNP - This indicates that the majority charge carriers are holes, making it ideal for use in the negative side of the circuit.
• Collector-Emitter Voltage (Vceo): 30V - This is the maximum voltage that can be applied across the collector-emitter terminals without causing damage, ensuring reliability in a variety of applications.
• Collector Current (Ic): 100mA - The maximum continuous current that can flow through the collector of the transistor, suitable for small signal amplification.
• Power Dissipation (Pd): 250mW - The amount of power the transistor can dissipate through heat, which is sufficient for many low-power applications.
• DC Current Gain (hFE): 220 to 475 - This range indicates the amplification factor of the transistor, showing its efficiency in increasing the intensity of a signal.
• Package / Case: SOT-23-3 - A small and versatile surface-mount package that saves space on a printed circuit board (PCB).
