ON Semiconductor BC857BDW1T1G - PNP Bipolar Transistor

The BC857BDW1T1G from ON Semiconductor is a PNP bipolar junction transistor (BJT) designed for general-purpose amplifier and switching applications. This semiconductor device is part of ON Semiconductor's extensive range of discrete transistors that offer high reliability and performance in compact package sizes.

Key Features:

• Transistor Polarity: PNP - This indicates that the primary charge carriers responsible for current flow are holes, making it suitable for use in the negative side of a circuit.
• Collector-Emitter Voltage (Vceo): 45V - The maximum voltage that can be safely applied from the collector to the emitter with the base open.
• Collector Current (Ic): 100mA - The maximum continuous current that can flow through the collector of the transistor.
• Power Dissipation (Pd): 250mW - The amount of power in milliwatts that the transistor can dissipate without damage.
• DC Current Gain (hFE): 220 to 475 - A measure of the amplification capability of the transistor, indicating how much the collector current is amplified for a given base current.
• Operating and Storage Junction Temperature Range: -55°C to +150°C - The range of temperatures over which the device can operate safely without compromising its functionality.
• Package / Case: SOT-323 - A small outline transistor package that is ideal for space-constrained applications.
