Key Features:

• Transistor Polarity: PNP - This indicates that the primary charge carriers are holes, making it suitable for use in the negative side of circuits.
• Collector-Emitter Voltage (VCEO): 45V - The maximum voltage between the collector and emitter at which the transistor can operate safely.
• Collector Current (IC): -100mA - The maximum continuous current that can flow from the collector to the emitter.
• Power Dissipation (Pd): 500mW - The amount of power that the transistor can dissipate without exceeding its maximum operating temperature.
• DC Current Gain (hFE): 110 to 800 - A measure of the transistor's ability to amplify the input current.
• Operating Temperature Range: -55°C to +150°C - The range within which the transistor can operate without failure.
• Package / Case: TO-92-3 - A widely used through-hole package that is easy to handle and integrate into various circuit designs.
