This particular transistor is part of their extensive range of discrete and analog semiconductors, tailored for a variety of applications across multiple industries.

Key Features

• Transistor Polarity: NPN - This indicates the type of charge carriers that constitute the current flow through the transistor. NPN transistors are controlled by the movement of electrons.
• Collector-Emitter Voltage (V<sub>CEO): 45V - This is the maximum voltage that can be safely applied across the collector-emitter terminals without risking damage to the transistor.
• Collector Current (I<sub>C): 500mA - This is the maximum continuous current that can flow through the collector of the transistor.
• DC Current Gain (h<sub>FE): 250 to 600 - This is a measure of the transistor's ability to amplify the current, indicating how much the input current to the base is amplified in the collector circuit.
• Power Dissipation (P<sub>D): 500mW - The amount of power that can be dissipated by the transistor in the form of heat without causing damage.
• Operating and Storage Junction Temperature Range: -55°C to +150°C - This specifies the range of temperatures within which the transistor can safely operate and be stored.
• Package / Case: SOT-23-3 - A small and efficient surface-mount package that is commonly used for discrete semiconductors.
• RoHS Compliant: Yes - The product is compliant with the Restriction of Hazardous Substances Directive, which restricts the use of certain hazardous materials in electronic equipment.
