PACK OF 100 PIECES
The MPSA42 is an NPN bipolar junction transistor (BJT) packaged in a TO-92 casing. It is designed to handle a collector current of up to 500 milliamperes (mA) and withstand voltages up to 300 volts, with a current gain (hFE) of 40. This transistor is suitable for a variety of electronic applications, particularly in high-voltage circuits.
-
Transistor Type (NPN): As an NPN transistor, it requires a positive voltage at its base relative to the emitter for current to flow from the collector to the emitter. NPN transistors are commonly used for signal amplification and switching applications.
-
Package (TO-92): The TO-92 package is a widely used, compact, through-hole package, suitable for low-power applications. It is known for its ease of handling and integration into various electronic circuits.
-
Collector Current (500mA): With a maximum collector current of 500mA, the MPSA42 can control moderate levels of current, making it suitable for driving small to medium loads in electronic circuits.
-
Voltage Rating (300V): The voltage rating of 300 volts indicates the maximum voltage the MPSA42 can handle between its collector and emitter when the transistor is off. This high voltage rating makes it suitable for electronic circuits operating at higher voltages.
-
Current Gain (40hFE): The current gain, or hFE, of 40, indicates the transistor's efficiency in amplifying the input signal. A hFE of 40 means that the collector current is 40 times the base current.
-
Applications: The MPSA42 is versatile and can be used in high-voltage applications, such as power regulation, signal processing, and switching applications. It's also suitable for use in audio amplifiers, power supplies, and other electronic devices that require high voltage handling capabilities.
-
Features: NPN transistors like the MPSA42 are appreciated for their efficiency in controlling and amplifying electrical signals. They are fundamental components in both analog and digital electronic circuits.
The MPSA42 NPN transistor, with its 500mA collector current, 300V voltage rating, and hFE of 40 in a TO-92 package, is a reliable choice for electronic designs requiring a component capable of managing moderate power levels in high-voltage environments.
