BF423 is a PNP bipolar junction transistor manufactured in the TO-92 plastic package. This article is going to explain pinout, datasheet, equivalents, and other details about the BF423 transistor.
BF423
The BF423 transistor is a PNP bipolar junction transistor with a TO-92 plastic packaging. The transistor's pins are organized as follows: The transistor's first pin is the emitter, the second pin is the collector, and the third pin is the base.
The BF423 transistor's maximum collector current is 50mA, its maximum collector to emitter voltage is -250V, its maximum collector to base voltage is -250V, its minimum DC current gain is 50, its maximum collector dissipation is 830mW, and its maximum transition frequency is 60 MHz, though some manufacturers make it with a transition frequency of 100MHz (fT).
