MPSA18 Transistor Explained / Description:

MPSA18 is a high gain and low noise transistor with quite interesting specifications. The maximum gain of the transistor is 1500 and the noise figure is only 1.5dB which makes it ideal to use in applications where the amplification of very small or low gain signal to high gain is an essential requirement. Moreover the low noise feature with 1.5dB noise figure cuts the noise from the signal that is amplified by the transistor. The 100MHz transition frequency also makes it ideal to use in RF circuits under 100MHz frequency. On the other hand this device can also be used as a switch to drive loads under 100mA.
