2N2484 Transistor Explained / Description:

2N2484 is a general purpose PNP transistor available in TO-18 package. It is designed to be used in general amplification and switching applications. The pin layout of the transistor is easy to understand. As you can see in the pinout image above the nearest pin from the tag is pin1, the nearest pin from pin1 is pin2 and the last one is pin3.

Looking at the absolute maximum ratings of the transistor the max collector-emitter voltage is -60V, max collector current is -100mA, max emitter-base voltage is -6V, collector dissipation is 360mW and max storage and operating temperature is from -65 °C to +150 °C.

Some electrical characteristics of the transistor include a transition frequency of 15MHz, DC current gain of 20 to 800 and its noise figure is from 3.0 to 10dB.

The transistor is also available in plastic TO-92 version having part number PN2484 so you can also use that one in the place of 2N2484.


Where We Can Use it & How to Use:

2N2484 is designed to be used in general purpose amplification and switching applications. When used as a switching it can drive load of upto -100mA which is suitable for driving small loads such relay switches, LEDs, ICs, small low current motors, power transistors, etc. Other than that it also has quite good features if you want to use it as an amplifier. It has a very good gain capability and noise figure which makes it ideal to use in audio amplification and pre-amplification applications. Moreover, it can also be used for any kind of low level signal amplification.

Safe Operating Guidelines:

Here are some guidelines for using the transistor safely.

  • Do not use it to its absolute maximum ratings and always stay 20% below from these ratings to get long term performance.
  • So according to the above guidelines the maximum collector-emitter voltage of the transistor is -60V but to stay 20% below we will not drive load of more than -48V.
  • The maximum collector current is -100mA but we will not drive load of more than -80mA.
  • The minimum and maximum operating temperature is -65 °C to +175 °C so make sure to store or use it between these temperature ranges.
