Ratasheet is the difference between using 2sd and 2n transistor. Will it burn my circuit? I’m trying to use them to amplify the power in my circuit, used to drive a mini cpu fan.

Are you sure that you want to delete this answer? The 2SD is a much beefier transistor than the 2N Fatasheet can handle 6-amps of current.

Surprisingly, CPU cooling fans can draw a good bit of current. One deluxe model I just looked at, needs 5-amps! The NTE, available at Fry’s would work. Unfortunately, I did not see a good substitute at RadioShack.

You can find data sheets produced datashert the manufactures for electrical devices and components here: The main difference between the two transistors is the power handling ability: The other datashewt to watch out for is power disipation: If the transistor is being used as a swtich this is usually no problem provided you dont exceed the maximum voltage or current ratings, since it either has a high voltage and a low zero current when datadheet switch is ‘off’, or a high current and a low ideally zero voltage when the switch is ‘on’.


But if you are using it as a ‘regulator’ or an amplifier, there can be large amounts of time when both the current and voltage across it are high, so the power dissipation is also high it will get hot! Related Questions Transistor confusion? Windows 7 64 bit vs 32bit and RAM usage confusion?
