It means it has a high collector therefore it is mostly used in that circuits where low to medium current is required. It works on high transition frequency value MHz with delay time Reviews: 6.  · 2N is the most common NPN bipolar junction transistor available in the market. It can be used for amplification of analog signals as well as switching applications. It can be used for amplification of analog signals as well as switching applications.

2N provides continuous dc collector current is mA. It means it has a high collector therefore it is mostly used in that circuits where low to medium current is required. It works on high transition frequency value MHz with delay time 10ns, rise time 25ms, storage time ms and fall time 60ms. I calculated the LED resistance as follows: (assuming V forward voltage and 20mA forward current, for ultra bright LED) R1 = (( – V) / 20mA) = 20ohm. I know the resistor R2 on the emitter leg of the 2N is required, but I am not totally sure if I calculated it correctly: R2 = ((5 – – V) / 20mA) = 50ohm. This is where power transfers to the LED through extremely fast switching action of the transistor, and was impressed with the performance of the old 2N transistor. It was a general-purpose transistor in a TO package, which looked like a metal can. I remember using it to drive LEDs and relays back when I was a whippersnapper. Driver Transistor.

An LED driver is an electronic circuit that utilises a transistor to switch power to an LED. Usually, the signal from a microcontroller, or logic gate.
