May 17, 2024 · I provided a very simple NPN transistor set up and hFE values as shown below. 2N2222 datasheet I am trying to calculate parameters such as base current, collector current, …

Nov 3, 2022 · According to the datasheet, a 2N2222 can handle VCE(max) V C E (m a x) up to 40 V 40 V. However, in the lab, I've seen different 2N2222s fail (get turned on) and burn with the …

I've been fiddling around with a brushed DC motor, a 2N2222 and an arduino's PWM to get different speeds out of my motor. Now, based on a video tutorial I watched on youtube, It was …

Apr 26, 2025 · 2 2N2222 NPN transistor has hfe values given in the picture 1. As for the circuit given in picture 2, I set Ic= 4.2 mA and Vce=7.5 V arbitrarily. For simplicity I assume Ic=Ie. I …

I'm a beginner to electronics. I just started to test transistors, but I've some doubts. I've used this schematic to test a NPN 2N2222: My questions: 1 - How much Voltage or Amps should the ...

I'm having trouble every time I need to find a component with LTspice. Normally I manage to find what I need. but not for the current component. I need a 2N2222 transistor. I've tried to enter …

Dec 31, 2020 · I used 2n2222 in this circuit - works normally. Even if hfe is a bit different in datasheet, there is huge variation of hfe between individual devices

Feb 10, 2015 · and I have no idea (Google has not proven helpful) what is the big difference between a 2n2222 and 2n2222a Transistor. I am using these for logic gates (for now just basic …

Aug 20, 2023 · If you are using the metal ones, start with PN2222A and edit the footprint to TO18-3 and the value to 2N2222 I tend to agree that's the way it should be, but you can buy …
