2014年5月14日 · The most commonly used transistor switch is the PNP variety shown in Figure 1. The secret to making a transistor switch work properly is to get the transistor in a saturation …

2008年10月1日 · I stumbled upon this site a few days ago while I was looking for information on the 2n3906 transistor, and transistors in general. That said, I'd like to pose a question, in …

2013年4月27日 · A "high" output connected to Vcc, whether with a resistor, a transistor, or a piece of wire, will not accept current from Vcc because, 1) there is no voltage difference and, 2) the …

2016年2月4日 · If changing the base resistor changes the current through the magnet, then the transistor is not saturated and will burn up. At 100 mA, each volt across the 3906 is 100 mW of …

2008年4月21日 · The 2M3904 transistor is too weak to drive the motor. A base resistor with only 4mA in it (1.8k) doesn't provide any transistor with enough base current to saturate properly …

2020年2月22日 · A 2N3904 is an NPN transistor and used commonly to switch the low side of a load. The emitter goes to ground, the collector goes to the negative side of the load. And the …

2020年1月21日 · This circuit (in part) (below) is operating at 12 volts. R2 is a square wave input (high / low). The 3906 is getting warm. After a minute of operation I'm measuring a case …

2018年6月30日 · 2N3906 is a PNP transistor. And that is not how you would wire it. Emitter to +5V, collector to + power on the board. Base, through a resistor to the output pin, - power on …

2011年4月5日 · hey all, im new to the forums here but i've been dabbling with electronics for as long as i can remember. anyways everyone seems really helpful on here so here goes: i have …

2008年12月30日 · Question on testing transistor 3904: Analog & Mixed-Signal Design: 7: Sep 29, 2015: 3904 not inverting a square wave input at base: Digital Design: 3: May 28, 2013: T: …
