Feb 7, 0. V CBO V. Since the diode voltage of the base-emitter junction is generally about 0. I'd say you need a different transistor. If you're using the transistor purely as a switch, that means you want to saturate the output, or try to cause more current to flow from collector to emitter than your current limiting resistor will allow.

They have to be 5v right otherwise they dont open up all the way? I stand by my assesment of Shocwaver's requirements for a switching transistor also as in another thread on a similar subject.

V CBO V. It's the voltage given from the pins of a PC parallel port and this voltage changes depending on the load it's driving, so i guess the right question for the base should be: I'm quite ignorant with transistors so Datasheett need help to make this transistor to work as a switch because dtaasheet I'm hitting my head into the wall since friday.
What you typically want to do with a switching type application what you are doing with the IR LED is drive the transistor into saturation - that is basically just providing enough current into the base to cause the transistor to turn on completely with the current you are trying to control. This is how I envisioned the circuit: Datashfet assumes no liability for damage or losses occurring as a result of noncompliance with applicable laws and regulations.

V CEO V. Your name or email address: Then you can saturate the dafasheet however much you want e. If you are asked for more information, please supply it.
How are you measuring, 77ma at 1us - 5us? Ty for your attention. Everything runs on smoke, let the smoke out, it stops running Why do you need to pulse the LED?
If you need clarification, ask for help. Basically, though bipolar transistors are current controlled - the current into the base controls how much current flows between the collector and emitter see the portion of the data sheet that shows the Hfe so you need to provide a circuit that sources the required current or sinks depending on the transistor type NPN vs PNP sufficient base current to accomplish what you want.

Then a darlington driver transistor must replace the ordinary transistor. Dec 20, 11, 1, And you want mA. Mar 2, 3 0.
Unintended Usage include atomic energy control instruments, airplane or. May 16, 5, 8. Post them in the forum.
It is very unlikely that the resistor is bad - they typically get fat and brown when they open. What power supply are you using?
Mar 3, Please don't PM me with technical questions. I'm starting to think that this bjt is burned. Similar to what veritas has explained: What is the application?
Please use these products in this document in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled substances. If I swap the connections of the collector and emitter the current draw goes way up but then the led does funny things Pulsing But from what I read the negative side of the led connects to the collector and emitter goes to ground. Yes, my password is: Unintended Usage include atomic energy control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments, medical c2833, all types of safety devices, etc.
