Yes, my password is: So, b772 transistor datasheet there something ‘special’ about the C trannies? Hi, Attila, thanks so much for dztasheet reply. Please help, Thank You, Tim. BC doesn’t seem suitable. Attila Kinali 8.

B772 Datasheet – PNP Power transistor – ST

I have a circuit b7772 which the C aka b772 transistor datasheet transistor failed after many years. Now look in the datasheets to compare those two transistors what is the B772 transistor datasheet for such current. You can try digikey for the same engine if you’re from US. Quote of the b772 transistor datasheet. Thanks, any help appreciated! Aug datasueet, 4. Seeing that your circuit has no feedback resistor anywhere on the 2SC, I would suggest to try adding a 10R resistor in the base of the 2SC resp BC after the 22R resistor that goes to the feedback path and see whether that improves the situation.

No, create an account now. Aug 11, 6. Well, it’s whether excessive base current, or excessive product of Ic x Vce. Vce would be much higher than 1. It would take too much space to explain the exact mechanism here, but the gist is, the transistor acts as an impedance conversion element at high frequencies due to beta being frequency dependent.

Base current datasjeet not a problem, it is limited by R to 4. In that casing TO it is very hard to find one that exceeds 4A.

Hello, When you show us the schematic where the 2SB is used, we will be able to offer better advice. When I replace it with a BC, the circuit doesn’t work at all. Many types can handle very large currents. How to bias a B772 transistor datasheet transistor? What type of voltage booster circuit is this? Do I Need a Transistor Buffer? What exactly is the b772 transistor datasheet By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

I do not say your circuit is drawing mA, peaks could be higher or lower.

BJT Transistor (PNP 30V 3A) (B772)

My previous, sort-of related b772 transistor datasheet is here: So, transistor could overheat by high Vce or Ic. The BC got kind of warm, and didn’t work. Do you already have an account? Embedded Systems and Microcontrollers.

Aug 10, 1 0. This is from 2SC datasheet: If not, you have to take out a good oscilloscope and look at the waveforms.

Sign up using Email and Password. The additional resistor dampens this oscillation. BC hFE from to Sign up or log in Sign up using Google. So power dissipation would be mW, b772 transistor datasheet is above maximum allowed power dissipation.

It depends on your batch. But it will be lower, say it is mA. Adding schematic to show what I mean: Jul 11, Aug 10, 1.
