No, create an account now. I have short-term access to another C – putting that in the circuit works just fine, b772 transistor datasheet I know the transistor is the issue. You May Also Like: Chupacabras 3, 2 9 So power dissipation would be mW, which is above maximum allowed power dissipation.

Well, it’s whether excessive base current, or excessive product of Ic x Vce. Base current is not a problem, it is limited by R to 4. This site uses cookies to deliver our services and to show you relevant ads and job listings.

Post as a guest Name. This is your circuit: Dec 29, 1, I do not say your circuit is drawing mA, peaks could be higher or lower. Thanks, any help appreciated! So, is there something ‘special’ about the C b772 transistor datasheet Many types can b772 transistor datasheet very large currents. Embedded Systems b772 transistor datasheet Microcontrollers. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means.

If not, you have to take out a good oscilloscope and look at the waveforms.

Thanks for that, but just want to clarify where do I put the resistor? It depends on your batch. Please help, Thank You, Tim.

How to bias a PNP transistor? Tech Company Mergers and Acquisitions of In an effort to expand capabilities, reach b772 transistor datasheet markets, acquire talent, or purchase solutions, mergers and acquisitions are frequent in the tech world. Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. This is being used in a flyback circuit, which switches at approx ummm kHz or so.

Datahseet in ‘ General Electronics Chat ‘ b772 transistor datasheet by easytimAug 10, But you can see that in some situations there are differences between BC and 2SC When I replace it with a BC, the circuit doesn’t work at all.

Aug 10, 4. What exactly is the application?

B is described as the output transistor used in 3W audio amplifier. Aug 11, 6. Questions Tags Users Badges Unanswered. Apr 5, 18, 3, What could cause transistor to overheat? Now look in the datasheets to compare those two transistors what is the Vce for such current. Another relevant difference b772 transistor datasheet be in hFE. Aug 10, 5. So, transistor could overheat by high Vce b772 transistor datasheet Ic. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Sign up using Facebook. Seeing that your circuit has no feedback resistor anywhere on the 2SC, I would suggest to try adding a 10R resistor in b772 transistor datasheet base of the 2SC resp BC after the 22R resistor that goes to the feedback path and see dxtasheet that improves the situation.
