SUMMARY

The BC238 transistor has an absolute maximum collector current (Ic) rating of 100mA, contrary to the initial assumption of 10mA. Exceeding this rating can damage the transistor, as it is crucial to operate within the Safe Operating Area (SOA) to prevent thermal failure. Users should also consider the maximum collector dissipation of 500mW for the TO92 package and avoid simultaneous maximum current and voltage conditions to ensure device longevity.

PREREQUISITES
  • Understanding of transistor specifications and ratings
  • Familiarity with reading electronic component datasheets
  • Knowledge of thermal management in electronic circuits
  • Basic concepts of Safe Operating Area (SOA) for transistors
NEXT STEPS
  • Research the Safe Operating Area (SOA) for various transistors
  • Learn about thermal resistance and its impact on transistor performance
  • Explore the Fairchild datasheet for the BC238 for detailed specifications
  • Investigate alternative transistors with higher current ratings for specific applications
USEFUL FOR

Electronics enthusiasts, hobbyists, and engineers who are learning to read and interpret transistor datasheets, particularly those working with the BC238 transistor.

Hi , Everyone
I'm learning how to read datasheets , amd i have a question about this .
In the datasheet of the transistor BC238 , in the Absolute Maximum Ratings the Ic = 10mA
Does That mean that i can't get an Ic output = 1000mA .
Thanks .

If the datasheet says absolute max is 10mA (which is pretty small, BTW, must be a dinky transistor!), then no, you can't pull more than that through it. In fact, you should generally stay away from the absolute max ratings anyway -- too close to damaging the device. You should instead look at the Safe Operating Area plot in the datasheet, and be sure to look at the thermal resistance for various mounting options, to be sure that you're keeping the transistor running reasonably cool in power applications.
 
Thanks a lot Man .
But My Datasheet doesn't have a Safe Operating Area plot , and don't ask me How !
I'll Try to get another one
Thanks again
 
According to the Fairchild datasheet, Ic(max) is 100mA for the BC238.

Maximum collector dissipation is 500mW, which is reasonable in a TO92 package.

The other thing to bear in mind is that you can't have maximum current & maximum voltage at the same time... that is outside the "Safe Operating Area" and will let the magic smoke out of the device.
 
ya zeitghost
you are right , It's 100mA
I must have been mixed it with another .
Thanks .
