AI Thread Summary
The BC238 transistor has an absolute maximum collector current (Ic) rating of 10mA, indicating that exceeding this limit, such as attempting to draw 1000mA, could damage the device. Users are advised to avoid operating near absolute maximum ratings and to consult the Safe Operating Area (SOA) for safe usage, although some datasheets may not include this information. The Fairchild datasheet specifies a maximum Ic of 100mA, with a maximum collector dissipation of 500mW for the TO92 package. It's important to note that maximum current and maximum voltage cannot be applied simultaneously, as this exceeds the SOA and risks damaging the transistor. Understanding these specifications is crucial for safe and effective transistor application.

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 Alot 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 .
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
