In summary, the transistor can be damaged by applying high voltages without any current limitation, which is most likely to occur in test 3. Test 2 may not necessarily damage the transistor if proper current limitation is provided. The value of Vbb used is unknown.

This is a homemade failure and i need to find out how is the transistor damaged after summited to these 3 tests:

test 1. base: pump in correct Vbb
emitter: grounded
collector: open

test 2. base: open
emitter: open
collector: pump in correct Vcc

test 3. base: pump in correct Vbb
emitter: grounded
collector: pump in correct Vcc

Can any1 explain to me how is the transistor damage by these tests.

Either of tests 1 and 3 could kill it if you just applied voltages without any respect to current levels. Test 3 is the most likely (almost garanteed to) kill it if nothing is provided to limit the current.

BTW. What was the value of Vbb that you used anyway?

How could test 2 possibly kill it?

I don't understand what is meant by "pump in correct [voltage]". So, I just assume that means connect to some supply voltage (with low output impedance as alluded to by uart).
 

FAQ: How is this transistor been killed?

How does a transistor get "killed" or damaged?

A transistor can be killed or damaged in a variety of ways, such as overvoltage, overcurrent, overheating, or physical damage. These can occur due to improper usage, manufacturing defects, or environmental factors.

What are the consequences of a transistor being killed?

The consequences of a transistor being killed depend on its role in a circuit. If the transistor is a critical component, its failure can result in the entire circuit not functioning properly. In other cases, it may cause a decrease in performance or complete failure of the device.

Can a killed transistor be repaired?

In most cases, a killed transistor cannot be repaired and will need to be replaced. Attempting to repair a damaged transistor may cause further damage to the device or the circuit it is a part of.

How can I prevent a transistor from getting killed?

To prevent a transistor from getting killed, it is important to follow the manufacturer's specifications and guidelines for usage. This includes ensuring the proper voltage and current levels are used, and that the transistor is not subjected to excessive heat or physical stress.

Is there a way to test if a transistor has been killed?

Yes, there are various methods to test if a transistor has been killed, such as using a multimeter or a transistor tester. These tests can help determine if the transistor is still functioning properly and if it needs to be replaced.
