What is a 2N2369 transistor.It's an npn switching transistor.
It is an npn power transistor
is zero
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
epitaxial
no
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
This mechanism is how a transistor works.
