The PN3645_D75Z is one of a group of different single bipolar transistors, with different characteristics and performance. By understanding the basic principles behind the PN3645_D75Z, you can get the most out of your application.

Function

A PN3645_D75Z bipolar transistor is a three-terminal device, consisting of a base, collector, and emitter. When current is applied to the base, it controls the flow of current between the collector and emitter. This current flow creates a voltage drop across the emitter-collector junction. This voltage drop is then used to amplify or switch an external voltage.

Formula for Calculating Collector Current

The collector current that flows from the PN3645_D75Z transistor is a function of the voltage drops at the base and the collector-emitter junction. To calculate the collector current, the following formula can be used:

Collector current (Ic) = β x (Vbe/Vce)²

Where: β is the DC current gain of the PN3645_D75Z, VBE is the base emitter voltage, and VCE is the collector emitter voltage.
