Working Principle of 2DB1132R-13

The 2DB1132R-13 is a bipolar junction transistor (BJT). It operates by controlling the flow of current through its base and collector-emitter terminals. To turn on the transistor, current is applied to the base which then creates an inversion layer at this interface. This layer reduces the resistance between the base and emitter, allowing current to flow from the collector to the emitter.

When the transistor is off, no current flows from the base to the emitter and the transistor is an “open switch”. In order to turn the transistor off, the base voltage must be reduced to zero or a negative voltage. This causes the inversion layer to be eliminated, which then increases the resistance between the base and the emitter, effectively cutting off current from the collector.

The 2DB1132R-13 is a medium power NPN BJT and it is designed to work under the saturation region when used in switching applications. In this mode, it is operated by applying a voltage greater than the base-emitter voltage, Vce(sat), to the collector, which results in current flowing through the transistor. In this region of operation, the transistor is in its most efficient mode, allowing it to operate at high speeds with low power dissipation.

The 2DB1132R-13 is an ideal choice for switching applications as it can handle up to 1A current and has a collector breakdown voltage of 11.5 V. It is a versatile device that can be used in many applications, from low noise or linear audio amplifier circuits to high frequency applications for switching and impedance matching.
