PDTA115EM,315 Discrete Semiconductor Products

The PDTA115EM,315 is a single, pre-biased bipolar junction transistor (BJT). It is used in various control, amplifying and switching applications.

The device is a monolithic integrated circuit that consists of a 300mA, 45V PNP bipolar transistor and two voltage-limiting diodes.

A bipolar transistor is a two-terminal, three-layer semiconductor device, which consists of a base, a collector and an emitter. It has both an N-type and a P-type semiconductor. It controls current flow between the collector and emitter terminals by regulating the voltage applied to the base.

In order to accurately determine the amount of current flowing through the transistor, the collector-to-emitter voltage must be precisely regulated.

In the PDTA115EM,315, this is accomplished through the use of two built-in voltage-limiting diodes. These diodes are connected in series between the base and emitter terminals, with one diode being connected to the base terminal and the other being connected to the emitter terminal.

In effect, a pre-bias is established by these diodes, which serve to regulate the amount of current flowing through the transistor. The applied voltage to the base must be greater than the rating of the device before it will begin to conduct current.

This makes the device ideal for use in circuits where precise control of current is required, such as amplifying and switching applications.

The PDTA115EM,315 is designed to be used in applications where a wide range of input voltages, from 3V to 45V, can be used. It is also suitable for low- and medium-voltage applications where low-current operation is required.

The device can be used in a variety of applications, including switch mode power supplies, DC, AC and pulse width modulated (PWM) power control, and switching circuits.

The PDTA115EM,315 is a versatile and reliable device, and is suitable for use in a wide range of industrial and consumer applications.
