The Purdum-d3 with 135 application field and working principle is a type of transistor device that is classified under the Transistors - Bipolar (BJT) - Arrays, Pre-Biased category. It is composed of two transistors in a single package and is therefore often referred to as a double or dual transistor. It is rated at 135 volts, with a collector current of 0.5 milliamperes. It operates with a maximum collector power of 15 watts.

The most common application of this device is in audio amplifying circuits. It is suitable for use in low power audio applications as it has minimal distortion and low noise. It is also suitable for use in other types of circuit applications such as DC motor control, temperature sensing and power supply regulation. The Purdum-d3 with 135 application field and working principle is a low-cost, efficient, general-purpose device.

The Purdum-d3 with 135 application field and working principle utilizes a PNP and NPN transistor in a single package. This allows the device to drive loads up to 15 watts while only drawing 0.5 milliamperes of current. It also has a low thermal resistance and low quiescent current, making it suitable for applications that require low power consumption. The NPN transistor provides an output voltage at a low cost, and the PNP transistor provides an input voltage for signal gain, signal protection and rectification.

The Purdum-d3 with 135 application field and working principle has an active region terminal, and this has a fixed voltage on the collector of the PNP transistor. This voltage is called the bias and the device operates when the circuit voltage exceeds the bias voltage. As the circuit voltage is increased, the PNP transistor moves from off to saturation, allowing the NPN transistor to draw more current. This increases the load current and allows the device to produce higher voltages and currents.

This device also has two types of capacitor arrays: one for the collector/emitter path of the PNP transistor and the second for the base/emitter path of the NPN transistor. The capacitor array for the NPN transistor eliminates any parasitic capacitance between the base and emitter, further reducing noise levels. The capacitor array also acts as a dampener for the voltage swings in the circuit and prevents overshoot in the output voltage.

The Purdum-d3 with 135 application field and working principle is used to provide a low-cost, efficient, general-purpose amplifier. Its low cost, low thermal resistance and low quiescent current make it ideal for audio, motor control, and temperature sensing applications. Its dual transistor configuration and use of capacitor arrays help to reduce noise and eliminate overshooting in the output voltage, making it highly suitable for a variety of applications.
