PUMD2,125

The PUMD2,125 is a special type of transistor array, known as pre-biased transistors. It has multiple uses and applications, as well as an interesting working principle. This article will explore the details of this device, focusing on its application field and working principle.

The PUMD2,125 device is an array of two transistors, otherwise known as a “dual”. It is an NPN-PNP type transistors array. This means that it is composed of two different types of transistors, each with its own type of collector-emitter voltage or “breakdown voltage”, usually between 7 and 20 volts, depending on the manufacturer. It has several configuration options, and can be used in various applications.

The PUMD2,125 is primarily used for load-side control applications. It can be used in conjunction with a variety of devices, such as switches, relays, and loads. Its output signals can be configured to trigger various devices, as well as provide signals for current sensing and control systems. Its unique pre-biased configuration allows for greater reliability, as the device does not require a dedicated load to remain biased in the desired state.

The working principle of the PUMD2,125 is relatively simple. It is designed to provide amplification with the two transistors. When a voltage is applied to the input of the device, the voltage is split between the two transistors, with the larger share going to the NPN. This creates a current in the collector-emitter circuit of the NPN transistor, which is then amplified by the PNP transistor. This amplified current can then be used to trigger devices or send current sensing signals.

In addition to its primary application field, the PUMD2,125 can also be used for voltage sensing and reference voltage generation, as well as for temperature sensing and even for creating a “shift register”. All these applications are possible thanks to its unique pre-biased configuration, which allows the device to work with a variety of devices and configurations.

The PUMD2,125 is a versatile device, with a wide range of applications and uses. Its unique pre-biased configuration and working principle allows for reliable operation, and great flexibility in terms of configuration and use. This makes it an ideal choice for many load-side control applications.
