CMPTA44 TR Discrete Semiconductor Products

The CMPTA44 is a single-chip bipolar transistor, which is ideal for varieties of electronic applications, mostly in the area of power management. It is easy to integrate with other components in a power supply, making it a perfect choice for a wide range of applications. The core transistor is a PNP type, which is well suited to power management applications.

The CMPTA44 transistor offers low voltage operation, high wafer yields and low power loss. It features a high voltage breakdown voltage of 700V, with an off-state leakage current of only 5µA. Furthermore, its high output current rating of 1A enables easy integration with other devices, making it suitable for various power management tasks. It is also compatible with many popular packages, including DIP and SIP formats.

In terms of design, CMPTA44 uses a three-layer structure, consisting of two collector base layers and one emitter layer. The collector and base layers are made up of n-type selenide layers, while the emitter layer is n+ type silicon. The three-layer structure allows for a cost-efficient power device with a high efficiency ratio. The CMPTA44 also promises low on-resistance, which means less power is wasted in the power path.

The CMPTA44 transistor works on the basis of a basic three layers of transistors. When an input voltage is applied to the base layer, it creates a potential barrier between the collector and emitter. This results in a passive current flow between the collector and emitter, allowing for a current amplification ratio of up to 200. Furthermore, the collector current is determined by the input current from the base, making it ideal for applications involving power amplification.

Thus, the CMPTA44 is an ideal choice for power management applications, offering a reliable and efficient power supply solution. It provides low voltage operation, high wafer yields, and low power loss. Furthermore, its high output current rating enables easy integration with other power management devices. Overall, the CMPTA44 is a great option for power-related applications.
