DZT5401-13

The DZT5401-13 is a single bipolar junction transistor (BJT) that combines features of bipolar power transistors and multiple integrated circuit (IC) technologies. Capable of delivering up to 200mA of continuous current, the DZT5401-13 is able to represent an ideal choice for a wide range of applications, including linearized audio amplifiers and digital power amplifiers. This article will provide an overview of the power transistor’s main features as well as how it works.

Product Specifications

The DZT5401-13 utilizes a unique, field-effect transistor (FET) structure in which the majority carriers are injected near the base-collector junction. This structure offers several advantages, including improved thermal stability and increased current gain. Additionally, the DZT5401-13 makes use of internal increase biasing, which further increases current gain and ensures low power dissipation.The DZT5401-13 is available in standard TO-220 and SOT-91 packages, each of which offer similar sets of robust electrical characteristics. Maximum current gain and collector-to-emitter voltage are rated at 16A and 12V respectively. Switching times are quite good, with maximum rise and fall times of 10nS each. Lastly, it is capable of operating at ambient temperatures of up to 150°C.

Application Field

Thanks to its extremely robust electrical characteristics, the DZT5401-13 is used for a wide range of applications. Most commonly, it is used in linearized audio amplifiers, as it can handle high current levels without suffering from thermal runaway. Additionally, its fast switching times have made it popular in digital power amplifiers, allowing it to quickly and accurately switch between voltage and current levels.The DZT5401-13 is also popular as a power transistor in motor applications. Its high current output and robust construction make it suitable for long-term operation in high-end motor controllers. Furthermore, its integrated biasing ensures that back EMF will not cause any adverse effects on the device.

Working Principle

The working principle of the DZT5401-13 is identical to any other single bipolar junction transistor. It is controlled by a small current applied to the base-emitter junction, which in turn causes a much larger current to flow from the collector-emitter junction. It is this current flow that performs the actual work of the transistor.When using the DZT5401-13 for either switching or amplifier applications, a biasing voltage will need to be applied to the collector-emitter junction. This voltage acts as an offset, causing the transistor to turn on at a lower current level than would otherwise be required. Once the transistor has been activated, the signal to be amplified is applied to the base-emitter junction, which in turn causes an amplified current to flow between the collector and emitter terminals.

Conclusion

The DZT5401-13 is a powerful single bipolar junction transistor (BJT) that offers robust electrical characteristics and excellent thermal stability. As a result, it is suitable for a wide range of applications, including linearized audio amplifiers, digital power amplifiers, and motor controllers. Its working principle is the same as any other BJT, and it requires a biasing voltage to be applied before it can be used.
