Description and Introduction

300 V, 100 mA NPN high-voltage transistor The PXTA42 is a high-performance NPN bipolar junction transistor (BJT) designed for a variety of amplification and switching applications. Known for its reliability and efficiency, this component is widely used in industrial, automotive, and consumer electronics due to its robust electrical characteristics.  

With a collector-emitter voltage (VCE) rating of up to 300V and a continuous collector current (IC) of 500mA, the PXTA42 is well-suited for medium-power circuits. Its high current gain (hFE) ensures stable performance in signal amplification, while its fast switching capabilities make it ideal for pulse and digital applications.  

The transistor features low saturation voltage, enhancing energy efficiency in switching operations. Additionally, its compact SOT-89 package allows for easy integration into space-constrained designs without compromising thermal performance. The PXTA42 is also designed to handle high-temperature environments, making it a dependable choice for demanding applications.  

Engineers often select the PXTA42 for audio amplifiers, power management systems, and motor control circuits due to its balanced trade-off between speed, power handling, and thermal stability. When used within specified operating conditions, it delivers consistent performance with minimal signal distortion.  

For optimal results, proper heat dissipation and adherence to recommended biasing configurations are essential. The PXTA42 represents a versatile and durable solution for modern electronic designs requiring precision and durability.
