PXTA42,115

Single Bipolar Transistors Overview

The PXTA42,115 is an NPN high-voltage transistor manufactured by Nexperia. It features a collector-emitter voltage (VCEO) of 300 V and a continuous collector current (IC) of 100 mA, with a peak collector current (ICM) of 200 mA. The device operates in a SOT89 surface-mounted plastic package with three leads. Key electrical characteristics include a DC current gain (hFE) minimum of 40 at IC = 30 mA and VCE = 10 V, and a transition frequency (fT) of 50 MHz. Total power dissipation is rated at 1.3 W at 25 °C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the component meets non-automotive qualification standards as indicated in the latest product data sheet revision. Ensure compatibility with standard SOT89 footprint dimensions during PCB layout planning to guarantee proper thermal performance and mechanical stability.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring high voltage isolation with moderate current capacity. The SOT89 package offers a compact solution for medium power applications. Consider the 300 V rating when designing for high-side switching or flyback topologies. Verify thermal management requirements against the specified junction-to-ambient resistance values for the intended operating environment.

Single Bipolar Transistors Part Context

This part belongs to Nexperia's high-voltage transistor portfolio, designed for robust performance in power conversion and lighting control systems. The PXTA42 serves as the NPN complement to the PXTA92 PNP transistor, allowing for complementary push-pull configurations in amplifier or driver stages within industrial and consumer electronics equipment.

Single Bipolar Transistors Replacement Considerations

The PXTA92 is the documented PNP complement. No other direct substitutes are listed in the official documentation.
