PXTA42 Description

Short technical summary and product information.

The Nexperia PXTA42 is an NPN high-voltage transistor designed for demanding applications requiring robust performance. It offers a high collector-emitter voltage of 300 V and a continuous collector current of 100 mA, with a peak capability of 200 mA.

This transistor is suitable for applications such as electronic ballasts for fluorescent lighting, LED drivers for chain modules, High Intensity Discharge (HID) front lighting, wired telecom hook switches, and Switch Mode Power Supplies (SMPS).

The PXTA42 is packaged in a medium power, flat lead SOT89 (SC-62) surface-mounted device (SMD) plastic package. Its thermal characteristics include a junction-to-ambient thermal resistance of 96 K/W and a junction-to-solder point thermal resistance of 16 K/W, with a maximum total power dissipation of 1.3 W at 25°C ambient temperature.

Key electrical characteristics include a minimum DC current gain (hFE) of 40 at 10V and 30mA, and low cut-off currents (ICBO and IEBO) of 100 nA.
