DiodesZetex PNP Bipolar Transistor 1 A, 30 V, 4-Pin SOT-223 Package FZT549TA

DiodesZetex FZT549TA is a general-purpose PNP bipolar transistor designed for both amplification and switching applications in industrial, automotive, and electronic circuits. It offers a maximum DC collector current of 1 ampere and a maximum collector emitter voltage of 30 volts, making it well-suited for medium power electronics applications.

The transistor features a 4-pin SOT-223 surface mount package that allows for efficient heat dissipation and compact board layouts. The maximum power dissipation rating is 2 watts, enabling it to handle moderate power loads reliably under continuous operation.

Its minimum DC current gain (hFE) of 30 supports sufficient amplification, and the high transition frequency of 100 MHz makes it suitable for high-speed switching circuits. The device operates safely within -55°C to 150°C, making it ideal for industrial environments that require wide temperature tolerance.

Compliance with the automotive standard AEC-Q101 further qualifies the FZT549TA for use in automotive electronics, including sensor circuits, signal switches, and power management modules.

Key mechanical dimensions include a 6.55 mm length, 7.1 mm width, and 1.65 mm height, supporting compact PCB designs. This transistor is manufactured in Germany, assuring consistent quality and reliability for demanding applications.
