FZT789ATA

Single Bipolar Transistors Overview

The FZT789ATA is a PNP medium power transistor manufactured by Diodes Incorporated, housed in an SOT-223 package. It supports a continuous collector current of -3 A and withstands collector-emitter voltages up to -25 V. The device features a collector-base breakdown voltage of -30 V and an emitter-base voltage rating of -7 V. Electrical characteristics include a DC current gain (hFE) ranging from 100 to 800 depending on the operating current, with a minimum of 300 at -10 mA. The saturation voltage is specified as low as -0.15 V at -1 A. Thermal performance includes a maximum power dissipation of 3.0 W under specific mounting conditions and an operating temperature range from -55 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix matches the required compliance level. The standard 'ATA' suffix denotes general industrial grade components, while the 'AQTA' suffix indicates AEC-Q101 qualified automotive-grade parts. Confirm the reel size and tape width specifications align with automated assembly equipment requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when high current drive capabilities are required alongside low saturation voltage characteristics. Ensure the thermal design accommodates the specified junction-to-ambient resistance values based on the intended PCB copper area. Verify that the base drive current is sufficient to maintain the transistor within the desired hFE range during operation.

Single Bipolar Transistors Part Context

This part belongs to the FZT789A series of medium power transistors designed for high-efficiency switching. It serves as the PNP counterpart to the FZT689B NPN transistor, allowing for complementary push-pull configurations. The SOT-223 package provides a balance between power handling capacity and surface-mount footprint efficiency.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the FZT689B as the complementary NPN type. No other direct substitute part numbers are documented in the official material.
