FZT649TC

Single Bipolar Transistors Overview

The FZT649TC is an NPN high-performance transistor manufactured by Diodes Incorporated, housed in a surface-mount SOT223 package. It supports a continuous collector current of 3A and a peak pulse current of 8A. The device features a collector-emitter breakdown voltage (BVCEO) of 25V and a collector-base breakdown voltage (BVCBO) of 35V. Electrical characteristics include a low saturation voltage of less than 300mV at 1A input. Thermal management allows for power dissipation up to 2W on standard PCBs and 3W with enhanced copper areas, operating within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TC against official Diodes documentation to confirm the reel size and quantity per reel. Ensure that the selected component meets the required environmental standards, including RoHS compliance and moisture sensitivity levels. Cross-reference the datasheet revision number to guarantee access to the most current electrical parameters and mechanical dimensions before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high current handling in a compact surface-mount form factor. Evaluate the thermal resistance values based on the intended PCB copper area, as power dissipation capabilities vary significantly between standard and enhanced layouts. Consider the complementary FZT749 if a matched pair is necessary for efficient push-pull configurations or bridge driver topologies.

Single Bipolar Transistors Part Context

This part belongs to the FZT series of medium power transistors produced by Diodes Incorporated. The series utilizes silicon planar epitaxial technology optimized for robust performance in demanding environments. The FZT649 specifically targets applications needing reliable switching with minimal voltage drop, serving as a key alternative to traditional through-hole packages while maintaining comparable electrical specifications.

Single Bipolar Transistors Replacement Considerations

The FZT749 serves as the direct complementary PNP counterpart within the same product family. Verify pinout compatibility and thermal characteristics when substituting components in existing designs. Consult official manufacturer resources for any updated equivalents or cross-references that may have been released after the current datasheet publication.
