ZTX450

Single Bipolar Transistors Overview

The ZTX450 is an NPN silicon planar medium-power transistor manufactured by Diodes Incorporated. It features a collector-emitter sustaining voltage of 45V and supports a continuous collector current of 1A with a maximum power dissipation of 1W at 25°C ambient temperature. The device operates within a junction temperature range of -55°C to 200°C. Key electrical characteristics include a minimum static forward current transfer ratio (hFE) of 100 at 150mA, a transition frequency of 150MHz, and a collector-base breakdown voltage of 60V.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact packing quantity and reel size. Confirm that the component status matches the design requirement, as certain variants may be marked as Not Recommended for New Designs or Obsolete. Ensure compliance with environmental directives such as RoHS 3 and REACH requirements before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor with high thermal stability and a wide operating temperature range is required. The E-Line package provides a TO-92 compatible footprint suitable for standard through-hole PCB layouts. Consider the 150MHz transition frequency for moderate-speed switching or amplification tasks where low saturation voltage is beneficial for efficiency.

Single Bipolar Transistors Part Context

This part belongs to the ZTX450/ZTX451 series of NPN silicon planar medium-power transistors from Diodes Incorporated. The series includes variants with different voltage ratings, such as the ZTX451 which offers a higher collector-emitter voltage. These components are designed for general-purpose applications utilizing mature silicon planar technology.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the ZTX451, which shares identical mechanical and current specifications but offers a higher collector-emitter voltage rating of 60V compared to the ZTX450's 45V. Verify pinout compatibility and thermal dissipation requirements when substituting.
