ZTX451

Single Bipolar Transistors Overview

The ZTX451 is an NPN silicon planar medium-power transistor manufactured by Diodes Incorporated. It features a maximum collector-emitter voltage (VCEO) of 60 V and supports a continuous collector current (IC) of 1 A. The device dissipates up to 1 W of power at 25°C ambient temperature. Key electrical characteristics include a collector-base breakdown voltage of 80 V, a transition frequency (fT) of 150 MHz, and a static forward current transfer ratio (hFE) ranging from 50 to 150 at IC = 150 mA and VCE = 10 V. It operates within a junction temperature range of -55°C to +200°C.

Single Bipolar Transistors Feature Summary

• Capable of handling 1 Amp continuous collector current with a 60 Volt collector-emitter voltage rating.
• Designed for high-temperature operation with a maximum junction temperature of 200°C.
• Constructed using NPN silicon planar technology in a molded plastic E-Line package.

Single Bipolar Transistors Applications

• General-purpose switching applications
• Linear amplifier circuits
• Driver stages for power loads

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Confirm that the component status aligns with project requirements, as certain variants may be marked Not Recommended for New Designs (NRND). Ensure compliance with RoHS and halogen-free specifications if required by the application environment.

Single Bipolar Transistors Selection Notes

Select the ZTX451 when a medium-power NPN transistor is required with a 60 V collector-emitter voltage rating and 1 A continuous current capability. Consider the 150 MHz transition frequency for moderate-speed switching or amplification tasks. Evaluate thermal management needs carefully, as the device supports a high operating temperature range up to 200°C.

Single Bipolar Transistors Part Context

The ZTX451 belongs to the ZTX450/ZTX451 family of NPN silicon planar medium-power transistors produced by Diodes Incorporated. These components are housed in the E-Line package, which is compatible with TO-92 footprints. The series is designed for general-purpose use, offering robust performance across a wide temperature range.

Single Bipolar Transistors Replacement Considerations

The ZTX450 is a related part within the same product family but has a lower collector-emitter voltage rating of 45 V compared to the ZTX451's 60 V rating. Verify voltage requirements before substituting between these two models.
