KSP44TF

Single Bipolar Transistors Overview

The KSP44TF is an NPN silicon epitaxial planar transistor manufactured by onsemi, designed for high-voltage switching and amplification applications. It features a collector-emitter voltage (VCEO) of 400 V and a collector-base voltage (VCBO) of 500 V, with a maximum continuous collector current of 300 mA. The device operates in a TO-92-3 kinked lead package suitable for through-hole mounting. Key electrical specifications include a DC current gain (hFE) ranging from 50 to 200, a collector-emitter saturation voltage of 750 mV, and a power dissipation rating of 625 mW. The component supports a maximum operating temperature of +150°C.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability with 400 V collector-emitter and 500 V collector-base ratings
• Epitaxial silicon construction optimized for reliable high-voltage switching performance
• Standardized pinout configuration compatible with common through-hole PCB layouts

Single Bipolar Transistors Applications

• High-voltage switching circuits in telephone equipment
• Inverter driver stages in automotive electronics
• General-purpose amplifier circuits requiring high voltage tolerance

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TF' against the manufacturer's official datasheet to confirm packaging details such as reel or cut tape format. Ensure the procurement documentation explicitly states the TO-92-3 kinked lead package type. Cross-reference the RoHS compliance status directly with the latest environmental declaration provided by onsemi. Confirm that the supplier source is authorized to prevent counterfeit components.

Single Bipolar Transistors Selection Notes

Select this component when circuit designs require high voltage isolation with moderate current handling capabilities. The TO-92-3 package is appropriate for low-power through-hole implementations where space constraints are minimal. Consider the hFE range of 50 to 200 for biasing stability in amplifier designs. Evaluate thermal management requirements given the 625 mW power dissipation limit at elevated temperatures.

Single Bipolar Transistors Part Context

The KSP44TF belongs to the KSP44 series of high-voltage NPN transistors produced by onsemi. This series includes variants such as KSP44BU and KSP44TA, which share similar electrical characteristics but may differ in packaging or manufacturing lot specifications. The KSP44 series is widely utilized in legacy and modern electronic systems requiring robust high-voltage discrete semiconductor solutions.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the verified source material. Alternative components must be evaluated based on matching VCEO, VCBO, IC, and package dimensions. Verify pin compatibility if substituting with other high-voltage NPN transistors.
