KSE13003-AS

Single Bipolar Transistors Overview

The KSE13003-AS is an NPN silicon planar epitaxial transistor manufactured by Fairchild Semiconductor, now part of onsemi. It is designed for high-voltage switching applications and operates in a single configuration. The device features a collector-emitter voltage (VCEO) of 400 V and a collector-base voltage (VCBO) of 700 V. It supports a maximum continuous DC collector current of 1.5 A with a power dissipation rating of 20 W in the TO-126 package. The gain-bandwidth product is 4 MHz, and it functions within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential obsolescence. Confirm RoHS compliance status as manufacturing processes may have evolved under onsemi ownership. Request original datasheets to validate electrical parameters against specific lot requirements. Ensure proper handling procedures are followed for through-hole components during assembly.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high voltage isolation and moderate current handling capabilities. The TO-126 package provides adequate heat dissipation for continuous operation. Consider the 4 MHz bandwidth limitation for frequency-dependent applications. Evaluate thermal management strategies given the 20 W power dissipation rating in standard mounting configurations.

Single Bipolar Transistors Part Context

This transistor belongs to the KSE13003 series of high-voltage NPN silicon transistors originally developed by Fairchild Semiconductor. The series is engineered for robust performance in demanding switching environments. Manufacturing has transitioned to onsemi following corporate acquisitions, maintaining technical specifications while updating packaging and labeling standards.

Single Bipolar Transistors Replacement Considerations

Equivalent parts include KSE13003ASTU and KSE13003H2ASTU from onsemi. Verify pinout compatibility and thermal resistance characteristics before substitution. Cross-reference datasheets to ensure matching voltage and current ratings for critical circuit applications.
