Single Bipolar Transistors Overview

The KST4401 is an NPN epitaxial silicon switching transistor manufactured by onsemi, formerly Fairchild Semiconductor. It is housed in a SOT-23 surface-mount package with three pins. The device supports a maximum collector current of 600 mA and a collector-emitter voltage of 40 V. Key electrical parameters include a collector-base breakdown voltage of 60 V, an emitter-base breakdown voltage of 6 V, and a DC current gain ranging from 20 to 300 depending on the operating point. The transition frequency is rated at 250 MHz, with a maximum power dissipation of 350 mW.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the official onsemi database to ensure correct tape-and-reel or cut-tape availability. Confirm that the component meets RoHS compliance requirements for your target market. Check for any legacy part number changes resulting from the Fairchild Semiconductor integration into onsemi's product portfolio.

Single Bipolar Transistors Selection Notes

Select this component when a small-form-factor NPN transistor is required for low-voltage switching tasks. Ensure the application current remains within the 600 mA continuous limit and the power dissipation does not exceed 350 mW without adequate thermal management. Consider the 250 MHz bandwidth if high-speed signal processing is involved.

Single Bipolar Transistors Part Context

This component belongs to the family of small-signal NPN transistors designed for efficient space-constrained designs. It serves as a standard replacement for legacy through-hole equivalents in modern printed circuit board layouts. The device is widely used in consumer electronics and industrial control systems requiring reliable low-power switching capabilities.
