Single Bipolar Transistors datasheet and documents for 2N4401

2N4401

Single Bipolar Transistors Overview

The Diotec Semiconductor 2N4401 is a general-purpose NPN silicon epitaxial planar transistor housed in a TO-92 package. It supports a maximum collector current of 600 mA and a collector-emitter voltage of 40 V. The device features a DC current gain (hFE) ranging from 20 to 300, with a transition frequency of 250 MHz. Power dissipation is rated at 250 mW under standard conditions, extending to 625 mW when mounted on a PCB with 3 mm² copper pads. Operating temperatures range from -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. Standard units are commercial grade. Suffixes -Q indicate AEC-Q101 compliance, while -AQ indicates AEC-Q101 qualification. Confirm packaging preferences, as standard supply uses an ammo pack with 2.54 mm pitch, while bulk packaging requires a specific request and suffix.

Single Bipolar Transistors Selection Notes

Select this component for low-power NPN switching and amplification tasks requiring moderate current handling. Ensure thermal management aligns with the 250 mW ambient rating or utilize PCB copper pads to achieve the 625 mW limit. Verify that the required hFE range fits within the specified 20 to 300 limits for the target operating current.

Single Bipolar Transistors Part Context

This component belongs to the standard 2N4401 family of small-signal NPN transistors. It serves as a common alternative to similar devices like the 2N3904 but offers higher current capabilities. The complementary PNP counterpart recommended by the manufacturer is the 2N4403.
