2N4854U

Bipolar Transistor Arrays Overview

The Microchip Technology 2N4854U is a dual small-signal bipolar junction transistor (BJT) configured in an NPN/PNP complementary arrangement. It utilizes silicon technology and is housed in the U-6 surface-mount package. The device supports a maximum DC collector current of 600 mA and operates with a collector-emitter voltage (VCEO) of 40 V, a collector-base voltage (VCBO) of 60 V, and an emitter-base voltage (VEBO) of 5 V. Power dissipation is rated at 600 mW. The component functions within a temperature range from -65°C to +200°C. DC current gain (hFE) ranges from a minimum of 35 at 100 µA/10 V to a maximum of 300 at 150 mA/10 V, with a collector-emitter saturation voltage of 400 mV.

Bipolar Transistor Arrays Procurement Notes

Verify the specific suffix 'U' against the manufacturer's official datasheet to confirm the U-6 surface-mount package designation. Ensure that the required operating temperature range and power dissipation limits align with the system thermal design specifications before finalizing procurement.

Bipolar Transistor Arrays Selection Notes

Select this component when a dual NPN/PNP BJT pair is required in a surface-mount format. Compare the 600 mA current rating and 40 V voltage limits against circuit requirements. Consider the U-6 package dimensions for PCB layout constraints and verify compatibility with reflow soldering profiles suitable for the specified temperature range.

Bipolar Transistor Arrays Part Context

The 2N4854U belongs to the 2N4854 series of dual small-signal transistors manufactured by Microchip Technology. This series includes through-hole variants such as the TO-78-6 packaged 2N4854 and military-grade versions like the JAN2N4854U/TR. The U-6 suffix specifically denotes the surface-mount variant within this product family.

Bipolar Transistor Arrays Replacement Considerations

Direct replacements include the through-hole 2N4854 (TO-78-6) or the tape-and-reel JAN2N4854U/TR. Verify pinout compatibility and package dimensions when substituting between surface-mount and through-hole variants.
