BC337-25,112

Single Bipolar Transistors Overview

The BC337-25,112 is an NPN general-purpose silicon epitaxial planar transistor manufactured by Nexperia (formerly NXP Standard Products). It operates with a collector-emitter voltage of 45 V and a continuous DC collector current of 500 mA. The device features a minimum DC current gain (hFE) range of 160 to 400 at IC = 100 mA and VCE = 1 V. It is housed in the SOT54 (TO-92) plastic single-ended leaded package.

Single Bipolar Transistors Feature Summary

• High current capability for switching applications
• Low voltage operation suitable for general-purpose use

Single Bipolar Transistors Applications

• General-purpose switching
• Amplification circuits

Single Bipolar Transistors Procurement Notes

Verify that the component originates from Nexperia B.V., as the former NXP Standard Product business was rebranded. Confirm the specific ordering suffix matches the required packing method, such as bulk straight leads or delta pinning variants, to ensure compatibility with assembly processes.

Single Bipolar Transistors Selection Notes

Select this variant when a DC current gain between 160 and 400 is required. Ensure the design accommodates the 500 mA continuous collector current limit and the 45 V collector-emitter voltage rating under standard operating conditions.

Single Bipolar Transistors Part Context

This component belongs to the BC817/BC337 family of NPN general-purpose transistors. The family includes surface-mounted options like the BC817 (SOT23) and BC817W (SOT323), alongside through-hole packages. The BC337 specifically utilizes the SOT54 leaded package format.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include BC337-16 and BC337-40, which share identical electrical limits but differ in DC current gain ranges.
