BC337-25,126

Single Bipolar Transistors Overview

The BC337-25,126 is an NPN general-purpose silicon epitaxial planar transistor manufactured by Nexperia (formerly NXP Standard Products). It utilizes the SOT54A plastic single-ended leaded through-hole package. The device supports a maximum collector-emitter voltage of 45 V and a continuous DC collector current of 500 mA. Peak collector current capability reaches 1 A. The -25 selection group specifies a minimum DC current gain (hFE) of 160 at IC = 100 mA and VCE = 1 V. Total power dissipation is rated at 625 mW at 25 °C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix matches the specific packing method required, as the datasheet indicates distinct codes for bulk straight leads versus tape and reel configurations. Confirm that the component source aligns with Nexperia standards, noting the historical transition from NXP Semiconductors. Ensure compliance with RoHS directives and check for any specific marking code variations associated with manufacturing locations.

Single Bipolar Transistors Selection Notes

Select this variant when a minimum DC current gain of 160 is required, distinguishing it from the -16 and -40 groups. Choose the SOT54A package for through-hole mounting requirements where wide pitch leads are necessary. Verify thermal resistance limits against the application's heat dissipation needs to ensure junction temperatures remain within safe operating areas during continuous operation.

Single Bipolar Transistors Part Context

This component belongs to the BC817/BC337 family of NPN general-purpose transistors. The BC337 series specifically designates the through-hole TO-92/SOT54 form factor, contrasting with the surface-mounted BC817 variants. The -25 suffix denotes the specific binning for DC current gain characteristics, ensuring consistent performance across production batches for amplifier and switching designs.

Single Bipolar Transistors Replacement Considerations

Cross-reference with BC337-25 equivalents from other manufacturers such as STMicroelectronics or ON Semiconductor. Verify pinout compatibility, particularly emitter-base-collector orientation in the SOT54 package. Ensure replacement parts meet the same 45 V voltage rating and 500 mA current specifications.
