BC337-25 A1G

Single Bipolar Transistors Overview

The BC337-25A1G is an NPN silicon epitaxial planar transistor manufactured by Taiwan Semiconductor Corporation. It belongs to the BC337 series, designed for general-purpose switching and audio frequency amplifier applications. The device features a maximum collector current of 800 mA and a collector-emitter voltage rating of 45 V. Power dissipation is rated at 625 mW in a TO-92 package. The '25' suffix indicates a specific DC current gain (hFE) binning range, typically 160 to 400. The 'A1G' suffix denotes lead-free construction, RoHS compliance, and halogen-free green compound packaging.

Single Bipolar Transistors Procurement Notes

Verify that the ordering part number explicitly includes the A1G suffix to ensure receipt of the lead-free and RoHS-compliant variant. Confirm the hFE binning corresponds to the -25 specification group required for the circuit design. Check manufacturer documentation for specific moisture sensitivity level classifications and storage conditions prior to assembly.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate current handling and defined gain characteristics is required. The TO-92 through-hole package facilitates easy prototyping and manual assembly. Ensure the application voltage does not exceed the 45 V collector-emitter limit and power dissipation remains within thermal constraints for the plastic case.

Single Bipolar Transistors Part Context

This component is part of the widely used BC337 family of NPN general-purpose transistors. The BC337 series is subdivided into groups based on DC current gain ranges. The BC337-25 variant specifically targets applications requiring a medium gain range, distinguishing it from lower or higher gain counterparts within the same electrical family.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC337-25 from other manufacturers such as NXP, STMicroelectronics, or Micro Commercial Components. Verify pinout compatibility and ensure the replacement part meets the same 45 V and 800 mA ratings.
