BC337ABU

Single Bipolar Transistors Overview

The BC337ABU is an NPN silicon epitaxial planar transistor manufactured by onsemi, housed in a TO-92-3 through-hole package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 800 mA. The device exhibits a transition frequency of 100 MHz and a maximum DC current gain (hFE) of 630. Operating within a temperature range of -55°C to +150°C, it dissipates up to 625 mW of power with a saturation voltage of 0.7 V.

Single Bipolar Transistors Feature Summary

• Epitaxial NPN silicon construction for reliable switching and amplification
• High DC current gain suitable for driver applications
• Low collector-emitter saturation voltage for efficient operation
• Through-hole TO-92-3 packaging for standard board mounting

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications requiring moderate current handling
• Audio driver stages
• Complementary pairing with PNP transistors like the BC327 series

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'ABU' against the manufacturer's official datasheet to confirm the exact hFE binning and electrical tolerances, as these vary across the BC337 family. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for RoHS compliance status if required by your manufacturing standards. Confirm lead-free marking if applicable to your assembly process requirements.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with 800 mA capability and 45 V breakdown is required. The BC337ABU offers higher current gain compared to standard variants, making it suitable for low-drive applications. Consider thermal management for power dissipation near the 625 mW limit. Verify that the TO-92-3 package fits the mechanical constraints of the target PCB design.

Single Bipolar Transistors Part Context

The BC337 series is a widely used family of NPN bipolar junction transistors designed for general-purpose switching and amplifying tasks. Manufactured by onsemi, these devices are known for their robustness and compatibility with various circuit topologies. The ABU variant specifically denotes a particular gain grouping within this extensive product line, ensuring consistent performance for designers relying on standardized components.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC337-16, BC337-25, and BC337-40, which share identical pinouts and electrical ratings but differ in hFE gain ranges. Other compatible replacements may include generic equivalents like 2N2222 or 2N3904, though these typically have lower current ratings. Always verify pinout compatibility and thermal characteristics before swapping.
