BC337-40RL1G

Single Bipolar Transistors Overview

The BC337-40RL1G is an NPN silicon epitaxial planar transistor manufactured by onsemi. It is designed for general-purpose switching and amplifier applications. The device features a collector current rating of 800 mA and a collector-emitter voltage of 45 V. It utilizes the TO-92 (CASE 29-11) surface-mount compatible package. The component is lead-free and RoHS compliant, with a maximum power dissipation of 625 mW.

Single Bipolar Transistors Feature Summary

• High DC current gain subdivided into groups based on specific hFE ranges
• Low collector-emitter saturation voltage for efficient switching
• Lead-free construction with halogen-free green compound packaging

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Low-speed electronic switching circuits
• Driver transistor stages in consumer electronics

Single Bipolar Transistors Procurement Notes

Verify the specific suffix RL1G against official onsemi documentation to confirm tape-and-reel packaging and exact binning specifications. Confirm that the -40 designation aligns with required gain thresholds for the target design. Check current lifecycle status as distribution availability may vary across regions.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate current handling and defined gain bins is required. Ensure the application operates within the 45 V collector-emitter voltage limit. Verify thermal management capabilities for the TO-92 package given the 625 mW power dissipation constraint under expected load conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC337 family of NPN transistors, which are widely used in analog and digital circuits. The -40 suffix indicates a specific DC current gain grouping, distinguishing it from other variants like -16 or -25. The RL1G suffix typically denotes reel packaging for automated assembly processes.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC337-40 from other manufacturers such as NXP or Taiwan Semiconductor, provided they meet the same electrical characteristics and pinout configuration.
