BC337RL1

Single Bipolar Transistors Overview

The BC337RL1 is an NPN silicon epitaxial transistor from the onsemi BC337 series, designed for amplifier and switching applications. It features a collector-emitter voltage (VCEO) of 45 Vdc and a continuous collector current (IC) of 800 mAdc. The device operates within a junction temperature range of -55 to +150 °C and offers a DC current gain (hFE) ranging from 100 to 630 at IC = 100 mA. Packaged in a TO-92 case style 17, this specific RL1 variant is supplied in tape and reel packaging containing 2000 units per reel.

Single Bipolar Transistors Feature Summary

• NPN silicon epitaxial construction optimized for linear amplification and general-purpose switching tasks
• High DC current gain capability with a wide operational bandwidth suitable for audio driver stages
• Robust thermal performance characterized by low thermal resistance values for efficient heat dissipation

Single Bipolar Transistors Applications

• Audio amplifier driver stages
• General-purpose low-power output stages
• Linear and switching circuits requiring moderate current handling

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix RL1 corresponds specifically to the tape and reel packaging format required for automated assembly processes. Confirm the absence of the G suffix if lead-free compliance is not mandated for the specific production line. Ensure the component matches the standard BC337 electrical specifications rather than the voltage-rated variants such as BC337-16 or BC337-40.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 45 V collector-emitter breakdown and 800 mA continuous current capacity is required. The BC337RL1 provides a cost-effective solution for high-volume manufacturing due to its reel packaging. Consider the complementary BC338 PNP transistor for push-pull configurations. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance.

Single Bipolar Transistors Part Context

This part belongs to the BC337 family of NPN silicon transistors manufactured by onsemi. The family includes various voltage ratings such as BC337-16, BC337-25, and BC337-40, which differ primarily in their collector-emitter breakdown voltages. The BC337RL1 represents the standard 45 V rating configuration packaged for surface mount or automated through-hole insertion systems.

Single Bipolar Transistors Replacement Considerations

BC337RL1G serves as the direct lead-free compliant substitute within the same package and specification profile.
