BC337

Single Bipolar Transistors Overview

The onsemi BC337 is a silicon NPN epitaxial planar transistor housed in a TO-92-3 through-hole package. It supports a maximum DC collector current of 800 mA and a collector-emitter voltage (VCEO) of 45 V, with a collector-base voltage (VCBO) of 50 V. The device features a power dissipation rating of 625 mW and a gain-bandwidth product (fT) ranging from 100 MHz to 210 MHz depending on the specific suffix variant. Operating temperatures span from -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• Low-power output stages
• General-purpose switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix code (e.g., RL1G, BU, TA) as it determines packaging type, hFE binning, and availability status. Several variants are marked as End-of-Life or discontinued by onsemi. Confirm RoHS compliance details directly from the manufacturer's datasheet before procurement planning.

Single Bipolar Transistors Selection Notes

Select based on required current gain (hFE) bins and physical mounting needs. Variants like BC33716TA offer kinked leads for PCB spacing, while others use standard straight pins. Ensure the chosen variant meets the specific fT requirements for the intended frequency range and verify thermal management capabilities for the expected power dissipation levels.

Single Bipolar Transistors Part Context

The BC337 belongs to the broader BC337 family of small-signal NPN transistors manufactured by onsemi. This series is widely recognized for its reliability in consumer electronics and industrial control systems. The component serves as a fundamental building block for linear and digital logic interfaces requiring moderate current handling capabilities.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC337_D27Z, BC337BU, BC33740BU, and BC33740TA. These parts share identical electrical ratings and pinouts but may differ in manufacturing origin, hFE grading, or packaging format. Verify mechanical dimensions and lead configurations when swapping between bulk, reel, or ammo pack variants.
