BC337B

Single Bipolar Transistors Overview

The BC337B is an NPN silicon epitaxial transistor in a TO-92 package. It features a collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 800 mA. The device has a total power dissipation (PD) of 625 mW at 25°C ambient temperature. DC current gain (hFE) ranges from 160 to 400 under specified test conditions. The transition frequency (fT) is 210 MHz, with a collector-base breakdown voltage (VCBO) of 50 V.

Single Bipolar Transistors Feature Summary

• Suitable for general-purpose switching and amplification applications
• Complementary pairing available with the BC338 PNP transistor
• Designed for low-voltage and low-power circuit operations

Single Bipolar Transistors Applications

• General-purpose amplifier stages
• Low-power output drivers
• Audio pre-amplifier circuits

Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning range required for the application, as the BC337B designation typically corresponds to a specific gain band within the broader BC337 family. Confirm that the TO-92 through-hole package aligns with the target PCB layout. Ensure thermal management strategies account for the 625 mW power dissipation limit when operating near maximum ratings.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate gain and 45 V rating is needed. Compare against other BC337 variants if tighter gain tolerances or different packaging options are required. Consider the complementary BC338 for push-pull configurations. Verify that the 800 mA current limit meets the load requirements without excessive heat generation.

Single Bipolar Transistors Part Context

The BC337 series consists of NPN silicon transistors widely used in consumer electronics and industrial control. Manufactured by Lumimax Optoelectronic Technology, this part follows industry-standard pinouts and electrical characteristics common to the BC108/BC337 family. It serves as a reliable alternative for legacy designs requiring robust small-signal performance.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC337-16, BC337-25, and BC337-40, which differ primarily in DC current gain ranges. Other compatible parts from various manufacturers share identical electrical specifications and pin configurations.
