BC337-25RL1

Single Bipolar Transistors Overview

The BC337-25RL1G is a single NPN silicon epitaxial planar transistor manufactured by onsemi. It is housed in a TO-92-3 through-hole package designed for general-purpose switching and audio frequency amplifier applications. The device supports a maximum continuous collector current of 800 mA and withstands a collector-emitter voltage of 45 V. Key electrical characteristics include a DC current gain (hFE) range of 250 to 630, a transition frequency of 100 MHz, and a power dissipation rating of 625 mW at 25°C ambient temperature.

Single Bipolar Transistors Feature Summary

• High DC current gain classification for precise biasing in amplifier circuits
• Low collector-emitter saturation voltage for efficient switching performance
• Robust thermal stability with high junction temperature capability

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Driver stages for output circuits
• Audio frequency amplifiers

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'RL1G' against official onsemi documentation to confirm reel packaging and lead-free compliance. Confirm the part status as active or obsolete before design finalization. Ensure the ordering code matches the required hFE binning specifications for the intended circuit application.

Single Bipolar Transistors Selection Notes

Select this component when a moderate current capacity of 800 mA is required alongside a specific high-gain binning range. The TO-92 package suits low-power through-hole designs. Compare the 100 MHz transition frequency against higher-speed alternatives if operating near the upper limits of the audio band.

Single Bipolar Transistors Part Context

This part belongs to the BC337 family of NPN transistors, widely used in consumer electronics and industrial control systems. The '25' designation indicates a specific DC current gain subgroup within the broader series. The 'RL1G' suffix typically denotes tape-and-reel packaging and environmental compliance features defined by the manufacturer.

Single Bipolar Transistors Replacement Considerations

Cross-reference with BC337-25BU or BC337-25G from other manufacturers for pin-compatible replacements. Verify that substitute parts meet the same 800 mA current and 45 V voltage ratings.
