BC337-25 TRE PBFREE

Single Bipolar Transistors Overview

The BC337-25 TRE PBFREE is an NPN silicon epitaxial planar transistor manufactured by Central Semiconductor Corp. It is housed in a TO-92 (TO-226AA) plastic package and designed for switching and audio frequency amplifier applications. The device features a maximum collector current of 800 mA and a collector-emitter voltage rating of 45 V. The -25 suffix indicates a specific DC current gain bin, typically ranging from 160 to 630 at a collector current of 100 mA. It is compliant with RoHS standards and lead-free manufacturing processes.

Single Bipolar Transistors Feature Summary

• Designed for general-purpose switching and audio frequency amplifier applications

• Available in a standard TO-92 through-hole plastic package

Single Bipolar Transistors Applications

• Audio driver stages
• Low-power output stages
• General-purpose signal switching circuits

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation as Central Semiconductor Corp against the specific part marking. Confirm the -25 gain bin specification aligns with design requirements. Ensure the TRE suffix corresponds to the correct tape and reel packaging format if automated assembly is required. Check for RoHS compliance documentation to meet environmental regulations.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed for low-power amplification or switching. The -25 variant provides a guaranteed minimum hFE of 160, suitable for applications requiring consistent gain without excessive base drive current. Compare thermal dissipation capabilities against the circuit's power load to ensure operation within the 625 mW limit.

Single Bipolar Transistors Part Context

This component belongs to the widely used BC337 family of NPN transistors. It serves as the complementary pair to the BC327 series. The device is commonly found in consumer electronics, industrial control systems, and automotive electronics where small-signal amplification and switching are required. It is functionally equivalent to other manufacturers' BC337-25 variants.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC337-25 from ON Semiconductor, Diotec, and Taiwan Semiconductor. Verify pinout compatibility (Collector-Base-Emitter) and package dimensions before substitution.
