BC337 TRE TIN/LEAD

Single Bipolar Transistors Overview

The Central Semiconductor Corp BC337 TRE TIN/LEAD is an NPN silicon epitaxial planar transistor designed for switching and audio frequency amplifier applications. It features a maximum collector-emitter voltage of 45 V, a continuous collector current rating of 800 mA, and a power dissipation capacity of 625 mW. The device utilizes a TO-92 (TO-226AA) through-hole package with tin/lead termination. DC current gain ranges from 100 to 630 depending on the specific binning group.

Single Bipolar Transistors Feature Summary

• NPN silicon epitaxial planar construction optimized for general-purpose switching and low-power amplification tasks
• Complementary pairing capability with PNP variants such as the BC327 series for push-pull output stages
• Robust thermal performance supporting junction temperatures up to 150 °C in standard operating environments

Single Bipolar Transistors Applications

• Audio driver stages and low-power output amplifiers
• General-purpose electronic switching circuits
• Complementary transistor pairs in linear amplifier designs

Single Bipolar Transistors Procurement Notes

Verify that the specific order includes the 'TRE' suffix to confirm the tin/lead plating specification, as lead-free alternatives may exist under different suffixes. Confirm the manufacturer is Central Semiconductor Corp, as this part number is widely produced by multiple vendors including onsemi and Fairchild. Ensure the package type matches the required TO-92 footprint for the target PCB design.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with moderate current handling is required. The 800 mA rating supports higher load currents than typical 100 mA signal transistors. Verify the required hFE binning level against the circuit's gain requirements, as the wide range from 100 to 630 necessitates checking the specific datasheet version for the ordered lot.

Single Bipolar Transistors Part Context

This component belongs to the widely adopted BC337 family of NPN transistors. It serves as a fundamental building block in analog electronics, often paired with its PNP counterpart, the BC327. The device is characterized by its versatility in both linear and switching modes, making it a staple in consumer electronics and industrial control circuits requiring reliable low-to-medium power amplification.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC337-16, BC337-25, and BC337-40, which differ primarily in DC current gain grouping. Other compatible replacements from various manufacturers include the 2N5088 or generic BC337 equivalents, provided the pinout and electrical ratings match the original design constraints.
