BC337-16 PBFREE

Single Bipolar Transistors Overview

The BC337-16 PBFREE is a small signal NPN silicon epitaxial planar transistor designed for switching and audio frequency amplifier applications. It features a collector-emitter breakdown voltage of 45V, a maximum continuous collector current of 800mA, and a power dissipation rating of 625mW. The device belongs to the -16 gain subgroup, offering a minimum DC current gain (hFE) of 100 at a collector current of 100mA. Packaged in a lead-free TO-92 case, it supports a maximum junction temperature of 150°C and includes halogen-free construction.

Single Bipolar Transistors Feature Summary

• Epitaxial planar silicon construction optimized for low saturation voltage and high current gain
• Lead-free and halogen-free compliant packaging suitable for environmentally conscious designs
• Subdivided into specific gain groups (-16, -25, -40) to ensure consistent amplification performance

Single Bipolar Transistors Applications

• Audio driver stages and low-power output amplifiers
• General-purpose switching circuits requiring moderate current handling
• Complementary pairing with BC327/BC328 PNP transistors in push-pull configurations

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix explicitly indicates Pb-free status to ensure compliance with environmental regulations. Confirm the gain bin corresponds to the -16 specification when precise hFE thresholds are required by the circuit design. Check manufacturer documentation for any updates regarding moisture sensitivity levels or recommended soldering profiles for the TO-92 package.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN general-purpose transistor is needed for audio or switching tasks. Ensure the application current remains below the 800mA limit and voltage stays within the 45V VCEO rating. Consider thermal management requirements given the 625mW dissipation limit in free air environments.

Single Bipolar Transistors Part Context

This part is a variant of the widely used BC337 series, distinguished by its specific gain grouping and RoHS-compliant manufacturing process. It serves as a direct replacement for older non-compliant versions while maintaining identical electrical characteristics and pinout compatibility across major semiconductor manufacturers.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC337-16 from other manufacturers such as onsemi, Diodes Incorporated, or Fairchild. Verify that alternative sources specify the same -16 gain bin and TO-92 package dimensions to ensure mechanical fit.
