BC337 APM PBFREE

Single Bipolar Transistors Overview

The Central Semiconductor Corp BC337 APM PBFREE is an NPN silicon epitaxial planar transistor designed for switching and audio frequency amplifier applications. It features a collector-emitter voltage rating of 45 V and a maximum DC collector current of 800 mA. The device offers a DC current gain (hFE) range of 100 to 630, with a transition frequency of 100 MHz. Packaged in a TO-92 through-hole case, it operates within a junction temperature range up to 150 °C and supports storage temperatures from -55 °C to +150 °C.

Single Bipolar Transistors Feature Summary

• Epitaxial planar construction for reliable switching and amplification
• High DC current gain suitable for driver stages
• Low collector-emitter saturation voltage
• Complementary pairing capability with BC327/BC328

Single Bipolar Transistors Applications

• Audio amplifier driver stages
• General-purpose low-power output stages
• Switching circuits requiring moderate current handling

Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning grade required for the application, as the BC337 series is often subdivided into groups such as -16, -25, and -40 based on gain ranges. Confirm that the 'APM' suffix denotes the specific manufacturing lot or packaging configuration intended by Central Semiconductor, ensuring compatibility with existing board layouts and thermal management strategies.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with 800 mA continuous current capability is needed. It is appropriate for designs requiring a balance between high current gain and moderate power dissipation in a TO-92 package. Consider the complementary BC327 if push-pull configurations are required. Ensure the operating voltage remains below the 45 V collector-emitter breakdown limit.

Single Bipolar Transistors Part Context

The BC337 is a widely recognized standard NPN transistor originally defined by semiconductor manufacturers like Motorola and Fairchild. Central Semiconductor produces this part as a lead-free, RoHS-compliant alternative. It belongs to a family of small-signal transistors used extensively in consumer electronics and industrial control boards where through-hole mounting is preferred for mechanical stability.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC337-16, BC337-25, and BC337-40, which differ primarily in DC current gain bins. Other compatible replacements from various manufacturers include the 2N5551 or generic BC337 equivalents, provided they meet the 45 V / 800 mA / TO-92 specifications.
