BC237B-AP

Single Bipolar Transistors Overview

The BC237B-AP is a small signal NPN silicon transistor manufactured by Micro Commercial Components. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. The device utilizes a TO-92 through-hole package with three pins. Key electrical characteristics include a minimum DC current gain (hFE) of 120 at 2 mA and 5 V, and a transition frequency of 200 MHz. Maximum power dissipation is rated at 350 mW.

Single Bipolar Transistors Feature Summary

• NPN silicon construction for general-purpose amplification
• High DC current gain suitable for low-level signal processing
• Radial leaded plastic encapsulation for standard mounting

Single Bipolar Transistors Applications

• General purpose switching circuits
• Small signal amplification stages
• Driver applications for logic outputs

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation on the component marking to confirm it originates from Micro Commercial Components rather than other producers such as NXP or CDIL. Ensure the ordering suffix matches the specific gain binning requirements for the intended circuit design. Cross-reference datasheet parameters against the specific lot documentation provided by the supplier to ensure compliance with the stated electrical limits.

Single Bipolar Transistors Selection Notes

Select this component when a low-cost NPN transistor with moderate current handling and high gain is required. The TO-92 package is appropriate for prototyping and low-volume production where surface mount space is not constrained. Compare the 45V rating against the peak voltage in the application to ensure adequate safety margins during operation.

Single Bipolar Transistors Part Context

This part belongs to the BC237 series of NPN transistors, which are widely used in consumer electronics and industrial control systems. The 'AP' suffix typically denotes specific packaging or testing standards defined by Micro Commercial Components. The series is known for its reliability in linear and switching applications within the small signal domain.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC237A and BC237C variants, which share the same pinout but differ in current gain specifications. Other compatible replacements may include generic NPN transistors with similar voltage and current ratings, provided the package type and thermal characteristics are compatible.
