BC237B APM PBFREE

Single Bipolar Transistors Overview

The BC237B APM PBFREE is an NPN silicon small signal bipolar junction transistor manufactured by Central Semiconductor Corp. It features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 100 mA. The device has a power dissipation capacity of 300 mW and a transition frequency of 150 MHz. It is housed in a TO-92-3 through-hole package with an operating temperature range from -65°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN polarity configuration for general-purpose amplification and switching applications
• Through-hole mounting capability via TO-92-3 package format
• Silicon construction designed for high-frequency operation up to 150 MHz

Single Bipolar Transistors Applications

• General purpose amplifier circuits
• Electronic switching applications
• Small signal processing tasks

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required packaging, as APM denotes Ammo Pack while other suffixes may indicate Bulk or Tape & Reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies. Ensure the component meets the required thermal and electrical specifications for the target design environment before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with moderate voltage ratings and low current handling is required. The TO-92-3 package suits prototyping and low-volume production where through-hole assembly is preferred. Consider the 150 MHz transition frequency for audio or intermediate frequency applications rather than high-speed digital switching.

Single Bipolar Transistors Part Context

This part belongs to the BC237 series of NPN transistors produced by Central Semiconductor Corp. The series offers variants with different packaging options such as TRE (Bulk) and APM (Ammo Pack). These components are commonly used in consumer electronics and industrial control systems requiring reliable small-signal performance.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC237C for higher gain requirements or the BC237D for even higher gain specifications. Other compatible NPN transistors with similar voltage and current ratings should be evaluated for pin compatibility and thermal characteristics before substitution.
