BC237

Single Bipolar Transistors Overview

The onsemi BC237 is an NPN epitaxial silicon small-signal transistor housed in a TO-92 package. It features a collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) rating of 100 mA. The device offers a DC current gain (hFE) range of 120 to 800, depending on the classification grade. Key electrical characteristics include a transition frequency (fT) up to 250 MHz and a maximum power dissipation of 500 mW at 25°C ambient temperature.

Single Bipolar Transistors Feature Summary

NPN epitaxial silicon construction for reliable signal processing
High DC current gain suitable for amplification tasks
Low noise performance optimized for sensitive circuits
Robust switching capabilities with defined saturation voltages

Single Bipolar Transistors Applications

General-purpose amplifier stages
Electronic switching circuits
Audio pre-amplifier input stages

Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning code (A, B, or C) required for your design, as gain ranges vary significantly between classifications. Confirm the manufacturer source, as this component was originally produced by Fairchild Semiconductor before acquisition by onsemi. Ensure the TO-92 package variant matches your PCB footprint requirements.

Single Bipolar Transistors Selection Notes

Select the BC237 when a general-purpose NPN transistor with moderate voltage ratings and high gain is needed. Compare against BC238 or BC239 if lower voltage or specific low-noise characteristics are prioritized. Consider the thermal resistance and power dissipation limits when designing heat management solutions for continuous operation.

Single Bipolar Transistors Part Context

This component belongs to the BC23x family, which includes the BC237, BC238, and BC239 variants. These transistors share similar physical packaging and basic operational principles but differ in voltage ratings and noise specifications. The BC237 specifically targets applications requiring a balance of voltage handling and current gain.
