BC237BRL1

Single Bipolar Transistors Overview

The BC237BRL1 is an NPN silicon amplifier transistor manufactured by onsemi, packaged in a TO-92 (Case 29-11 Style 17) housing. It features a collector-emitter voltage of 45 V and a continuous collector current rating of 100 mA. The device offers a minimum DC current gain (hFE) of 200 at IC = 10 mA and VCE = 5.0 V. Total power dissipation is rated at 350 mW at 25°C ambient temperature with a derating factor of 2.8 mW/°C above this threshold. The unit is supplied in tape and reel packaging containing 2000 units.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1 to confirm the tape and reel quantity of 2000 units. Ensure compatibility with lead-free soldering processes as indicated by the Pb-Free designation. Cross-reference the Case 29-11 dimensions against PCB footprint requirements before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select the BC237B variant when a minimum hFE of 200 is required, distinguishing it from the standard BC237 which specifies a lower gain threshold. Consider the thermal resistance characteristics for heat management in enclosed designs. Verify that the 45 V collector-emitter breakdown voltage meets the circuit's maximum operating voltage requirements.

Single Bipolar Transistors Part Context

This component belongs to the BC237 family of NPN silicon transistors designed for amplifier applications. It serves as a complementary device to PNP counterparts within the same series. The BC237B sub-type specifically targets applications requiring higher current gain compared to the base model, while maintaining identical voltage and current ratings.
