It can be operated with a wide range of supply which is from 3V to 32V DC due to which it can easily be used with low voltage logic devices and microcontrollers.Other than that it can also be used to amplify any kind of low gain signals

On the other hand the maximum collector dissipation of 500mW and max DC current gain of upto 800 makes it ideal to use in audio and other electronic signal amplification purposes.On the other hand it can also be used as an amplifier or preamplifier to amplify audio and other type of signals in electronics.

Like BC237A can provide DC current gain of 120 to 220.push({});Features / Technical SpecificationsPackage Type: TO-92Transistor Type: NPN Max Collector Current(IC): 100mAMax Collector-Emitter Voltage (VCE): 45VMax Collector-Base Voltage (VCB): 50VMax Emitter-Base Voltage (VEBO): 6VMax Collector Dissipation (Pc): 500 miliWattMax Transition Frequency (fT): 150 MHzMinimum Maximum DC Current Gain (hFE): 120 – 800Max Storage Operating temperature Should Be: -55 to +150 Centigrade PNP ComplementaryPNP Complementary of BC237 is BC307Replacement and EquivalentBC337.
