On the other hand it can also be used as an amplifier or preamplifier to amplify audio and other type of signals in electronics. When using as a switch it can drive loads of upto 100mA and capable of controlling and driving relays, LEDs, small DC motors, high power transistor etc. Like BC237A can provide DC current gain of 120 to 220, BC237B can provide gain of 180 to 460 and BC237C can provide gain of 380 to 800.īC237 can be used in any general purpose applications that falls under its specs. The device comes in three different part numbers and the only difference between part numbers is their last alphabet which defines the DC current gain value of the device. Due to the specs and features this transistor can be used in replacement of many other general purpose TO-92 BJT transistors. 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. The maximum collector current of the transistor is 100mA due to which it can be used to drive and control many loads in circuits that falls under 100mA. Max Storage & Operating temperature Should Be: -55 to +150 CentigradeīC337, BC547, BC546, BC549, BC550, SS9014, C945 (Pin configuration of some these equivalent transistors may different from BC237, therefore it is necessary to check the transistor’s pinout before replacing)īC237 is a TO-92 package NPN BJT transistor designed for general purpose applications and can be used for both switching and amplifications purposes.
Minimum & Maximum DC Current Gain (h FE): 120 – 800.Max Collector Dissipation (Pc): 500 miliWatt.Max Collector-Emitter Voltage (V CE): 45V.
