SS9013 Transistor Explained / Description:

SS9013 is a BJT NPN transistor manufactured in TO-92 package. It is mostly used for general purpose switching and amplification purposes in commercial devices. Moreover it is also an ideal transistor to use for hobby and educational electronics projects. The transistor is having some very good features in its small TO-92 package due to which it can be used in variety of different electronics applications. The collector-emitter voltage of the transistor is 20V, therefore it can be easily used in electronic applications that require under 20V. The typical saturation voltage of this transistor is 0.16V which is also good as a general purpose usage. For full output current i.e. 500mA the transistor needs 50mA at its base. The gain or hFE is 64 to 202 but this transistor comes in different part numbers which defines its gain like SS9013D gain is 64~91, SS9013E gain is 78~112, SS9013F gain is 96~135, SS901G gain is 112~166 and SS9013H gain is 144~202.


Where We Can Use it & How to Use:

SS9013 can be used in many electronic applications and it is a must to have transistor in your electronics lab. This transistor is basically designed for audio amplification purposes therefore it can be used in circuits where small audio amplification of around 1W is required for example electronic bells, small radios and receiver circuits, amplification of audio signal of any electronic application, electronic buzzer etc. Moreover it can also be used for switching purposes for example the collector current of the transistor is 500mA which is quite good for operating loads like relays, high power LEDs, ICs, electronic applications, another part of a circuit etc. Apart from that it can also be used as an alternative or equivalent transistor for other general purpose transistors in general applications like 2N3904, 2N4401, BC547, BC337, 2N2222 etc.
