Transistor NPN S9013

AED 1.05



SS9013 is a BJT NPN transistor manufactured in the 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 a 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 for general-purpose usage. For full output current i.e. 500mA the transistor needs 50mA at its base. 


  • Collector-base Voltage: 40 V
  • Collector-emitter Voltage: 25 V
  • Collector Current-continuous: 500 mA
  • Collector Dissipation: 625 mW
  • Excellent hFE Linearity
  • Complementary to S9012

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.

How to Safely Long Run in a Circuit:

For safety and long term performance the user should not operate the transistor above 20V, a suitable current limiting resistor for the base of the transistor is essential, always place the pins of the transistor right in the circuit if connected wrong then checks the transistor before placing it again in the circuit, do not connect or operate load more than 500mA with this transistor and always operate and store this transistor in a temperature range above -55 centigrade and below +150 centigrade.
