13003 Transistor Explained / Description

13003 is a silicon BJT transistor available in TO-126, TO-92 and other packages (Some packages have slightly different collector current and collector dissipation and voltage specifications). It is manufactured by many electronics component manufacturers and comes in different alphabetic codes before and after the actual transistor number for example MJE13003, APT13003S, ST13003, KSE13003T etc.

13003 is a low cost and easily available transistor. It is built with a special technology that makes this transistor stable and reliable to work on high voltages with very high speed switching capabilities. The device is capable of handling collector-emitter voltage of 400V DC and collector-emitter voltage of 700V DC which makes it ideal to use in wide variety of AC and DC high voltage applications. Although this device is built for high voltage and switching applications but can also be used for general purpose switching and amplification purposes.



Where We Can Use it & How to Use

13003 can be used for many high voltage applications like Inverters, UPS, battery chargers, high voltage power supplies, motor controllers, high voltage relay drivers etc. Additionally it can also be used for general purpose switching and amplification purposes and can also be used in battery operated projects and low voltage hobby and educational electronic projects.

How to Get Long Term Performance in a Circuit

Long life and stable performance of a component in a circuit is also an important factor to think about when you are designing a circuit or if you are using it in an already designed circuit that you are assembling. The max load should not be increased more than 1.5A and 400V DC. Always use a suitable heatsink with the transistor and do not store or operate the transistor in temperature below -65 centigrade and above +150 centigrade.
