D13005K NPN Transistor
- D13005K is a bipolar NPN transistor, mainly used for amplification and switching purposes.
- It contains three layers where two n-doped layers surround one p-doped layer.
- This device is made of silicon semiconductor material and comes in a TO-220 package.
- D13005K contains three terminals named base, collector, and emitter. All these terminals are different in terms of doping concentrations.
- The small current at the base side is used to control the large current at the emitter and collector terminals.
- These transistors are called bipolar because both electrons and holes play role in the conductivity inside the transistor.
- Bipolar junction transistors are divided into two main types i.e. NPN and PNP transistors.
- In the case of NPN transistors, electrons are the major charge carriers while holes are major charge carriers in PNP transistors.
- The bipolar junction transistors are the current-controlled devices in contrast to MOSFETs that are voltage-controlled devices that come with terminals named: drain, source, and gate.
- The NPN transistors are preferred over PNP transistors because the mobility of electrons is better than the mobility of holes.
- While in the case of NPN transistors the current flows from the collector to emitter terminals and it flows from emitter to collector terminal in the case of PNP transistors.

D13005K Working PrincipleThe working of this device starts from the base side. When voltage is applied at the base side, it will bias the device and as a result, current starts flowing from collector to emitter terminal. This bipolar device is not symmetrical in nature. And the different doping concentration of all three terminals is the reason these devices are not symmetrical. Which means if you exchange both emitter and collector terminals then these terminals will start operating in reverse active mode and it prevents these terminals to work in forward active mode.
D13005K Power RatingsThe following table shows the D13005K power ratings.
|Absolute Maximum Ratings of D13005K|
|Pin No.||Pin Description||Pin Name|
|7||Operating and storage junction temperature range||-55 to 150C|
- The junction temperature of this device is 150C and the storage temperature ranges from -55 to 150C.
- The collector current is 4A which means this device can support load up to 4A.
- The power dissipation is 75W which is the amount of energy this device releases during the working of this component.
- Know that, don’t apply these ratings more than the required time, else they can affect device reliability.
- The collector-emitter current is 400V and the collector-base voltage is 700V. And the emitter-base voltage is 9V which means this device will get biased when 9V is applied across the base and emitter terminals.
