If the total is too high then you need a better heat sink. For good reliability you typically want to operate 25-50C below this maximum. Make this circuit by using the following steps then test the circuit by using the LED strips or multimeter. This total can not exceed the maximum for the device as shown on the data sheet (in the case of the referenced transistor it is 200C). Therefore, we are using transistor 2N3055 which is the silicon NPN power transistor intended for general purpose applications and a 5K variable resistor for adjusting the resistance value.
#HOW TO TEST 2N3055 TRANSISTOR HOW TO#
You then add the maximum ambient temperature to that to get the maximum temperate the chip will reach. How to make 100W amplifier circuit using two transistors 2N3055Thank You for watching my video please kindly assist me to like share and subscribe our chann. This is my first experience with transistors. It will be awhile before I will have all of the components to build the target project so I would like to know how to test the 2N3055 transistors. You multiply that sum by the power being dissipated by the chip to determine the chips temperature rise above ambient. I purchased some 2N3055 transistors through eBay today and they were manufactured in India by Continental Device India Limited. To determine the temperature rise of the chip you add all the thermal resistances together. In this post we comprehensively discuss the pinout function, electrical specification, and application designs for the power transistor 2N3055. The 2N3055 is a power bipolar transistor designed to handle high power loads in the range of 100 V, and 15 amps. Most popular NPN power transistor in the world with many applications. 2N3055 Datasheet, Pinout, Application Circuits. If you look at heat sink data it will also have a thermal resistance to air in degrees C/W. Main product image for 2N3055 Transistor 2N3055. Request a Quote Test Houses 2N3055 Specifications Military/High-Rel. This means that each watt the transistor is dissipating will raise the semiconductor chip 1.5 degrees C above the case temperature. SKs+TRANSISTOR+2n3055 datasheet, cross reference, circuit and application notes in. It states that the junction to case thermal resistance is a maximum of 1.5 C/W.

With semiconductors there are several parts to the thermal resistance:Ģ) case to air if mounted in air (this can be many 10's of degrees C/W depending upon the case type)ģ) case to heat sink if mounted on a heat sink (typically a few tenths of a C/W if thermal grease is used)ģ) heat sink to air (varies significantly depending upon the size and type of heat sink) TB 4417 TNY266GN 5243 SMDA05.Thermal resistance is the resistance to the flow of heat in a system which causes a gradient in temperate, must as electrical resistance causes a gradient in voltage when current is flowing.
