![]() The resistance of photoresistor is unknown (am using a snap circuits kit - part 6SCRP). Simulate this circuit – Schematic created using CircuitLab How do I decipher which values to use in the calculator above? Q2: Assuming this is the only way - for S8050 D331. Q1: is this the only way to go about it? Suppose a middle school kid is doing this for a science project, how does the kid understand which resistor to put where? ![]() I was referring to and i have trouble finding the values and calculating them. I need to explain to myself why the circuit does not work if the photoresistor or the load or the extra base resistor are not in their exact positions. Now on to the next step, to know where and when to put what values of resistors so that the photoresistor and S8050 D331 transistor I have together work as a dark detector. The price for an S8050 transistor is 15rupees for 5piece or 0.20USD dollars.I was trying a basic transistor circuit to understand transistors ( LED on the collector without a base limiting resistor ). ![]() The S8050 is a low voltage and high current transistor device, most of the applications of the S8050 transistor are general purpose. When the circuit closes, the transistor triggers ON and allows the current to the motor only at the condition where the control signal reaches it.Īnd also we can control the OFF time of the transistor and control the motor. The figure shows the model for the S8050 transistor switch, the switching operation of the transistor is a common application.īut the S8050 transistor could handle medium current, so for that reason in this example we you motor to switch. S8050 transistor switch S8050 transistor switch The audio signal reaches the transistors separately, both of them equally contribute to the amplification process.Īnd at output both the transistor output combined and reaches the speaker load. This is a model circuit of the amplifier, the circuit consists of two transistors S8050 NPN transistor and its push-pull pair S8550 PNP transistor. The figure shows the circuit of the class B amplifier using S8050 and its complementary transistor. S8050 transistor amplifier circuit S8050 transistor amplifier circuit The comparison between transistors is based on the electrical characteristics, this will help those who need replacement transistors for S8050. The table below is used to compare each of the transistors, S8050 vs BC547 and S8550 vs 2n2222. The transistor equivalent for the S8050 transistor will be S9013, S9014, 2n5551, 2n5830, mps6602, mpsw01ag.Įvery transistor in this list is an NPN transistor, at the replacement process we need to cross-refer electrical specifications because some of the transistors on the list had higher voltage and current values. If you need the datasheet in pdf please click this link S8050 transistor Equivalent The junction temperature of the S8050 transistor is 150☌. The transition frequency on this S8050 transistor is 100MHZ, it is an important factor in switching applications. The S8050 transistor had the maximum power dissipation of 1w, the power dissipation at the transistor device, determine the maximum allowable power dissipation from the device without any damage. The S8050 transistor had a maximum collector current value of 700mA, the maximum current value determine the peak load allowable to the S8050 transistor. The current gain value of the S8050 transistor will start at 40 to 400hFE, the amplifier and voltage regulator circuits mainly consider the current gain value. ![]() S8050 DescriptionĪn S8050 transistor works as a low voltage, high current transistor device at the applications and so due to this reason the S8050 transistors had more general-purpose applications circuits. The main disadvantage of this TO-92 package-based transistor is that it didn’t handle a higher power value, so at the replacement, we need to check all the parameters. The TO-92 package is made with epoxy and plastic material, the compactness and less expensive is one of the advantages of this package. The S8050 transistor had a TO-92 transistor package, it is a very common package used for many merits. The base terminal triggers the transistor
