What is SL100?
What is an SL100 Transistor? The transistor-like SL100 is a medium, general-purpose power NPN transistor. So this transistor is used in a wide range of electronic applications like switching, logic gates design, reproduction of sound, amplification, signal processing & radio transmission.
Is SL100 an NPN transistor?
Sl100 transistor is a general purpose, medium power NPN transistor.
What is BC547?
BC547 is a Bipolar Junction Transistor, abbreviated as BJT. It is an NPN transistor. It has three terminals named as: Emitter.
Is BC547 a PNP?
BC557 -> BC557 is a PNP Transistor that should be considered for use in design circuits requiring general purpose switching and amplification. The device is available in a TO-92 plastic package. Features: Collector-base voltage(open emitter):-50V.
What is the difference between BC547 and BC548?
BC547 and BC548 are basically the same, but BC547 has more breakdown voltage, while BC548 features low noise. They are the most general-purpose NPN silicon transistors, and switching one to the other will not significantly affect the circuit.
What is hFE BJT?
hFE is an abbreviation, and it stands for “Hybrid parameter forward current gain, common emitter”, and is a measure of the DC gain of a junction transistor.
What is B and C in BC107?
Answered 7 years ago. B stands for Silicon and C means low frequency audio transistor. So BC107 is a low power audio frequency transistor that is made of Silicon.
How many pins are there in 8051?
Definition: 8051 is an 8-bit microcontroller that contains 40 pins of dual-in-line packaging. Out of the 40 pins, 32 pins are allotted to I/O ports. However, in 8051 there exist multiple pins which are assigned more than one signal.
How does the 8051 interrupt work?
When this interrupt is activated (i.e. when it is low), 8051 gets interrupted in whatever it is doing and jumps to the vector value of the interrupt (0003H for INT0 and 0013H for INT1) and starts performing Interrupt Service Routine (ISR) from that vector location. 14th and 15th pin are for Timer 0 and Timer 1 external input.
What is pin40 used for in 8051 microcontroller?
Pin40 (VCC): This VCC pin is used for power supply. There are many applications of 8051 microcontroller. So, 8051 microcontroller projects are of great for engineering final year. Therefore, you can refer any one of the below listed projects to understand the 8051 microcontroller’s pins operations practically.
What is the function of the EA pin on the 8051?
It is used to enable/disable external memory interfacing. In 8051, EA is connected to Vcc as it comes with on-chip ROM to store programs. For other family members such as 8031 and 8032 in which there is no on-chip ROM, the EA pin is connected to the GND.
