The PNP tube on the IC has two longitudinal and transverse types:The longitudinal PnP tube is also called the substrate tube, due to the structural relationship of the internal carrier along the longitudinal movement. The characteristic of this tube is that the base-area width of the

transistor is divided into two types of NPN and PNP type, except the power supply polarity of the different working principle is roughly the same. For the NPN tube, it is composed of 2 N-type semiconductor sandwiched a P-type semiconductor, the emission zone and the formation of the PN Junction between the base region is called the transmission junction, and the Collector zone and the base region formed by the PN Junction is called the junction, three

Row tube Damage is the most common problem in the maintenance of the display, and repeated bad pipe is a headache, so what is the root cause of the problem? In this article, I will explore and summarize the problem in the maintenance practice. In general, there are several reasons for the damage of the line tube: 1. The quality of the pipe has unforeseen defects, the use of natural damage. 2. The capacity

The following is the structure of the transistor and the various identification methods in the circuit diagram When the multimeter is measured against the transistor (buzzer), we first determine which foot is the B-pole. With a red pen touch any one of the feet, the black pen to contact the other two feet, if you can measure the two groups of similar and less than 1 of the number, indicating that the Red pen contact is the B pole. If the two sets of numbers are not similar, it means that the

P Channel MOS transistor as a switch, the gate source of the threshold is -0.4v, when the voltage difference of the gate source is -0.4v will make DS conduction, if S is 2.8v,g to 1.8V, then Gs=-1v,mos tube conduction, D is 2.8V If S is 2.8v,g to 2.8V,VGSW Then the MoS tube is not conduction, D is 0V, So, if 2.8V is connected to S, the MoS Tong is powering the system, and the system is connected to D, us

MoS Tube Learning in the actual project, we basically use the enhanced MOS tube, divided into N-channel and P-Channel two kinds. We often use nmos because of its low on-resistance and easy to manufacture. As can be seen on the MOS schematic, there is a parasitic diode between the drain electrode and the source. This is called a body diode, which is important in driving inductive loads such as motors. Inc

Beginner Python , try to change the program that was previously written in C on the Raspberry Pi. Python version of the. Four-bit common yin digital tube and Raspberry Pi Circuit connection method is as follows:A ~ p-------------------------------GPIO0 ~ GPIO7D1 ~ d4-----------------------------GPIO11 ~gpio8Here is the photo after the circuit is connected:After connecting the circuit to write the program, the program code is as follows:#!/usr/bin/env

This article mainly elaborates the realization planKey words: Open-falcon, Javaxmail, apache-james to achieve complete alarm function, we need 5 steps: 1. Create Rule 2. Data collection 3. Compare rule data with collected data 4. Generate Alarm Data 5. Push Alarm Data And in the pipeline platform, we have integrated small Michae source monitoring system Open-falcon, corresponding to the above analysis of the steps, we give the program is: 1. The k8s Cloud

Enhanced-N Channel MOS tube (e.g. si2300) switching conditions An enhanced n-Channel MOS Tube's s (source source) and D (drain drain) conduction conditions depend on the VGS, the voltage dropout between the gate and the source. only if vgs > 2.5V, which is vg (G-pole voltage)- vs (S-pole voltage) > 2.5v,d and S-poles conduction. For example: G extremely 3.3V, s extremely 0.1V, vgs = 3.3-0.1 = 3.2V > 2.5V, so D-pole and S-pole conduction, D-Pole

If the measured amplification circuit of several transistors three pin to ground point U1.U2.U3 are the following values, try to determine whether they are silicon tube or germanium tube, is NPN or PnP tube. and determine three electrodes of 1. u1=2.5v. u2=6v. u3=1.8v 2. u1=-6v. U2=-3v. u3=-2.8v I would like to draw up a detailed answer procedure. A: (authoritat

VMOs Field effect tube has the advantages of both the electron tube and the advantages of transistors, the power amplifier made with it sound mellow, sweet, dynamic range, frequency response is good, so in recent years in the audio equipment has been widely used. 　　 High-power field-effect tube power amplifier, electric. The road is more complex, the production a

According to the Black Gold AX301 Manual, the digital tube position selected signal is named sel[5:0], wherein SEL[5] corresponds to the leftmost digital tube, and sel[0] corresponds to the right-most digital tube, as a convention, in the following description we call the digital tube 5 and digital

is the Guest account used or not, is this a problem? By default, many Windows systems automatically turn off the Guest account's enabled state, and many users who value the system security will not hesitate to "hit the Killer" on the guest account and not allow it to start running, in the view of these users, as long as the guest account is opened, Then the Windows system encounter hacker attacks will be inevitable! In fact, as long as we manage the Guest account skillfully, we can enjoy the gue

In this article we use Photoshop to create a rusty metal tube effect.1. Start First create a new document with a canvas size of 450 x 450 pixels with a resolution of 72. Fill the background with a very dark color #111111. 2. Draw a rectangle Create a new layer and get a flat-width selection My selection is actually set to 22px, which adds color #5e5e5e to the selection. 3.

Power supply design, or driving circuit, it is inevitable to use the field effect tube, that is, what people often sayMos. Mos have many types and functions. For power supply or driver use, of course, it is to use its switch function. Regardless of the n-type or p-type MOs, the working principle is essentially the same. Mos are the voltage added to the gate at the input end to control the leakage current at the output end. Mos are voltage controlle
