The relationship between the absorption power (peak value) of transient voltage and the pulse width of transient voltage. The manual only provides the absorption power (peak value) at a specific pulse width, while the pulse width in actual circuits can vary unpredictably and needs to be estimated in advance. The wide pulse should be downgraded for use.

As is well known, the voltage regulator diode must be connected in series with a current limiting resistor during use, otherwise it will be burned out. The maximum operating current of a voltage regulator diode (the maximum operating current refers to the maximum current allowed to pass through the voltage regulator tube during operation) is limited by the maximum dissipated power of the voltage regulator tube (the power at which the heat emitted from the tube will damage the tube when the curre

TVS devices can be divided into two types based on polarity: unipolar and bipolar; It can be divided into universal and specialized types according to its purpose; According to packaging and internal structure, it can be divided into axial lead diodes, dual in-line TVS arrays, surface mount and high-power modules, etc. The peak power of axial lead products can reach 400W, 500W, 600W, 1500W, and 5000W.

In engineering technology, the internal structure of surface mount diodes is basically the same as that of ordinary diodes, both consisting of a PN junction. Therefore, the detection method of surface mount diodes is basically the same as that of ordinary diodes. The detection of surface mount diodes is usually measured using the R × 100 Ω or R × 1 k Ω range of a multimeter.

Single junction transistor (UJT), also known as base diode, is a semiconductor device with only one PN junction and two resistive contact electrodes. Its substrate is a strip-shaped high resistance N-type silicon wafer, and two base electrodes b1 and b2 are respectively led out by ohmic contacts at both ends.

The reverse saturation current Icbo between the collector and base, when the emitter is open (Ie=0) and a specified reverse voltage Vcb is applied between the base and collector, is only related to temperature and remains constant at a certain temperature. Therefore, it is called the reverse saturation current between the collector and base.

A bipolar junction transistor is equivalent to two back-to-back diode PN junctions. The forward biased EB junction injects holes from the emitter into the base region, most of which can reach the boundary of the collector junction and reach the collector region under the action of the reverse biased CB junction potential barrier electric field, forming a collector current IC.
