Original title: bidirectional transient suppression diode
Transient voltage suppression diode is abbreviated as TVS tube, in which unidirectional transient suppression diode and bidirectional transient suppression diode are distinguished according to polarity. It is a high-performance protection device. When TVS diode is subjected to high transient energy impact, it can absorb surge current and voltage at microsecond speed, protect electrical equipment, and has the characteristics of small size and fast response time. It is widely used in anti-lightning, anti-overvoltage, anti-static and anti-interference household appliances, instruments and meters, communication equipment, computers, security, satellite navigation and other equipment. What is the difference between unidirectional and bidirectional transient suppression diodes? Parse as follows.
Difference between unidirectional and bidirectional transient suppression diode
The forward characteristic of unidirectional transient suppression diode is the same as that of ordinary zener diode, and the everse breakdown inflection point is approximately "right angle", which is a typical PN junction avalanche device. The curve segment corresponding to Vc value from breakdown point shows that when there is instantaneous overvoltage pulse, the current of the device increases rapidly, while the everse voltage rises to the clamping voltage value and remains at this level.
Bidirectional transient suppression diodes can absorb instantaneous large pulse power in both positive and negative directions and clamp the voltage to a predetermined level. Bidirectional transient suppression diodes are suitable for AC circuits, while unidirectional transient suppression diodes are generally used for DC circuits. The maximum pulse peak current that the device is allowed to pass under the specified pulse condition during everse operation. The product of IPP and the maximum clamping voltage Vc(MAX) is the maximum value of transient pulse power.
