Transient suppressor diode main characteristic parameters TVS diode product characteristics
What are the main characteristic parameters of transient suppression diode and TVS diode? This is a lot of TVS diode for beginners are concerned about the problem of! Then follow the steps to solve these problems for these friends!
Main characteristic parameters of transient suppression diode:
Reverse off state voltage (cut-off voltage) VRWM and reverse leakage current IR: reverse off state voltage (cut-off voltage) VRWM indicates that the TVS diode is not on the highest voltage, only a very small reverse leakage current IR.
II breakdown voltage VBR:TVS diode voltage through the provisions of the current test it. It is said TVS diode conduction through the mark voltage (P4SMA, P6SMB, 1.5SMC, P4KE, P6KE, 1.5ke series models in the figure is the breakdown voltage of the nominal value and other series of digital is reverse off state voltage value). The breakdown voltage of the TVS diode is in the error range of + 5% (without "A" for + 10%).
The pulse peak current IPP:TVS diode allows the maximum peak current (8/20 S wave peak current of about 5 times) through the 10/1000 S wave, more than the current value may cause permanent damage. In the same series, the higher the breakdown voltage of the tube allows the smaller the peak current to pass through.
The maximum clamp voltage VC:TVS voltage through the pulse peak current of IPP at both ends of the.
The pulse peak power PM: pulse peak power PM refers to 10 mu s wave pulse peak current IPP and maximum clamp voltage VC of the product, that is, Pm=IPP*VC.
Transient suppressor diode product characteristics:
Advantages of transient suppression diodes:
The response rate is particularly fast (PS Level)
Breakdown voltage has series from 6.8V to 550V
The voltage is more accurate
Transient suppressor diode:
The junction capacitance is relatively large (more than a dozen pF~ a few hundred nF)
Small flow (0.52~544A)
