What are the specifications of TVS Diode?
TVS diode is an electronic part for protection, which can protect electrical equipment from voltage spikes introduced by wires.
Leakage current: the current that can be turned on when the voltage is less than Zui large reverse turn off voltage.
Maximum reverse turn-off voltage: below this voltage, the diversion current is not obvious
Breakdown voltage: the voltage that will show the conduction current.
Clamp voltage: the voltage at which the conduction current will reach its rated current (hundreds to thousands of AMPS).
Stray capacitance: the diode without conduction has similar characteristics to the capacitor and has destructive effect on high-frequency signal. Generally, TVS Diode with low stray voltage is recommended.
Stray inductance: because the switching of actual overvoltage is very fast, the inductance of packaging is one of the limiting factors of reaction speed.
Absorbable energy: because the transient is very short, all energy becomes the heat of TVS Diode itself. The heat sink will only affect the time required for heat dissipation later, and can not improve the energy absorbed by TVS diode. Therefore, high-energy TVs diodes will also have a large volume. If the volume is not large enough, the overvoltage may damage the TVS diode and cannot protect other circuits.
