Maximum reverse standoff voltage --> the voltage below which no significant conduction occurs. Breakdown voltage --> the voltage at which some specified and significant conduction occurs. I would like to know if I'm trying to use TVS, how to choose the proper diode values if I want to work with Vin = 12V and clamp the spike at 13V?
Oct 15, 2018 · TVS's generally have a minimum breakdown, maximum breakdown and a maximum clamping voltage. These are all current dependent so the specific clamping voltage is dependent on what is being presented to the TVS (source impedance, clamping voltage etc...)
VBR is the voltage value above which the current in TVS increases very fast for a slight increase in voltage. The breakdown voltage V BR is specified at 25 °C and its temperature coefficient is positive.
For optimal IC protection, ensure the TVS diode's clamping voltage is less than the IC's maximum transient voltage threshold. Consider that absolute maximum ratings (AMRs) are based on DC voltage levels, which are
Apr 24, 2022 · • TVS diode: reverse breakdown voltage (VBR), reverse leakage current (IR), maximum reverse working voltage (VRWM), maximum clamping voltage (VC), capacitance value (CJ), maximum Peak Pulse Current (IPP), reverse pulse peak power (PPR), etc.
The reverse working maximum voltage (VRWM) is defined as the voltage that can be applied to a TVS diode with an assurance that the diode will not, over process or temperature, conduct significant current.
Aug 7, 2020 · The main parameters of the TVS tube are reverse breakdown voltage, maximum clamping voltage, instantaneous power, junction capacitance, response time, etc. The response time of TVS can reach the ps level, which is the fastest in voltage-limiting surge protection devices.
