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...)
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
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.
Apr 24, 2022 · ⑤ Pulse peak power Pm. Pulse peak power Pm refers to the product of the pulse peak current IPP of the 10/1000μs wave and the maximum clamping voltage VC, that is, Pm=IPP*VC. TVS Diode Conduction Characteristics.
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 allowable forward surge current of TVS can reach 50~200A under the condition of TA=250C and T=10ms. Bidirectional TVS diodes can absorb instantaneous large pulse power in both positive and negative directions, and clamp the voltage to a predetermined level.
