TVS Diodes are used to protect sensitive circuit from high-voltage transients.Their p-n junctions have a larger crosssectional area than those of a normal diode,allowing them to conduct large currents to ground without damage. SETsafe | SETfuse supplies TVS Diodes with peak power ratings from 200 W to 30 kW,and reverse standoff voltages from 5.0 V to 512 V.
Voltage across TVS in a region of low differential resistance that serves to limit the voltage across the device terminals.
Reverse Stand-off Voltage
Maximum voltage that can be applied to the TVS without operation.
NOTE : It is also shown as VWM (maximum working voltage (maximum d.c. voltage)) and known as rated stand-off voltage (Vso).
Reverse Leakage Current
Current measured at VR.
NOTE : Also shown as ID for stand-by current.
Voltage across TVS at a specified current IT in the breakdown region.
Rated Random Recurring Peak Impulse Current
Maximum-rated value of random recurring peak impulse current that may be applied to a device.
Rated Average Power Dissipation
Maximum-rated value of power dissipation resulting from all sources, including transients and standby current, averaged over a short period of time.
Rated Random Recurring Peak Impulse Power Dissipation
Maximum-rated value of the product of rated random recurring peak impulse current (IPPM) multiplies by specified maximum clamping voltage (VC).
Capacitance across the TVS measured at a specified frequency and voltage
Peak Forward Surge Voltage
Peak voltage across an TVS for a specified forward surge current (IFS) and time duration.
NOTE : Also shown as VF.
Forward Surge Current
Pulsed current through TVS in the forward conducting region.
NOTE : Also shown as IF.
Temperature Coefficient of Breakdown Voltage
The change of breakdown voltage divided by the change of temperature.
Peak pulse Current
Peak pulse current value applied across the TVS to determine the clamping voltage VC for a specified wave shape.
Pulsed D.C. Test Current
Test current for measurement of the breakdown voltage VBR. This is defined by the manufacturer and usually
given in milliamperes with a pulse duration of less than 40 ms.
NOTE : Also shown as IBR .
