APPLICATION NOTES

RESPONSE TIME

In most applications, the transient suppressor device isplaced in parallel with the equipment or component to beprotected. In this situation, there is a time delay associatedwith the capacitance of the device and an overshootcondition associated with the inductance of the device andthe inductance of the connection method. The capacitanceeffect is of minor importance in the parallel protectionscheme because it only produces a time delay in thetransition from the operating voltage to the clamp voltage asshown in Figure 6.The inductive effects in the device are due to actualturn-on time (time required for the device to go from zerocurrent to full current) and lead inductance. This inductiveeffect produces an overshoot in the voltage across theequipment or component being protected as shown inFigure7. Minimizing this overshoot is very important in theapplication, since the main purpose for adding a transientsuppressor is to clamp voltage spikes. The P6KE6.8A serieshas very good response time, typically < 1 ns and negligibleinductance. However, external inductive effects couldproduce unacceptable overshoot. Proper circuit layout,minimum lead lengths and placing the suppressor device asclose as possible to the equipment or components to beprotected will minimize this overshoot.

Some input impedance represented by Zin is essential toprevent overstress of the protection device. This impedanceshould be as high as possible, without restricting the circuitoperation.

DUTY CYCLE DERATING

The data of Figure 1 applies for non-repetitive conditionsand at a lead temperature of 25°C. If the duty cycle increases,the peak power must be reduced as indicated by the curvesof Figure 5. Average power must be derated as the lead orambient temperature rises above 25°C. The average powerderating curve normally given on data sheets may benormalized and used for this purpose.At first glance the derating curves of Figure 5 appear to bein error as the 10 ms pulse has a higher derating factor thanthe 10 ms pulse. However, when the derating factor for agiven pulse of Figure 5 is multiplied by the peak power valueof Figure 1 for the same pulse, the results follow theexpected trend.TYPICAL PROTECTION CIRCUITZinVinLOADVLV

UL RECOGNITION*

The entire series including the bidirectional CA suffix hasUnderwriters Laboratory Recognition for the classificationof protectors (QVGV2) under the UL standard for safety497B and File #E 116110. Many competitors only have oneor two devices recognized or have recognition in anon-protective category. Some competitors have norecognition at all. With the UL497B recognition, our partssuccessfully passed several tests including Strike Voltage

Breakdown test, Endurance Conditioning, Temperature test,Dielectric Voltage-Withstand test, Discharge test andseveral more.

Whereas, some competitors have only passed aflammability test for the package material, we have beenrecognized for much more to be included in their protectorcategory.
