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 7.
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 inFigure 8. Minimizing this overshoot is very important in theapplication, since the main purpose for adding a transientsuppressor is to clamp voltage spikes. These devices haveexcellent response time, typically in the picosecond rangeand negligible inductance. However, external inductiveeffects could produce unacceptable overshoot. Proper
circuit layout, minimum lead lengths and placing thesuppressor device as close as possible to the equipment orcomponents to be protected 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 6. 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 6 appear to bein error as the 10 ms pulse has a higher derating factor thanthe 10 µs pulse. However, when the derating factor for agiven pulse of Figure 6 is multiplied by the peak power valueof Figure 1 for the same pulse, the results follow theexpected trend.

UL RECOGNITION*
The entire series has Underwriters LaboratoryRecognition for the classification of protectors (QVGV2)under the UL standard for safety 497B and File #116110.Many competitors only have one or two devices recognizedor have recognition in a non-protective category. Somecompetitors have no recognition at all. With the UL497Brecognition, our parts successfully passed several testsincluding Strike Voltage Breakdown test, Endurance
Conditioning, Temperature test, Dielectric Voltage-Withstand test, Discharge test and several 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.

CLIPPER BIDIRECTIONAL DEVICES
1.Clipper-bidirectional devices are available in the1.5KEXXA series and are designated with a “CA”suffix; for example, 1.5KE18CA. Contact your nearestON Semiconductor representative.
2.Clipper-bidirectional part numbers are tested in bothdirections to electrical parameters in preceeding table(except for VF which does not apply).
3.The 1N6267A through 1N6303A series are JEDECregistered devices and the registration does not includea “CA” suffix. To order clipper-bidirectional devicesone must add CA to the 1.5KE device title.
