IEEE Transactions Vol COM21 Oct. '73 pp. 1136-43 report that over 99.8% of all lightning transients in open wire, coaxial, and paired cable (over a three year study period) had amplitudes of less than 1 kV with rise time of 10 microseconds or longer and fall times of 50% of peak crest in 1 millisecond. All IAR SurgeBusters pass that requirement as well as the additional standards:
| IEEE 587 Cat B | 1 kV Crest (10 - 1000 microseconds) |
| 3 kV Crest (8 - 20 microseconds) | |
| 6 kV Crest (1.2 - 50 microseconds) | |
| IEEE 472 SWC | 2.5 kV Crest, 1 MHz waveform |
| General Specifications | |
|---|---|
| Response time | <= 1 nanosecond |
| Peak surge current | 5000 amps |
| Clamp voltages available | 6, 12, 25, 50, and 200 V DC to ground, Standard |
| Loop impedance | 24 Ohms, others available |
| Operating Temperature | -40 to +125 C |
| Humidity | 95% RH, non-condensing |
