‡
For UL 1449 (2nd Edition), the maximum clamping voltage is measured at 500A.
Mechanical and Environmental Tests
Humidity
The part is subjected to 40±2˚C, 90 to 95% R.H. for 1000 hours without load and then stored at room temperature and ambient humidity for
1 to 2 hours. The change of VB, (∆VB), is then measured and must meet the requirement of
∆VB/VB≤±
5%, where VB is the initial value.
Impulse Life
The maximum surge current (8 x 20µs) listed in this catalog is applied 1000 times continuously with an interval of 30 seconds at room
temperature. The change of VB, (∆VB), is then measured and must meet the requirement of
∆VB/VB≤±
10%, where VB is the initial value.
Low Temperature Storage
The part is subjected to –40±2°C without load for 1000 hours and then stored at room temperature and ambient humidity for 1 to 2 hours.
The change of VB, (∆VB), is then measured and must meet the requirement of
∆VB/VB≤±
5%, where VB is the initial value.
High Temperature Load
After the Maximum Allowable Voltage is applied at 85±2°C for 1000 hours, the part is stored at room temperature and ambient humidity for
1 to 2 hours. The change of VB, (∆VB), is then measured and must meet the requirement of
∆VB/VB≤±10%,
where VB is the initial value.
High Temperature Storage
The part is subjected to 125±2°C for 1000 hours in a drying oven without load and then stored at room temperature and ambient humidity for
1 to 2 hours. The change of VB, (∆VB), is then measured and must meet the requirement of
∆VB/VB≤±5%,
where VB is the initial value.
