Design Kit WE-VD Disk Varistor

Characteristics

Fast response time
Low leakage current
Low clamping voltage
Wide range of voltages available
Almost no energy consumption in stand-by mode
After a surge impulse the varistor works immediately in normal mode so there is no slip current
Excellent absorption at surge impulses
Operating temperature:–40 ºC to +85 ºC for types up to 95 VRMS–40 ºC to +125 ºC for types from 115 VRMS
Response time < 25 ns
UL1449 3rd File E332875
14mm HighSurge and all 20mm Types greater or equal to 50Vrms are certified for use in Type 2 SPD applications (a few parts are still in progress)
CSA File 224856
VDE File 40016986 and 40016998 incl. IEC60950-1 Annex Q

Applications

12–48 VDC distribution
110–400 V power supply
Leakage of voltage peaks
Surge protection in accordance with EN 61000-4-5
