surge current, radial leaded varistors provides an ideal circuit
protection for load dump, jump start voltage transient condi-
tions specifically for automotive applications.
The maximum peak surge current rating is rated up to 5kA
(8/20 μs pulse) to protect sensitive infotainment systems
from voltage transients. This AEC-Q200 (Table 10) quali-
fied series is available in five disc sizes: 5mm, 7mm, 10mm,
14mm and 20mm; it features a wide VDC voltage range from
16V to 825V.
