The Littelfuse ATMOV Series of low voltage, high surge cur-
rent, radial leaded varistors provides an ideal circuit protec-
tion for load dump, jump start voltage transient conditions
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) compli-
ant series is available in five disc sizes: 5mm, 7mm, 10mm,
14mm and 20mm; it features a wide VDC voltage range from
16V to 50V.
Note: These parts are in compliance with AEC–Q200 (Table 10).
