High-voltage 1210-size varistor

28 April 2010 Circuit & System Protection

AVX has expanded its multilayer TransGuard range to include an 85 V d.c. rating in a 1210 case size. Designated the VC121085S151 series, the single-chip solution provides bi-directional transient voltage protection in the on-state and excellent EMI/RFI attenuation in the off-state.

Equipped with sub-nanosecond turn-on time, the varistor has the ability to withstand multiple strikes and provides high energy and current handling capability while protecting sensitive circuits from over-voltage conditions caused by ESD, lightning, NEMP and inductive switching. In addition, the devices have a peak current rating of 250 A.

The VC121085S150 series is suited to DC-to-DC converters on hybrid electric vehicles; aftermarket automotive accessories, such as GPS and audio equipment; renewable energy modules using a 48 V bus, like windpowered chargers, solar panels and inverters; as well as commercial and military vehicles.
