Honolulu, HI Infineon Technologies developed a family of TVS (transient voltage suppressor) diode arrays intended to protect CAN (controller area network) automotive control networks and industrial bus systems from voltage spikes as high as 30 kV. The dual-channel, bi-directional and uni-directional ESD24V diode arrays are available in the industry-standard SOT23 package. The CAN TVS diode arrays suited to use with applications for powertrain, safety and comfort management systems.
An automotive CAN transceiver must be able to survive the high-energy transients produced by environmental events including load dump, inductive load switching, relay-contact chatter and ignition-system noise. The TVS diodes in the ESD24V arrays have a fast turn-on time and limit the overvoltage to a safe value, absorbing the transient energy to prevent damage to the CAN transceiver and reducing the incidence of field failures.
Features of the ESD24V arrays, which have a maximum operating voltage of 24 V, include an ESD contact discharge rating of 30 kV per diode, a peak pulse current of 5 A, peak pulse power of 180 W and a low reverse current of less than 10 nA. Their performance meets the specifications of the IEC61000-4-2, IEC61000-4-4 and IEC61000-4-5 standards, and are qualified according AEC Q101.
