Abstract
An arrangement for protecting an electronic circuit is suggested which is mounted in a housing and is insulated relative to the housing. At least one connection is provided with which the electronic circuit is connected to a pregiven potential. A voltage-dependent resistor is introduced between the housing and the at least one connection for protecting against ESD-pulses and EMV-irradiation.
