This article describes devices for the suppression of damaging transients in an analog data acquisition system at a common point, making local transient protection unnecessary. Electrical and electronic components connected to an automotive electrical system are constantly being exposed to electrical transients generated from inductive loads, such as motors, solenoids and relays. Presently, transient protection is built into each electronic device. The devices, disclosed herein, eliminate power transients at a common point, making local transient protection unnecessary and allowing a system cost reduction to be realized. When solid-state switching is used to switch loads and control current in a common ground environment, it is desirable to have asymmetrical transient clipping.
