Abstract
Disclosed is a circuit to provide protection from an over voltage signal. The circuit protects against load dumps or positive transients applied to any electronic unit. The circuit isolates the protected circuitry from the transient voltage by two ways. The circuit limits the current flow and clamping the voltage using a small package zener diode. Additionally, the circuit causes a specific voltage drop between the applied transient and the protected circuit.
