App note: Super Barrier Rectifier (SBR®) improves automotive supply line protection to ISO7637

App note from Diodes Incorporated on their SBR technology which can supports ISO standard supply protection. Link here (PDF)

Electrical disturbances in an automotive environment present reliability and functional risks to the various electronic systems and components that may be exposed. Many modules, for example electronic control units (ECUs), have sensitive microcontrollers at their core and must be shielded to ensure reliable operation. High-voltage transient conduction can be introduced along supply lines by many sources including: ignition systems, inductive components, unexpected conditions such as faults, and connection/disconnection of loads. Depending on the severity these can cause anything from system malfunctions to irreparable component damage.
