Schottky diode avalanche performance in automotive applications

Introduction
Electronic modules connected to automotive power rails may be affected by polarity
inversion due to poor battery handling and load-dump surges when the battery is
disconnected while the alternator is still charging. To protect against these phenomena,
module manufacturers add reverse-battery protection, usually using diodes.
Schottky diodes are preferred over bipolar ones because of their higher performance in
direct conduction. Schottky diodes feature a low forward
