ST's automotive load-dump protection devices protect sensitive semiconductors in electronic modules used for battery charging against load-dump surges when a discharged battery is disconnected from the alternator while the alternator is generating current.
- ISO 7637-2 pulse 5A and 5B standard compliant
- Simple simulation tools to quickly secure the right device selection
Produced using automotive-grade processes and qualified to AEC-Q101, they are identified with the Y extension in the part number for the automotive version of the given protection device.

Introduction to surges – EOS and ESD – definition, standards, effects and root cause
AEC-Q101-qualified LDP01Y series keeps boards safe from load-dump surges
Our datasheet provides four curves to accurately define the surge characteristics and select the appropriate LDP01-xxAY device (‘xx’ being the V BR (typ) at I R = 1 mA).
