MR4045 Datasheet, PDF (1/4 Pages) ON Semiconductor – Automotive Transient Voltage Suppressor

MR4045
Automotive Transient
Voltage Suppressor
34 V – 45 V
Designed for Automotive Applications (Alternator) requiring
Reverse Avalanche Capability for use as Transient Voltage
Suppressor. Developed to suppress transients in automotive systems,
this device operates in the forward mode as Standard Rectifier or in
Reverse as Transient Voltage Suppressor for Centralized Protection.
