HEAVY DUTY (LOAD DUMP) TRANSIENT  
VOLTAGE SUPPRESSOR

DESCRIPTION  
APPEARANCE  
This LDTS series is used in automotive and vehicular applications where  
further protection may be required for load-dump and field-decay transients.  
This type of protection is needed when the battery is disconnected while  
the engine and alternator are still operating. This produces prolonged  
severe transients requiring additional transient voltage suppressor design  
considerations beyond those ratings specified for other conventional TVS  
components.  
TO-3  
(TO-204AD)
