1500 W bidirectional Zener TVS for 12 V automotive rails
The 1.5KE13CHE3/73: Its 10.5 V reverse standoff voltage and 19 V maximum clamping at 78.9 A peak pulse current make it a fit for protecting 12 V nominal automotive power buses from load-dump and inductive transients.
Protection window and thermal envelope
The breakdown voltage range starts at 11.7 V minimum, ensuring the device begins conducting before the protected rail exceeds the downstream component's absolute maximum rating. The 19 V clamping ceiling limits the voltage seen by the load during a surge event.
Obsolete — sourcing through independent channels
Vishay has marked the 1.5KE13CHE3/73 as obsolete.
