Obsolete — last-time-buy sourcing for existing BOMs
The 1.5KE160CHE3/73 is officially obsolete per Vishay's lifecycle record. No successor order code is listed.
1500 W peak pulse — what the rating means for the protection decision
The 130 V reverse standoff voltage means the device does not conduct at normal 130 V DC or AC peak line levels — it only activates when the transient exceeds the 144 V minimum breakdown threshold. This makes it suitable for 130 V nominal rail protection in automotive 12 V/24 V systems where load-dump or inductive kickback can push the bus well above the steady-state level.
AEC-Q101 TransZorb — automotive-grade transient suppression
The bidirectional single-channel configuration protects against both positive and negative transients on the same line — useful for alternator or solenoid-driven loads where polarity reversal is a risk. The DO-201AA (DO-27) axial-lead package mounts through-hole, suited for point-of-protection on a PCB or in a junction box where a soldered joint provides mechanical retention under vibration.
