1500W TransZorb in a DO-201AA axial body
The 1.5KE6.8-E3/73: It clamps at 10.8V maximum on a 139A peak pulse current, with a 5.5V reverse standoff voltage and a minimum breakdown of 6.12V. Housed in a DO-201AA (DO-27) axial through-hole package, this part is meant for general-purpose transient suppression on supply rails or signal lines where a single-direction clamp is sufficient.
Obsolete — sourcing through independent channels
Vishay has marked the 1.5KE6.8-/73 as Obsolete. Availability is lot-specific and confirmed at RFQ time — no stock-holding claim from the factory.
What the ratings mean for your board
The 1500W peak pulse rating (10/1000µs) tells you the device can absorb a transient of that energy without failing — useful for clamping inductive kickback or ESD on a 5V rail. The 10.8V clamp voltage at 139A means the protected circuit sees no more than that peak during the event. Through-hole DO-201AA axial package reworks cleanly under a soldering iron — the leads take heat well and the body is marked with the part number and polarity band. Pin 1 is the cathode band; orientation matters for the single-direction clamp.
