Product details

Obsolete — last-time-buy window has closed

The 1.5KE12-E3/54: Vishay lists the 1.5KE12-/54 as Obsolete, meaning the manufacturer no longer produces this order code and the last-time-buy period has ended. A functional replacement would require a parametric match on the 1500W peak pulse rating, the 10.8V minimum breakdown voltage, and the DO-201AA axial footprint — but no pin-compatible direct drop-in is documented.

TransZorb clamping performance at the board level

The 9.72V reverse standoff means it stays off the rail at nominal 12V bus voltage; clamping begins at 10.8V minimum breakdown and limits transients to 17.3V maximum at 86.7A peak pulse current. Through-hole DO-201AA (DO-27) axial package: the leads insert into plated through-holes on the PCB.

Frequently asked questions

What package does the 1.5KE12-/54 use?

It comes in a DO-201AA (DO-27) axial-lead through-hole package. The body is cylindrical with axial wire leads for through-hole PCB mounting.
