Product details

What this 1500W Zener TVS does on a board

The 1.5KE27A: Reverse standoff is 23.1 V typical, so it sits across a 24 V rail without conducting in normal operation; breakdown triggers at 25.7 V minimum. The DO-201AA axial package (also known as DO-27) is a through-hole form factor — you solder it into a board or wire it into a terminal block.
