Product details

Obsolete — sourcing from independent stock

The 1.5KE8.2 is marked Obsolete by Littelfuse, meaning the manufacturer no longer produces this part. No pin-compatible direct replacement from Littelfuse is documented.

Clamping performance for 7V rails

The clamping voltage of 12.71V means a 7V rail sees the transient clipped just under 13V, which is within the absolute max of most downstream 12V-rated regulators.

DO-201 axial — board-fit note

Supplied in DO-201AA (DO-27) axial-lead package, through-hole mount. The DO-201 body is larger than the common DO-41; the lead spacing and hole diameter in the PCB layout must match the axial form factor.
