1500W axial TVS — 13.6 V standoff, 22.5 V clamp
The 1.5KE16AG: It clamps at 22.5 V maximum with a peak pulse current of 67 A, and its 13.6 V reverse standoff voltage makes it a fit for protecting 12 V nominal DC rails against transients up to that energy level.
Obsolete — sourced through surplus channels
Littelfuse lists the 1.5KE16AG as obsolete. Availability is through independent surplus and broker inventory. Each lot is date-code and condition verified; quantities are confirmed per RFQ. No pin-compatible direct replacement from Littelfuse is documented, so a board-level substitution would require reviewing the clamping voltage and package footprint against an active alternative.
