When a spike hits, the diode clamps at 52.4V max while shunting 30.5A peak pulse current, protecting downstream silicon that would otherwise see the full transient. The reverse standoff voltage is 30.8V, meaning it stays out of the circuit below that level and only starts conducting when the transient exceeds the 32.4V minimum breakdown. ## Obsolete — sourcing reality for a board repair Littelfuse lists the 1.5KE36C-B as obsolete. The scorch mark on the board tells you which part died — this is the one to pull from the BOM and source against a quote. ## Package and board-fit for a through-hole swap Housed in a DO-201AA (DO-27) axial leaded package with the DO-201 supplier device code. The through-hole mounting means it's a straightforward hand-solder replacement on a board that already has the hole pattern. No reflow profile to worry about — just clip the old part, clean the holes, and insert the new one with the banded end oriented correctly for the cathode. The bulk packaging means you're not tied to a reel quantity; single units or small lots are the norm for repair stock.","metaTitle":"Littelfuse 1.5KE36C-B TVS Diode, 1500W, 30.8V Standoff","metaDescription":"Obsolete Littelfuse 1.5KE36C-B bidirectional TVS diode, 1500W peak pulse, 30.8V standoff, DO-201.
