Availability is lot-dependent; the buyer should expect to quote against their BOM quantity. ## What the 1500W peak pulse rating means for fit The 171V reverse standoff (working voltage) means the diode does not conduct at nominal line voltages up to that level; it starts clamping at a minimum breakdown of 180V and hard-clamps at 287.7V max, passing up to 5.5A of surge current. ## Bidirectional — one device for both polarities A single bidirectional channel protects against positive and negative transients on the same line — useful for AC signal lines or DC rails where reverse polarity surges are possible. No power line protection feature — this is a standalone TVS, not a integrated filter or EMC component. The clamping action is the sole protection mechanism. ## Through-hole axial package — board-fit for legacy rework The DO-201 supplier device package matches the original Littelfuse outline.","metaTitle":"Littelfuse 1.5KE200C-B TVS Diode, 1500W, DO-201, Obsolete","metaDescription":"Littelfuse 1.5KE200C-B bidirectional Zener TVS, 1500W peak pulse, 171V standoff, DO-201 axial.
