The 89.25 V max clamping voltage at 17.9 A (10/1000 µs) tells you the highest voltage the protected rail will see during a surge event at that current. For a 48 V bus or a 53 V nominal rail, this clamp leaves about 36 V of headroom above the standoff — enough margin for most downstream regulators rated at 100 V or higher. The single bidirectional channel means one device clamps both polarities — useful on AC signal lines or floating DC rails where the polarity isn't fixed. No power line protection feature, so this is a signal or low-power rail protector, not a mains-side suppressor. ## DO-201 axial package — hand-solderable and board-friendly Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE62C-B is a through-hole part you can hand-solder into a prototype or a rework station without hot air. ## Sourcing an obsolete TVS — what to expect With a lifecycle status of Obsolete, the 1.5KE62C-B is no longer manufactured by Littelfuse. For a BOM line that calls out this exact part number, the replacement path is either a last-time-buy from surplus stock or a parametric substitute with the same 1.5KE footprint, 53 V standoff, and bidirectional polarity. The 1.5KE series includes many active bidirectional variants at nearby voltages — a cross-reference search against the 53 V standoff and DO-201 package will surface alternatives that drop in without a board spin.","metaTitle":"Littelfuse 1.5KE62C-B TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE62C-B bidirectional Zener TVS diode, 1500W peak pulse power, 53V standoff, DO-201 axial.
