The reverse standoff voltage is 111 V, meaning the diode stays transparent on a 100 V or 110 V rail and only starts conducting when the transient exceeds the minimum breakdown voltage of 117.45 V. ## Package and board-fit: DO-201AA axial leaded Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE130-B is a through-hole part — the leads insert into plated through-holes on the PCB and are wave-soldered or hand-soldered. The wide junction temperature window means the diode can be placed near hot components (power FETs, magnetics) without derating the surge capability at elevated ambient. ## Lifecycle reality: obsolete, sourced through independent channels Littelfuse has marked the 1.5KE130-B as obsolete. For sustainment programs — medical, defense, or industrial control systems that already have this diode in the BOM — the part is available through independent surplus and broker channels. Because the 1.5KE series shares a common DO-201 footprint and pinout across voltage ratings, a functional replacement at a different voltage (e.g., 1.5KE120A or 1.5KE150A) may fit the same PCB land pattern, but the clamping voltage and standoff must be re-verified against the protected rail.","metaTitle":"1.5KE130-B Littelfuse TVS Diode, 1500W, 111V Standoff","metaDescription":"Littelfuse 1.5KE130-B Zener TVS diode, 1500W peak pulse power, 111V reverse standoff, DO-201 package.
