Mosorb™ series Zener TVS, 1.5KE15AG, 1500W (1.5kW) peak pulse power, 12.8V reverse standoff, 21.2V clamping, 71A peak pulse current, DO-201AD axial, through hole, bulk.","salesMarkdown":"## Obsolete part — sourcing through independent channels Littelfuse has marked the 1.5KE15AG as Obsolete. No official successor or replacement part number is listed. ## Clamping performance and transient protection envelope The 71 A peak pulse current at that waveform defines the surge capacity into a low-impedance line. Reverse standoff voltage is 12.8 V, meaning the part draws negligible leakage below that rail voltage. This gives a 6.9 V window between the rail and the clamp — enough headroom for a 12 V bus with 5% tolerance. ## Package, mounting, and thermal environment DO-201AD axial-lead package, through-hole mount. The junction temperature range is -65°C to +175°C, covering military and industrial thermal extremes. The axial body solders into a plated through-hole; the lead length and PCB copper area under the body set the effective thermal resistance for repetitive pulse trains. Single unidirectional Zener channel. No power line protection (not designed for AC mains clamping; intended for DC rail transient suppression).","metaTitle":"Littelfuse 1.5KE15AG TVS Diode, 1.5kW, 12.8V Standoff","metaDescription":"Littelfuse 1.5KE15AG Mosorb™ Zener TVS. 1500W peak pulse, 12.8V standoff, 21.2V clamp.
