Littelfuse has marked the 1.5KE47AG as Obsolete. ## Key ratings and what they mean for fit Reverse standoff voltage is 40.2 V — the diode starts conducting above this level, so the protected rail must stay below 40.2 V in normal operation. Breakdown voltage (min) is 44.7 V, meaning the avalanche triggers between 44.7 V and the clamp voltage of 64.8 V. The 23.2 A peak pulse current (10/1000 µs) is the surge it can handle once; for repetitive events, derate per the datasheet's pulse derating curve. Operating temperature spans -65°C to 175°C, covering most industrial and automotive under-hood environments.","metaTitle":"1.5KE47AG Littelfuse Mosorb™ TVS, 1500W, 40.2V Standoff","metaDescription":"1.5KE47AG Littelfuse Mosorb™ Zener TVS, 1500W peak pulse, 40.2V standoff, DO-201AD axial.
