Date-code consistency and marking integrity should be verified on receipt — the axial package is straightforward to authenticate by measuring the breakdown voltage (34.2 V min) and comparing the laser etch to known Littelfuse font standards for the Mosorb™ series (cites:,).","metaTitle":"Littelfuse 1.5KE36ARL4G Zener TVS, 1500W, DO-201AD","metaDescription":"Littelfuse 1.5KE36ARL4G Mosorb™ Zener TVS diode, 1500W peak pulse power, 30.8V standoff, DO-201AD axial.
