No moisture sensitivity level (MSL) rating applies to this hermetic glass-passivated construction — it does not require a pre-bake before reflow, unlike plastic surface-mount TVS diodes. The 175°C maximum junction temperature gives ample margin for high-temperature wave solder profiles. The wide range suits applications from outdoor telecom cabinets to engine-bay electronics where ambient temperatures can exceed 100°C.","metaTitle":"1.5KE12-E3/73 Vishay TransZorb TVS, 1500W, 17.3V Clamp","metaDescription":"Obsolete 1.5KE12-E3/73 from Vishay. 1500W peak pulse, 17.3V clamp, DO-201AA axial.
