3 / 14 page CS51221 http://onsemi.com 3 MAXIMUM RATINGS Rating Value Unit Operating Junction Temperature, TJ Internally Limited − Lead Temperature Soldering: Reflow: (SMD styles only) (Note 1) 230 peak °C Storage Temperature Range, TS −65 to +150 °C ESD (Human Body Model) 2.0 kV Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. 60 second maximum above 183 °C.
