Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

## **Absolute Maximum Ratings** Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted. |**Symbol**|**Parameter**||**Value**|**Unit**| |---|---|---|---|---| |PD|Power Dissipation||500|mW| ||Derate above 50°C||4.0|mW°C| |TSTG|Storage Temperature Range||-65 to +200|°C| |TJ|Operating Junction Temperature Range||-65 to +200|°C| ||Lead Temperature (1/16 inch from case for 10 s)||+230|°C| ## **Note:** 1.
