ZHCSKN8A december 2019 – april 2023 LM5163H-Q1
PRODUCTION DATA
The LM5163H-Q1 is capable of ultra-high junction temperature operation up to 165°C. High ambient temperature applications with power dissipation on integrated chips often result in junction temperatures exceeding the typical AEC-Q100 Grade 1 specification. The LM5163H-Q1 is designed to sustain these high temperatures while maintaining performance and reliability. This is accomplished by ensured electrical specifications up to 165°C. In addition, extra tests performed on this device show it exceeds AEC-Q100 Grade 1 requirements. For example, the LM5163H-Q1 passes the temperature profile displayed in Table 8-1. Table 8-1 shows an automotive profile of time and temperature for an LM5163H-Q1 converter application specified with 12?000 POH at an input voltage of 100 V. Power On Hours (POH) for LM5163H-Q1 is a function of voltage, temperature, and time. Usage at higher voltages and temperatures results in a reduction in POH to achieve the same reliability performance.
| JUNCTION TEMPERATURE | HOURS (TOTAL = 12?000 HOURS) |
|---|---|
