Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device.

Exposure to any absolute maximum rating condition for extended periods may affect device reliability and

lifetime.

The LT8418 is tested under pulsed load conditions such that TJ ≈ TA. The LT8418A is guaranteed to meet

specifications from –40°C to 125°C junction temperature. High junction temperatures degrade operating

lifetimes; operating lifetime is derated for junction temperatures greater than 125°C. Note that the maximum

ambient temperature consistent with these specifications is determined by specific operating conditions in

conjunction with board layout, the rated package thermal impedance, and other environmental factors. The

junction temperature (TJ, in °C) is calculated from the ambient temperature (TA, in °C) and power dissipation

(PD, in Watts) according to the formula: TJ = TA + (PD • JA), where θJA (in °C/W) is the package thermal impedance.

The LT8418 includes overtemperature protection intended to protect the device during momentary overload

conditions. The maximum rated junction temperature is exceeded when this protection is active. Continuous

operation above the specified absolute maximum operating junction temperature may impair device reliability

or permanently damage the device.
