(1) Thermally limited by junction temperature. Applies when device mounted on TMCS1123xEVM. For more details, see the Safe Operating Area section.
(2) Refer to the Transient Response section for details on transient response of the device.
(3) Lifetime and environmental drift specifications based on three lot AEC-Q100 qualification stress test results. Typical values are population mean +1σ from worst case stress test condition. Maximum values are tested device population mean ±6σ. Devices tested in AEC-Q100 qualification stayed within maximum limits for all stress conditions. See Lifetime and Environmental Stability section for more details.
