Note:

Unless otherwise indicated: TA = +25°C; Junction Temperature (TJ) is approximated by soaking the device under

test to an ambient temperature equal to the desired junction temperature. The test time is small enough such that the

rise in Junction temperature over the Ambient temperature is not significant.
