Notes:

Note 1.

Device is mounted on a JEDEC single-sided board with 100mm2 of 35μm thick copper, in a one-cubic-foot natural

convection chamber with 1W dissipated power.

Note 2.

ψJB [Psi Junction to Board] provides an estimation of the die junction temperature relative to the PCB [Board] surface

temperature. ψJ-MOSFET [Psi Junction to Drain pin] provides an estimation of the die junction temperature relative to the

Drain pin [internal MOSFET Drain] surface temperature. ψJB is measured at the ground pin (pin 3) without using any

thermal adhesives. See Section 10.14 for more information.

Note 3.

These parameters are typical and they are guaranteed by design.
