The new parts, called the EP9 series and aimed at both IGBTs and mosfets, are built on a MnZn ferrite core with surface-mount L-pin construction.
Creepage and clearance is 5mm, peak withstanding is 2.5kVac 50Hz, and coupling capacitance is only 2pF.
Operation is over -40 to +150°C and, suiting them to automotive applications, they comply with AEC-Q200 Rev E.
There are two devices (see table), both intended to work around 100 to 400k, one for half-bridge converters and the other for push-pull converters.

Indeed, ‘EP9’ does not occur in the part numbers.
For development, sample kit B82804X1 has six of each type.
