Is the NXP PBHV9560ZX PNP transistor (in SC-73 / SOT223 package) safe for PCBs to be used in an MRI (magnetic) environment?
The datasheet says it has a copper-iron alloy lead frame. How much (%) iron is too much for a 3T field strength?
We didn't qualify this product for MRI application.
Though, it is possible to estimate the magnetic force using material content data:
The magnetic force arises at the ferromagnetic materials in gradient of magnetic field (e.g. 3T at 0.5m base).
PBHV9560 contains iron in amount of 0.05mg. So, the related magnetic force @ 6T/m would be less than 5E-5 Newtons.
This is negligible force.
I think, this device is safe for MRI.
