mately 30% at the stated ambient temperature. This current is determined by placing 6. Parts shown in bold are standard catalog parts and are available through sample
the compnent in the specified ambient environment and applying a short duration
pulse current (to eliminate self-heating effect) to the component.
stock and distribution. Parts in lighter font are available but are not necessarily held
in sample stock or distribution and lead times may be longer. Please contact Pulse
for availablity.
3. The rated current is the DC current required to raise the component temperature by
approximately 40�C. Take note that the components’ performanc varies depending
on the system condition. It is suggested that the component be tested at the system
level, to verify the temperature rise of the component during system operation.
4. The part temperature (ambient+temp rise) should not exceed 125�C under worst
case operating conditions. Circuit design, PCB trace size and thickness, airflow and
other cooling provisions all affect the part temperature. Part temperature should be
7. Both the PA and PM part numbers are AEC-Q200 qualified parts. The PM part numbers
have full automotive IATF16949 certification. The PM part number dimensions are
100% tested in production but do not necessarily meet a product capability index
(Cpk)> 1.33 and therefore may not strictly conform to PPAP.
