Other Parts Discussed in Thread: PTN78020W

In datasheet P.25, there is the module size information.

Could you give me more detail?

I want to know the following informations,

-each size tolerance.

-size of attached file "2" and "3" point. (between board and module, width of spacer)

-Tallest component height of module back side. 

-is the module lateral side isolated? or does it conduct to any point?

And please let me know the recommended mount condition.

    Data is attached on PTN78020WAH/AD through hole power module.

    The minimum clearance  between bottom side component and mounting to customer (host) PCB assembly is 0.010 (0,25mm) minimum .There are no components to be r located or soldered under the module in the final host board assembly.

    The control components are located on the bottom side of the power module. The components are not electrically  isolated  from any potentially  under  side host board components. Any components located on the host board under the module can potentially short out the power module.

    The recommended PTN78020WAH mount  is the   through - hole by either wave solder process or hand solder process, not  to exceed 260°C for more than  10 seconds.

    Tom-san,

    I want to know module size tolerance.

    In datasheet, there is only typ size data.

    Is the tolerance +/-5% at all point?

    PTN78020W mechanical packages have all tolerances  listed  in notes A-J  on the respective page bottom. The otehr requestred criteria marked as RED request are only typical dimensions and cannot be toleranced .
