Hello,

If one attempts to view a larger image of this transistor's datasheet by clicking on the small image at the bottom of the transistor model page, an 'HTTP 500 -' error message appears,

'The server encountered an internal error () that prevented it from fulfilling this request.'

If one clicks on 'More ...' below the image a new page is displayed with seven selectable images,  the same error occurs when one attempts to view a larger image.

Would someone please investigate and correct this error. Thank you

Regards ..... Howard

will be fixed soon 

This problem has already been discussed in a German thread. Hopefully, the bug will be fixed within a week. So we have to be patient.

Regards,

Dietmar
