Hi
Thanks guyas for helping , .i have thought that some one willing to give some info ,, but sorry to say nothing happend , I have ASKED for duplicate for SSP4N90A , becouse it is hard to find here in germany , any way i am self in shame to asking for help ,, where we get nothing .. so i hope thay are lucky if if thay have some information from here ,,

With that kind of attitude i am reluctant to help...but here goes. Mouser has your transistor equivalent, see here [url]http://www.mouser.com/index.cfm?&handler=data.listcategory&D=*SSP4N90A*&terms=SSP4N90A&Ntt=*SSP4N90A*&Dk=1&Ns=SField&N=0&crc=true[/url]
or just search from http://www.mouser.com/

Good luck,
Robert
