Sparta Prague, where Srnicek had been goalkeeper coach since 2011, said the former Premier League player died at a university clinic in the eastern city of Ostrava.
Srnicek made 150 appearances for the Magpies from 1991-98 and was part of the Newcastle squad that finished runner-up in the Premier League in 1996. He recently published a book "Pavel Is a Geordie" about his years with Newcastle.
Srnicek played for his country 49 times between 1994 and 2001 and was a backup goalkeeper at the 1996 European Championship, where the Czechs reached the final.
Srnicek also played for English clubs Sheffield Wednesday, Portsmouth and West Ham.
