PROBLEM TO BE SOLVED: To provide a magnetically isolated signal transmission device for preventing a circuit from being complicated while reducing its size and weight. SOLUTION: A zener diode 30 is made to be included between a secondary coil of a pulse transformer 2 and a high input insulated gate field effect transistor 42. Consequently, low bit rate pulse signal transfer can be enabled by a simple circuit constitution. COPYRIGHT: (C)2007,JPO&INPIT
