PROBLEM TO BE SOLVED: To provide a semiconductor device trimming circuit structure, which enables Zener breakdown to occur easily between the anode and cathode of a Zener diode with a small set current, without using a large current source such as a power transistor or the like. SOLUTION: In a trimming circuit structure of a semiconductor device, composed of a Zener diode Z connected in parallel with trimming resistors R1 and R2, a capacitor C is connected between the anode and cathode of the Zener diode Z so as to be connected in parallel with the Zener diode Z.
