A fail-safe device is provided for a thyristor where the thryistor has a body member with extending tip, ring and ground leads. The fail-safe device includes an electrically conductive spring member having first, second and third contact ends. The spring member is sized to be fitted over the thyristor body with the first contact end opposing the tip lead, the second contact end opposing the ring lead and the third contact end opposing the ground lead. A dielectric spacer is provided disposed to space the first and second contact ends from the tip and ring leads. The spacer means is formed from a material selected to deform under a force of the bias of the spring at an elevated temperature generated in response to the thyristor failing to ground the tip or ring leads during an overvoltage condition.
