Self-disabling detonator and perforation gun system

A detonator is provided. The detonator may include a deflagration-to-detonation transition tube, a cap, and an ignitor. The deflagration-to-detonation transition tube may include a pressure relief mechanism and a low-density explosive material. The cap may be coupled to a first end portion of the transition tube and include a high-density explosive material. The ignitor may be coupled to a second end portion of the transition tube and configured to ignite the low-density explosive material. The pressure relief mechanism may be configured to allow an increase in pressure that leads to a deflagration-to-detonation reaction upon ignition of the low-density explosive material via the ignitor and to prevent the increase in pressure when the detonator is exposed to heat.
