A tamper resistant electronic lock includes an internal tamper protection circuit and monitoring arrangement that thermally couples a transient voltage suppressor and a resettable fuse of the protection circuit to allow thermal feedback or interaction between the components and to substantially prevent overheating due to the application of overvoltage or out of tolerance current condition applied in an attempt to open the lock for unauthorized access purposes. A thermocouple is used to thermally couple the transient voltage suppressor and the resettable fuse, which acts to limit the current to a safe level when the transient voltage suppressor heats up upon application of the overvoltage or out of tolerance current conditions.
