The invention relates to a radiation-proof self-recovery over-current/short-circuit protection circuit for a satellite. On the basis of a line structure, the self-recovery over-current/short-circuit protection function is realized. Moreover, the circuit has advantages of reasonable design, small size, and light weight. The radiation-proof self-restoring over-current/short-circuit protection circuit is composed of a power supply module, a triode driver module, a VDMOS tube module including a VDMOS tube Q2, a current detection, amplifier and comparator module, a trigger feedback module having a D trigger U3, and a precision sampling resistor RS1 connected in series to a bus. The power supply module is used for providing power for the current detection, amplifier and comparator module and the trigger feedback module through buses. The input terminal of the triode driver module is connected with an input signal of the control circuit and the output terminal is connected with a gate terminal of the VDMOS tube Q2; and a source end of the VDMOS tube Q2 is connected with the bus by the precision sampling resistor RS1 and a drain end is grounded by a resistor R13. The current detection, amplifier and comparator module consists of a current detection chip U1 for current detection and signal amplification and a comparator U2.
