Transverse current regulator diode and manufacturing method thereof

The invention belongs to the semiconductor power device technical field and relates to a transverse current regulator diode and a manufacturing method thereof. The transverse current regulator diode is characterized in that a negative feedback resistor is led into the source of an ordinary current regulator diode, so that the performance of the current regulator diode can be higher. The resistor led into the ordinary current regulator diode has a certain voltage drop when working, so that a channel will be pinched off more easily, and the current regulator diode can quickly enter a constant current region, and therefore, the breakdown voltage of the transverse current regulator diode can be effectively improved, and the transverse current regulator diode can have low pinch-off voltage, and the constant current of the transverse current regulator diode can be effectively improved, and the effective operating voltage range of the transverse current regulator diode can be effectively extended. The manufacturing method of the invention is especially suitable for transverse current regulator diodes.
