The invention discloses an isolated LDMOS device. A deep N-well is divided into an upper part and a lower part and comprises the source region, the drain region and the body region of the device. An isolating ring is formed around the deep N-well. The off-state breakdown voltage of an N pipe and the breakdown voltage of a parasite PN junction between the N-type region of the N pipe or a P pipe and the isolating ring are adjusted by the doping concentration of the upper part. The longitudinal punch-through voltage of a parasite PNP transistor of the N pipe or the P pipe is adjusted by the doping concentration of the lower part. According to the isolated LDMOS device, a process window of device design can be enlarged, integration of the N pipe and the P pipe is facilitated, and application of the N pipe and the P pipe in high-voltage side switches is facilitated; a high-voltage deep N-well is eliminated, and therefore photoetching of a layer is eliminated, the process cost is lowered, and the peripheral area of the device is reduced; the fluctuation influence to the off-state breakdown voltage of the N pipe from the change of the junction position of a high-voltage N-well and the deep N-well can be eliminated, and industrial production control is easy. The invention further discloses a manufacturing method of the isolated LDMOS device.
