Hybrid semiconductor for AC power circuit protection

ProTek Devices offers a new patent-pending series of hybrid semiconductor components for AC power supply circuit protection in consumer and industrial applications such as home appliances, instrumentation, industrial equipment automation controls, and SMART meters. The new semiconductor technology is an excellent replacement for surface mount MOV devices.

The PHYTVSxxxV3 series is intended to protect industrial and consumer applications where a reliable overvoltage solution with lower clamping voltage is needed. Compared with a MOV, the new series of components provide a more robust product in a small form factor. It does not have a wear-out mechanism common with MOVs. The usage of semiconductor technology significantly increases its operation lifetime.

The new series is compatible with IEC industry standards 61000-4-2 (ESD): level 4 air ±15kV, contact ±8kV; with 61000-4-4 (EFT): 40A; and with 61000-4-5 (surge): L-L class 2, 250Apk, 8/20 microseconds, 500V with Req = 2Ohms. It offers bidirectional operation for 50/60/400Hz AC lines. They are also RoHS and REACH compliant.

The series comprises three devices: The PHYTVS125V3 provides a typical operating voltage of 125V, the PHYTVS250V3 has a typical operating voltage of 250V, and the PHYTVS277V3 has a typical operating voltage of 277V.
