Question

What kind of applications can Power MOS FET Relays be used for?

Answer



1.Applications where it is not known whether the load connected to the relay is DC or AC.

Example: Warning output for a robot controller

2.Applications with high-frequency switching of loads, such as for solenoid valves with internally, fully rectified waves, where another type of relay (e.g., G2R General-purpose Relays) would need to be replaced frequently.

Power MOS FET Relays have a longer lifetime than other Relays and so the replacement frequency is lower. The terminals of G3RZ Power MOS FET Relays are compatible with those of the G2R-1A-S and so these models can be easily exchanged.

Note:Be sure to confirm the input voltage, polarity, and output capacity.

3.Applications with high-voltage DC loads.

To switch a 100-VDC, 1-A load with M2XP General-purpose Relays or equivalent is required. With G3RZ Power MOS FET Relays, however, switching is possible with this size of relay.

4.Applications where otherwise a Solid-state Relays would be used with a bleeder resistance.

The leakage current for Power MOS FET Relays is very small (10 μA max.) and so a bleeder resistance is not required.
