Note: 1. The maximum carry current for output power supply common terminals (B0 to B6) is 3 A.
2. This value fulfills the P reference value for switching at a frequency of 120 times per minute (ambient operating environment and
determination criteria according to JIS C5442).
Power MOS FET Relay Specifications
The following specifications are for the G3DZ when it is mounted on the G70D. They are not the specifications for the G3DZ by itself.

Engineering Data
The following data was obtained from measurements of samples taken from the production line. Relays are mass produced and performance
characteristics will differ from product to product. Therefore, use the following data as reference only.
