Engineering data
ON-state voltage VON Voltage drop between the output terminals when the output MOS FET is in the ON state
Output terminal capaci-

C
OFF/COFF(0V)
Relative ratio based on the capacitance between output terminals when the voltage between the output
terminals is 0 V
Other terms
Current limiting ---
When an overcurrent exceeds a certain value, this function maintains the load current between the minimum
and maximum values of the limit current characteristic. Suppressing the current to a fixed value protects the
relay and the circuit components connected after the relay.
Low C×R ---
Indicator of output characteristics in applications that handle high-frequency signals, fast signals, etc.
C indicates the capacitance between the output terminals in the OFF state, COFF, and R indicates the
resistance between the output terminals, RON, in the ON state. If COFF is large, signal transition even when the
relay is OFF (signal leakage or isolation reduction) and the delay in the signal rise time for signal transition when
the relay is ON (waveform rounding) are affected. If RON is large, signal transition loss (voltage drop and
insertion reduction) is affected. In these applications, a small COFF and RON, i.e., a low C
×
R characteristic,
are important.
