4. Low capacitance between output
terminals ensures high response
speed:
The capacitance between output termi-
nals is small, typically 10 pF. This enables
for a fast operation speed of 200
µ
s.
5. High sensitivity and low On resis-
tance:
Maximum 0.16 A of load current can be
controlled with input current of 5 mA
(AQW225N). The 10
Ω
On resistance is
less than our conventional models. With
no metallic contacts, the PhotoMOS relay
has stable switching characteristics.
PhotoMOS
RELAYS
6. Low-level off state leakage current:
The SSR has an off state leakage current
of several milliamperes, whereas the Pho-
toMOS relay has only 30 pA even with the
rated load voltage of 80 V (AQW225N).
7. Controls low-level analog signals:
PhotoMOS relay features extremely low
closed-circuit offset voltages to enable
control of small analog signals without
distortion.
8. Low terminals electromotive force:
