FEATURES
1. Compact 8-pin DIP size
The device comes in a compact (W)
6.4
(L) 9.78
(H) 3.9 mm (W)
.252
(L)
.385
(H) .154 inch
, 8-pin DIP size
(through hole terminal type).
2. Applicable for 2 Form A use as well
as two independent 1 Form A use
3. Controls low-level analog signals
PhotoMOS relays feature extremely low
closed-circuit offset voltage to enable
control of low-level analog signals without
distortion.
4. High sensitivity, low ON resistance
Can control a maximum 0.16 A (AQW254)
load current with a 5 mA input current.
Low ON resistance of 16
(AQW254).
Stable operation because there are no
metallic contact parts.
5. Low-level off state leakage current
The SSR has an off state leakage current
of several miliamperes, whereas the Pho-
toMOS relay has only 100 pA even with
the rated load voltage of 400 V
(AQW254).
6. Low thermal electromotive force
(Approx. 1
V)
