FEATURES
1. SO package 4-Pin type in super 
miniature design
The device comes in a super-miniature 
SO package 4-Pin type measuring 
(W)4.3 
× (L)4.4 × (H)2.1 mm 
(W).169 
× 
(L).173 
× (H).083 inch
 —approx. 70% of 
the volume and 70% of the footprint size 
of SO package 6-pin type PhotoMOS 
Relays.
2. Tape and reel
The device comes standard in a tape and 
reel (1,000 pcs./reel) to facilitate 
automatic insertion machines.
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. Low-level off state leakage current
In contrast to the SSR with an off state 
leakage current of several milliamperes, 
the PhotoMOS relay features a very 
small off state leakage current of typ. 
100 pA (AQY214S) even with the rated 
load voltage of 400 V.

Notepad)
• Measuring and Testing equipment
• Factory Automation Equipment
• Security equipment
• High speed inspection machines
