HE (High-function Economy) Type
[2-Channel (Form A) Type]
PhotoMOS RELAYS
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 Ω (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 PhotoMOS relay has only 100 pA even with the rated load voltage of 400 V (AQW254).
6. Low thermal electromotive force (Approx. 1 µV)
TYPICAL APPLICATIONS
• High-speed inspection machines
• Data communication equipment
• Telephone equipment
