Slim type with high capacity up to 4A DC load type also available

FEATURES
1. Slim SIL4-pin package
   (W) 3.5 ×(D) 21.0 ×(H) 12.5 mm
   (W) .138 ×(D) .827 ×(H) .492 inch
The compact size of the 4-pin SIL package allows high density mounting.
2. Extremely low on-resistance
3. Control low-level signal
Power PhotoMOS feature extremely low closed-circuit offset voltage to enable control of low-level analog signals without distortion.
4. Low-level off state leakage current of max. 10 µA
5. High I/O isolation voltage of 2,500 V
6. Eliminates the need for a counter electromotive protection diode in the drive circuit on the input side
7. Eliminates the need for a power supply to drive the power MOSFET
8. No restriction on mounting direction
9. Low thermoelectromotive force
10. Neither noise nor arc at contact
11. Sockets are also available(PA1a-PS, PA1a-PS-H)
12. Can be installed on the RT-3 relay terminal (Power PhotoMOS type)
