FEATURES
1. High sensitivity and low on-
resistance
Max. 0.5A load can be controlled with
5 mA input current. The on-resistance is
low at typ. 2.8.
2. Normally closed (1 Form B) contact
This has been realized thanks to the
built-in MOSFET processed by our
proprietary method, DSD (Double-
diffused and Selective Doping) method.
3. 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.
4. Sockets are also available
(PA1a-PS, PA1a-PS-H)
5. Can be installed on the RT-3 relay
terminal (Power PhotoMOS relay type)
