AD4C312 Datasheet, PDF (1/8 Pages) Solid State Optronic – Low Input Control Current (2.5mA TYP)

AD4C312
Dual 1 Form B
400V / 15 Ω
MOSFET Output Solid State Relay
Description
The AD4C312 is composed of two distinct 1 Form B
(normally closed) relays in one compact 8 pin DIP package.
Each relay consists of an AlGaAs LED optically coupled to
a Photo Diode Array, driving a pair of rugged source-to-
source depletion type DMOS transistors. The output MOS
transistors are protected with free-wheeling diodes that can
handle up to 5A of inrush current, making the relay ideal for
switching lamps and highly inductive loads.
The AD4C312 comes standard in a miniature 8 pin DIP
package making it ideal for high-density board applications.
Applications
 Meter Reading Systems
 Multiplexers
 Data Acquisition
 Medical Equipment
 Battery Monitoring
 Home / Safety Security Systems
