AD4C743
1 Form A / 1 Form B
60V / 1Ω
MOSFET Output Solid State Relay
Description
The AD4C743 is composed of two isolated relays; one
normally open and one normally closed. Each relay has a
bi-directional, single-pole, single-throw contact. Completely
independent of its counterpart, each consists of an LED
driver that activates an integrated circuit, which in turn
drives a pair of DMOS transistors. The low on resistance
(500mΩ TYP) and high load current rating (800mA) make
this relay a unique and unparalleled product.
The AD4C743 comes standard in a compact 8 pin DIP
package making it ideal for high-density board applications.
