AD4C333
1 Form A/1 Form B
Solid State Relay
The AD4C333 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. These transistors are protected with free-wheeling diodes that can handle up to 1.5A of inrush
current, making the relay ideal for switching lamps and highly inductive loads.
