Description

CPC44055ST is a voltage-controlled AC Solid State

Switch utilizing dual power SCR outputs. This device

also includes zero-cross turn-on circuitry and is

Tightly controlled zero-cross circuitry ensures low

noise switching of AC loads by minimizing the

generation of transients. The optically coupled input

and output circuits provide exceptional noise immunity

CPC44055ST is well suited for industrial environments

where electromagnetic interference would disrupt the

operation of communications and control systems.

The unique SuperSIP package pioneered by IXYS

Integrated Circuits Division allows Solid State Relays

to achieve the highest load current currently available

in any similar-sized package. This package features a

unique process in which the silicon chips are soft

soldered onto the Direct Copper Bond (DCB)

substrate instead of the traditional copper leadframe.

The DCB ceramic, the same substrate used in high

but also very low junction-to-case thermal resistance

(0.35°C/W).
