Description

technology, reliability and compact size to a new family

of High Power Solid State Relays. As part of this new

family, the CPC1777 single-pole normally open

(1-Form-A) DC Solid State Relay employs optically

input to output isolation.

The output, constructed with an efficient MOSFET

switch and photovoltaic die, uses Clare’s patented

OptoMOS architecture while the input, a GaAlAs

infrared LED, provides the optically coupled control.

The combination of low on-resistance and high load

current handling capability makes this relay suitable

for a variety of high performance DC switching

applications.

The unique i4-PAC package pioneered by IXYS

enables solid state relays to achieve the highest load

current and power ratings. This package features an

IXYS unique process where the silicon chips are soft

soldered onto the Direct Copper Bond (DCB)

substrate instead of the usual copper leadframe. The

DCB ceramic, the same substrate used in high power

very low thermal resistance (0.35°C/W).
