Features
• Compact i4-PAC™ Power Package
• Low Thermal Resistance (0.35 °C/W)
• 1.85Arms Load Current with 5°C/W Heat Sink
• Electrically Non-conductive Thermal Pad for Heat
Sink Applications
• Low Drive Power Requirements
• Arc-Free With No Snubbing Circuits
• 2500Vrms Input/Output Isolation
• No EMI/RFI Generation
The CPC1978 employs optically coupled MOSFET
technology to provide 2500Vrms of input to output
isolation. The output is constructed with efficient
MOSFET switches and photovoltaic die that use
Clare’s patented OptoMOS architecture while the
input, a highly efficient 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 switching applications.
• Machine Insertable, Wave Solderable
The unique i4-PAC package pioneered by
IXYS allows solid state relays to achieve the highest
load current and power ratings. This package
features a unique IXYS process where 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 power modules, not only
provides 2500Vrms isolation but also very low thermal
resistance (0.35 °C/W).
Applications
• Industrial Controls
• Motor Control
• Robotics
• Medical Equipment—Patient/Equipment Isolation
• Instrumentation
• Multiplexers
• Data Acquisition
• Electronic Switching
• I/O Subsystems
• Meters (Watt-Hour, Water, Gas)
• Transportation Equipment
• Aerospace/Defense
Approvals
• UL recognized component: File # E69938
• Certified to: UL 508

Thermal Management
Device high current characterization was performed using Kunze heat sink KU 1-159, phase change thermal
interface material KU-ALC 5, and transistor clip KU 4-499/1. This combination provided an approximate
junction-to-ambient thermal resistance of 12.5°C/W.
Heat Sink Calculation
Higher load currents are possible by using lower thermal resistance heat sink combinations.

MANUFACTURING INFORMATION
Soldering
Washing
For proper assembly, the component must be
processed in accordance with the current revision
of IPC/JEDEC standard J-STD-020. Failure to
follow the recommended guidelines may cause
permanent damage to the device resulting in impaired
performance and/or a reduced lifetime expectancy.
Clare does not recommend ultrasonic cleaning or the
use of chlorinated solvents.
