 Aluminum Nitride Isolator
 Compression Bonded Elements
 Metal Baseplate
 Low Thermal Impedance

for Improved Current Capability

Benefits:

 No Additional Insulation
Components Required

 Easy Installation
 No Clamping Components

Required
 Reduce Engineering Time

Applications:

 Bridge Circuits
 AC & DC Motor Drives
 Battery Supplies
 Power Supplies
 Large IGBT Circuit Front Ends
