The DFM1200FXM18-A000 is a dual 1800 volt, fast
recovery diode (FRD) module. Designed for low power
loss, the module is suitable for a variety of high voltage
applications in motor drives and power conversion.
Fast switching times and low reverse recovery losses
allow high frequency operation making the device suitable
for the latest drive designs employing pwm and high
frequency switching.
These modules incorporate electrically isolated base
plates and low inductance construction enabling circuit
designers to optimise circuit layouts and utilise grounded
heat sinks for safety.

ABSOLUTE MAXIMUM RATINGS - PER ARM
Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. In extreme
conditions, as with all semiconductors, this may include potentially hazardous rupture of the package. Appropriate safety
precautions should always be followed. Exposure to Absolute Maximum Ratings may affect device reliability.

POWER ASSEMBLY CAPABILITY
The Power Assembly group was set up to provide a support service for those customers requiring more than the basic
semiconductor, and has developed a flexible range of heatsink and clamping systems in line with advances in device voltages
and current capability of our semiconductors.
We offer an extensive range of air and liquid cooled assemblies covering the full range of circuit designs in general use today.
The Assembly group offers high quality engineering support dedicated to designing new units to satisfy the growing needs of
our customers.
Using the latest CAD methods our team of design and applications engineers aim to provide the Power Assembly Complete
Solution (PACs).
HEATSINKS
The Power Assembly group has its own proprietary range of extruded aluminium heatsinks which have been designed to
optimise the performance of Dynex semiconductors. Data with respect to air natural, forced air and liquid cooling (with flow
rates) is available on request.
For further information on device clamps, heatsinks and assemblies, please contact your nearest sales representative or
Customer Services.
