Surface Mount Power Device(SMPD) and Mini SMPD Packages
Lighter weight, more power(ultra-low profile, energy efficient, and rugged)
January 2013
SMPD OVERVIEW
IXYS introduces a new packaging technology – the Surface Mount Power Device (SMPD)
package. It is an expansion of the ISOPLUS™ package portfolio, which has been providing
isolated-package solutions to the power electronics industry for more than a decade.
Compared to copper-based lead-frame packages, these devices exhibit better thermal perfor-
mance, lower weight, and better power cycling capability.
The SMPD package can be easily surface-mounted on a Printed Circuit Board (PCB) using a
standard pick-and-place and reflow soldering process. No costly screws, cables, bus-bars or
hand soldered contacts are needed. Weighing only 8g, it is much lighter (typically by 50%)
than comparable conventional power modules, thereby enabling lower weight power
systems for IXYS customers. This is one of the key “Green” initiatives of IXYS Corporation in
developing new products for the Cleantech industry that are lighter in weight. Moreover, due
to its compact and ultra-low profile package, it is possible to use the same heat sink for
multiple devices, saving PCB space. Another added benefit of being smaller and lighter is that
it provides a better protection against vibrations and g-forces, especially if used in portable
appliances, increasing the life expectancy and reliability of these devices. IXYS is virtually the
first power semiconductor company to offer surface-mountable high-voltage Power MOSFETs
and IGBTs.
A ceramic isolation of up to 4.5kV is achieved with the Direct Copper Bond (DCB) substrate
technology – an electrically isolated tab is provided for heat sinking. The DCB provides low
thermal impedance and best-in-class power and temperature cycling capabilities. The
ISOPLUS™ advantage also facilitates having multiple die on the same single substrate – buck,
boost, phase-leg, full-bridge, half-bridge configurations are implementable.
“This unique device is part of our initiative of taking power systems on a diet, literally, with the
aim of reducing the weight of the power semiconductors in a typical power system. Weight
reduction is a key effort in reducing greenhouse gas emissions in the production, shipment
and use of power products,” commented Dr. Nathan Zommer, Founder and CEO of IXYS
Corporation, regarding the recently released 1kV/30A Q3 HiperFET™ Power MOSFET in the
SMPD package. “Our lighter products use less material, require less energy to ship, and result
in lower weight products for our customers, a critical desired feature in a lot of applications,
including portable equipment, and for the automotive and transportation industry.”
The new surface-mountable SMPD package is an ideal replacement part for bulky traditional
power modules. IXYS is able to offer various SMPD topologies – the MMIX1F44N100Q3 is a
single die 1000V/30A HiperFET™ Power MOSFET, the IXA68PF650LB a 1200V/68A dual IGBT
with anti-parallel diodes, the DMA90U1800LB a 1800V/99A three phase rectifier diode. Upon
request, IXYS can manufacture other customer-specific configurations.

Heat Sink Mounting Guidelines
The following points should be considered when attaching a heat sink
to the package to ensure a good thermal contact between them. In
general the SMPD is soldered to a PCB as shown in Figure 1. The contact
surfaces of the heat sink must be flat and free of scratches.
• Two holes (30.48mm apart) should be created on the heat sink
surface.
• The recommended depth of thread for an Aluminum (Al) heat sink is
12mm and for a Copper (Cu) one 10mm.
• Unevenness should be less than 50µm over a distance of 100mm and
roughness less than 10µm.
• A thin layer of thermal grease (thickness between 60µm and 80µm)
should be applied to the surface of the heat sink or the base of the
package.
• A recommended mounting screw is M3.5 or 6-32 UNC; tighten the
screws clockwise.

Mini SMPD Overview
To help make even lighter, more efficient, and compact power conversion systems possible, IXYS
offers a smaller version of the SMPD package – the Mini SMPD, which is illustrated in Figure 2
below. Just like in the SMPD, an electrical isolation of 4500V between the semiconductor chip and
base copper is achieved with the Direct Copper Bond (DCB) technology, which is a well-known
technique for high-voltage isolation and provides excellent thermal conductivity and high-current
carrying capability. The structure consists of three layers (Copper, Alumina substrate, and
Copper); the Alumina substrate is a ceramic layer situated between the two copper layers and
supports the necessary voltage isolation. The expansion coefficient of the DCB is close to that of
Silicon, resulting in reliable high-temperature cycling. Compared to standard packages, the Mini
SMPD exhibits better electromagnetic interference (EMI) performance due to its lower parasitic
capacitances and inductances and reduced current loops.
The IXYS Mini SMPD package can be utilized in a wide variety of industrial, consumer, medical,
and green-energy applications, including inverters, battery chargers, switch-mode and resonant
power supplies, temperature and lighting controls, high-frequency plasma generators, motor
drives, E-bikes, and electric and hybrid vehicles.

Mini SMPD ADVANTAGES
• High-voltage electrical isolation (4500V)
• Lower thermal resistance compared to standard packages (TO-247, TO-264, SOT-227B)
• High component density/flexible configurations (H-bridge, half-bridge, boost, buck, phase-leg)
• High current carrying capability
• Low parasitic capacitances and inductances
• Low package weight (5g)
• Better protection against vibrations and g-forces

The figure above illustrates a comparison of the Mini-SMPD with other industry standard packages. The volume of it (3cm

). But the Mini SMPD is able to maintain a high voltage isolation of 4.5kV and weighs just 5g.
