Surface Mount Power Device(SMPD) and Mini SMPD Packages

P R ODU C T BRIEF
Lighter weight, more power(ultra-low profile, energy efficient, and rugged)
SMPD OVERVIEW
IXYS introduces a new packaging technology – the Surface Mount Power Device (SMPD)
package. It is an expansion of the ISOPLUS™ package porolio, which has been providing
isolated-package soluons to the power electronics industry for more than a decade.
Compared to copper-based lead-frame packages, these devices exhibit beer thermal perfor-
mance, lower weight, and beer 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 convenonal power modules, thereby enabling lower weight power
systems for IXYS customers. This is one of the key “Green” iniaves of IXYS Corporaon 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
mulple devices, saving PCB space. Another added benefit of being smaller and lighter is that
it provides a beer protecon against vibraons 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 isolaon 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 capabilies. The
ISOPLUS™ advantage also facilitates having mulple die on the same single substrate – buck,
boost, phase-leg, full-bridge, half-bridge configuraons are implementable.
“This unique device is part of our iniave 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
reducon is a key effort in reducing greenhouse gas emissions in the producon, shipment
and use of power products,” commented Dr. Nathan Zommer, Founder and CEO of IXYS
Corporaon, 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 crical desired feature in a lot of applicaons,
including portable equipment, and for the automove and transportaon industry.”
The new surface-mountable SMPD package is an ideal replacement part for bulky tradional
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 an-parallel diodes, the DMA90U1800LB a 1800V/99A three phase recfier diode. Upon
request, IXYS can manufacture other customer-specific configuraons.
