IR`s Automotive-Qualified IGBT with Solderable Front Metal Delivers Improved Thermal Performance and Higher Reliability

EL SEGUNDO, Calif.--(Business Wire)--
International Rectifier, IR® (NYSE: IRF), a world leader in power management
technology, today introduced the AUIRG7CH80K6B-M 1200V insulated gate bipolar
transistor (IGBT) with Solderable Front Metal (SFM) for high-current,
high-voltage automotive inverter modules used in electric vehicles (EV) and
hybrid electric vehicles (HEV), as well as medium power drives.

The AUIRG7CH80K6B-M utilizes IR`s latest-generation field stop trench technology
to significantly reduce conduction and switching losses. Additionally, the new
device`s solderable front metal (SFM) allows dual-sided cooling to improve
thermal performance, and enables wire bonds to be eliminated to achieve higher
reliability.

"Traditionally, wire bonds are potentially a source of failure in automotive
inverter modules. The AUIRG7CH80K6B-M with its solderable front metal allows the
use of wire bond-less packaging techniques that together with the dual-sided
cooling feature, provides improved thermal performance, higher efficiency and
extends the reliability of inverter modules," said Fabio Necco, product
marketing manager, IR`s Automotive Business Unit.

Other key performance benefits include square reverse bias safe operating area
(RBSOA), up to 175°C maximum operating temperature, high peak turn-off
capability, positive VCE(on) temperature co-efficient and short-circuit rating
of 6 microseconds. The AUIRG7CH80K6B-M is available in die-form only.

The device is qualified according to automotive standards and is part of IR`s
automotive quality initiative targeting zero defects.
