STMicroelectronics’ IGBTs Boost Performance with Latest High-Speed Technology

IGBT series delivers efficiency and performance gains for medium- and high-speed applications such as uninterruptible power supplies (UPS) and solar inverters.

The STMicroelectronics HB2 650V IGBT series delivers efficiency and performance gains for medium- and high-speed applications such as PFC converters, welders, uninterruptible power supplies (UPS), and solar inverters, leveraging ST’s latest Trench Field Stop (TFS) technology. The series also includes automotive-eligible devices meeting AEC-Q101 Rev. D.

Joining the STPOWER™ portfolio, the new HB2 series has outstanding conduction performance thanks to low V_CEsat of 1.55V. At the same time, dynamic behaviour is enhanced due to reduced gate charge that enables fast switching at low gate current. Outstanding thermal performance helps maximise reliability and power density, while the new products are also positioned as a very competitive choice in the market.

The HB2 series IGBTs can be specified with either a full-rated or half-rated diode, or a protection diode to prevent accidental reverse bias, giving extra freedom to optimise the behaviour for specific application needs.

The first of the new 650V devices, the 40A STGWA40HP65FB2, is available now in the TO-247 long-lead package, priced from $2.95 for orders of 1000 pieces.

Recently, the company reported its financial results for the first quarter. The company reported first-quarter net revenues of $2.08 billion, gross margin of 39.4%, operating margin of 10.2%, and net income of $178 million or $0.20 diluted earnings per share.

Jean-Marc Chery, STMicroelectronics President & CEO, commented, “In the first quarter of 2019, revenues and gross margin performed as anticipated, amid softened market dynamics. We maintained a solid level of profitability, with an operating margin above 10% and net income of $178 million.

Net revenues totalled $2.08 billion, representing a year-over-year decrease of 6.7%. On a year-over-year basis, the Company recorded lower sales of Microcontroller/Memories, Analog and Imaging, partially offset by growth in Power Discrete, Automotive, Digital and MEMS. Year-over-year sales to OEMs and Distribution decreased by 2.4% and 13.9%, respectively. On a sequential basis, net revenues decreased 21.6%, 90 basis points lower than the mid-point of the Company’s guidance. All product group revenues declined on a sequential basis.
