650V high-frequency IGBTs boost performance

New from STMicroelectronics, the HB2 650V IGBT series has been designed to deliver efficiency and performance gains for medium- and high-speed applications.

These applications include 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 HB2 series has an improved conduction performance thanks to a low VCEsat of 1.55V. At the same time, dynamic behaviour is enhanced due to reduced gate charge that enables fast switching at low gate current. An enhanced thermal performance helps maximize reliability and power density.

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 optimize the behaviour for specific application needs.
