1,200V SOT-227 SiC modules support EV and medical designs

Modules introduced by SemiQ support innovative new designs for electric vehicles (EVs), medical power supplies and solar high power applications, said SemiQ.

The SiC designer and developer has expanded its portfolio of QSiC silicon carbide (SiC) modules with the launch of a family of 1,200V MOSFETs that pair with or without 1,200V SiC Schottky diodes. 

They are supplied in a SOT-227 package. The ceramic-based QSiC modules feature high breakdown voltage (above 1,400V), high temperature operation, with a junction temperature of 175 degrees C, and low Rds(on) shift over the full operating temperature range. Additionally, said SemiQ, they provide industry-leading gate oxide stability and gate oxide lifetime, avalanche (UIS) ruggedness and extended short circuit withstand times.

Automotive and industrial power are target applications for the QSiC modules. Used with the company’s existing SOT-227 SiC SBD modules, they are suitable for EV charging, on-board chargers, DC/DC converters, e-compressors, fuel cell converters, medical power supplies, energy storage systems, solar and wind energy systems, data centre power supplies and UPS / PFC circuits.

All of the new QSiC modules are tested at wafer-level gate burn-in to provide high quality gate oxide with stable gate threshold voltage. The burn-in test helps to stabilise the extrinsic failure rate, but there are also gate stress, high-temperature reverse bias (HTRB) drain stress, and high humidity, high voltage, high temperature (H3TRB) tests to ensure requisite industrial grade quality.

There are six 1,200V SOT-227 module variants, available in 20, 40 and 80 mOhm SiC MOSFET versions.

SemiQ provides efficient standard and custom SiC power semiconductors for high voltage applications. Its product portfolio consists of MOSFETs and diodes, in discrete, module, and bare die formats.

The company has worked with customers from various application areas, including solar energy, EV charging, automotive, medical and energy storage. From the initial concept stage through prototyping and production, it can help design, test, and deploy high-density and optimised solutions, and provide engineering support.
