Special Issue Information
Dear Colleagues,
Power transistors are core components in modern power electronic systems, widely used in critical fields such as electric vehicles, renewable energy conversion, industrial automation, and consumer electronics. In addition, they can be used in electronic systems operating in harsh environments. With the advancement of technologies toward higher power densities, faster switching speeds, and the widespread adoption of wide-bandgap semiconductors like silicon carbide (SiC) and gallium nitride (GaN), ensuring long-term reliability under increasingly demanding multi-stress operating conditions has become a major challenge.
This Special Issue focuses on degradation and failure mechanisms in power transistors, exploring the complex interplay of electrical, thermal, mechanical, and environmental stresses and their impact on device lifespan. We invite original research and review articles covering topics such as an in-depth understanding of failure physics, accurate lifetime prediction models (particularly those accounting for competing or sequential degradation mechanisms), and novel experimental, simulation, or data-driven approaches for reliability assessment. Contributions addressing condition monitoring, prognostic health management, design-for-reliability strategies, and the influence of emerging materials and device architectures are also highly encouraged.
By bridging fundamental degradation science with practical reliability engineering, this Special Issue aims to advance the development of more robust, predictable, and durable next-generation power electronic systems for future energy and mobility applications.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
