- Application NotePDF 722 KB R07AN0040EJ0100 Rev.1.00 Nov 13, 2024AI-generated Summary: 48V automotive electrical systems enhance power capacity and efficiency by reducing current and cable size, enabling lighter and more compact vehicle designs. Renesas develops the REXFET-1 series MOSFETs with advanced wafer and package technologies, achieving ultra-low ON-resistance and high reliability for middle-voltage applications. The TOLL and TOLG packages optimize thermal performance, EMI behavior, and space, supporting up to 300A current. These MOSFETs meet automotive standards, improve switching efficiency, and reduce heat dissipation, facilitating the demands of electric and hybrid vehicles' powertrains and auxiliary systems.
- Application NoteAI-generated Summary: Parallel connection of power MOSFETs requires careful management of current balance to prevent device damage. During conduction, differences in RDS(on) and wiring resistance cause current imbalance, which can be mitigated by selecting devices from the same lot and symmetrical layout design. During switching, variations in VGS(th) and inductance lead to transient current imbalance, necessitating similar countermeasures. Avalanche operation risks concentrating current on weaker devices. Parasitic oscillations occur more frequently in parallel configurations due to resonant circuits formed by gate and drain inductances and capacitances, which can be suppressed by adding gate resistors.
- Application NoteAI-generated Summary: Absolute maximum ratings define safe operational limits for MOSFETs, including voltage, current, and temperature thresholds to prevent device damage. Electrical characteristics specify parameters like breakdown voltage, threshold voltage, on-resistance, capacitances, and switching times. Allowable channel dissipation decreases as case temperature rises, calculated by a specific formula. The safe operating area (SOA) outlines five limiting conditions: current rating, on-resistance, channel dissipation, secondary breakdown, and voltage rating, ensuring reliable MOSFET operation under various conditions.
- Application NoteAI-generated Summary: The document outlines derating standards for Power MOSFETs and IGBTs, emphasizing temperature, humidity, voltage, current, and power limits to ensure device reliability. It discusses package type selection between hermetic sealed and plastic molded types, highlighting the advantages of surface-mount packages for miniaturization. It also details precautions for physical handling, including proper lead forming, cutting, and mounting techniques to prevent stress and damage during installation.
