ASFETs for Repetitive Avalanche
ASFETs for Repetitive Avalanche are designed to meet the needs of a range of automotive and inductive loads:
- Qualified to AEC-Q101
- Guaranteed repetitive avalanche performance, tested up to 1 billion cycles
- Rugged silicon technology combined with thermal performance of LFPAK, ensures die temperature stays below 175 °C
- Simplicity of using a single MOSFET reduces BOM and circuit complexity, delivering system cost and space savings
- Modern trench alternative to older planar technologies
- Offers increased efficiency and faster switching in comparison to freewheeling diode approach
