Velox Overview:MOSFETs deficere possunt propter varias passiones electricas, scelerisque et mechanicas. Hos modos defectus cognoscentes pendet ad certas systemata electronicarum potentiarum designandas. Hic dux comprehensivus communes machinas defectas et insidias praeventionis explorat.
Commune MOSFET Defectum Modi et Radix Causae
1. Voltage-Related failures
- Porta oxydatum naufragii
- NIVIS naufragii
- Punch-per
- Static missionem damnum
2. Scelerisque Related failures
- Secundarium naufragii
- Scelerisque fugitivus
- sarcina deminutionem
- Vinculum filum levare-off
| Defectum Modus | Causae primariae | Monitum signa | Methodi praeventionis |
|---|---|---|---|
| Porta Oxide Naufragii | Nimia VGS, ESD certe | Pellentesque porta ultrices | Porta tutela voltage, ESD mensurae |
| Scelerisque Runaway | Luxuriae nimia potentia | Resurgens temperatus, celeritate mutandi reducta | Proprium scelerisque consilium, derating |
| NIVIS DEFECTIO | Spicae intentionis, unclamped inductiva mutandi | Exhaurire fons brevi ambitu | Circuitus simiUs, fibulae intentione |
