With 29 mOhm maximum RDS(on) and AEC-Q101 qualification, it is designed for high-side load switching and reverse polarity protection in automotive applications. The TrenchFET technology provides low on-resistance with efficient die utilization. 100% Rg and UIS tested for guaranteed reliability in safety-critical applications.","working_principle":"The SQS401EN operates as a P-Channel enhancement-mode MOSFET:\n\n1. TrenchFET Structure: The trench gate architecture provides high channel density, resulting in low RDS(on) in a compact die. Vertical current flow from source (top) through the channel to drain (bottom) maximizes current handling per unit area.\n\n2. P-Channel Operation: Current flows from source to drain when the gate is pulled below the source (VGS < Vth). For a P-Channel MOSFET, the gate must be negative relative to the source to turn ON. This makes P-Channel MOSFETs ideal for high-side switching, where the load is connected between the MOSFET drain and ground.\n\n3. RDS(on) and Switching: The 29 mOhm RDS(on) at VGS=-10V ensures minimal voltage drop and conduction loss. The 21.2 nC total gate charge enables efficient switching at moderate frequencies.\n\n4. UIS (Unclamped Inductive Switching): 100% UIS tested means each device can safely absorb the energy from an unclamped inductive load, critical for automotive relay and solenoid driving applications.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal - connected to power rail for high-side switch<\/td><\/tr>\n<tr><td>2<\/td><td>Gate<\/td><td>Input<\/td><td>Gate terminal - controls MOSFET on\/off state<\/td><\/tr>\n<tr><td>3<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminal - connected to load<\/td><\/tr>\n<tr><td>4<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal (parallels pin 1 for current handling)<\/td><\/tr>\n<\/table>\n<p>Note: PowerPAK 1212-8 pinout.
