Product details
Overview
SQS423EN-T1_GE3 from Vishay Siliconix is an automotive-grade P-channel enhancement-mode MOSFET in PowerPAK® 1212-8 package, rated for -30 V drain-source voltage, 0.021 Ω RDS(on) at VGS = -10 V, and continuous drain current of -16 A at TC = 25 °C. It serves as a high-efficiency high-side load switch in 12 V automotive power distribution systems.
For engineers reviewing the SQS423EN-T1_GE3 datasheet, SQS423EN-T1_GE3 pinout, SQS423EN-T1_GE3 application, or SQS423EN-T1_GE3 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C maximum junction temperature, ultra-low thermal resistance (RthJC = 2.4 °C/W), and robust avalanche energy rating (EAS = 24 mJ).
Technical Context
This MOSFET uses TrenchFET® technology to achieve low on-resistance and fast switching with total gate charge of 17–26 nC at VGS = -4.5 V. Its gate threshold voltage range (-1.5 V to -2.5 V) ensures reliable turn-on in 3.3 V and 5 V logic-controlled automotive circuits.
The device integrates a body diode with forward voltage of -0.8 V to -1.2 V at -8.8 A and supports synchronous rectification in buck converters. Its PowerPAK 1212-8 package provides exposed-drain thermal path and achieves junction-to-ambient thermal resistance of 81 °C/W on standard FR4 PCBs.

Pinout & Package
PowerPAK® 1212-8 is a leadless surface-mount package with 8 terminals: four drain pads (D), one gate (G), and three source (S) terminals. The exposed bottom-side drain pad provides primary thermal conduction path to PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, S | Source | Common source node for internal die; connects to ground or low-side return path. |
| 4, G | Gate | Control input; requires ≤±20 V drive; gate resistance 1.6–6 Ω affects switching speed and ringing. |
| 2, 3, 6, 7, 8, D | Drain | High-side power input; all four drain pads and bottom thermal pad are electrically connected and must be soldered to same net. |

FAQ
What is the maximum gate-source voltage rating for SQS423EN-T1_GE3?
The absolute maximum gate-source voltage for SQS423EN-T1_GE3 is ±20 V. Exceeding this rating risks permanent gate oxide damage. In practice, gate drive should be limited to -10 V for full enhancement and -4.5 V for logic-level compatibility, both well within safe operating limits. The device's gate leakage remains below ±100 nA at ±20 V, confirming robust gate insulation integrity in SQS423EN-T1_GE3.
Does SQS423EN-T1_GE3 require a gate resistor in series with the driver?
Yes, a gate resistor is recommended for SQS423EN-T1_GE3 to control dV/dt and suppress ringing during switching transitions. The datasheet specifies gate resistance Rg = 1.6–6 Ω, and typical evaluation circuits use 2.2–10 Ω resistors. This limits peak gate current, reduces EMI, and prevents overshoot that could trigger parasitic turn-on. Proper gate resistor selection directly impacts switching losses and electromagnetic compatibility in SQS423EN-T1_GE3 applications.
How does the PowerPAK 1212-8 package improve thermal performance versus SO-8?
The PowerPAK 1212-8 package in SQS423EN-T1_GE3 achieves RthJC = 2.4 °C/W-nearly 10× better than standard SO-8 (≈20 °C/W)-by exposing the drain pad on the bottom surface for direct PCB thermal coupling. Its compact 3.3 mm × 3.3 mm footprint also allows denser layouts while maintaining superior heat dissipation. This enables SQS423EN-T1_GE3 to sustain -16 A continuously where SO-8 equivalents would thermally throttle or require heatsinks.
Is SQS423EN-T1_GE3 suitable for reverse polarity protection?
Yes, SQS423EN-T1_GE3 is commonly used for reverse polarity protection in automotive 12 V systems. Its P-channel configuration allows placement in the high-side rail, blocking reverse current when battery terminals are swapped. With VDS = -30 V and low RDS(on), it introduces minimal voltage drop (<0.3 V at 10 A) and dissipates less than 3 W under fault conditions. Its AEC-Q101 qualification and 175 °C rating make SQS423EN-T1_GE3 ideal for under-hood reverse protection circuits.
What is the avalanche energy rating of SQS423EN-T1_GE3 and how is it validated?
SQS423EN-T1_GE3 is rated for 24 mJ single-pulse avalanche energy (EAS) with L = 0.1 mH. This rating is verified per JEDEC JESD24-11 using unclamped inductive switching (UIS) tests on 100 % of production units. The parameter ensures robustness against inductive kickback from solenoids, motors, and relays-critical in automotive power distribution. EAS remains valid across the full -55 °C to +175 °C operating range, confirming consistent ruggedness in SQS423EN-T1_GE3.
