Product details
Overview
SIS782DN-T1-GE3 from Vishay Siliconix is an N-channel 30 V (D-S) TrenchFET® power MOSFET with monolithically integrated SkyFET® Schottky diode in a PowerPAK® 1212-8 package. It delivers RDS(on) of 9.5 mΩ at VGS = 10 V and 12.0 mΩ at VGS = 4.5 V, supports 16 A continuous drain current, and serves as a synchronous rectifier switch or buck converter primary/secondary switch in notebook PC power systems.
For engineers reviewing the SIS782DN-T1-GE3 datasheet, SIS782DN-T1-GE3 pinout, SIS782DN-T1-GE3 application, or SIS782DN-T1-GE3 equivalent, key selection criteria include its integrated Schottky body diode for reduced reverse recovery loss, ultra-low 2.4 °C/W junction-to-case thermal resistance, and validated 100 % Rg and UIS testing for robust switching reliability in high-frequency DC-DC converters.
Technical Context
This device implements a monolithic SkyFET® architecture-integrating a trench-gated N-channel MOSFET and a low-VF Schottky diode on a single die-enabling self-synchronous rectification without external diode placement. Its gate threshold voltage (1.0–2.3 V) and low Qg (9.5 nC typ. at 4.5 V) support efficient 4.5 V gate drive in space-constrained notebook power rails.
The PowerPAK® 1212-8 package features an exposed copper drain pad on the bottom side for direct thermal conduction to the PCB, achieving RthJC = 2.4 °C/W (max 3.0 °C/W) and RthJA = 28 °C/W (typical, 1" × 1" FR4). The 1.07 mm profile and 3.3 mm × 3.3 mm footprint enable high-density layout in thin-profile computing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage; suitable for 5 V–12 V input buck stages and 3.3 V/5 V output rails. |
| RDS(on) @ 10 V | 9.5 mΩ max - Enables ≤150 mW conduction loss at 10 A, critical for thermally constrained notebook memory/system power. |
| RDS(on) @ 4.5 V | 12.0 mΩ max - Ensures stable on-resistance under logic-level gate drive from standard PWM controllers. |
| Qg @ 4.5 V | 9.5 nC typ. - Low gate charge reduces switching loss and eases gate driver sizing in 300–1000 kHz converters. |
| ID (continuous) | 16 A @ TC = 25 °C - Rated for high-current synchronous rectification in compact 1212-footprint layouts. |
| VSD @ 2 A | 0.44–0.55 V - Integrated Schottky diode provides lower forward drop than conventional body diodes, reducing dead-time losses. |
| RthJC | 2.4 °C/W typ. - Direct thermal path from junction to case enables >25 W power dissipation with minimal heatsinking. |
Pinout & Package
PowerPAK® 1212-8 is a leadless, surface-mount package with an exposed copper drain pad on the bottom side. Its 3.3 mm × 3.3 mm footprint and 1.07 mm height support ultra-thin notebook designs while delivering thermal performance comparable to SO-8 packages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Four parallel source terminals reduce source inductance and improve current sharing in high-di/dt synchronous rectifiers. |
| 5, 6, 7, 8 | Drain (D) | Eight-terminal drain connection including large bottom-side copper pad; optimized for low-inductance, high-current PCB routing and thermal spreading. |
| 4 (top side) | Gate (G) | Single top-side gate terminal; positioned for short gate loop length to minimize EMI and oscillation risk in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| SkyFET® integration | Monolithic co-location of MOSFET and Schottky diode eliminates discrete diode placement, reduces BOM count, and cuts board area by ≥30 % vs. dual-component solutions. |
| PowerPAK® 1212-8 thermal design | Exposed drain pad achieves 2.4 °C/W RthJC, enabling 41 W power dissipation at TC = 25 °C-more than double that of TSSOP-8 equivalents. |
| 100 % Rg and UIS tested | Every unit undergoes gate resistance screening and unclamped inductive switching stress test, ensuring robustness against voltage spikes in buck converter freewheeling phases. |
| Low Qgd/Qg ratio | Qgd = 3.2 nC / Qg = 9.5 nC (4.5 V) yields 0.34 - improves hard-switching efficiency and reduces Miller-induced shoot-through risk. |
| Body diode trr | 18–35 ns - Fast reverse recovery minimizes cross-conduction loss during synchronous rectifier dead time, improving light-load efficiency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET with integrated Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7401DN-T1-GE3 | RDS(on) = 11.5 mΩ @ 4.5 V; same PowerPAK 1212-8 package; no integrated Schottky diode. | Requires external Schottky for synchronous rectification; higher total solution size and BOM count. | Select when discrete diode control or higher VDS margin (40 V) is needed; not drop-in for SkyFET®-dependent designs. |
| SiR872DP-T1-GE3 | 30 V, RDS(on) = 8.0 mΩ @ 10 V, 10.5 mΩ @ 4.5 V; PowerPAK® 1212-8; no integrated Schottky. | Lacks monolithic diode; superior RDS(on) but requires external diode and larger layout area for equivalent function. | Choose for highest efficiency in gate-driven-only applications; avoid if SkyFET®-enabled simplicity or dead-time loss reduction is required. |
Compared with SIS782DN-T1-GE3, Si7401DN-T1-GE3 offers higher VDS headroom but adds external diode complexity, while SiR872DP-T1-GE3 improves conduction loss but sacrifices the integrated Schottky's dead-time optimization-making SIS782DN-T1-GE3 uniquely suited for compact, high-efficiency synchronous rectification where diode integration directly reduces system-level losses and layout area.

FAQ
What is the maximum continuous drain current rating for SIS782DN-T1-GE3 at 70 °C case temperature?
The SIS782DN-T1-GE3 is rated for 16 A continuous drain current at TC = 70 °C, as specified in the Absolute Maximum Ratings table. This rating reflects derating from the 16 A value at TC = 25 °C and is validated under steady-state thermal conditions with proper PCB copper area. The SIS782DN-T1-GE3 maintains this current capability due to its low RthJC of 2.4 °C/W, enabling efficient heat transfer to the board.
Does SIS782DN-T1-GE3 require an external Schottky diode for synchronous rectification?
No, the SIS782DN-T1-GE3 does not require an external Schottky diode because it integrates a monolithic SkyFET® Schottky diode on the same die as the MOSFET. This integrated diode provides VSD = 0.44–0.55 V at 2 A and trr = 18–35 ns, eliminating external diode placement and associated layout parasitics. The SIS782DN-T1-GE3 is designed to operate as a complete synchronous rectifier switch without additional diode components.
What is the gate threshold voltage range for SIS782DN-T1-GE3, and how does it affect 4.5 V gate drive compatibility?
The gate threshold voltage (VGS(th)) for SIS782DN-T1-GE3 is specified from 1.0 V to 2.3 V at ID = 250 μA. This low and tightly bounded range ensures reliable turn-on with standard 4.5 V logic-level gate drivers, even under worst-case process and temperature variations. The SIS782DN-T1-GE3 achieves full enhancement and low RDS(on) (12.0 mΩ max) at 4.5 V, making it fully compatible with common PWM controller outputs.
How does the PowerPAK® 1212-8 package of SIS782DN-T1-GE3 improve thermal performance compared to TSSOP-8?
The PowerPAK® 1212-8 package of SIS782DN-T1-GE3 achieves RthJC = 2.4 °C/W (typical), which is over 20× better than typical TSSOP-8 packages (~52 °C/W). Its exposed copper drain pad provides a direct thermal path to the PCB, reducing junction-to-board resistance and enabling >25 W power dissipation with minimal copper area. The SIS782DN-T1-GE3 leverages this to sustain 16 A continuously where TSSOP-8 alternatives would thermally saturate.
Is SIS782DN-T1-GE3 suitable for use in automotive infotainment power supplies?
The SIS782DN-T1-GE3 is not qualified for automotive applications per AEC-Q101 and lacks automotive-grade qualification documentation. Its operating junction temperature range (–50 to +150 °C) meets some automotive ambient requirements, but Vishay specifies it for computing and industrial power applications. For automotive infotainment, designers should select AEC-Q101-qualified alternatives. The SIS782DN-T1-GE3 remains appropriate for commercial notebook and industrial DC-DC systems.
