Product details
Overview
SIR464DP-T1-GE3 from Vishay Siliconix is an N-channel 30-V TrenchFET® Power MOSFET in PowerPAK SO-8 package, delivering 50 A continuous drain current at TC = 25 °C, RDS(on) = 0.0031 Ω at VGS = 10 V, and Qg = 26.5 nC (typ.) at VGS = 4.5 V. It serves as a high-efficiency low-side switch in DC/DC converters for notebook and server power stages.
For engineers reviewing the SIR464DP-T1-GE3 datasheet, SIR464DP-T1-GE3 pinout, SIR464DP-T1-GE3 application, or SIR464DP-T1-GE3 equivalent, key selection criteria include its 30-V VDS, ultra-low RDS(on) at 4.5-V drive, 100% Rg and UIS tested reliability, thermal performance matching DPAK, and compatibility with standard SO-8 PCB footprints.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for synchronous buck converter low-side operation. Its gate charge profile supports fast switching with td(on) = 18 ns and tf = 9 ns (VGEN = 10 V), while body diode characteristics (VSD = 0.72 V at IS = 3 A, trr = 33 ns) enable efficient freewheeling in hard-switched topologies.
The device features a leadless PowerPAK SO-8 package with exposed drain pad for direct thermal conduction to PCB copper. Its RthJC = 1.2 °C/W (typ.) enables high-power density designs, and it is rated for operation from –55 °C to +150 °C junction temperature with ±20-V gate-source voltage tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 24-V input rails and 12-V output stages in point-of-load converters. |
| RDS(on) | 0.0031 Ω at VGS = 10 V - Enables <1.5 W conduction loss at 60 A, critical for high-current CPU/GPU VRMs. |
| ID (cont.) | 50 A at TC = 25 °C - Package-limited current rating suitable for multi-phase low-side switching in servers. |
| Qg | 26.5 nC at VGS = 4.5 V - Low gate charge allows efficient drive from standard PWM controllers without external buffers. |
| RthJC | 1.2 °C/W (typ.) - Thermal resistance equivalent to DPAK, enabling high-power dissipation on compact PCBs with minimal heatsinking. |
| VGS(th) | 1.2–2.5 V - Ensures robust turn-on with 3.3-V or 5-V gate drivers and immunity to noise-induced false triggering. |
| EAS | 80 mJ - Avalanche energy rating supports reliable operation under inductive load switching stress and transient overcurrent events. |
Pinout & Package
PowerPAK SO-8 is a leadless surface-mount package with 8 terminals arranged in standard SO-8 footprint (6.15 mm × 5.15 mm), featuring an exposed bottom-side drain pad for enhanced thermal transfer. Pin 1 is Gate, Pins 2–4 and 6–8 are Source, and Pins 5 and 7 are Drain (dual-drain configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 0–10 V logic-level drive; requires <2.2 Ω gate resistance to limit ringing per datasheet. |
| 2,3,4,6,8 (S) | Source | Power return path; all five pins internally connected to source metallization for low-inductance grounding in high-dI/dt applications. |
| 5,7 (D) | Drain | Main power input; dual-drain layout distributes current and reduces package inductance; connects directly to PCB copper pour for thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 30-V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiR462DP-T1-GE3 | RDS(on) = 0.0038 Ω at VGS = 4.5 V (vs. 0.0031 Ω); same package, pinout, and VDS. | Higher conduction loss at low gate drive; suitable where 4.5-V drive margin is sufficient and cost optimization is prioritized. | Select SiR462DP-T1-GE3 only if system efficiency targets allow ~22% higher I²R loss at 10-A load. |
| SiR466DP-T1-GE3 | RDS(on) = 0.0026 Ω at VGS = 10 V (vs. 0.0031 Ω); identical thermal specs and footprint. | Lower RDS(on) improves conduction efficiency but increases Qg to 32 nC, raising switching loss at high frequencies. | Choose SiR466DP-T1-GE3 when conduction loss dominates (e.g., <500 kHz operation) and gate drive capability supports higher Qg. |
Compared with SIR464DP-T1-GE3, SiR462DP-T1-GE3 trades lower cost for higher RDS(on) at 4.5 V, while SiR466DP-T1-GE3 delivers lower conduction loss at the expense of increased gate charge-making SIR464DP-T1-GE3 the balanced choice for 4.5–10 V drive, 500 kHz–1 MHz operation, and thermal-constrained server/notebook designs.

FAQ
What is the maximum continuous drain current rating for SIR464DP-T1-GE3 at 70 °C case temperature?
The SIR464DP-T1-GE3 supports 50 A continuous drain current at TC = 70 °C, as specified in the Absolute Maximum Ratings table. This rating is package-limited and remains unchanged from the 25 °C value due to the PowerPAK SO-8's superior thermal design, unlike conventional SO-8 devices that derate significantly above 25 °C. The 50-A rating applies under steady-state conditions with proper PCB copper thermal management.
Does SIR464DP-T1-GE3 support 3.3-V gate drive in practical applications?
Yes, SIR464DP-T1-GE3 is fully compatible with 3.3-V gate drive. Its VGS(th) range of 1.2–2.5 V ensures reliable turn-on, and RDS(on) = 0.0038 Ω at VGS = 4.5 V (and 0.0031 Ω at 10 V) confirms strong enhancement-mode behavior at low voltages. Real-world designs using 3.3-V controllers achieve <5 mΩ effective on-resistance with appropriate layout and thermal design, making SIR464DP-T1-GE3 suitable for logic-level drive architectures.
How does the PowerPAK SO-8 package of SIR464DP-T1-GE3 compare thermally to a standard SO-8 MOSFET?
The PowerPAK SO-8 package in SIR464DP-T1-GE3 delivers RthJC = 1.2 °C/W (typ.), matching DPAK performance and offering ~13× better junction-to-case thermal resistance than a standard SO-8 (16 °C/W). When mounted on the same PCB, this reduces die temperature rise by ~40 °C at 2.7 W dissipation-keeping RDS(on) stable and enabling higher current handling without heatsinks. The exposed drain pad provides direct thermal conduction to PCB copper, unlike leaded SO-8 packages.
Is SIR464DP-T1-GE3 pin-compatible with standard SO-8 footprints?
Yes, SIR464DP-T1-GE3 uses the PowerPAK SO-8 package, which maintains identical outline dimensions (6.15 mm × 5.15 mm), pin count (8), and pin spacing (1.27 mm) as the standard SO-8. Its pinout (G-S-S-S-D-S-D-S) aligns with industry-standard SO-8 low-side MOSFET layouts, allowing drop-in replacement on existing boards-though optimal thermal performance requires extending the drain pad copper area per Vishay Application Note AN821.
What is the typical total gate charge (Qg) of SIR464DP-T1-GE3 at 4.5-V gate drive, and why does it matter?
The typical total gate charge (Qg) of SIR464DP-T1-GE3 is 26.5 nC at VGS = 4.5 V and VDS = 15 V. This low Qg minimizes gate driver power consumption and switching transition time, enabling efficient operation at high frequencies (≥1 MHz) without excessive gate drive strength. In server VRMs, it reduces driver IC stress and allows use of integrated controller FET drivers instead of external buffers-simplifying BOM and layout.
