Product details
Overview
UPA2751GR-E1-A from Renesas Electronics is an asymmetrical dual N-channel power MOSFET in Power SOP8 package, designed for synchronous rectification and high-efficiency DC/DC converters in notebook computers. It features channel 1 RDS(on) ≤ 21.0 mΩ at VGS = 4.5 V / ID = 4.5 A, channel 2 RDS(on) ≤ 35.0 mΩ under same conditions, and integrated gate-source protection diodes per channel.
For engineers reviewing the UPA2751GR-E1-A datasheet, UPA2751GR-E1-A pinout, UPA2751GR-E1-A application, or UPA2751GR-E1-A equivalent, key selection criteria include asymmetric on-resistance pairing, avalanche energy ratings (EAS = 8.1 mJ CH1 / 6.4 mJ CH2), body diode reverse recovery time (trr = 34 ns CH1 / 28 ns CH2), and thermal resistance (Rth(ch–A) = 73.5 °C/W).
Technical Context
This dual-channel MOSFET integrates two discrete N-channel silicon power transistors with independent gate, source, and drain terminals on a single die. Channel 1 is optimized for higher current handling (ID(DC) = ±9.0 A) and lower on-resistance, while Channel 2 provides complementary switching with tighter gate charge (QG = 10 nC) and faster switching (td(off) = 25 ns).
The device employs planar V-groove MOSFET technology with built-in gate-source ESD protection diodes. Its asymmetric design enables use in primary-side/secondary-side configurations of buck or multiphase converters, where differing conduction and switching requirements exist between channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for both channels; suitable for 12 V and 19 V input DC/DC stages. |
| RDS(on)1 @ 4.5 V | ≤21.0 mΩ - Low conduction loss in main power path (CH1), enabling high efficiency at 4.5 A load. |
| RDS(on)2 @ 4.5 V | ≤35.0 mΩ - Higher but optimized on-resistance for auxiliary/synchronous rectifier path (CH2). |
| QG (CH1) | 21 nC - Gate drive energy requirement for full turn-on; impacts driver sizing and switching loss. |
| trr (CH1) | 34 ns - Fast body diode recovery critical for minimizing shoot-through and ringing in synchronous buck topologies. |
| EAS (CH1) | 8.1 mJ - Single-pulse avalanche energy rating; supports robust operation during inductive switching transients. |
| PT (2 unit) | 2.0 W - Total package power dissipation at TA = 25°C on 2000 mm² ceramic substrate; defines thermal derating envelope. |
Pinout & Package
UPA2751GR-E1-A is housed in a surface-mount Power SOP8 (Small Outline Package, 8-pin) with exposed drain pad for thermal enhancement. Package dimensions: 6.0 × 4.4 × 1.8 mm (L × W × H), lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Source 1 | Power return node for Channel 1; electrically tied to exposed drain pad via internal substrate connection. |
| 3 | Gate 1 | Control input for Channel 1; requires gate driver capable of ±20 V rating and sufficient peak current. |
| 4, 5 | Drain 1 | Main power output node for Channel 1; connected to exposed drain pad for low-inductance, high-current routing. |
| 6 | Gate 2 | Independent control input for Channel 2; allows asynchronous or phase-shifted gate timing. |
| 7, 8 | Source 2 / Drain 2 | Source terminal for Channel 2 (pins 7,8); pins 4,5 are dedicated Drain 1 only - no shared drain/source between channels. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric dual-channel architecture | Enables optimized primary/secondary switching in compact DC/DC converters without external component matching. |
| Built-in G-S protection diode (per channel) | Provides ESD immunity up to human-body model (HBM) level; reduces need for external TVS on gate lines. |
| Low Ciss (CH2: 480 pF) | Minimizes gate drive power and improves high-frequency switching efficiency in secondary-side applications. |
| Fast tr/tf (CH2: 6.2 ns / 5.8 ns) | Reduces switching transition losses and EMI generation in high-frequency (>500 kHz) converter designs. |
| 150°C channel temperature rating | Supports operation in thermally constrained notebook chassis environments with minimal derating. |
Applications
| High-Efficiency Notebook DC/DC Converter | Synchronous Buck Regulator |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7852DP-T1-GE3 | Symmetric RDS(on) (12 mΩ/12 mΩ @ 10 V); no integrated G-S diode; SO-8 package. | Requires external gate protection; better suited for matched dual-switch topologies like half-bridge drivers. | Select when symmetry and lowest possible RDS(on) outweigh need for integrated ESD protection and asymmetric optimization. |
| IPG20N04S4L-05 | Single-channel 40 V TrenchFET; RDS(on) = 4.5 mΩ @ 10 V; TO-252 package; no dual-channel capability. | Cannot replace dual-channel function without board redesign; higher thermal resistance (Rth(j–amb) = 60 °C/W). | Choose only if redesigning for discrete channel separation and higher voltage margin is acceptable. |
Compared with Si7852DP-T1-GE3 and IPG20N04S4L-05, the UPA2751GR-E1-A uniquely delivers asymmetric channel optimization, integrated gate protection, and Power SOP8 thermal performance-making it irreplaceable in space-constrained, high-efficiency dual-rail notebook DC/DC designs without layout changes.

FAQ
What is the maximum continuous drain current rating for each channel of the UPA2751GR-E1-A?
The UPA2751GR-E1-A specifies ±9.0 A DC for Channel 1 and ±8.0 A DC for Channel 2 at TA = 25°C with proper PCB thermal management. These values assume mounting on a 2000 mm² ceramic substrate; actual usable current depends on ambient temperature, copper area, and airflow. Derating curves in the datasheet confirm 50% current reduction at TA = 100°C.
Does the UPA2751GR-E1-A support 4.5 V gate drive for both channels?
Yes - the UPA2751GR-E1-A is fully characterized for 4.5 V gate drive: Channel 1 RDS(on)2 ≤ 21.0 mΩ and Channel 2 RDS(on)2 ≤ 35.0 mΩ are guaranteed at VGS = 4.5 V and respective ID conditions. This enables direct interface with 5 V logic-level controllers without level-shifting circuitry.
Is the UPA2751GR-E1-A pin-compatible with other Power SOP8 dual MOSFETs?
No documented pin-to-pin compatibility exists between the UPA2751GR-E1-A and other Power SOP8 dual MOSFETs. Its pin assignment (e.g., pins 4/5 = Drain 1 only; pins 7/8 = Source 2 only) is unique to this asymmetrical configuration. Board-level substitution requires verification of terminal mapping, thermal pad connectivity, and gate drive sequencing.
What is the significance of the "E1-A" suffix in UPA2751GR-E1-A?
The "E1-A" suffix denotes the tape-and-reel packaging variant per Renesas' ordering convention: E1 indicates embossed carrier tape (8 mm width), and "A" specifies standard packing quantity (2,500 pcs/reel). This format is optimized for SMT placement equipment and qualifies for automated manufacturing flow.
Can the UPA2751GR-E1-A be used in automotive applications?
The UPA2751GR-E1-A carries a "Standard" quality grade per Renesas documentation, intended for computers, office equipment, and consumer electronics-not automotive systems. It lacks AEC-Q101 qualification, extended temperature validation, or automotive-specific reliability testing. Use in automotive contexts requires formal qualification by the end customer and written consent from Renesas.
