Product details
Overview
UPA2746UT1A-E2-AY from Renesas Electronics is an N-channel power MOSFET designed for high-efficiency DC/DC converter primary-side switching, featuring 30 V VDSS, 3.0 mΩ RDS(on) at VGS = 10 V / ID = 45 A, and 83 W PT3 at TC = 25°C in an 8-pin HVSON package.
For engineers reviewing the UPA2746UT1A-E2-AY datasheet, UPA2746UT1A-E2-AY pinout, UPA2746UT1A-E2-AY application, or UPA2746UT1A-E2-AY equivalent, key selection criteria include low RDS(on) at 4.5 V gate drive, avalanche energy rating (EAS = 160 mJ), thermal resistance (Rth(ch–C) = 1.5°C/W), and RoHS/halogen-free compliance for compact power stages.
Technical Context
This device implements a trench-gate, silicon-based N-channel MOSFET architecture optimized for synchronous rectification and buck converter high-side switching. It supports pulse operation up to 190 A (ID(pulse)) with controlled turn-on delay (26 ns) and fall time (15 ns), enabling high-frequency (>500 kHz) power conversion.
Its body diode exhibits VF(S–D) = 0.83 V at IF = 45 A and fast reverse recovery (trr = 37 ns, Qrr = 35 nC), reducing switching losses in hard-commutated topologies. The 8-pin HVSON package integrates a thermally enhanced drain-exposed pad for direct PCB heat spreading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12 V–24 V input DC/DC stages |
| RDS(on)1 | 3.0 mΩ max @ VGS = 10 V, ID = 45 A - Enables <1.5 W conduction loss at full load |
| RDS(on)2 | 4.5 mΩ max @ VGS = 4.5 V, ID = 23 A - Supports logic-level gate drive in 3.3 V control systems |
| EAS | 160 mJ - Withstands single-pulse inductive energy without failure in unclamped inductive switching |
| Rth(ch–C) | 1.5°C/W - Allows >50 W continuous dissipation with minimal case-to-ambient delta-T under forced airflow |
| QG | 78 nC max @ VGS = 10 V - Determines gate driver current requirement for <100 ns switching transitions |
| tr/tf | 14 ns / 15 ns - Enables efficient operation above 1 MHz with reduced overlap loss |
Pinout & Package
The UPA2746UT1A-E2-AY uses an 8-pin HVSON (6051) surface-mount package with exposed drain thermal pad (5.4 mm × 6.0 mm footprint). Pin 1–3 are internally connected source terminals; pin 4 is gate; pins 5–8 are internally connected drain terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source node for internal parallel die; connects to low-side return path and gate driver reference |
| 4 | Gate | Control terminal requiring ≤±20 V drive; low QG enables fast edge rates with modest driver strength |
| 5, 6, 7, 8 | Drain | High-current drain connection with integrated thermal pad; must be soldered to large copper area for Rth(ch–C) performance |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4.5 V | 4.5 mΩ max enables use with standard 5 V or 3.3 V microcontroller GPIOs without level-shifting |
| Thin HVSON package | 1.0 mm max height allows integration into space-constrained DC/DC modules and POL converters |
| Avalanche-rated | Rated for 40 A single-pulse avalanche current and 160 mJ energy-supports robustness in flyback and LLC resonant designs |
| RoHS & halogen-free | Complies with EU RoHS Directive and JEDEC J-STD-609A Class 1 moisture sensitivity (MSL 1) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiR872DP-T1-GE3 | RDS(on) = 2.8 mΩ @ 10 V but higher QG (105 nC); 5×6 mm SO-8 package | Larger footprint; requires more gate drive power; better for lower-frequency, higher-current designs | Select when board space permits larger package and gate drive capability exceeds 2 A peak |
| IPB033N04LGATMA1 | RDS(on) = 3.3 mΩ @ 10 V; TO-263-3 package; higher Rth(j–c) = 2.0°C/W | Through-hole compatible; less suitable for ultra-thin or high-density layouts | Select when legacy through-hole assembly or higher single-pulse avalanche margin (220 mJ) is prioritized over profile |
Compared with SiR872DP-T1-GE3 and IPB033N04LGATMA1, the UPA2746UT1A-E2-AY delivers optimal balance of low-profile packaging, 4.5 V logic-level compatibility, and 1.5°C/W thermal resistance-making it preferred for space- and thermally constrained 500 kHz–1 MHz DC/DC converters where gate drive headroom is limited.

FAQ
What is the maximum continuous drain current rating for the UPA2746UT1A-E2-AY at 25°C case temperature?
The UPA2746UT1A-E2-AY supports a continuous drain current (ID(DC)) of ±45 A when the case temperature (TC) is maintained at 25°C. This rating assumes proper PCB copper area for thermal conduction and is directly tied to its 83 W total power dissipation (PT3) specification. Derating applies above 25°C per the datasheet's thermal curves.
Does the UPA2746UT1A-E2-AY support logic-level gate drive, and what is its RDS(on) at 4.5 V?
Yes, the UPA2746UT1A-E2-AY is specified for logic-level operation: its RDS(on)2 is guaranteed ≤4.5 mΩ at VGS = 4.5 V and ID = 23 A. This enables direct drive from 3.3 V or 5 V controllers without external level shifters, reducing system component count and layout complexity in compact DC/DC designs.
What is the thermal resistance from channel to case (Rth(ch–C)) for the UPA2746UT1A-E2-AY, and how should it be applied in layout?
The UPA2746UT1A-E2-AY has an Rth(ch–C) of 1.5°C/W, measured from channel junction to the exposed drain pad. To achieve this value, the 5.4 mm × 6.0 mm thermal pad must be fully soldered to ≥4 cm² of inner-layer copper pour connected via ≥8 thermal vias (0.3 mm diameter) to solid ground planes-per the recommended land pattern in the package drawing.
Is the UPA2746UT1A-E2-AY rated for avalanche energy, and what are the test conditions?
Yes, the UPA2746UT1A-E2-AY is avalanche-rated: it guarantees 160 mJ single-pulse avalanche energy (EAS) and 40 A single-pulse avalanche current (IAS). Testing follows JEDEC JESD24-1 conditions: starting Tch = 25°C, VDD = 15 V, L = 100 μH, RG = 25 Ω, and VGS transition from 20 V to 0 V-validating ruggedness in unclamped inductive switching events.
What is the gate charge (QG) of the UPA2746UT1A-E2-AY, and why does it matter for high-frequency operation?
The UPA2746UT1A-E2-AY has a total gate charge (QG) of 78 nC max at VGS = 10 V. This parameter directly determines required gate driver peak current (IDRV ≈ QG × fSW) and switching transition times. At 1 MHz, 78 nC demands ~78 mA average gate current-enabling clean, low-loss edges without excessive driver sizing in high-frequency DC/DC converters.
