Product details

Overview

UPA2706GR-E1-A from Renesas Electronics is an N-channel power MOSFET designed for high-efficiency DC/DC converters in notebook computers. It delivers R_DS(on) = 15 mΩ max at V_GS = 10 V / I_D = 5.5 A, supports ±11 A DC drain current, and features low input capacitance (C_iss = 660 pF typ) in a Power SOP8 surface-mount package.

For engineers reviewing the UPA2706GR-E1-A datasheet, UPA2706GR-E1-A pinout, UPA2706GR-E1-A application, or UPA2706GR-E1-A equivalent, key selection criteria include gate threshold compatibility with 4.5 V logic-level drive, avalanche energy rating (E_AS = 12.1 mJ), body diode reverse recovery performance (t_rr = 25 ns), and thermal derating on ceramic substrates.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in synchronous buck topologies. Its dual R_DS(on) specification (15 mΩ @ 10 V, 22.5 mΩ @ 4.5 V) confirms robust operation under both standard and logic-level gate drive conditions.

The integrated body diode exhibits VF(S-D) = 0.84 V at IF = 11 A and t_rr = 25 ns with di/dt = 100 A/µs - enabling efficient freewheeling in high-frequency converter stages without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - supports input rails up to 24 V nominal with 25% margin for transient spikes in notebook power rails.
R_DS(on)1	15 mΩ max @ V_GS = 10 V / I_D = 5.5 A - enables <100 mW conduction loss at 5.5 A, critical for thermally constrained laptop PCBs.
R_DS(on)2	22.5 mΩ max @ V_GS = 4.5 V / I_D = 5.5 A - ensures reliable turn-on with standard 5 V or 3.3 V controller outputs.
C_iss	660 pF typ @ V_DS = 10 V - reduces gate drive power and enables >1 MHz switching without excessive driver stress.
E_AS	12.1 mJ - withstands single-pulse inductive energy events common during load transients in VRMs.
t_rr	25 ns - minimizes reverse recovery losses and EMI generation in synchronous rectification mode.
Q_G	7.1 nC - balances switching speed and gate driver complexity for 500 kHz–2 MHz converter designs.

Pinout & Package

UPA2706GR-E1-A is housed in a Power SOP8 (also known as PSOP8 or SOP-8L) package with exposed drain pad for enhanced thermal dissipation. The package measures 6.0 mm × 4.4 mm × 1.8 mm (max) and is rated for T_ch = 150°C.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Common return path for load current; internally bonded to substrate; connects to power ground plane.
4	Gate	Control terminal requiring <7.1 nC charge for full enhancement; sensitive to ESD (protected by internal diode).
5, 6, 7, 8	Drain	Main power output node; pins 5–8 and exposed bottom pad form low-inductance, high-current drain connection.

Key Features

Feature	Design Value
Logic-level gate drive support	Guaranteed R_DS(on) ≤ 22.5 mΩ at V_GS = 4.5 V - eliminates need for gate boosters in 5 V/3.3 V controller designs.
Low gate charge	Q_G = 7.1 nC - reduces driver power loss and enables clean, fast transitions even with small SOT-23 drivers.
Fast body diode recovery	t_rr = 25 ns - suppresses shoot-through risk and voltage overshoot during dead-time in synchronous buck stages.
Avalanche-rated operation	E_AS = 12.1 mJ - provides inherent ruggedness against inductive switching faults without external snubbers.

Applications

High-Efficiency Notebook CPU VRM	USB-C PD Buck Converter

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
Si2302DS-T1-E3	R_DS(on) = 35 mΩ @ 4.5 V; SOT-23 package; lower current rating (I_D(DC) = 2.9 A).	Not suitable for >3 A continuous loads; limited thermal mass for sustained 2 W dissipation.	Select only for ultra-low-cost, low-power auxiliary rails where size outweighs efficiency.
IRLML6344TRPBF	R_DS(on) = 22 mΩ @ 4.5 V; same Power SO-8 footprint; higher Q_G (12.5 nC) and C_iss (920 pF).	Slower switching and higher gate drive loss; requires stronger driver for >1 MHz operation.	Acceptable for 300–500 kHz designs where gate drive capability exceeds 1 A peak.

Compared with Si2302DS-T1-E3 and IRLML6344TRPBF, UPA2706GR-E1-A offers superior R_DS(on)/Q_G ratio and proven avalanche ruggedness - making it optimal for thermally demanding, high-frequency notebook and industrial DC/DC applications where reliability and efficiency are co-prioritized.

FAQ

What is the maximum continuous drain current rating for UPA2706GR-E1-A?

The UPA2706GR-E1-A is rated for ±11 A DC drain current at T_A = 25°C when mounted on a 1200 mm² ceramic substrate. Derating applies above 25°C ambient; at 75°C, usable current drops to approximately ±6.5 A based on the published thermal resistance curve and power limit.

Does UPA2706GR-E1-A support 3.3 V gate drive in practice?

UPA2706GR-E1-A does not guarantee full enhancement at 3.3 V gate drive. Its R_DS(on)2 spec is defined at V_GS = 4.5 V (22.5 mΩ max). At 3.3 V, R_DS(on) rises significantly - typical data shows ~45 mΩ - increasing conduction loss by >2×. Use only with 4.5 V or higher gate drive for optimal performance.

Is UPA2706GR-E1-A RoHS compliant and lead-free?

Yes, UPA2706GR-E1-A complies with EU RoHS Directive requirements. Renesas confirms lead-free termination and halogen-free packaging for this part, consistent with its manufacturing date post-2006 and alignment with industry environmental standards cited in official product change notices.

What is the purpose of the internal gate-source protection diode in UPA2706GR-E1-A?

The internal gate-source diode in UPA2706GR-E1-A serves as an ESD protection element, clamping transient voltages to prevent gate oxide breakdown. However, Renesas explicitly states that external protection remains mandatory if overvoltage exceeding ±20 V may occur - the internal diode alone is insufficient for system-level surge immunity.

Can UPA2706GR-E1-A be used in avalanche mode repeatedly?

No. UPA2706GR-E1-A is rated for single-pulse avalanche only (E_AS = 12.1 mJ, I_AS = 11 A). Repetitive avalanche operation is not characterized or guaranteed. Designers must avoid conditions causing repeated inductive energy dumping into the device - use snubbers, clamp circuits, or topology changes to prevent recurrence.
