Product details

Overview

UPA2742GR-E1-AT from Renesas Electronics is an N-channel power MOSFET designed for high-efficiency DC-DC power management in notebook computers, featuring R_DS(on)1 = 4.8 mΩ (V_GS = 10 V, I_D = 9 A), V_DSS = 35 V, and I_D(DC) = ±17 A in a Power SOP8 package.

For engineers reviewing the UPA2742GR-E1-AT datasheet, UPA2742GR-E1-AT pinout, UPA2742GR-E1-AT application, or UPA2742GR-E1-AT equivalent, this device is selected for low-R_DS(on) synchronous rectification, compact board space, and robust avalanche capability (E_AS = 28.9 mJ) in portable computing power stages.

Technical Context

This MOSFET operates as a main or synchronous switch in buck converters and load switches, leveraging its low gate charge (Q_G = 43 nC) and fast switching (t_d(on) = 27 ns, t_f = 41 ns) to minimize conduction and switching losses at high frequencies up to 1 MHz.

Its built-in gate-source protection diode supports ESD robustness, while the body diode exhibits V_F(S-D) = 1.2 V (I_F = 17 A) and t_rr = 37 ns-enabling efficient freewheeling in non-overlap-controlled topologies without external Schottky supplementation.

Key Specifications

R_DS(on)1	4.8 mΩ max @ V_GS = 10 V, I_D = 9 A - Enables <1 W conduction loss at 9 A continuous current
Q_G	43 nC - Low gate drive energy requirement compatible with standard PWM controllers
E_AS	28.9 mJ - Single-pulse avalanche energy rating supports reliable operation under inductive switching stress
C_iss	4600 pF typ @ V_DS = 10 V - Input capacitance impacts gate driver sizing and turn-on speed
t_r/t_f	35 ns / 41 ns - Fast edge rates reduce switching transition time and associated losses
T_ch max	150 °C - Channel temperature limit defines thermal derating envelope on FR-4 PCB

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
Si7850DP-T1-GE3	R_DS(on) = 4.5 mΩ @ 10 V but higher C_iss (5200 pF); no integrated gate Zener	Requires external gate protection; better suited for fixed 12 V gate drive systems	Select when lower R_DS(on) outweighs need for integrated ESD protection
IRF7478PBF	R_DS(on) = 5.2 mΩ @ 10 V; SO-8 package with standard pinout; no avalanche rating specified	Lacks E_AS spec and gate protection; requires careful layout for reliability	Choose for cost-sensitive designs where avalanche stress is absent and external protection is implemented

Compared with Si7850DP-T1-GE3 and IRF7478PBF, the UPA2742GR-E1-AT delivers verified avalanche ruggedness and gate-integrated ESD protection in the same Power SOP8 footprint-critical for unattended notebook power stage reliability without added BOM components.

FAQ

What is the maximum continuous drain current rating for UPA2742GR-E1-AT?

The UPA2742GR-E1-AT has a maximum continuous drain current (I_D(DC)) of ±17 A at T_A = 25°C when mounted on a 25.4 mm × 25.4 mm × 0.8 mm FR-4 PCB. Derating applies above 25°C ambient, with thermal resistance R_th(ch-A) = 114°C/W defining the slope. This rating supports sustained operation in notebook CPU/GPU VRM high-side positions.

Does UPA2742GR-E1-AT include integrated gate protection?

Yes, the UPA2742GR-E1-AT integrates a gate-to-source Zener diode for ESD protection, rated for ±20 V gate voltage clamping. The datasheet explicitly states this feature under "Features" and notes it serves as an ESD protector-though external protection remains recommended if overvoltage transients exceed ratings. This design eliminates the need for discrete gate Zeners in most notebook power stage layouts.

What is the typical input capacitance (C_iss) of UPA2742GR-E1-AT and how does it affect gate drive design?

The UPA2742GR-E1-AT has a typical input capacitance (C_iss) of 4600 pF at V_DS = 10 V and V_GS = 0 V. This value directly determines required gate drive current for target slew rates: e.g., achieving 10 V/ns dV/dt demands ~46 mA peak drive. Gate drivers must be sized accordingly to avoid slow turn-on and increased switching loss in high-frequency VRMs.

Can UPA2742GR-E1-AT be used in avalanche-mode operation?

Yes, the UPA2742GR-E1-AT is characterized for single-pulse avalanche operation with I_AS = 17 A and E_AS = 28.9 mJ under defined test conditions (T_ch = 25°C, V_DD = 17.5 V, L = 100 μH, R_G = 25 Ω). This ruggedness allows safe operation during inductive switching faults in notebook power stages without immediate failure, supporting robust system-level design.

What is the RoHS status and lead plating specification for UPA2742GR-E1-AT?

The UPA2742GR-E1-AT is RoHS compliant with pure tin (Sn) lead plating, containing no Pb in external electrodes or other parts. The ordering code "-E1-AT" explicitly denotes Pb-free packaging per the datasheet's Ordering Information table. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow processes.
