Product details

Overview

UPA2732T1A-E1-AY from Renesas Electronics is a P-channel power MOSFET designed for Li-ion battery protection and power management in notebook computers. It delivers R_DS(on) = 3.7 mΩ max at V_GS = −10 V / I_D = −20 A, supports −30 V V_DSS, and features built-in gate protection diode in an 8-pin HVSON package.

For engineers reviewing the UPA2732T1A-E1-AY datasheet, UPA2732T1A-E1-AY pinout, UPA2732T1A-E1-AY application, or UPA2732T1A-E1-AY equivalent, key selection criteria include low-voltage gate drive capability (R_DS(on)2 = 6.7 mΩ @ V_GS = −4.5 V), avalanche energy rating (E_AS = 40 mJ), and surface-mount thermal performance on standard FR-4 PCBs.

Technical Context

This device operates as a high-side load switch in battery protection IC subsystems, where its negative threshold voltage (V_GS(off) = −1.0 to −2.5 V) enables direct control by system logic without level-shifting. Its low C_iss (3280 pF typ.) and fast switching (t_d(off) = 680 ns) support efficient pulsed operation in overcurrent and short-circuit response circuits.

The integrated body diode (V_F(S-D) = 0.85–1.2 V @ I_F = 40 A) provides reverse-current blocking during charge/discharge transitions, while the 8-pin HVSON package (5.15 × 6.0 mm) places all three source pins (1–3) and four drain pins (5–8) on opposing edges to minimize current loop inductance and improve thermal spreading.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V - Maximum drain-source blocking voltage for Li-ion battery stack (≤12.6 V) with safety margin.
R_DS(on)1	3.7 mΩ max @ V_GS = −10 V - Enables ≤0.74 W conduction loss at −20 A DC, critical for thermal budget in thin notebooks.
R_DS(on)2	6.7 mΩ max @ V_GS = −4.5 V - Supports logic-level gate drive from 5 V or 3.3 V controllers without external driver.
E_AS	40 mJ - Withstands single-pulse avalanche events during battery short-circuit transients without failure.
C_iss	3280 pF typ. - Low input capacitance reduces gate drive power and speeds up turn-on in protection IC timing loops.
T_ch max	150 °C - Channel temperature limit compatible with JEDEC JESD22-A103 reflow profiles and long-term reliability at 85 °C ambient.

Pinout & Package

Package: 8-pin HVSON (5.15 mm × 6.0 mm × 1.0 mm max), exposed drain pad for thermal conduction to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Common source connection; low-inductance parallel routing required for high di/dt battery fault currents.
4	Gate	Control terminal; requires external RC snubber if driven by high-impedance protection IC outputs.
5, 6, 7, 8	Drain	High-current drain path; pins 5–8 are internally bonded to the exposed thermal pad for PCB heat sinking.

Key Features

Feature	Design Value
Low R_DS(on) at −4.5 V	6.7 mΩ max enables direct interface with 5 V/3.3 V battery protection ICs without gate boosting.
Built-in gate protection diode	ESD-rated diode between gate and source prevents latch-up during handling and board assembly.
Avalanche-rated operation	Rated for single-pulse E_AS = 40 mJ ensures robustness against inductive kickback in battery disconnect events.
Optimized for Li-ion systems	Specified parameters (e.g., V_GS(off), Q_G = 133 nC) align with JEITA EM-1101 battery pack protection timing requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2301DS-T1-E3	R_DS(on) = 115 mΩ @ −4.5 V; smaller SOT-23 package; lower I_D(DC) = −2.7 A.	Suitable only for sub-3 A loads; not rated for avalanche or high-pulse battery faults.	Select when space-constrained and power dissipation <0.3 W; avoid in primary battery protection paths.
IRF7425PBF	R_DS(on) = 29 mΩ @ −4.5 V; SO-8 package; higher C_iss = 1600 pF; no specified E_AS.	Lacks avalanche rating and gate protection diode; requires external ESD protection in portable designs.	Prefer for cost-sensitive industrial supplies where battery-level fault robustness is not required.

Compared with Si2301DS-T1-E3 and IRF7425PBF, the UPA2732T1A-E1-AY offers superior conduction efficiency at logic-level gate drive, integrated ESD protection, and certified avalanche capability-making it uniquely suited for primary Li-ion protection switches where reliability under fault conditions is non-negotiable.

FAQ

What is the maximum continuous drain current rating for UPA2732T1A-E1-AY?

The UPA2732T1A-E1-AY has a maximum continuous drain current (I_D(DC)) of −40 A at T_A = 25°C on a standard glass epoxy board (25.4 mm × 25.4 mm × 0.8 mm). Derating applies above 25°C ambient; at 85°C, usable I_D(DC) drops to approximately −25 A per the SOA curve. This rating assumes proper PCB copper area for thermal conduction from the exposed drain pad.

Does UPA2732T1A-E1-AY require an external gate resistor for stability?

Yes, UPA2732T1A-E1-AY benefits from an external gate resistor (typically 10–47 Ω) to dampen ringing caused by its low C_iss and high dV/dt during switching. The datasheet specifies t_d(off) and t_f test conditions using R_G = 10 Ω; omitting this resistor may cause oscillation or shoot-through in high-speed protection circuits.

Is UPA2732T1A-E1-AY RoHS compliant and lead-free?

Yes, UPA2732T1A-E1-AY is RoHS compliant and lead-free. The "E1-AZ" suffix explicitly denotes Pb-free construction (no lead in external electrodes), meeting EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking requirements.

Can UPA2732T1A-E1-AY be used in avalanche mode repeatedly?

No, UPA2732T1A-E1-AY is rated for single-pulse avalanche only (E_AS = 40 mJ, I_AS = −20 A). Repeated avalanche operation is not characterized or guaranteed and may degrade channel integrity. System design must ensure fault conditions are cleared before subsequent cycles-e.g., via fuse blow or controller lockout after first event.

What is the thermal resistance from channel to ambient for UPA2732T1A-E1-AY?

The transient thermal resistance (R_th(ch-A)) of UPA2732T1A-E1-AY is 83.3 °C/W when mounted on a 25.4 mm × 25.4 mm × 0.8 mm glass epoxy board. Steady-state R_th(ch-A) is higher; for continuous operation, use the derating curve in the datasheet to determine safe I_D at target T_A. The low R_th(ch-C) = 1.5 °C/W indicates excellent conduction to the PCB copper layer.
