Product details
Overview
UPA2732T1A-E1-AZ from Renesas Electronics is a P-channel power MOSFET designed for Li-ion battery protection circuits and notebook computer power management. It delivers RDS(on)1 = 3.7 mΩ max at VGS = −10 V / ID = −20 A, supports −30 V VDSS, −40 A DC drain current, and features built-in gate protection diode in an 8-pin HVSON package.
For engineers reviewing the UPA2732T1A-E1-AZ datasheet, UPA2732T1A-E1-AZ pinout, UPA2732T1A-E1-AZ application, or UPA2732T1A-E1-AZ equivalent, key selection criteria include low-voltage gate drive capability (RDS(on)2 = 6.7 mΩ @ VGS = −4.5 V), avalanche energy rating (EAS = 40 mJ), and thermal performance on standard FR-4 PCBs.
Technical Context
This device operates as a synchronous or standalone high-side load switch in battery protection IC subsystems, where fast turn-off (td(off) = 680 ns) and low gate charge (QG = 133 nC) enable efficient switching control. Its body diode exhibits VF(S-D) = 0.85–1.2 V at 40 A and trr = 88 ns, supporting bidirectional current handling in charge/discharge paths.
The MOSFET integrates an internal gate-source ESD protection diode and is characterized for operation up to Tch = 150 °C. Its safe operating area (SOA) is defined for single-pulse conditions up to 10 s with derating above 25 °C ambient, and it meets Standard-grade quality requirements for consumer electronics applications.

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 |
|---|---|---|---|
| Si2301DDS-T1-GE3 | RDS(on) = 115 mΩ @ −4.5 V; smaller SOT-23 package; no avalanche rating | Lower current (<3 A), space-constrained designs where ESD protection suffices | Choose only for sub-5 A loads with relaxed SOA and thermal requirements |
| AO3401A | RDS(on) = 52 mΩ @ −4.5 V; TO-236 package; higher Ciss (870 pF) | Cost-sensitive consumer devices with moderate switching frequency (<1 MHz) | Prefer when layout area allows larger footprint and gate drive strength is limited |
Compared with Si2301DDS-T1-GE3 and AO3401A, UPA2732T1A-E1-AZ offers superior conduction efficiency (3.7 mΩ vs. >50 mΩ), higher current capability (−40 A vs. <5 A), and certified avalanche ruggedness - making it uniquely suitable for high-power battery protection where thermal margin and fault robustness are critical.

FAQ
What is the maximum continuous drain current rating for UPA2732T1A-E1-AZ?
The UPA2732T1A-E1-AZ has a DC drain current rating of −40 A at TA = 25 °C on a standard glass epoxy board (25.4 mm × 25.4 mm × 0.8 mm). Derating applies above 25 °C ambient, and actual usable current depends on PCB copper area, airflow, and thermal interface design. The UPA2732T1A-E1-AZ must not exceed its channel temperature limit of 150 °C under any operating condition.
Does UPA2732T1A-E1-AZ support logic-level gate drive?
Yes, the UPA2732T1A-E1-AZ is specified for RDS(on)2 = 6.7 mΩ maximum at VGS = −4.5 V and ID = −20 A, confirming reliable enhancement-mode operation with common 5 V or 4.5 V logic-supplied gate drivers. This makes the UPA2732T1A-E1-AZ compatible with battery protection ICs that lack dedicated high-side level-shifting outputs.
Is UPA2732T1A-E1-AZ rated for avalanche energy?
Yes, the UPA2732T1A-E1-AZ is fully characterized for unclamped inductive switching with IAS = −20 A and EAS = 40 mJ under defined test conditions (VDD = −15 V, L = 100 μH, RG = 25 Ω, Tch = 25 °C). This rating validates its use in battery disconnect circuits where inductive transients may occur during sudden load removal.
What is the thermal resistance from channel to case for UPA2732T1A-E1-AZ?
The UPA2732T1A-E1-AZ has Rth(ch-C) = 1.5 °C/W, measured from channel to the exposed drain pad. This low value assumes proper soldering of the thermal pad to a minimum 100 mm² copper area on the PCB. The UPA2732T1A-E1-AZ requires adequate thermal land design to maintain Tch ≤ 150 °C under full-load conditions.
Can UPA2732T1A-E1-AZ be used in back-to-back configuration for bidirectional blocking?
Yes, the UPA2732T1A-E1-AZ is commonly deployed in back-to-back P-channel configuration for true bidirectional blocking in battery protection circuits. Its symmetric source/drain structure (when used with matching device) and body diode forward voltage (VF(S-D) = 0.85–1.2 V) support controlled reverse current flow during charging, and the UPA2732T1A-E1-AZ maintains low RDS(on) in both directions when properly biased.
