Product details
Overview
UPA2734GR-E2-AT from Renesas Electronics is a P-channel power MOSFET designed for DC/DC converter and power management applications, featuring RDS(on) = 38 mΩ max at VGS = −4.5 V and ID = −7.0 A, VDSS = −30 V, and Power SOP8 surface-mount package.
For engineers reviewing the UPA2734GR-E2-AT datasheet, UPA2734GR-E2-AT pinout, UPA2734GR-E2-AT application, or UPA2734GR-E2-AT equivalent, key selection criteria include low on-resistance at logic-level gate drive (−2.5 V), built-in gate protection diode, and thermal performance on standard glass-epoxy PCBs.
Technical Context
This device operates as a high-side switch in synchronous buck converters and load-switching circuits, leveraging its −30 V VDSS rating and −7 A continuous drain current capability. Its gate threshold voltage range (VGS(off) = −0.5 to −1.5 V) ensures reliable turn-on with standard logic-level controllers.
The integrated gate protection diode guards against ESD, while its Ciss = 1130 pF (typ.) and QG = 12 nC support fast switching with moderate gate drive strength. The body diode exhibits VF(S-D) = 0.93–1.2 V at 7 A, enabling use in freewheeling paths without external diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −30 V - supports input rails up to 24 V DC/DC stages with margin |
| RDS(on)1 | 38 mΩ max @ VGS = −4.5 V, ID = −7 A - enables <1 W conduction loss at full load |
| RDS(on)2 | 72 mΩ max @ VGS = −2.5 V, ID = −3.5 A - compatible with 2.5 V logic or battery-backed control |
| Ciss | 1130 pF typ. @ VDS = −10 V - determines gate drive power and switching speed trade-off |
| QG | 12 nC - sets minimum gate driver current requirement for <100 ns switching |
| Tch max | 150 °C - defines maximum junction temperature under derated power dissipation |
| VF(S-D) | 0.93–1.2 V @ IF = 7 A - allows body-diode conduction during dead-time without external diode |
Pinout & Package
UPA2734GR-E2-AT uses the Power SOP8 package (6.0 mm × 4.4 mm × 1.8 mm height), optimized for thermal dissipation on standard FR-4 or glass-epoxy PCBs. Mounting requires solder reflow per J-STD-020 profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Main current return path; electrically tied to exposed thermal pad (not isolated) |
| 4 | Gate | Control terminal; requires external gate resistor to limit dV/dt and ringing |
| 5, 6, 7, 8 | Drain | High-side switching node; connected to input rail and inductor connection point |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Guaranteed turn-on at VGS = −2.5 V supports direct interface with 2.5 V/3.3 V microcontrollers |
| Built-in gate protection diode | ESD protection up to ±2 kV HBM reduces need for external TVS on gate line |
| Low output charge (QGD) | 5.9 nC minimizes Miller-induced shoot-through risk in half-bridge configurations |
| RoHS-compliant pure Sn plating | Enables lead-free reflow assembly without whisker risk or intermetallic concerns |
Applications
| DC/DC Synchronous Buck Converter | Hot-Swap Load Switch |
|---|---|
Use Scenario: Step-down regulation from 12 V or 24 V bus to 3.3 V/5 V for FPGA or MCU core supplies. IC Role / Device Role / Timing Role: High-side P-channel MOSFET in synchronous rectification topology, replacing bootstrap N-channel solution.

IC Role / Device Role / Timing Role: Low-standby-current high-side switch controlled by CAN/LIN microcontroller GPIO. Use Value: Supports −40 °C to +125 °C ambient operation with derated RDS(on); meets "Standard" grade automotive 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 |
|---|---|---|---|
| Si2301DDS-T1-GE3 | VDSS = −20 V, RDS(on) = 115 mΩ @ −4.5 V - lower voltage rating, higher on-resistance | Restricted to ≤16 V input rails; unsuitable for 24 V industrial systems | Select only when board space is critical and voltage stress remains below 16 V. |
| IRLML6344TRPBF | VDSS = −20 V, RDS(on) = 42 mΩ @ −4.5 V - same package but lower voltage rating | Lacks −30 V margin needed for transient clamping in 24 V automotive environments | Preferable only for cost-sensitive consumer applications with stable ≤15 V supply. |
Compared with Si2301DDS-T1-GE3 and IRLML6344TRPBF, the UPA2734GR-E2-AT provides superior voltage margin (−30 V), lower RDS(on) at −4.5 V, and validated thermal performance on industry-standard PCBs-making it optimal for industrial DC/DC and 24 V load-switching where reliability and margin matter.

FAQ
What is the maximum continuous drain current for UPA2734GR-E2-AT at 25°C ambient?
The UPA2734GR-E2-AT supports −7 A DC drain current at TA = 25°C with VGS = −4.5 V, mounted on a 25.4 mm × 25.4 mm × 0.8 mm glass-epoxy board. Derating applies above 25°C per the datasheet's forward bias safe operating area curve.
Does UPA2734GR-E2-AT have built-in ESD protection?
Yes, the UPA2734GR-E2-AT integrates a gate-to-source protection diode explicitly described in the datasheet as an ESD safeguard. However, Renesas recommends adding external gate protection if voltage transients exceeding ±12 V may occur in the application.
Can UPA2734GR-E2-AT be driven directly by a 3.3 V microcontroller GPIO?
Yes - the UPA2734GR-E2-AT guarantees RDS(on) ≤ 72 mΩ at VGS = −2.5 V and ID = −3.5 A, making it fully compatible with 3.3 V logic outputs (with appropriate level-shifting or pull-up configuration for negative gate drive).
What is the thermal resistance from channel to ambient for UPA2734GR-E2-AT?
The datasheet specifies Rth(ch-A) = 114 °C/W when mounted on a 25.4 mm × 25.4 mm × 0.8 mm glass-epoxy board. This value is used to calculate junction temperature rise under steady-state power dissipation conditions for the UPA2734GR-E2-AT.
Is UPA2734GR-E2-AT RoHS compliant and lead-free?
Yes, the UPA2734GR-E2-AT features pure Sn lead plating and is explicitly marked Pb-free in the ordering information. It complies with EU RoHS Directive requirements and contains no lead in external electrodes or other parts.
