Product details
Overview
UPA2734GR-E1-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. It integrates a gate protection diode and supports low-voltage gate drive down to −2.5 V.
For engineers reviewing the UPA2734GR-E1-AT datasheet, UPA2734GR-E1-AT pinout, UPA2734GR-E1-AT application, or UPA2734GR-E1-AT equivalent, key selection criteria include its −30 V drain-source rating, 7 A DC current capability, low input capacitance (1130 pF), built-in gate ESD protection, and suitability for synchronous buck high-side switching in compact power supplies.
Technical Context
This device operates as a logic-level-compatible P-channel switch optimized for high-efficiency, space-constrained DC/DC converters. Its gate threshold voltage range (−0.5 V to −1.5 V) enables reliable turn-on with low-voltage controllers, while its low RDS(on) at −2.5 V (72 mΩ max) supports partial-gate-drive operation in battery-powered systems.
Thermal performance is defined for mounting on a 25.4 mm × 25.4 mm × 0.8 mm glass epoxy board, with channel temperature limited to 150°C and transient thermal resistance of 114°C/W (ch-to-ambient). The integrated gate protection diode guards against ESD but requires external overvoltage clamping in high-stress applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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; lower ID(DC) = −2.7 A | Suitable only for ≤3 A loads; not recommended for 7 A DC applications | Select UPA2734GR-E1-AT when ≥7 A DC current and low RDS(on) are required in Power SOP8 footprint. |
| IRF7425PBF | RDS(on) = 42 mΩ @ −10 V; requires −10 V gate drive; SO-8 package same outline | Not logic-level compatible; needs dedicated gate driver for −4.5 V or lower control | Choose UPA2734GR-E1-AT for direct 2.5–3.3 V MCU interface without level-shifting circuitry. |
Compared with Si2301DDS-T1-GE3 and IRF7425PBF, the UPA2734GR-E1-AT uniquely delivers 7 A DC current handling with logic-level gate drive (−2.5 V) and 38 mΩ RDS(on) in Power SOP8-enabling simpler, more efficient high-current switching where gate voltage headroom is constrained.

FAQ
What is the maximum continuous drain current for UPA2734GR-E1-AT at 25°C ambient?
The UPA2734GR-E1-AT supports a DC drain current of −7 A at TA = 25°C when 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; at 70°C ambient, the practical DC limit drops to approximately −4.5 A under the same board conditions.
Does UPA2734GR-E1-AT have built-in ESD protection on the gate terminal?
Yes, the UPA2734GR-E1-AT includes an internal gate-to-source protection diode explicitly described in the datasheet as serving "as a protector against ESD." However, Renesas states that an external protection circuit remains required if voltages exceeding the ±12 V gate rating may occur in the application.
Can UPA2734GR-E1-AT be driven directly by a 3.3 V microcontroller GPIO?
Yes - the UPA2734GR-E1-AT has a gate threshold voltage range of −0.5 V to −1.5 V and guarantees RDS(on) ≤ 72 mΩ at VGS = −2.5 V, making it fully compatible with 3.3 V (and even 2.5 V) logic outputs. No level shifter is needed, though a series gate resistor (10–47 Ω) is recommended to dampen ringing.
What is the thermal resistance (Rth(ch–A)) of UPA2734GR-E1-AT under standard mounting conditions?
The transient thermal resistance from channel to ambient (Rth(ch–A)) for UPA2734GR-E1-AT is specified as 114°C/W when mounted on a 25.4 mm × 25.4 mm × 0.8 mm glass epoxy board. This value applies to single-pulse conditions and forms the basis for steady-state thermal design using the provided derating curves.
Is UPA2734GR-E1-AT RoHS compliant and lead-free?
Yes, the UPA2734GR-E1-AT is RoHS compliant and features pure tin (Sn) lead plating with no lead in external electrodes or other parts, as confirmed in the ordering information section of the official Renesas datasheet G19426EJ1V0DS00.
