Product details

Overview

UPA2735GR-E1-AX from Renesas Electronics is a P-channel enhancement-mode MOSFET designed for high-efficiency DC/DC converter and power management circuits in portable electronics. It delivers −30 V drain-source voltage rating, −16 A continuous drain current, 5.0 mΩ maximum R_DS(on) at V_GS = −10 V, and supports 4.5 V gate drive for compatibility with low-voltage controllers.

For engineers reviewing the UPA2735GR-E1-AX datasheet, UPA2735GR-E1-AX pinout, UPA2735GR-E1-AX application, or UPA2735GR-E1-AX equivalent, key selection criteria include its SOP-8 package thermal performance (R_th(ch-A) = 114 °C/W), avalanche energy rating (E_AS = 25.6 mJ), and dual gate-drive capability (−4.5 V and −10 V R_DS(on) specs).

Technical Context

This MOSFET operates as a synchronous rectifier or high-side switch in buck converters and battery protection circuits. Its −2.5 V typical gate threshold (V_GS(off)) enables reliable turn-off under low-voltage bias, while its 195 nC total gate charge and 100 nC Q_GD support controlled switching transitions in high-frequency power stages.

The device integrates a body diode with 0.82 V forward voltage at 16 A and 60 ns reverse recovery time, enabling efficient freewheeling operation. Its transient thermal resistance curve confirms suitability for pulsed loads up to −150 A with 100 μs pulse width on standard 25.4 mm × 25.4 mm PCB mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V - Withstands full system rail voltage in 3.3 V–12 V portable DC/DC applications without breakdown.
R_DS(on) @ V_GS = −10 V	5.0 mΩ max - Enables <1 W conduction loss at −16 A DC, critical for thermal management in compact layouts.
R_DS(on) @ V_GS = −4.5 V	7.8 mΩ max - Ensures functional switching with 4.5 V logic-level gate drivers, eliminating need for level shifters.
Q_G	195 nC - Determines gate driver current requirement; ~20 mA average needed for 1 MHz switching with 10 ns rise time.
E_AS	25.6 mJ - Supports single-pulse inductive load switching without failure, essential for overcurrent fault tolerance.
C_iss	6250 pF - Impacts gate drive power loss and loop stability; requires careful compensation in high-frequency control loops.
T_ch max	150 °C - Sets maximum junction temperature limit; derating required above 25 °C ambient per published curves.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2301DS-T1-E3	R_DS(on) = 115 mΩ @ −4.5 V; lower current rating (−3.1 A); SOT-23 package.	Targeted at ultra-low-power always-on loads, not high-current DC/DC stages.	Select only for sub-1 A applications where board space is critical and thermal budget permits higher R_DS(on).
IRF7425PBF	R_DS(on) = 28 mΩ @ −10 V; SO-8 package; no 4.5 V drive spec; higher Q_G (54 nC).	Designed for medium-frequency motor drives, not high-efficiency portable power conversion.	Prefer when gate drive voltage exceeds 8 V and switching frequency is below 500 kHz; avoid for 4.5 V logic interfaces.

Compared with Si2301DS-T1-E3 and IRF7425PBF, the UPA2735GR-E1-AX uniquely balances low R_DS(on), 4.5 V gate compatibility, and robust avalanche capability-making it optimal for thermally constrained, high-current portable DC/DC designs where both efficiency and fault resilience are mandatory.

FAQ

What is the maximum continuous drain current for UPA2735GR-E1-AX at 25°C ambient?

The UPA2735GR-E1-AX supports −16 A continuous drain current (I_D(DC)) at T_A = 25°C when mounted on a 25.4 mm × 25.4 mm glass epoxy board. Derating applies above 25°C per the published derating curve; at 75°C ambient, the usable DC current drops to approximately −8 A due to thermal limits.

Does UPA2735GR-E1-AX support 4.5 V gate drive, and what is its R_DS(on) at that voltage?

Yes, UPA2735GR-E1-AX is explicitly rated for 4.5 V gate drive. At V_GS = −4.5 V and I_D = −16 A, its R_DS(on) is 7.8 mΩ maximum-enabling full enhancement without external level shifting in 4.5 V logic systems.

What is the thermal resistance from channel to ambient for UPA2735GR-E1-AX?

The channel-to-ambient thermal resistance (R_th(ch-A)) of UPA2735GR-E1-AX is 114 °C/W when mounted on a standard 25.4 mm × 25.4 mm × 0.8 mm glass epoxy PCB. This value assumes natural convection and defines the baseline for junction temperature calculation under steady-state power dissipation.

Is UPA2735GR-E1-AX suitable for avalanche operation, and what are its rated parameters?

Yes, UPA2735GR-E1-AX is avalanche-rated: single-pulse I_AS = 16 A and E_AS = 25.6 mJ, tested under defined conditions (V_DD = −15 V, L = 100 μH, R_G = 25 Ω). This rating supports safe inductive switching in DC/DC converters without external snubbers.

What package type and lead finish does UPA2735GR-E1-AX use?

UPA2735GR-E1-AX uses the SOP-8 surface-mount package (JEITA code P-SOP8-3.95×4.9-1.27) with Ni/Pd/Au lead plating. This finish ensures solderability, corrosion resistance, and compliance with Pb-free assembly requirements per RoHS Directive.
