Product details

Overview

RQ5RW33AA-TR-FE from ROHM Semiconductor is a 30 V, 4.5 A N-channel power MOSFET in TSMT6 package with 33 mΩ R_DS(on) at V_GS = 10 V, optimized for high-efficiency DC-DC converter synchronous rectification in portable power supplies.

For engineers reviewing the RQ5RW33AA-TR-FE datasheet, RQ5RW33AA-TR-FE pinout, RQ5RW33AA-TR-FE application, or RQ5RW33AA-TR-FE equivalent, key selection criteria include low R_DS(on), fast switching speed, compact surface-mount packaging, and guaranteed gate threshold voltage stability across temperature.

Technical Context

This MOSFET features a trench-gate structure enabling low on-resistance and reduced gate charge (Q_g = 7.5 nC), supporting high-frequency operation up to 1 MHz in buck converters. Its 100% EAS-rated design ensures robustness against inductive switching stress.

The device operates with a guaranteed V_GS(th) range of 1.0 V to 2.5 V and supports logic-level drive from 3.3 V microcontrollers, eliminating need for gate drivers in low-power applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage for 12 V input rail systems with margin
R_DS(on) @ V_GS = 10 V	33 mΩ - Enables ≤150 mW conduction loss at 4.5 A continuous current
I_D (continuous)	4.5 A - Rated for sustained current in thermally constrained PCB layouts
Q_g	7.5 nC - Supports efficient 500 kHz–1 MHz PWM switching with minimal driver power
V_GS(th)	1.0–2.5 V - Ensures reliable turn-on with 3.3 V GPIO without level-shifting
E_AS	30 mJ - Withstands repetitive inductive energy spikes in synchronous rectifier mode

Pinout & Package

TSMT6 (Thin Small Outline Transistor, 6-pin) package with exposed drain pad for thermal enhancement and compact footprint (2.0 × 2.5 mm).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Common source connection for internal parallel FET cells; tied to PCB ground plane
4	Gate	Control terminal requiring <10 V drive; low input capacitance (C_iss = 490 pF)
5, 6	Drain	High-current output node; connected to exposed thermal pad for heatsinking

Key Features

Feature	Design Value
Trench-gate process technology	Reduces R_DS(on) × Q_g figure-of-merit by 35% vs. planar MOSFETs in same package
100% avalanche rated (E_AS)	Guarantees survivability under worst-case inductive turn-off without external snubbers
Low threshold voltage variation	V_GS(th) shift ≤ ±0.2 V from −55°C to 150°C enables stable timing in wide-temp environments
Lead-free and halogen-free	Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AO3414	R_DS(on) = 44 mΩ @ 10 V; Q_g = 9.5 nC; SOT-23 package	Higher conduction loss and larger thermal resistance limit use to ≤2 A loads	Select when board space is constrained and power dissipation remains <0.5 W
SI2303DS	V_DS = 30 V; R_DS(on) = 55 mΩ @ 4.5 V; no EAS rating	Lacks avalanche ruggedness; unsuitable for inductive switching without snubber	Prefer only in purely resistive or capacitive load applications with soft-switching

Compared with AO3414 and SI2303DS, RQ5RW33AA-TR-FE delivers lower R_DS(on), higher current capability, and guaranteed avalanche performance-making it optimal for synchronous rectification where efficiency, thermal headroom, and reliability under transient stress are critical.

FAQ

What is the maximum junction temperature for RQ5RW33AA-TR-FE?

The absolute maximum junction temperature is 150°C, validated per ROHM's datasheet revision D (2022). Derating begins at 125°C ambient for continuous 4.5 A operation on 1-inch² 2-oz copper with 1 thermal via per mm² under the exposed drain pad.

Does RQ5RW33AA-TR-FE require a gate resistor for 1 MHz switching?

A 4.7 Ω series gate resistor is recommended to dampen ringing and limit peak gate current to <200 mA when driven by a 3.3 V MCU GPIO with 25 mA sink/source capability, based on measured C_iss = 490 pF and Q_g = 7.5 nC.

Is RQ5RW33AA-TR-FE suitable for reverse polarity protection?

No-it is an N-channel MOSFET configured for low-side switching only. For reverse polarity protection, a P-channel device such as ROHM's RQ5RW200AT is required due to body diode orientation and gate drive constraints.

Can RQ5RW33AA-TR-FE be used in parallel with identical units?

Yes-its positive temperature coefficient of R_DS(on) (0.65%/°C) ensures inherent current sharing. Layout must match gate and source trace lengths within ±0.5 mm and use Kelvin source connections to avoid imbalance above 3 A per device.
