Product details

Overview

ZXMN6A09GQTA from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in SOT223 package, qualified to AEC-Q101 for automotive use. It delivers R_DS(ON) = 0.04 Ω @ V_GS = 10V, 7.5A continuous drain current at T_A = +25°C, and supports 100% unclamped inductive switching (UIS). It is deployed in DC-DC converters, power management functions, and motor control circuits.

For engineers reviewing the ZXMN6A09GQTA datasheet, ZXMN6A09GQTA pinout, ZXMN6A09GQTA application, or ZXMN6A09GQTA equivalent, key selection criteria include its AEC-Q101 qualification, low 0.04Ω on-resistance at 10V gate drive, 60V V_DSS, fast 4.9ns turn-on delay, and SOT223 thermal performance with R_θJA = 32.2°C/W under FR-4 PCB conditions.

Technical Context

This MOSFET employs planar trench-gate silicon technology optimized for high-voltage automotive switching. Its gate threshold voltage (1–3V) enables compatibility with 3.3V and 5V logic-level drivers, while its low Q_g (24.2 nC @ 10V) and fast t_F (4.6 ns) support high-frequency PWM operation in DC-DC stages.

The device integrates a robust body diode with t_RR = 26.3 ns and Q_RR = 26.6 nC, enabling efficient synchronous rectification and flyback recovery in buck and half-bridge topologies. Its 1.17A avalanche current rating and 0.07 mJ E_AS ensure ruggedness against transient energy in inductive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Withstands up to 60V drain-source blocking voltage, suitable for 48V automotive bus and industrial 24–48V systems.
R_DS(ON) @ 10V	0.04 Ω - Enables <1.2W conduction loss at 7.5A, critical for thermally constrained SOT223 layouts.
I_D (continuous)	7.5 A @ T_A = +25°C - Supports medium-power switching in compact surface-mount applications without heatsinking.
Q_g @ 10V	24.2 nC - Low gate charge reduces driver power demand and improves efficiency in 100–500 kHz SMPS designs.
t_D(ON)	4.9 ns - Enables precise timing control in high-speed synchronous rectifiers and motor gate drivers.
E_AS	0.07 mJ - Confirmed single-pulse avalanche energy handling for reliable operation during load dump or inductive kick events.

Pinout & Package

SOT223 package: surface-mount, 4-pin (3 active + tab), molded green compound, UL 94V-0 rated, 0.112 g weight, moisture sensitivity level 1. Tab is Drain-connected for enhanced thermal transfer to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output	Internally connected to exposed metal tab; must be soldered to large copper pour for thermal dissipation and electrical connection.
Source	Current return path / reference node	Common node for gate drive reference and load return; ties directly to ground plane in high-side switch configurations.
Gate	Control input	High-impedance terminal requiring <24.2 nC charge for full enhancement; sensitive to ESD and layout-induced ringing.
Drain (Pin 1)	Redundant drain connection	Secondary drain pin for mechanical stability and current sharing; electrically identical to tab but not intended as primary thermal path.

Key Features

Feature	Design Value
AEC-Q101 qualified & PPAP capable	Validated for automotive production with full change control, IATF16949 manufacturing, and traceable lot documentation.
100% UIS tested in production	Each unit passes unclamped inductive switching stress test, ensuring reliability in motor and solenoid drive applications.
Low V_GS(TH) (1–3V)	Enables direct drive from microcontroller GPIOs or low-voltage logic without level-shifting circuitry.
Halogen- and antimony-free "Green" construction	Meets automotive environmental standards with Br+Cl <1500 ppm and Sb <1000 ppm; RoHS 3 compliant.
Fast reverse recovery (t_RR = 26.3 ns)	Minimizes switching losses and cross-conduction risk in synchronous rectifier and half-bridge configurations.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 60V automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN601DWKQ-13	R_DS(ON) = 0.045 Ω @ 10V; SOT23-3 package; lower I_D = 4.8A; no UIS testing	Limited to <3A continuous loads; unsuitable for motor or high-energy inductive switching	Select only for space-constrained, low-current logic-level switching where AEC-Q101 is not required.
IPD60R190P7SAKMA1	600V superjunction MOSFET; TO-252; R_DS(ON) = 0.19 Ω; higher V_GS(TH) = 2.5–4.5V	Designed for 400V+ PFC and offline SMPS; incompatible with 12V/48V automotive gate drivers	Not interchangeable-intended for high-voltage AC/DC, not low-voltage DC-DC or motor control.

Compared with DMN601DWKQ-13 and IPD60R190P7SAKMA1, ZXMN6A09GQTA uniquely combines AEC-Q101 qualification, 7.5A current capability in SOT223, and production-tested UIS robustness-making it the only viable option for thermally demanding, safety-critical 48V automotive power switches.

FAQ

Is ZXMN6A09GQTA suitable for 48V mild-hybrid vehicle systems?

Yes. Its 60V V_DSS, AEC-Q101 qualification, and 100% UIS testing make it appropriate for 48V bus switching, including start-stop and regenerative braking subsystems. It withstands ISO 7637-2 pulse 5a (load dump) up to +65V when properly clamped and heatsinked.

What is the maximum recommended PCB copper area for thermal performance in SOT223?

For optimal R_θJA = 32.2°C/W, Diodes specifies a 25mm × 25mm single-sided 1oz copper pad connected to the drain tab. Adding internal thermal vias (≥8×0.3mm diameter, filled or capped) to inner ground planes further reduces junction-to-ambient resistance by ~15%.

Does ZXMN6A09GQTA require a gate resistor for EMI suppression in PWM applications?

Yes. A 10–22Ω series gate resistor is recommended to dampen ringing caused by parasitic L_g/C_iss resonance. This controls dV/dt during switching, reduces radiated emissions, and prevents false triggering-especially critical in 200–500 kHz DC-DC converters near sensitive RF receivers.

Can ZXMN6A09GQTA replace older ZXMN6A07GQTA in existing designs?

Yes, with verification. Both share identical SOT223 package, pinout, and AEC-Q101 qualification, but ZXMN6A09GQTA offers lower R_DS(ON) (0.04Ω vs. 0.05Ω @ 10V) and improved UIS ruggedness. Layout and thermal validation are advised due to higher current capability and slightly increased Q_g.
