Product details

Overview

AON6292 from Alpha & Omega Semiconductor is a 30 V, 42 A, 3.5 mΩ N-channel MOSFET in a 5 mm × 6 mm DFN package with exposed drain pad, optimized for high-efficiency synchronous buck converters and load switches in DC-DC power supplies.

For engineers reviewing the AON6292 datasheet, pinout, applications, or equivalent options, key selection criteria include R_DS(on) at 10 V and 4.5 V gate drive, Q_g of 17 nC, thermal resistance (R_θJA = 40 °C/W), and RoHS-compliant halogen-free construction.

Technical Context

The AON6292 employs trench-gate MOSFET technology to achieve low on-resistance and fast switching performance. It supports logic-level gate drive (V_GS(th) = 1.8 V typical) and features a 100 % UIS-rated ruggedness test per JEDEC JESD24-11.

Designed for high-frequency operation up to 1 MHz, the device delivers low conduction and switching losses in compact 5×6 DFN packages. Its thermally enhanced layout places the drain on the bottom-side exposed pad for direct PCB thermal coupling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - maximum drain-source voltage for 12 V input rail applications with margin
R_DS(on) @ V_GS = 10 V	3.5 mΩ - enables <1 W conduction loss at 15 A continuous current
R_DS(on) @ V_GS = 4.5 V	5.2 mΩ - ensures full enhancement with 3.3 V or 5 V gate drivers
Q_g	17 nC - reduces gate drive power and enables efficient 500 kHz–1 MHz switching
R_θJA	40 °C/W - requires ≥250 mm² 2-oz copper thermal pad for ≤85 °C junction rise at 3 W dissipation
Package	5×6 mm DFN-8 - surface-mount, thermally enhanced, halogen-free molding compound

Pinout & Package

Package: 5 mm × 6 mm DFN-8 with exposed drain pad (pin 1–7 signal, pin 8 drain tie-bar). Thermal pad must be soldered to PCB ground plane for rated performance.

Pin/Terminal	Circuit Role	Design Meaning
1–3, 5–7	Source	Common source connection; tied internally to thermal pad via substrate
4	Gate	Control terminal; accepts 3.3 V/5 V logic-level drive without level-shifting
8 + underside pad	Drain	Main power path output; requires full-solder coverage to PCB for thermal integrity

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
Infineon BSC028N06NS3	R_DS(on) = 2.8 mΩ @ 10 V, Q_g = 22 nC, same 5×6 DFN package	Higher gate charge increases driver loss at >1 MHz; better for lower-frequency, ultra-low-R_DS(on) priority designs	Prefer when R_DS(on) reduction outweighs gate drive complexity
Vishay SiR626DP	R_DS(on) = 4.0 mΩ @ 10 V, Q_g = 14.5 nC, 5×6 PowerPAK® SO-8 compatible footprint	Higher R_DS(on) but lower Q_g; requires different PCB layout due to SO-8 pinout	Choose if legacy SO-8 layout reuse is required and 0.5 mΩ R_DS(on) penalty is acceptable

Compared with BSC028N06NS3 and SiR626DP, the AON6292 offers balanced trade-off between conduction loss (3.5 mΩ), gate drive efficiency (17 nC), and thermal performance (40 °C/W), making it optimal for space-constrained 500 kHz–1 MHz DC-DC converters where both efficiency and layout simplicity matter.

FAQ

What is the maximum continuous drain current rating for AON6292 at 25 °C ambient?

The AON6292 is rated for 42 A continuous drain current (I_D) at T_A = 25 °C with proper PCB thermal management. This assumes use of a 2-oz copper thermal pad ≥250 mm². At 100 °C ambient, derated current drops to 22 A per the datasheet's thermal curves. The AON6292's 3.5 mΩ R_DS(on) directly determines this current capability under thermal constraints.

Does AON6292 support 3.3 V gate drive in practice?

Yes, the AON6292 supports 3.3 V gate drive due to its logic-level V_GS(th) of 1.8 V (typical) and R_DS(on) of 5.2 mΩ at V_GS = 4.5 V. At 3.3 V, R_DS(on) rises to ~7.8 mΩ, which remains usable in low-duty-cycle or low-current applications. For full 42 A capability, 4.5 V or higher is recommended. The AON6292's gate threshold ensures reliable turn-on with standard 3.3 V microcontrollers.

Is AON6292 halogen-free and RoHS compliant?

Yes, the AON6292 is manufactured using halogen-free molding compound meeting IEC 61249-2-21:2017, with bromine and chlorine each <900 ppm and total Br+Cl <1500 ppm. It is fully RoHS compliant and carries no "L" suffix because all AON6292 units shipped post-2010 are green-version parts. No non-halogen-free variant exists for this DFN package.

What is the thermal resistance R_θJA of AON6292, and how is it measured?

The AON6292 has a junction-to-ambient thermal resistance (R_θJA) of 40 °C/W when mounted on a standard JEDEC 2S2P test board (1 in² 2-oz copper). This value assumes full-solder coverage of the exposed drain pad to an internal ground plane. R_θJA improves significantly with larger copper areas-e.g., 250 mm² 2-oz pad reduces it to ~28 °C/W. The AON6292's thermal performance is validated per JESD51-2.

Can AON6292 replace AON6280 in an existing design?

The AON6292 is not a direct replacement for AON6280: while both are 30 V DFN MOSFETs, the AON6280 has R_DS(on) = 4.0 mΩ @ 10 V and Q_g = 14 nC, whereas the AON6292 offers lower R_DS(on) (3.5 mΩ) but higher Q_g (17 nC). Layout compatibility is maintained, but gate drive strength and thermal margin should be re-evaluated. The AON6292 provides measurable efficiency gain in conduction-limited designs.
