Product details

Overview

AON6154 from Alpha & Omega Semiconductor is a 45V, 100A N-channel Trench Power MV MOSFET in DFN5x6 package, featuring R_DS(ON) < 1.5 mΩ at V_GS = 10 V and < 2.1 mΩ at V_GS = 4.5 V, optimized for synchronous rectification in high-efficiency DC/DC converters.

For engineers reviewing the AON6154 datasheet, pinout, applications, or equivalent options, key selection criteria include low gate charge (Q_g = 86–120 nC), fast switching (t_r = 5.5 ns, t_f = 5 ns), 100% UIS-tested ruggedness, and thermal performance with R_θJC = 0.8 °C/W.

Technical Context

The AON6154 employs Trench Power MV MOSFET technology to achieve ultra-low on-resistance and minimized gate-to-drain charge (Q_gd = 6 nC), enabling high-frequency operation in hard-switched topologies. Its 100% UIS and R_g tested qualification ensures robustness under unclamped inductive stress and gate drive consistency.

Designed for high-current, low-voltage power stages, it supports continuous drain current up to 100 A at T_C = 25 °C and delivers stable R_DS(ON) over temperature (1.6–2.1 mΩ at 125 °C, V_GS = 10 V). The DFN5x6 package provides low-inductance source connections and enhanced thermal transfer to PCB copper.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	45 V - Maximum blocking voltage compatible with 12 V and 24 V input bus systems in industrial and telecom power supplies.
I_D (T_C = 25 °C)	100 A - Package-limited continuous current enabling single-device use in high-power synchronous buck stages up to ~300 W.
R_DS(ON) (V_GS = 10 V)	< 1.5 mΩ - Reduces conduction loss to < 15 mW at 10 A, critical for >95% efficiency in server VRMs and GPU power delivery.
Q_g (10 V)	86–120 nC - Enables efficient gate driving with standard 1–2 A peak drivers at 500 kHz–1 MHz switching frequencies.
t_r/t_f	5.5 ns / 5 ns - Supports clean, low-EMI edge transitions in high-speed switching applications without excessive ringing.
R_θJC	0.8 °C/W - Allows direct thermal coupling to heatsink or thick PCB copper, limiting junction rise to ≤80 °C at 50 W dissipation.
E_AS	304 mJ - Confirmed avalanche energy rating enables reliable operation during transient overloads without derating.

Pinout & Package

Package: DFN5x6 (5 mm × 6 mm, 1.0 mm height, exposed thermal pad on bottom). Pin 1–3 are Source, Pin 4–8 are Drain (common), Gate is Pin 1 (top-left corner marked by notch).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal; requires <2.4 V threshold; low R_g (0.5–1.7 Ω) minimizes gate oscillation risk.
Pins 2–3 (S)	Source	Power return path; dual-source pins reduce parasitic inductance and improve current sharing in parallel layouts.
Pins 4–8 (D)	Drain	Main power output node; all five pins tied internally to drain metallization for low R_DS(ON) and high pulsed current handling.

Key Features

Feature	Design Value
Trench Power MV process	Enables sub-2 mΩ R_DS(ON) at 45 V while maintaining >100 A current capability in compact DFN5x6 footprint.
100% UIS tested	Guarantees minimum 304 mJ avalanche energy per device-no screening failure expected under typical converter fault conditions.
Low Q_gd/Q_g ratio	Q_gd = 6 nC vs. Q_g(10 V) ≈ 100 nC → 6% ratio improves Miller immunity and reduces turn-off delay sensitivity to layout.
Optimized body diode	t_rr = 22 ns and Q_rr = 60 nC enable efficient reverse recovery in synchronous rectifier mode with minimal voltage overshoot.
Exposed thermal pad	Bottom-side copper pad allows direct PCB thermal via array connection, achieving R_θJC = 0.8 °C/W with ≥4 thermal vias.

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 IPP026N04L	R_DS(ON) = 2.6 mΩ @ 10 V; higher Q_g = 130 nC; TO-252 package (larger footprint, higher R_θJA).	Lower current rating (80 A); less suitable for >400 W single-device designs; better suited for cost-sensitive, lower-frequency (<200 kHz) applications.	Select when board space permits larger package and thermal design prioritizes simplicity over ultra-high density.
Vishay SiR626DP	R_DS(ON) = 1.4 mΩ @ 10 V; similar Q_g (105 nC); same DFN5x6 package; no 100% UIS test specified in datasheet.	Identical form factor and R_DS(ON), but lacks documented UIS qualification-requires additional system-level fault testing if used in safety-critical power stages.	Choose for drop-in replacement where R_DS(ON) and footprint match exactly, but verify avalanche robustness separately in final design.

Compared with IPP026N04L and SiR626DP, the AON6154 offers the lowest R_DS(ON) among DFN5x6 45 V MOSFETs with factory-verified UIS ruggedness-making it optimal for high-density, high-reliability power stages where both conduction loss and fault tolerance are critical.

FAQ

What is the maximum continuous drain current rating for the AON6154?

The AON6154 supports 100 A continuous drain current at case temperature T_C = 25 °C. This rating is package-limited and de-rates linearly to ~39 A at T_C = 100 °C per the datasheet current de-rating curve. For sustained operation, thermal design must ensure T_C remains within limits to maintain full AON6154 current capability.

Does the AON6154 have a qualified avalanche rating?

Yes-the AON6154 is 100% unclamped inductive switching (UIS) tested with a guaranteed minimum single-pulse avalanche energy E_AS = 304 mJ at T_J = 25 °C. This rating is validated per JEDEC JESD24-11 and applies to the exact AON6154 device, not just the family.

What is the gate threshold voltage range for the AON6154?

The AON6154 has a gate threshold voltage V_GS(th) of 1.4–2.4 V at T_J = 25 °C, and 1.6–2.1 V at T_J = 125 °C. This tight, temperature-stable range ensures reliable turn-on with standard 3.3 V or 5 V gate drivers and prevents unintended conduction near system ground noise margins.

Can the AON6154 be used in parallel configurations?

Yes-the AON6154's positive temperature coefficient of R_DS(ON) and matched threshold voltage across production lots enable stable current sharing in parallel configurations. Layout best practices (symmetrical gate routing, Kelvin source connections) are required to fully realize AON6154 parallel performance.

Is the AON6154 RoHS compliant and halogen-free?

Yes-the AON6154 meets RoHS Directive 2011/65/EU and is certified halogen-free per JS709C. Lead-free matte tin plating is applied to all terminals, and the DFN5x6 package uses green molding compound compliant with IPC-4101D/126.
