Product details

Overview

AON6362 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 DC-DC power conversion in server VRMs and POL converters.

For engineers reviewing the AON6362 datasheet, pinout, applications, or equivalent options, key selection criteria include R_DS(on) at 10 V and 4.5 V gate drive, Q_g and Q_gd for switching loss estimation, thermal resistance (R_θJA), and compliance with halogen-free packaging requirements per AOS Green Policy.

Technical Context

The AON6362 uses trench-gate MOSFET technology to achieve low on-resistance and fast switching characteristics. It supports standard logic-level gate drive (V_GS(th) = 1.8 V typ) and operates reliably across -55 °C to +150 °C junction temperature range.

Its DFN5x6 package features an exposed drain pad for enhanced thermal performance and is qualified to JEDEC JESD47 reliability standards. The device is rated for repetitive avalanche energy (E_AS) of 120 mJ at T_J = 25 °C.

Key Specifications

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 17 A continuous current
R_DS(on) @ V_GS = 4.5 V	5.2 mΩ - ensures robust operation with 5 V gate drive in synchronous buck stages
Q_g	19 nC - determines total gate charge driving requirement for PWM controller
Q_gd	5.5 nC - directly impacts Miller-induced switching delay and shoot-through risk
R_θJA	50 °C/W - measured on 1-in² 2-oz copper PCB; defines thermal derating above 25 °C ambient

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
IRF6642	R_DS(on) = 4.2 mΩ @ 10 V; Q_g = 22 nC; TO-252 package	Larger footprint and higher R_θJA (62 °C/W); less suitable for ultra-thin POL modules	Prefer AON6362 where board space and thermal resistance are constrained
SiR872DP	R_DS(on) = 3.8 mΩ @ 10 V; Q_gd = 6.1 nC; same DFN5x6 package	Slightly higher Miller charge increases switching loss at >1 MHz; not halogen-free certified	Choose AON6362 when halogen-free compliance and lower Q_gd are mandatory

Compared with IRF6642 and SiR872DP, the AON6362 delivers superior thermal performance in space-constrained layouts, lower Miller-induced switching delay, and guaranteed halogen-free construction - critical for automotive and telecom OEMs with strict material declarations.

FAQ

What is the maximum continuous drain current rating for the AON6362?

The AON6362 is rated for 42 A continuous drain current at T_C = 25 °C with proper heatsinking. Derating applies above 25 °C case temperature per its R_θJC = 1.2 °C/W specification. At 100 °C case temperature, the usable continuous current drops to approximately 25 A.

Does the AON6362 require a gate driver IC in typical buck converter applications?

The AON6362 can be driven directly by many PWM controllers with ≥±1 A peak gate drive capability due to its 19 nC total gate charge. For high-frequency (>1 MHz) or high-current (>60 A) designs, a dedicated gate driver improves switching speed and reduces losses, but it is not mandatory for standard 500 kHz–1 MHz POL use cases.

Is the AON6362 halogen-free and RoHS compliant?

Yes, the AON6362 is fully halogen-free (Br/Cl <900 ppm each, total halogens <1500 ppm) and RoHS compliant per AOS Green Policy. It was converted to green status by 2010 and carries no "L" suffix because the DFN5x6 package is exclusively manufactured in halogen-free form.

What is the avalanche energy rating of the AON6362?

The AON6362 is rated for 120 mJ of single-pulse avalanche energy (E_AS) at T_J = 25 °C. This rating supports robustness during inductive load switching and transient overvoltage events in well-designed power stages with appropriate snubbing and layout practices.

Can the AON6362 be used in parallel configurations?

Yes, the AON6362 supports paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing. Successful implementation requires matched gate drive paths, symmetrical PCB layout, and individual source resistors for dynamic balancing - verified in AOS application note AN-1001 for multi-FET POL designs.
