Product details
Overview
AON6264E from Alpha & Omega Semiconductor is a 60V, 28A N-channel Trench Power AlphaSGT™ MOSFET in DFN5x6 package, featuring <9.5mΩ RDS(ON) at VGS=10V, 1.8V gate threshold, and 14.5nC total gate charge. It serves as a high-efficiency synchronous rectifier or primary-side switch in DC-DC converters and power supplies.
For engineers reviewing the AON6264E datasheet, pinout, applications, or equivalent options, key selection criteria include its 60V VDS, 28A continuous drain current, low 0.6–2.0Ω gate resistance, 100% UIS-tested ruggedness, and HBM Class 2 ESD protection-critical for high-frequency, high-reliability power conversion designs.
Technical Context
The AON6264E employs AlphaSGT™ trench technology to achieve low conduction loss and fast switching with 6.5ns turn-on delay and 3ns fall time. Its body diode exhibits 0.72V forward voltage at 1A and 19ns reverse recovery time, enabling efficient synchronous rectification without external Schottky diodes.
Thermally, it delivers 60W power dissipation at TC=25°C (RθJC=3.3°C/W) and supports 100% avalanche energy testing (EAS=43mJ, L=0.3mH). The device is characterized across –55°C to 150°C junction temperature range with stable RDS(ON) up to 125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon IPP60R099P7 | 650V, 99mΩ, TO-220 - higher voltage, higher RDS(ON), larger package | Designed for offline SMPS primary side; not suitable for low-voltage synchronous rectification | Select only if 650V blocking and through-hole mounting are required; not drop-in for AON6264E's 60V/DFN5x6 use case |
| Vishay SiR626DP | 60V, 8.3mΩ, PowerPAK SO-8 - similar RDS(ON) but SO-8 package, 2.5× larger footprint | Compatible with legacy SO-8 layouts; lacks HBM Class 2 ESD rating and 100% UIS test documentation | Choose when board rework for DFN5x6 is impractical; verify ESD robustness and avalanche margin in final design |
Compared with IPP60R099P7 and SiR626DP, the AON6264E offers the optimal balance of low RDS(ON), compact DFN5x6 footprint, documented UIS ruggedness, and logic-level gate drive-making it uniquely suited for high-frequency, high-density 48V/12V/5V DC-DC power stages where thermal and layout constraints dominate.

FAQ
What is the maximum continuous drain current for AON6264E at 100°C case temperature?
The AON6264E supports 28A continuous drain current at TC=25°C, derating linearly to 17A at TC=100°C per the datasheet's current de-rating curve (Figure 13). This reflects package-limited current handling under sustained thermal conditions, not silicon limitation.
Does AON6264E require a gate resistor for stability in high-speed switching?
Yes-the AON6264E has a typical gate resistance of 1.2Ω and low Qgd, making it susceptible to gate oscillation above 1MHz. A 2.2–4.7Ω series gate resistor is recommended to dampen ringing and prevent false turn-on during hard commutation in half-bridge configurations using the AON6264E.
Is AON6264E suitable for use as a synchronous rectifier in a 20V-output LLC resonant converter?
Yes-the AON6264E is explicitly validated for secondary-side synchronous rectification, with 0.72V VSD, 19ns trr, and 65nC Qrr. At 20V output, its low RDS(ON) and fast body diode recovery reduce conduction and recovery losses, enabling >96% efficiency in well-designed LLC converters using the AON6264E.
What is the thermal resistance from junction to ambient (RθJA) for AON6264E on a standard PCB?
The AON6264E has RθJA = 55°C/W when mounted on a 1in² FR-4 board with 2oz copper (per datasheet Note H). This value assumes no external heatsink; actual RθJA improves significantly with thermal vias to inner layers or copper pour-critical for sustaining 60W power dissipation in compact layouts using the AON6264E.
How is avalanche ruggedness verified for AON6264E, and what does "100% UIS Tested" mean?
"100% UIS Tested" means every AON6264E unit undergoes unclamped inductive switching stress at IAS=28A, L=0.3mH, yielding EAS=43mJ-verified per JEDEC JESD24-1. This ensures each device can survive worst-case inductive turn-off events without parameter degradation, a critical reliability requirement for the AON6264E in hard-switched topologies.
