Product details
Overview
AONS62920 from Alpha & Omega Semiconductor is a 100V, logic-level N-channel Trench Power AlphaSGT™ MOSFET in DFN5x6 package, with RDS(ON) < 6.3 mΩ at VGS = 10 V and < 7.6 mΩ at VGS = 4.5 V, rated for 48 A continuous drain current, and optimized for synchronous rectification in high-efficiency AC/DC adapters and USB PD 3.0 quick chargers.
For engineers reviewing the AONS62920 datasheet, pinout, applications, or equivalent options, key selection criteria include its low gate threshold (1.3–2.3 V), 100% UIS-tested ruggedness, 0.5–1.8 Ω gate resistance, 65–95 nC total gate charge at 10 V, and thermal performance validated up to 150°C junction temperature.
Technical Context
The AONS62920 employs AlphaSGT™ trench-gate superjunction technology to achieve high cell density and low conduction loss while maintaining fast switching. Its logic-level drive capability enables direct interfacing with 3.3 V and 5 V controllers without level-shifting circuitry.
It features a fully characterized body diode with 0.68–1.0 V forward voltage at 1 A, 32 ns reverse recovery time, and 162 nC reverse recovery charge under 20 A/500 A/μs conditions - critical for ZVS and SR control in resonant topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, logic-level 100V MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon IPP040N10N5 | RDS(ON) = 4.0 mΩ @ 10 V, but VGS(th) = 2.2–3.3 V - less tolerant of low-voltage gate drive. | Requires 5 V gate bias for full enhancement; not suitable for 3.3 V SR controllers. | Select when maximum efficiency at 10 V drive is prioritized and gate voltage margin is available. |
| Vishay SiR626DP | RDS(ON) = 6.7 mΩ @ 10 V, Qg = 102 nC - higher switching loss and slower turn-off (td(off) = 65 ns). | Higher Eoss increases hard-switching loss in QR flyback above 150 kHz. | Select when cost sensitivity outweighs switching performance and thermal constraints are relaxed. |
Compared with IPP040N10N5 and SiR626DP, the AONS62920 delivers superior logic-level compatibility, lower gate charge, and tighter Rg tolerance - making it optimal for space-constrained, high-frequency synchronous rectifiers where gate drive voltage headroom is limited.

FAQ
What is the maximum continuous drain current rating for AONS62920 at 100°C case temperature?
The AONS62920 supports 48 A continuous drain current at TC = 100°C, as specified in the Absolute Maximum Ratings table. This rating is package-limited and assumes proper PCB thermal design with ≥1 in² 2 oz. copper connected to the exposed thermal pad. At higher ambient temperatures, current must be derated per Figure 13 in the datasheet.
Does AONS62920 require a gate resistor, and what value is recommended?
Yes, the AONS62920 requires an external gate resistor to control switching speed and suppress ringing. The datasheet specifies Rg = 0.5–1.8 Ω (100% tested), and a 1.0 Ω non-inductive resistor is recommended for most 100–300 kHz applications to balance EMI and switching loss while ensuring td(off) = 51 ns and tf = 9 ns performance.
Is AONS62920 suitable for use in synchronous rectification with 3.3 V gate drive?
Yes, the AONS62920 is explicitly designed for logic-level drive: its gate threshold voltage is 1.3–2.3 V, and RDS(ON) remains < 7.6 mΩ at VGS = 4.5 V. It achieves full enhancement with 3.3 V gate drive in typical PCB layouts, enabling direct interface with USB PD 3.0 policy engines and low-voltage SR controllers without level shifters.
What is the avalanche energy rating of AONS62920, and how is it tested?
The AONS62920 is 100% unclamped inductive switching (UIS) tested with EAS = 97 mJ at L = 0.1 mH and TJ ≤ 150°C. Testing follows JEDEC standard JESD24-1 using the circuit in Figure C (Page 6), verifying single-pulse avalanche ruggedness essential for QR flyback and LLC converters during overload or startup conditions.
How does the thermal performance of AONS62920 compare between junction-to-case and junction-to-ambient metrics?
The AONS62920 has RθJC = 1.1 °C/W (steady-state) and RθJA = 50 °C/W (on 1 in² FR-4 board). The low RθJC enables high-power operation with external heatsinking, while RθJA reflects natural-convection performance - meaning 113.5 W can be dissipated at TC = 100°C, but only ~6.2 W at TA = 25°C without added copper area.
