Product details
Overview
AONS62614 from Alpha & Omega Semiconductor is a 60V, 100A N-channel Trench Power MOSFET using AlphaSGT™ technology, optimized for high-frequency switching and synchronous rectification in DC-DC converters and motor drives, with RDS(ON) < 2.5 mΩ at VGS = 10 V and logic-level gate drive capability down to 4.5 V.
For engineers reviewing the AONS62614 datasheet, pinout, applications, or equivalent options, key selection considerations include its 0.85°C/W junction-to-case thermal resistance, 100% UIS-tested ruggedness, low gate charge (Qg(10V) = 64–90 nC), and DFN5x6 package suitability for high-power density board layouts.
Technical Context
The AONS62614 employs AlphaSGT™ (Alpha Silicon Gate Trench) technology to achieve ultra-low RDS(ON) while maintaining robust avalanche performance (EAS = 265 mJ, L = 0.3 mH) and fast switching (tD(on) = 7.5 ns, tf = 12.5 ns). Its gate threshold voltage (1.2–2.2 V at 25°C) enables reliable logic-level operation with standard 5 V or 3.3 V controllers.
Thermal design is supported by a low RθJC of 0.85°C/W and validated steady-state power dissipation up to 119 W at TC = 25°C. The device features integrated body diode with VSD = 0.67–1.0 V and Qrr = 92 nC, enabling efficient synchronous rectification without external Schottky replacement.
Key Specifications

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 IPP026N06N | RDS(ON) = 2.6 mΩ @ 10 V; higher Qg (105 nC); TO-220FP package with higher RθJA. | Less suitable for ultra-dense layouts; requires larger heatsink due to 1.5°C/W RθJC. | Preferred where through-hole mounting or legacy TO-220 footprint is required; lower cost per unit at medium volumes. |
| Vishay SiR626DP | RDS(ON) = 2.3 mΩ @ 10 V; slightly lower Qg (60 nC); same DFN5x6 package but non-RoHS-compliant lead finish. | Not suitable for new RoHS-compliant designs; identical thermal and electrical behavior otherwise. | Consider only if existing qualification allows non-halogen-free finish; otherwise AONS62614 offers superior compliance and consistency. |
Compared with IPP026N06N and SiR626DP, the AONS62614 delivers best-in-class RDS(ON) × Qg FOM in a RoHS/halogen-free DFN5x6 package, enabling higher power density and simpler thermal management-especially critical in space-constrained 48 V and server applications.

FAQ
What is the maximum continuous drain current rating for AONS62614?
The AONS62614 has a continuous drain current rating of 100 A at TC = 25°C, limited by package thermal capacity-not silicon. At TC = 100°C, the derated current is 42 A per the datasheet's Figure 13. This rating assumes proper PCB copper area and thermal vias to maintain case temperature.
Does AONS62614 support logic-level gate drive?
Yes, the AONS62614 supports true logic-level gate drive: its gate threshold voltage ranges from 1.2 V to 2.2 V at 25°C, and it achieves RDS(ON) < 3.4 mΩ at VGS = 4.5 V. This allows direct interfacing with 3.3 V or 5 V microcontrollers and PWM controllers without gate boosting.
Is AONS62614 suitable for synchronous rectification?
Yes, the AONS62614 is explicitly designed for synchronous rectification. Its low VSD (0.67–1.0 V), fast body diode recovery (trr = 26 ns, Qrr = 92 nC), and low RDS(ON) make it ideal for secondary-side switching in isolated DC-DC converters, replacing Schottky diodes to improve efficiency and reduce heat.
What is the thermal resistance from junction to case (RθJC) for AONS62614?
The AONS62614 has a typical junction-to-case thermal resistance (RθJC) of 0.85°C/W, measured from the die junction to the exposed drain pad. This value enables high-power dissipation-up to 119 W at TC = 25°C-and is critical for thermal design when mounting directly to a heatsink or thick copper plane.
Has AONS62614 been tested for unclamped inductive switching (UIS)?
Yes, every unit of AONS62614 undergoes 100% unclamped inductive switching (UIS) testing per JEDEC JESD22-A110. It is rated for EAS = 265 mJ at L = 0.3 mH and TJ = 25°C, confirming robustness against inductive energy spikes in motor drives and SMPS applications.
