Product details
Overview
AOT414 from Alpha & Omega Semiconductor is a 100V, 43A N-channel MOSFET in TO-220 package, featuring <25 mΩ RDS(ON) at VGS=10V, 28 nC total gate charge, and 100% UIS-tested ruggedness. It serves as a high-efficiency power switch in DC-DC converters, motor drives, and industrial load switching circuits.
For engineers reviewing the AOT414 datasheet, pinout, applications, or equivalent options, key selection criteria include its 100V breakdown rating, low 1.3°C/W junction-to-case thermal resistance, avalanche-rated operation, and compatibility with standard gate drivers in hard-switching topologies.
Technical Context
The AOT414 employs Alpha & Omega's proprietary SDMOS™ trench technology to achieve simultaneous optimization of conduction loss (RDS(ON)) and switching performance (Qg, Qgd). Its 6–14 nC gate-drain charge supports fast, controlled turn-off with reduced voltage overshoot during inductive switching.
Rated for 175°C maximum junction temperature and 100% tested for unclamped inductive switching (UIS), the device delivers robust operation under transient overloads. Thermal design leverages a low 1.3°C/W RθJC, enabling high-power dissipation when mounted on heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Withstands up to 100V drain-source blocking voltage, suitable for 48V bus and 100V industrial input systems. |
| ID (VGS=10V) | 43 A - Continuous drain current at TC=25°C enables high-current switching without derating in heatsinked designs. |
| RDS(ON) (VGS=10V) | <25 mΩ - Low conduction loss reduces I²R heating in high-duty-cycle applications like PWM motor control. |
| Qg (10V) | 14–42 nC - Gate charge range informs driver sizing; typical 28 nC supports efficient 100 kHz–500 kHz switching with 3Ω–10Ω gate resistors. |
| RθJC | 1.3 °C/W - Enables >58 W steady-state power dissipation with modest heatsinking, critical for compact industrial power modules. |
| EAR | 54 mJ - Repetitive avalanche energy rating ensures reliable operation during inductive turn-off transients without external snubbers. |
Pinout & Package
Package: TO-220 (3-lead, through-hole, isolated tab). Tab is Drain-connected; leads are Gate (left), Drain (center), Source (right) in bottom-view orientation per datasheet Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts 0–10V logic-level drive; 0.3–1.0 Ω gate resistance enables precise switching speed tuning. |
| D (Drain) | High-side power terminal | Connected to internal die backside and metal tab; requires electrical isolation if mounted to heatsink. |
| S (Source) | Reference/return path | Serves as common return for gate drive and load current; defines local ground reference for driver IC placement. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guarantees minimum 54 mJ repetitive avalanche energy, eliminating need for external clamping in inductive loads. |
| Low Qgd/Qg ratio | Typical 0.36 (10 nC / 28 nC) improves Miller immunity and reduces risk of spurious turn-on in high-dV/dt environments. |
| Body diode soft recovery | trr = 20–38 ns with softness factor S ≥ 2.5 minimizes voltage ringing and EMI in synchronous rectification. |
| 100% Rg tested | Ensures gate resistance between 0.3 Ω and 1.0 Ω, enabling predictable gate drive timing and layout-independent switching behavior. |
Applications
| DC-DC Converters | Motor Drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP110N10F7 | 100V, 110A, RDS(ON) = 9.5 mΩ @ 10V, Qg = 65 nC, TO-220FP package (non-isolated tab) | Higher current rating but larger gate charge; requires stronger gate driver and tighter thermal management. | Prefer when higher peak current (>60A) is needed and PCB layout allows non-isolated mounting. |
| IRF540N | 100V, 33A, RDS(ON) = 44 mΩ @ 10V, Qg = 71 nC, TO-220 package | Higher conduction loss and slower switching; lacks UIS and Rg testing. | Select only for cost-sensitive, low-frequency (<50 kHz), non-avalanche-critical legacy designs. |
Compared with STP110N10F7 and IRF540N, the AOT414 offers optimal balance of low RDS(ON), moderate Qg, and production-grade ruggedness-making it ideal for new 100V industrial power designs where efficiency, reliability, and driver simplicity are prioritized over raw current headroom.

FAQ
What is the maximum continuous drain current rating for the AOT414 at 100°C case temperature?
The AOT414 supports 28 A continuous drain current at TC = 100°C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limits under sustained operation and must be verified against actual board-level thermal resistance and ambient conditions. The AOT414 datasheet confirms this rating applies to steady-state conditions with proper heatsinking.
Does the AOT414 have a fully rated body diode for synchronous rectification?
Yes, the AOT414 features a fully characterized body diode with 40 A maximum continuous current (IS), 0.66 V typical forward voltage (VSD), and soft reverse recovery (trr = 20–38 ns). These parameters are measured and guaranteed across temperature, making the AOT414 suitable for synchronous rectifier roles in DC-DC converters where diode conduction occurs regularly.
Is the AOT414 pin-compatible with the AOT414L variant?
Yes, the AOT414 and AOT414L are electrically identical per the manufacturer's documentation, sharing identical absolute maximum ratings, electrical characteristics, thermal parameters, and pinout. The "L" suffix denotes a lead-free, RoHS-compliant version with identical TO-220 mechanical form factor and terminal configuration.
What gate voltage range is required to fully enhance the AOT414?
The AOT414 achieves full enhancement between VGS = 7 V and 10 V, with gate threshold voltage (VGS(th)) specified from 2.0 V to 4.0 V. For reliable low-RDS(ON) operation, a minimum VGS of 7 V is recommended; at 10 V, RDS(ON) is guaranteed <25 mΩ. Driving below 5 V risks incomplete turn-on and excessive conduction loss.
How is the 100% UIS test performed on the AOT414?
The AOT414 undergoes 100% unclamped inductive switching (UIS) testing per JEDEC JESD24-11, using standardized circuit conditions (L = 0.1 mH, IAR = 40 A, VDD = 100 V). Each unit is validated to withstand ≥54 mJ single-pulse avalanche energy without parameter shift or failure, ensuring robustness in real-world inductive turn-off events.
