Product details
Overview
AO7417 from Alpha & Omega Semiconductor is a 20V P-Channel MOSFET in SOT-363 (SC-70-6) package, featuring RDS(ON) < 80 mΩ at VGS = −4.5 V, gate threshold voltage of −0.5 to −1.0 V, and operation down to 1.5 V gate drive. It delivers −2 A continuous drain current and is optimized for low-voltage buck converter high-side switching.
For engineers reviewing the AO7417 datasheet, pinout, applications, or equivalent options, key selection criteria include its trench-based low-RDS(ON) performance at ultra-low gate voltages, thermal resistance (RθJA = 160 °C/W), and compact 6-pin SC-70 footprint suitable for space-constrained DC-DC power stages.
Technical Context
The AO7417 employs advanced trench-gate MOSFET technology to achieve enhanced conduction efficiency and fast switching with minimal gate charge (Qg = 8.5–11 nC). Its −0.65 V typical gate threshold enables reliable turn-on with 1.8 V logic-level signals, supporting direct interface with low-voltage microcontrollers.
Designed for synchronous rectification and high-side switching in buck converters, the device integrates a body diode with reverse recovery time (trr) of 37–49 ns and Qrr = 27 nC, enabling efficient freewheeling without external Schottky diodes in many applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum drain-source blocking voltage for 12 V input rail designs with margin. |
| RDS(ON) @ VGS = −4.5 V | < 80 mΩ - Enables ≤ 320 mW conduction loss at −2 A, critical for thermally constrained layouts. |
| Qg | 8.5–11 nC - Low total gate charge reduces driver power and switching losses in 500 kHz–1 MHz converters. |
| tr/tf | 36 ns / 56 ns - Fast edge rates support high-frequency operation while limiting EMI generation. |
| RθJA | 160 °C/W - Measured on 1 in² 2 oz copper FR-4; defines maximum power dissipation (0.4 W) at TA = 70 °C. |
| VGS(th) | −0.5 to −1.0 V - Ensures robust turn-on with 1.8 V GPIOs and eliminates need for level-shifting circuitry. |
Pinout & Package
Package: SC-70-6 (SOT-363), 1.6 mm × 2.9 mm × 1.1 mm, surface-mount, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts logic-level gate drive down to 1.5 V; requires no external pull-down for default-off behavior. |
| 2 (S) | Source | Reference node for gate drive; connected to output rail in high-side switch configuration. |
| 3 (D) | Drain | High-side switch output; connects to input rail (e.g., 12 V); carries full load current during conduction. |
| 4 (D) | Drain | Internally paralleled with Pin 3 to reduce package inductance and improve current sharing in dual-drain layout. |
| 5 (S) | Source | Second source terminal; tied to Pin 2 externally to minimize source inductance and stabilize switching. |
| 6 (G) | Gate | Redundant gate connection; used for Kelvin gate routing or improved gate loop inductance control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low gate threshold | VGS(th) = −0.65 V typ supports direct 1.8 V MCU GPIO drive without level shifters. |
| Trench MOSFET architecture | Delivers <80 mΩ RDS(ON) at −4.5 V and <125 mΩ at −1.8 V, enabling high-efficiency low-VIN conversion. |
| Dual-drain/dual-source package | SOT-363 layout minimizes parasitic inductance-critical for stable high-frequency switching and reduced ringing. |
| Low Qgd/Qg ratio | Qgd = 2.1 nC / Qg = 10 nC ≈ 0.21 improves hard-switching immunity and reduces Miller-induced shoot-through risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2301DS-T1-GE3 | RDS(ON) = 90 mΩ @ −4.5 V; VGS(th) = −0.7 V min; SOT-23-3 package (single drain/source). | Lacks dual-drain layout and Kelvin gate; higher RDS(ON) increases conduction loss by ~12% at 2 A. | Preferred where board space is extremely limited and dual-source routing is not required. |
| DMG1012T-7 | RDS(ON) = 85 mΩ @ −4.5 V; VGS(th) = −0.5 V min; SOT-563 (same pin count but different pinout). | Non-compatible pinout (G-S-D vs AO7417's G-S-D-D-S-G); requires PCB redesign. | Consider only if thermal performance (RθJA = 150 °C/W) outweighs layout impact. |
Compared with Si2301DS-T1-GE3 and DMG1012T-7, the AO7417 offers lower RDS(ON), superior gate-drive compatibility with 1.8 V systems, and a dual-drain/dual-source layout that reduces switching noise-making it optimal for high-frequency, low-noise buck converters where layout integrity is critical.

FAQ
What is the maximum continuous drain current for the AO7417 at 70°C ambient temperature?
The AO7417 supports −2 A continuous drain current at TA = 70°C, based on its 0.4 W power dissipation rating and 160 °C/W junction-to-ambient thermal resistance. This rating assumes operation on a standard 1 in² 2 oz copper PCB in still air; actual current capability may increase with enhanced heatsinking or forced airflow. The AO7417 datasheet specifies this value under steady-state conditions with VGS = −4.5 V.
Can the AO7417 be driven directly by a 1.8 V microcontroller GPIO without a level shifter?
Yes-the AO7417 has a typical gate threshold voltage of −0.65 V and guaranteed turn-on at VGS = −1.0 V, making it fully compatible with 1.8 V logic outputs. At VGS = −1.8 V, RDS(ON) remains < 125 mΩ, delivering usable conduction performance. This eliminates external level-shifting components in the AO7417 gate drive path.
What is the significance of the dual-drain and dual-source pins on the AO7417?
The AO7417's SOT-363 package features two drain pins (3 and 4) and two source pins (2 and 5) to reduce package parasitic inductance and improve current distribution. This layout lowers switching ringing, enhances stability in high-frequency buck converters, and simplifies Kelvin source routing for accurate gate drive referencing-key advantages not available in standard SOT-23 or SOT-563 MOSFETs like the AO7417 alternatives.
Does the AO7417 include an integrated body diode, and what are its recovery characteristics?
Yes-the AO7417 integrates a monolithic body diode with forward voltage VSD = −0.7 to −1.0 V at −1 A. Its reverse recovery time trr is 37–49 ns and Qrr = 27 nC under IF = −2 A and dI/dt = 100 A/μs conditions. These values support efficient freewheeling in synchronous buck topologies without requiring external Schottky diodes.
How does the AO7417's gate charge compare to similar P-channel MOSFETs, and why does it matter?
The AO7417 has Qg = 8.5–11 nC and Qgd/Qg ≈ 0.21-lower than many competing devices (e.g., Si2301DS: Qg = 12 nC, Qgd/Qg ≈ 0.27). This reduces gate driver power consumption and improves switching speed consistency, especially important in 1 MHz+ buck converters where gate drive losses scale linearly with Qg and frequency.
