Product details

Overview

AOD2910 from Alpha & Omega Semiconductor is a 100V N-Channel Trench MOSFET optimized for high-frequency switching, with R_DS(ON) < 24 mΩ at V_GS = 10 V, 31 A continuous drain current, and 100% UIS-tested ruggedness. It serves as a primary switch in boost converters and synchronous rectifier in consumer/telecom power supplies.

For engineers reviewing the AOD2910 datasheet, pinout, applications, or equivalent options, key selection criteria include its low gate charge (Q_g = 16.5–25 nC), ultra-low C_iss/C_oss (1190 pF / 95 pF), and TO-252 (DPAK) thermal performance enabling compact, efficient SMPS designs.

Technical Context

The AOD2910 employs trench-gate MOSFET architecture to simultaneously minimize conduction loss (via sub-24 mΩ R_DS(ON)) and switching loss (via low C_iss, C_oss, and Q_g). Its 100% UIS and R_g testing ensures robustness under unclamped inductive switching stress and gate drive consistency.

Thermally, it delivers 53.5 W power dissipation at T_A = 70°C with R_θJA = 50°C/W (FR-4, 2 oz Cu), and supports junction temperatures up to 175°C. The body diode exhibits V_SD = 0.72–1.0 V and Q_rr = 145 nC, enabling reliable synchronous rectification without external Schottky replacement.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Supports input rails up to 85 V DC in offline boost or 48 V telecom systems with margin.

R_DS(ON) (V_GS = 10 V)	< 24 mΩ - Limits conduction loss to < 0.23 W at 31 A, reducing heatsink requirements.
Q_g (10 V)	16.5–25 nC - Allows fast turn-on with moderate gate driver strength (e.g., TC4427), minimizing switching loss.
C_iss/C_oss	1190 pF / 95 pF - Low output capacitance enables high-efficiency operation above 300 kHz in ZVS/ZCS topologies.
T_J max	175 °C - Permits operation in sealed enclosures or high-ambient industrial environments with derating.
E_AS	Not specified in absolute value but 100% UIS tested - Confirms single-pulse avalanche energy handling per JEDEC JESD24-11.

Pinout & Package

Package: TO-252 (DPAK), surface-mount, exposed drain pad for enhanced thermal conduction to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Receives PWM signal; low R_g (0.5–1.7 Ω) minimizes gate oscillation risk with standard 10–22 Ω series resistors.
S (Source)	Reference node	Common return path for load current and gate drive; ties to power ground plane for low-noise switching.
D (Drain)	Power output node	Connected to high-side switch node or inductor; large copper area required for thermal and current handling.

Key Features

Feature	Design Value
Trench MOSFET technology	Delivers best-in-class R_DS(ON) × Q_g figure-of-merit for high-frequency efficiency in <500 kHz SMPS.
100% UIS tested	Guarantees survival under worst-case inductive turn-off transients without external snubbers in boost or flyback.
Low C_oss (95 pF)	Reduces turn-off energy loss and improves light-load efficiency in resonant and quasi-resonant converters.
Body diode Q_rr = 145 nC	Enables stable synchronous rectification with predictable reverse recovery timing and minimal voltage overshoot.
TO-252 thermal resistance	R_θJC = 2.8°C/W allows >50 W dissipation with minimal heatsink when mounted on ≥1 in² 2 oz Cu PCB.

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	R_DS(ON) = 11.5 mΩ @ 10 V, higher Q_g (42 nC), TO-220 package	Requires heatsink and larger board area; better for lower-frequency, higher-current designs	Select when thermal budget permits discrete heatsinking and lower R_DS(ON) outweighs gate drive complexity.
IRF540N	R_DS(ON) = 44 mΩ @ 10 V, older planar process, TO-220	Higher conduction loss limits use to <15 A continuous; not UIS-rated	Choose only for cost-sensitive, low-frequency (<100 kHz), non-ruggedized legacy designs where efficiency is secondary.

Compared with STP110N10F7 and IRF540N, the AOD2910 offers superior high-frequency efficiency due to its trench architecture, surface-mount TO-252 footprint, and guaranteed UIS capability-making it optimal for space-constrained, high-reliability power conversion where thermal management and transient robustness are critical.

FAQ

What is the maximum continuous drain current for the AOD2910 at 100°C case temperature?

The AOD2910 supports 80 A pulsed drain current, but its continuous drain current at T_C = 100°C is rated at 21.5 A per the Absolute Maximum Ratings table. This value reflects thermal limits of the TO-252 package under steady-state conditions and must be validated against actual PCB layout and ambient airflow. The AOD2910 datasheet specifies this limit explicitly in the "Continuous Drain Current" row under "TC=100°C".

Does the AOD2910 have a fully characterized body diode for synchronous rectification?

Yes-the AOD2910 body diode is fully characterized with V_SD = 0.72–1.0 V at I_S = 1 A and reverse recovery charge Q_rr = 145 nC at I_F = 20 A, dI/dt = 500 A/ms. These parameters are measured and published in the Electrical Characteristics table, confirming suitability for synchronous rectifier applications without external diodes.

Is the AOD2910 RoHS-compliant and halogen-free?

Yes-the AOD2910 meets RoHS Directive 2011/65/EU and is halogen-free per AOS specification. This compliance is documented in the manufacturer's official product change notices and material declarations available at aosmd.com, and applies to all standard production lots of the AOD2910.

What is the gate threshold voltage range for the AOD2910, and how does it affect 4.5 V logic-level drive?

The AOD2910 has a gate threshold voltage V_GS(th) of 1.6–2.7 V, ensuring reliable turn-on with 4.5 V logic-level gate drivers. At V_GS = 4.5 V, its R_DS(ON) remains < 33 mΩ-low enough for efficient operation in 3.3 V/5 V-controlled SMPS. This is confirmed in the Static Parameters table under "R_DS(ON) (at V_GS=4.5V)".

Can the AOD2910 replace the AOD2916 in an existing design?

No-the AOD2910 and AOD2916 are distinct parts: AOD2910 is a 100 V, 31 A device with R_DS(ON) < 24 mΩ, while AOD2916 is a 150 V, 25 A part with higher R_DS(ON). They share TO-252 packaging and pinout, but voltage rating and conduction loss differ significantly. Substitution requires full revalidation of voltage stress, thermal performance, and gate drive compatibility for the AOD2910.
