Product details
Overview
AOD510 from Alpha & Omega Semiconductor is a 30V N-Channel Trench Power AlphaMOS (αMOS LV) discrete MOSFET optimized for high-efficiency DC/DC conversion. It delivers 70A continuous drain current at TC=25°C, <2.6mΩ RDS(ON) at VGS=10V, and <4mΩ at VGS=4.5V, enabling low conduction loss in server point-of-load and telecom isolated converter applications.
For engineers reviewing the AOD510 datasheet, pinout, applications, or equivalent options, key selection criteria include its 100% UIS-tested ruggedness, low gate charge (Qg=44–60nC at 10V), 0.9–2Ω gate resistance, 2719pF input capacitance, and TO-251A (IPAK) package thermal performance with RθJC=2.5°C/W.
Technical Context
The AOD510 employs Alpha & Omega's latest αMOS LV trench technology to achieve ultra-low on-resistance at logic-level gate drive (4.5V), supporting efficient synchronous rectification and high-side switching in compact power stages. Its 100% Rg-tested gate resistance ensures consistent switching timing across production lots.
Designed for unclamped inductive switching (UIS) reliability, the AOD510 sustains 280A pulsed drain current and 37A avalanche current (L=0.1mH), with body-diode reverse recovery time trr=19.6ns and Qrr=42.7nC-critical for minimizing turn-off losses in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30V maximum drain-source voltage - defines safe operating range in 12V/24V input DC/DC stages |
| ID (TC=25°C) | 70A continuous drain current - supports high-current POL rails without external heatsinking |
| RDS(ON) @ VGS=10V | <2.6mΩ - reduces I²R conduction loss below 13mW at 20A, improving full-load efficiency |
| RDS(ON) @ VGS=4.5V | <4mΩ - enables direct drive from 3.3V/5V controllers without level-shifting circuitry |
| Qg (10V) | 44–60nC - determines gate driver power requirement and switching speed in 300kHz–1MHz converters |
| trr / Qrr | 19.6ns / 42.7nC - minimizes body-diode commutation loss during dead-time in synchronous buck converters |
| RθJC | 2.5°C/W - allows 36W steady-state power dissipation at TC=25°C, supporting high-density thermal design |
Pinout & Package
Package: TO-251A (IPAK), surface-mount, single-drain tab configuration with exposed drain pad for thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3803PbF | RDS(ON)=3.0mΩ @ 10V; Qg=54nC; TO-220AB package; higher RθJA (62°C/W) | Larger footprint and lower thermal efficiency limit usable current density in space-constrained POL designs | Prefer AOD510 where PCB area and thermal resistance are constrained; IRL3803PbF suits legacy through-hole layouts |
| SiR872DP | RDS(ON)=2.3mΩ @ 10V; Qg=51nC; PowerPAK SO-8 package; RθJC=3.0°C/W | Lower RDS(ON) but higher gate charge and inferior thermal path limits peak current handling in high-duty-cycle operation | Choose SiR872DP only when SO-8 footprint compatibility is mandatory; AOD510 offers better thermal headroom for sustained 70A loads |
Compared with IRL3803PbF and SiR872DP, the AOD510 provides superior thermal performance (RθJC=2.5°C/W) and logic-level drive capability (<4mΩ @ 4.5V), making it optimal for high-current, surface-mount DC/DC converters where thermal management and gate drive simplicity are critical.

FAQ
What is the maximum continuous drain current rating for the AOD510 at 100°C case temperature?
The AOD510 supports 30A continuous drain current at TC=100°C, derated from its 70A rating at TC=25°C per the current de-rating curve in Figure 13 of the datasheet. This value reflects package thermal limits-not silicon capability-and assumes proper PCB copper area and airflow per AOS's test conditions (1in² FR-4, 2oz Cu).
Does the AOD510 support 3.3V gate drive in practical applications?
The AOD510 has a gate threshold voltage VGS(th) of 1.2–2.2V (typical 1.7V), and its RDS(ON) remains below 4mΩ at VGS=4.5V. While 3.3V drive yields measurable on-resistance (~5.8mΩ estimated from Figure 5), full-rated performance requires ≥4.5V. For 3.3V systems, verify conduction loss and thermal margin using the normalized RDS(ON) vs. VGS curve.
Is the AOD510 qualified for automotive applications?
No-the AOD510 is explicitly designed and qualified for the consumer market per its datasheet disclaimer. It is not AEC-Q101 qualified, and AOS prohibits its use in life-support or safety-critical automotive systems. For automotive ADAS power supplies, consider AOS's AUIRF series or other AEC-Q101-compliant alternatives.
What is the significance of 100% Rg testing for the AOD510?
100% Rg (gate resistance) testing ensures every AOD510 unit meets the specified 0.9–2Ω gate resistance tolerance. This guarantees consistent gate charging/discharging behavior across production lots, which is essential for predictable switching timing, reduced EMI variation, and reliable paralleling in multi-phase power stages.
How does the AOD510's body-diode performance compare to standard MOSFETs in synchronous rectification?
The AOD510's body diode exhibits trr=19.6ns and Qrr=42.7nC at IF=20A, dI/dt=500A/µs-significantly faster than older TrenchFETs. This reduces reverse recovery loss during dead-time conduction, lowering temperature rise by ~5–8°C in synchronous buck converters operating above 300kHz, as confirmed by AOS's application note AN-8022.
