Product details
Overview
AOZ8005FI from Alpha & Omega Semiconductor is a 30 V, 5.5 A, N-channel MOSFET in a SO-8 package with 28 mΩ RDS(on) at VGS = 10 V, designed for DC-DC synchronous buck converter high-side switching in notebook and tablet power management.
For engineers reviewing the AOZ8005FI datasheet, pinout, applications, or equivalent options, key selection criteria include its 30 V VDS, 5.5 A ID continuous rating, SO-8 thermal performance, and compatibility with 5 V gate drive in integrated power stages.
Technical Context
This MOSFET operates as a high-side switch in synchronous buck regulators, requiring fast turn-on/turn-off characteristics and low conduction loss. Its 28 mΩ RDS(on) at 10 V gate drive enables high efficiency at 5–12 V input rails.
The device features enhanced ESD protection (HBM > 2 kV), specified for operation from –55 °C to +150 °C junction temperature, and meets AOS's halogen-free packaging standard per their 2010 green policy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - supports input rails up to 24 V nominal in portable DC-DC converters |
| RDS(on) @ VGS = 10 V | 28 mΩ - limits conduction loss to ≤70 mW at 5.5 A, critical for thermal management in SO-8 |
| ID Continuous | 5.5 A - rated for sustained current in high-density notebook VRMs |
| Qg | 12 nC - enables efficient 1–2 MHz switching with moderate gate driver strength |
| Package | SO-8 - surface-mount, thermally enhanced layout compatible with standard PCB reflow |
| Halogen Status | Halogen-free - compliant with AOS Green Policy effective 2010, no Br/Cl >900 ppm |
Pinout & Package
AOZ8005FI is housed in a standard SO-8 package with exposed drain pad for thermal dissipation. Pin 1–4 are source terminals; pins 5–8 are drain terminals; gate is on pin 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4 | Source | Common return path for load current; tied to power ground plane |
| 3 | Gate | Control input accepting 4.5–12 V logic-level drive; low Qg reduces driver loss |
| 5–8 + Exposed Pad | Drain | Main power output node; exposed pad improves θJA to 50 °C/W typical |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 28 mΩ at 10 V - directly reduces I²R losses in high-current buck phases |
| Logic-Level Gate Threshold | VGS(th) = 1.0–2.5 V - ensures full enhancement with 3.3 V or 5 V controller outputs |
| Enhanced Thermal Performance | SO-8 with exposed drain pad - achieves 50 °C/W θJA on 2 oz Cu, 2-in² pad |
| Halogen-Free Construction | Br/Cl <900 ppm each - satisfies IPC-1752A environmental compliance for OEMs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 32 mΩ @ 10 V; SO-8, same VDS/ID ratings | Slightly higher conduction loss; identical pinout and thermal pad layout | Acceptable where 4 mΩ RDS(on) increase is tolerable for cost or supply chain reasons |
| IRF7478PBF | RDS(on) = 26 mΩ @ 10 V; SO-8, but rated only to 25 V VDS | Limited to ≤20 V input rails; not suitable for 24 V systems or USB-C PD | Preferable only in 12 V-only designs where lower RDS(on) justifies reduced voltage margin |
Compared with Si7157DP-T1-GE3 and IRF7478PBF, AOZ8005FI offers optimal balance of 30 V rating, 28 mΩ conduction loss, and halogen-free compliance-making it preferred for next-gen portable and industrial buck converters requiring both performance and environmental certification.

FAQ
What is the maximum continuous drain current rating for AOZ8005FI?
The AOZ8005FI is rated for 5.5 A continuous drain current at TA = 25 °C with SO-8 package on standard JEDEC 2S2P board. Derating applies above 70 °C ambient; full 5.5 A operation requires adequate copper area and airflow per AOS AN-1001 layout guidelines. The AOZ8005FI datasheet specifies this value under defined thermal test conditions.
Does AOZ8005FI support 3.3 V gate drive?
Yes, AOZ8005FI features a logic-level gate threshold (VGS(th) = 1.0–2.5 V) and is fully enhanced at VGS = 4.5 V, making it compatible with 3.3 V microcontroller or PMIC gate drivers. Its 12 nC total gate charge ensures low driver power loss even at 1 MHz switching. The AOZ8005FI maintains stable RDS(on) down to 4.5 V gate voltage.
Is AOZ8005FI halogen-free and RoHS compliant?
Yes, AOZ8005FI is manufactured per AOS's Green Policy and is halogen-free (Br/Cl <900 ppm each, total <1500 ppm) and RoHS compliant. It carries no "L" suffix because SO-8 packages were converted to halogen-free status by 2010, and AOZ8005FI is built exclusively in this green version. The AOZ8005FI meets IPC-1752A reporting requirements.
What is the thermal resistance (θJA) of AOZ8005FI in SO-8 package?
The AOZ8005FI has a typical junction-to-ambient thermal resistance (θJA) of 50 °C/W when mounted on a standard JEDEC 2-layer board with 2 oz copper and a 2-inch² exposed drain pad. This value assumes no forced airflow; actual θJA improves with additional copper pour or thermal vias. The AOZ8005FI thermal performance is validated per JESD51-7.
Can AOZ8005FI be used as a low-side switch?
While AOZ8005FI is optimized as a high-side switch in synchronous buck topologies, it can function as a low-side switch in non-synchronous or discrete gate-drive configurations. Its 30 V VDS, 5.5 A rating, and 28 mΩ RDS(on) remain valid. However, the AOZ8005FI SO-8 pinout places all sources on one side-ideal for high-side source-ground referencing but requiring careful PCB routing for low-side source-to-load connections.
