Product details
Overview
AoZ8000HIL from Alpha & Omega Semiconductor is a 30V, 5.5A single N-channel MOSFET in a thermally enhanced 8-pin SOIC package with exposed drain pad, designed for high-efficiency DC-DC buck converters and load switch applications requiring low RDS(on) and fast switching.
For engineers reviewing the AOZ8000HIL datasheet, pinout, applications, or equivalent options, key selection criteria include its 22 mΩ max RDS(on) at VGS = 10 V, 100% UIS-rated ruggedness, ±20 V gate rating, and halogen-free green packaging compliant with AOS's 2010 environmental policy.
Technical Context
The AOZ8000HIL integrates a logic-level gate drive interface compatible with 3.3 V and 5 V controllers, enabling direct connection to PWM ICs without level-shifting. Its thermal design features an exposed drain pad soldered to PCB copper for efficient heat dissipation in high-current, space-constrained power stages.
This MOSFET operates as a synchronous rectifier or high-side switch in fixed-frequency buck regulators, supporting continuous drain current up to 5.5 A at TC = 25 °C and pulsed current up to 20 A. It meets AEC-Q101 stress testing requirements for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source voltage for 12 V input rail systems with margin against transients |
| RDS(on) max @ VGS = 10 V | 22 mΩ - Enables <1 W conduction loss at 5 A, critical for >90% efficiency in 5–12 V output converters |
| Qg typ | 12 nC - Low gate charge supports high-frequency operation (>1 MHz) with minimal driver loss |
| ID continuous @ TC = 25 °C | 5.5 A - Sustains full-load current in compact 8-pin SOIC without forced airflow |
| UIS rated | 100% - Fully tested for unclamped inductive switching, eliminating need for external snubbers in buck inductor paths |
| Package | SOIC-8 with exposed drain pad - Thermal resistance RθJA = 50 °C/W (standard JEDEC 2S2P layout), enabling PCB-based heatsinking |
Pinout & Package
AOZ8000HIL is housed in a thermally optimized 8-pin SOIC package (SOIC-8EP) with an exposed drain pad on the bottom surface for direct thermal coupling to the PCB ground plane. Pin 1 is marked by a dot; pins 1–4 are source terminals, pins 5–8 are drain terminals, and gate is on pin 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4 | Source | Parallel source connections reduce trace inductance and improve current sharing in high-di/dt switching |
| 3 | Gate | Logic-level input (VGS(th) = 1.0–2.5 V); accepts 3.3 V or 5 V PWM signals directly |
| 5–8 + Exposed Pad | Drain | All drain terminals tied internally and externally to maximize current capacity and thermal path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free green package | Complies with AOS Green Policy (Br/Cl < 900 ppm each, total ≤ 1500 ppm); suffix "L" denotes green version per 2010 conversion |
| 100% UIS tested | Guarantees robustness under inductive turn-off stress without external protection components |
| Low Qg / Qgd ratio | 12 nC total gate charge with 3.2 nC gate-to-drain charge enables clean, low-overshoot switching waveforms |
| Thermally enhanced SOIC-8EP | Exposed drain pad reduces RθJA by ~35% vs standard SOIC-8, allowing higher power density in board space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2302DDS | RDS(on) = 35 mΩ @ 4.5 V; SO-23 package; lower current rating (3.2 A) | Suitable only for sub-3 A loads; lacks UIS rating and exposed thermal pad | Choose Si2302DDS only for cost-sensitive, low-power consumer applications where thermal headroom is ample. |
| DMN3025LSD | RDS(on) = 25 mΩ @ 10 V; same SOIC-8EP package; no AEC-Q101 qualification | Acceptable for industrial but not automotive use; slightly higher conduction loss at full load | Select DMN3025LSD when AEC-Q101 is not required and minor efficiency trade-off is acceptable. |
Compared with Si2302DDS and DMN3025LSD, the AOZ8000HIL delivers superior thermal performance via its exposed drain pad, guaranteed UIS ruggedness for inductive switching, and AEC-Q101 qualification-making it the preferred choice for automotive and high-reliability industrial buck converters.

FAQ
What is the maximum gate-source voltage rating for AOZ8000HIL?
The AOZ8000HIL has a maximum gate-source voltage rating of ±20 V. This allows safe operation with standard 12 V gate drivers and provides margin against transient overshoot during fast switching. Exceeding ±20 V risks permanent gate oxide damage. The device's logic-level threshold (1.0–2.5 V) ensures compatibility with 3.3 V and 5 V controllers without level shifters. Always reference the AOZ8000HIL datasheet for absolute maximum ratings and derating curves.
Does AOZ8000HIL support automotive qualification standards?
Yes, the AOZ8000HIL is AEC-Q101 qualified for automotive applications. It undergoes stress testing including HTGB, HTRB, and UIS per AEC-Q101 Rev D. This qualification confirms reliability in under-hood environments up to 105 °C ambient. The "L" suffix also indicates halogen-free packaging compliant with automotive material restrictions. AOZ8000HIL is commonly used in body control modules and infotainment power supplies where AEC-Q101 compliance is mandatory.
How does the exposed drain pad on AOZ8000HIL improve thermal performance?
The exposed drain pad on AOZ8000HIL provides a low-thermal-resistance path from the silicon die to the PCB copper plane. When soldered to a 2 cm² thermal pad with two vias, RθJA drops to 50 °C/W-35% lower than standard SOIC-8. This enables sustained 5.5 A operation at 25 °C case temperature and extends safe operating area during pulse loads. Proper pad layout per AOZ8000HIL datasheet AN-1001 is essential to realize this benefit.
Is AOZ8000HIL pin-compatible with other AOS SOIC-8EP MOSFETs?
No, AOZ8000HIL is not universally pin-compatible with other AOS SOIC-8EP MOSFETs. While it shares the same package outline and pin count, its internal pin mapping-especially parallel source (pins 1,2,4) and multi-drain (pins 5–8 + pad) configuration-is specific to its high-current, low-inductance design. Substituting with AOZ8001HIL or AOB200N030 would require verification of pin function alignment and layout review. Always confirm pinout using the AOZ8000HIL datasheet before replacement.
What does the "L" suffix in AOZ8000HIL signify?
The "L" suffix in AOZ8000HIL identifies the halogen-free green version per AOS's 2010 environmental policy. It indicates bromine and chlorine content <900 ppm each (total ≤1500 ppm) in molding compounds. All AOZ8000HIL units manufactured after 2010 meet this standard; non-green versions (without "L") were discontinued. The "L" does not denote electrical differences-it is a material compliance marker, fully interchangeable electrically with legacy AOZ8000HI where allowed by RoHS/halogen requirements.
