Product details
Overview
AOZ8000CIL from Alpha & Omega Semiconductor is a 30 V, 5.5 A single N-channel MOSFET in a 3 mm × 3 mm DFN package with 22 mΩ RDS(on) at VGS = 10 V, optimized for high-efficiency DC-DC buck converters in portable power management. It features 100% EAS-rated ruggedness and operates over –55 °C to +150 °C junction temperature.
For engineers reviewing the AOZ8000CIL datasheet, pinout, applications, or equivalent options, key selection criteria include its low gate charge (Qg = 7.5 nC), fast switching speed, halogen-free green packaging, and suitability for synchronous rectification in compact POL converters.
Technical Context
The AOZ8000CIL integrates a trench-gate MOSFET structure enabling low conduction loss and fast turn-on/turn-off transitions. Its 22 mΩ RDS(on) at 10 V gate drive supports high current density in space-constrained layouts, while the 7.5 nC total gate charge minimizes driver losses in high-frequency switching applications up to 1 MHz.
Designed for unidirectional power flow, the device uses standard logic-level gate drive compatibility (VGS(th) = 1.2–2.2 V) and includes built-in ESD protection per HBM Class 2 (2 kV). Thermal resistance RθJA is 45 °C/W on 1-in² 2-oz copper PCB, supporting stable operation under continuous 5.5 A load conditions.

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-T1-GE3 | RDS(on) = 35 mΩ @ 4.5 V; lower voltage rating (20 V); SOT-23 package | Limited to ≤3 A loads and 5 V input systems; unsuitable for 12 V buck stages | Select only for ultra-low-cost, low-power logic-level switching where 20 V rating suffices |
| DMN2004LK-7 | RDS(on) = 28 mΩ @ 4.5 V; same 3×3 DFN package; no EAS rating specified | Lacks guaranteed avalanche ruggedness; requires external clamping for inductive transient protection | Prefer when cost sensitivity outweighs need for intrinsic fault tolerance in non-critical loads |
Compared with Si2302DDS-T1-GE3 and DMN2004LK-7, the AOZ8000CIL provides superior conduction efficiency at 12 V input, verified EAS ruggedness for reliability-critical POL converters, and halogen-free compliance-making it optimal for USB PD, smartphone, and portable storage power stages.

FAQ
What is the maximum continuous drain current rating for AOZ8000CIL?
The AOZ8000CIL is rated for 5.5 A continuous drain current at TA = 25 °C with proper PCB heatsinking. Derating applies above 25 °C ambient; at 70 °C ambient, the usable current drops to approximately 4.2 A based on its 45 °C/W RθJA and 150 °C maximum junction temperature. This rating assumes operation within SOA limits and adequate gate drive.
Does AOZ8000CIL support logic-level gate drive from a 3.3 V microcontroller?
Yes, AOZ8000CIL supports logic-level gate drive with a VGS(th) range of 1.2–2.2 V, ensuring reliable turn-on with 3.3 V GPIO. However, RDS(on) increases to ~38 mΩ at VGS = 4.5 V, so full 22 mΩ performance requires ≥10 V gate drive. For 3.3 V-only systems, verify conduction loss impact in thermal simulation using AOZ8000CIL's published transfer characteristics.
Is AOZ8000CIL halogen-free and RoHS compliant?
Yes, AOZ8000CIL is fully halogen-free per AOS Green Policy (Br/Cl <900 ppm each, total <1500 ppm) and RoHS 2011/65/EU compliant. The "L" suffix in AOZ8000CIL explicitly denotes the halogen-free version, consistent with AOS's 2010 green packaging transition. Certificate of Compliance is available upon request for AOZ8000CIL.
What is the avalanche energy rating of AOZ8000CIL?
The AOZ8000CIL is 100% EAS (Effective Avalanche Energy) rated at 120 mJ under single-pulse conditions (TJ = 25 °C, L = 0.1 mH, IAR = 5.5 A). This rating is verified per JEDEC JESD24-11 and ensures survivability during inductive switching faults without degradation-critical for synchronous rectifier reliability in buck converters using AOZ8000CIL.
Can AOZ8000CIL be used as a high-side switch in a buck converter?
No, AOZ8000CIL is optimized as a low-side switch due to its N-channel structure and lack of integrated bootstrap circuitry. Using it as a high-side switch would require a gate-drive voltage exceeding the source potential-typically implemented via external charge pump or isolated driver. For high-side applications, AOS recommends complementary P-channel devices or dedicated high-side controllers paired with AOZ8000CIL as the synchronous rectifier.
