Product details
Overview
AOD2HC60 from Alpha & Omega Semiconductor is a 600 V, 2.5 A N-channel high-voltage MOSFET in TO-252 (DPAK) package, featuring RDS(ON) ≤ 2 Ω at VGS = 10 V, 7.6 nC typical gate charge, and 100% UIS-tested ruggedness-designed for primary-side switching in offline AC-DC power supplies.
For engineers reviewing the AOD2HC60 datasheet, pinout, applications, or equivalent options, key selection criteria include avalanche energy rating (132 mJ), dv/dt ruggedness (100 V/ns), body-diode recovery performance (Qrr = 2.1 µC), and thermal resistance (RθJC = 1.7 °C/W) for reliable operation in compact, high-efficiency flyback and LLC converters.
Technical Context
The AOD2HC60 employs a high-voltage trench-gate process optimized for low conduction loss and fast switching in discontinuous conduction mode (DCM) and quasi-resonant (QR) flyback topologies. Its 700 V VDS rating at TJ = 150 °C ensures margin under surge conditions, while guaranteed unclamped inductive switching (UIS) supports robust startup and fault handling.
Dynamic parameters-including Ciss = 466 pF, Crss = 1.3 pF, and tr = 14 ns-enable efficient gate drive with minimal Miller-induced oscillation. The device's 0.78–1.0 V body-diode forward voltage and 183 ns reverse recovery time support synchronous rectification compatibility in secondary-side designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V maximum drain-source voltage; supports 400 VAC input with full surge margin in universal-input SMPS. |
| RDS(ON) | ≤ 2 Ω at VGS = 10 V, ID = 0.8 A; enables low conduction loss in <30 W primary-switching applications. |
| Qg | 7.6 nC typical total gate charge; reduces driver power loss and simplifies gate-drive design with 25 Ω resistor. |
| EAS | 132 mJ single-pulse avalanche energy; ensures reliable operation during output short-circuit or overload events. |
| RθJC | 1.7 °C/W junction-to-case thermal resistance; allows direct heatsinking to PCB copper or small external heatsink. |
| dv/dt ruggedness | 100 V/ns minimum; prevents spurious turn-on in high-noise, high-dV/dt environments like PFC stages. |
| Qrr | 2.1 µC body-diode reverse recovery charge; minimizes switching loss and EMI when used with fast-recovery diodes. |
Pinout & Package
Package: TO-252 (DPAK), surface-mount, exposed drain pad for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal; requires ≥10 V drive for full enhancement; 6.3 Ω internal gate resistance limits ringing. |
| D | Drain | Main current path; electrically connected to exposed backside pad; must be routed over large copper area for thermal management. |
| S | Source | Reference node for gate drive; connects to primary ground; forms return path for body-diode current during freewheeling. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guaranteed avalanche capability up to 132 mJ eliminates need for external snubbers in cost-sensitive flyback designs. |
| Low Crss (1.3 pF) | Minimizes Miller feedback, enabling stable operation at high dV/dt without gate clamping circuits. |
| Exposed drain pad | Enables direct thermal coupling to PCB copper; achieves 1.7 °C/W RθJC with 1 in² 2 oz Cu on FR-4. |
| Body-diode optimized | 183 ns trr and 2.1 µC Qrr reduce switching loss and EMI when used in quasi-resonant or active-clamp topologies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP6NK60ZFP | 600 V, 5.5 A, RDS(ON) = 1.2 Ω, Qg = 19 nC, TO-220FP package | Higher current rating but larger package and higher gate charge; requires more drive power and board space. | Preferred where higher continuous current (>3 A) and through-hole mounting are required; not drop-in due to different footprint and thermal path. |
| FQP6N60C | 600 V, 5.4 A, RDS(ON) = 1.3 Ω, Qg = 22 nC, TO-220 package | Higher ID and lower RDS(ON), but lacks 100% UIS test and has slower tr (25 ns) and higher Ciss (650 pF). | Acceptable for non-safety-critical consumer adapters where avalanche robustness is not mandated; requires layout review for EMI control. |
Compared with STP6NK60ZFP and FQP6N60C, the AOD2HC60 offers superior gate-charge efficiency (7.6 nC vs. ≥19 nC), smaller TO-252 footprint, and verified avalanche ruggedness-making it optimal for space-constrained, high-reliability 2–3 A offline switcher designs where thermal management and transient immunity are critical.

FAQ
What is the maximum continuous drain current rating for the AOD2HC60 at 100 °C case temperature?
The AOD2HC60 has a continuous drain current (ID) rating of 2.5 A at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This value reflects thermal derating from the 2.5 A rating at 25 °C case temperature and accounts for reduced channel conductivity and increased RDS(ON) at elevated temperatures. Designers must ensure heatsinking maintains TC ≤ 100 °C to sustain this current in continuous operation.
Does the AOD2HC60 support gate drive voltages below 10 V?
Yes-the AOD2HC60 has a gate threshold voltage (VGS(th)) of 3–5 V, so it begins conducting at VGS ≥ 4 V. However, full enhancement and guaranteed RDS(ON) ≤ 2 Ω require VGS = 10 V. Driving the AOD2HC60 at 5–8 V yields higher on-resistance and increased conduction loss; for optimal efficiency and thermal performance, the AOD2HC60 should be driven with a stable 10 V gate-source voltage.
Is the AOD2HC60 suitable for use in hard-switched PFC circuits?
No-the AOD2HC60 is not recommended for continuous hard-switched boost PFC stages due to its relatively high Coss (23 pF) and moderate switching speed (tf = 17 ns). Its design targets DCM/QR flyback and low-frequency (<150 kHz) switching applications. For PFC, devices with lower Qg/Coss ratios and faster turn-off (e.g., AOD2N60) are better suited; the AOD2HC60 may be used only in low-power, low-frequency auxiliary PFC or hold-up circuits.
What does "100% UIS Tested" mean for the AOD2HC60?
"100% UIS Tested" means every AOD2HC60 unit undergoes individual unclamped inductive switching stress testing per JEDEC JESD22-A109. Each device is subjected to L = 60 mH, IAS = 2.1 A, VDD = 150 V, RG = 10 Ω, starting at TJ = 25 °C, verifying single-pulse avalanche energy ≥132 mJ. This ensures field reliability under inductive turn-off faults-critical for AOD2HC60 deployment in flyback transformers and relay drivers.
Can the AOD2HC60 be mounted directly to a heatsink without isolation?
No-the AOD2HC60's drain is internally connected to the exposed metal pad on the TO-252 package bottom, making the drain electrically live. Direct mounting to a grounded heatsink creates a short circuit unless an electrically isolating thermal pad or insulating washer is used. For safe thermal management, mount the AOD2HC60 on a dedicated PCB copper pour tied to drain potential, or use isolating hardware if external heatsinking is required.
