Product details
Overview
AOD4C60 from Alpha & Omega Semiconductor is a 600 V, 4 A N-channel enhancement-mode MOSFET in TO-252 (DPAK) package, featuring RDS(ON) < 0.95 Ω at VGS = 10 V, 14 nC typical gate charge, and 100% UIS-tested ruggedness-designed for primary-side switching in offline AC-DC power supplies.
For engineers reviewing the AOD4C60 datasheet, pinout, applications, or equivalent options, key selection criteria include avalanche energy rating (326 mJ), dv/dt ruggedness (100 V/ns), thermal resistance (RθJC = 1.0 °C/W), and body-diode recovery performance (Qrr = 3.6 µC, trr = 295 ns).
Technical Context
The AOD4C60 employs high-voltage trench-gate MOSFET process technology optimized for fast-switching, low-conduction-loss operation in discontinuous conduction mode (DCM) flyback and quasi-resonant (QR) converters. Its guaranteed unclamped inductive switching (UIS) capability supports robust overcurrent protection without external snubbers.
With Ciss = 910 pF, Crss = 1.8 pF, and low Qgd/Qgs ratio (2.9/5.5 nC), the AOD4C60 enables stable gate drive control and reduced Miller-induced turn-off delay in high-frequency SMPS designs up to 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V maximum - supports 400 VAC input with margin for surge and ringing in universal-input offline converters |
| RDS(ON) | < 0.95 Ω at VGS = 10 V - limits conduction loss to ≤15.2 W at 4 A continuous, enabling compact heatsinking |
| Qg | 14 nC typical - allows efficient 10 V gate drive with ≤1.4 W average gate power at 100 kHz switching |
| Eoss | 2.7 µJ at 400 V - reduces turn-on switching loss and eases ZVS implementation in resonant topologies |
| IDM | 27 A pulsed - sustains short-circuit events in current-mode controlled flyback without latch-up |
| TJ range | –50 °C to +150 °C - qualified for consumer-grade ambient operation with derating above 25 °C |
Pinout & Package
Package: TO-252 (DPAK), surface-mount, single-ended drain-source layout with exposed drain pad for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal; requires ≥10 V for full enhancement; 4.2 Ω internal gate resistance limits ringing |
| D | Drain | Main high-side power terminal; electrically connected to exposed copper pad for thermal path to PCB |
| S | Source | Reference node for gate drive and current sensing; tied to power ground in low-side configurations |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guarantees 326 mJ single-pulse avalanche energy (L = 60 mH, VDD = 150 V), eliminating need for external clamping in transient overload |
| Low Crss / Ciss ratio | Crss = 1.8 pF, Ciss = 910 pF → 0.2% feedback capacitance minimizes Miller effect and improves noise immunity |
| Body diode with fast recovery | trr = 295 ns, Qrr = 3.6 µC - reduces reverse-recovery loss and EMI in synchronous rectification or freewheeling paths |
| High dv/dt ruggedness | 100 V/ns rated - prevents false turn-on during high-slew-rate voltage transients in high-side switch applications |
Applications
| AC-DC Flyback Converter | QR/LLC Resonant PSU |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP4NK60ZFP | 600 V, 4 A, RDS(ON) = 1.2 Ω (typ), Qg = 12 nC, no UIS rating specified | Lacks guaranteed avalanche testing; lower gate charge but higher on-resistance increases conduction loss | Acceptable where surge immunity is managed externally and thermal margin permits higher RDS(ON) |
| FQP4N60 | 600 V, 4 A, RDS(ON) = 1.5 Ω (max), Qg = 16 nC, no UIS or dv/dt ruggedness data published | No published UIS or dv/dt specs; higher RDS(ON) demands larger heatsink at full load | Suitable only in non-critical, low-cost designs with ample thermal headroom and no line surge exposure |
Compared with STP4NK60ZFP and FQP4N60, the AOD4C60 delivers superior system-level reliability in AC-DC primary switches due to its guaranteed 326 mJ UIS rating, 100 V/ns dv/dt ruggedness, and tighter RDS(ON) distribution-reducing design margin overhead and qualification effort.

FAQ
What is the maximum continuous drain current rating for the AOD4C60 at 100 °C case temperature?
The AOD4C60 supports 3.5 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derated value reflects thermal limitations of the TO-252 package under sustained high-temperature operation and must be used for thermal design validation-not the 4 A rating at 25 °C. The AOD4C60 remains within safe SOA limits when operated within this boundary.
Does the AOD4C60 have a fully characterized body diode for synchronous rectification use?
The AOD4C60 features a fully specified body diode with VSD = 0.74–1.0 V at IS = 1 A and fast recovery parameters: trr = 295 ns and Qrr = 3.6 µC at IF = 4 A, dI/dt = 100 A/µs. While not optimized as a dedicated synchronous rectifier, these values support limited freewheeling or low-duty-cycle synchronous operation in flyback topologies-but discrete Schottky diodes remain preferred for high-efficiency secondary-side rectification.
Is the AOD4C60 pin-compatible with the AOI4C60?
No-the AOD4C60 uses TO-252 (DPAK) packaging with G–D–S pinout in top view, while the AOI4C60 uses TO-251 (IPAK) with identical pin assignment but different mechanical footprint and thermal pad layout. PCB layout and thermal interface must be redesigned when substituting between AOD4C60 and AOI4C60; they are functionally equivalent but not mechanically interchangeable.
What gate drive voltage is required to achieve the specified RDS(ON) for the AOD4C60?
The AOD4C60 achieves its specified RDS(ON) < 0.95 Ω at VGS = 10 V, with gate threshold voltage VGS(th) ranging from 3 V to 5 V. To ensure full enhancement and minimal conduction loss across temperature and unit variation, a minimum gate drive of 10 V is required. Driving below 8 V risks incomplete turn-on and excessive heating, especially at elevated junction temperatures.
Can the AOD4C60 be used in hard-switched PFC boost stages?
The AOD4C60 is not recommended for continuous hard-switched PFC boost applications due to its relatively high Coss (41 pF) and lack of optimized gate charge profile for high-frequency, high-dV/dt boost switching. Its design focus is on flyback and QR converters up to 100 kHz. For PFC, devices with lower Qg/Qgd, enhanced Eoss, and dedicated PFC qualification (e.g., AOD6B65) are preferred over the AOD4C60.
