Product details

Overview

AOK15B60D from Alpha & Omega Semiconductor is a 600 V, 15 A N-channel enhancement-mode MOSFET in TO-247 package, featuring 0.38 Ω typical R_DS(on) at V_GS = 10 V, 100% avalanche-rated operation, and optimized for high-efficiency switch-mode power supplies and PFC stages.

For engineers reviewing the AOK15B60D datasheet, pinout, applications, or equivalent options, key selection criteria include breakdown voltage rating, conduction loss at rated current, safe operating area under repetitive avalanche stress, and thermal resistance in TO-247 mounting configuration.

Technical Context

The AOK15B60D employs planar stripe gate structure with field-limiting rings to achieve stable 600 V blocking capability and low gate charge (Q_g = 42 nC typ). Its body diode exhibits 250 ns reverse recovery time (t_rr) and 30 A I_F peak rating, supporting hard-switched and ZVS topologies.

Designed for continuous conduction mode (CCM) PFC and LLC resonant converters, the device supports 175 °C maximum junction temperature, 1.25 Ω·cm² specific on-resistance, and meets JEDEC JESD47 reliability standards for industrial power applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Sustains full mains-line transients in universal-input 85–265 VAC systems without derating
I_D (T_C = 25°C)	15 A - Continuous drain current rating at heatsink-mounted condition, defining minimum heatsink sizing
R_DS(on) max	0.45 Ω - Maximum conduction loss at 10 V gate drive, directly impacts efficiency in 100–300 kHz PFC stages
E_AS	490 mJ - Single-pulse avalanche energy rating confirms robustness against inductive switching faults
R_θJC	0.85 °C/W - Junction-to-case thermal resistance enables direct thermal interface to heatsink without thermal pad compromise
Q_g	42 nC - Total gate charge determines driver strength requirement and switching loss trade-off

Pinout & Package

TO-247 package with three terminals: Drain (tab), Source (pin 1), Gate (pin 2). Mounting tab is electrically connected to Drain; requires insulated mounting hardware when referenced to non-Drain potentials.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current-carrying high-side terminal	Electrically tied to metal tab; primary heat path and high-voltage node in boost/buck circuits
Source (Pin 1)	Reference node for gate drive and current sensing	Low-impedance return path; used for shunt-based current feedback and gate driver reference
Gate (Pin 2)	Control electrode for channel formation	Requires 10 V min for full enhancement; sensitive to ESD; routed away from noisy power traces

Key Features

Feature	Design Value
100% UIS-tested avalanche capability	Guarantees single-pulse ruggedness up to 490 mJ without parameter shift or failure
Low Q_gd/Q_g ratio (0.22)	Reduces Miller-induced shoot-through risk in half-bridge configurations
Fast body diode t_rr = 250 ns	Minimizes reverse recovery losses in discontinuous conduction mode (DCM) flyback and LLC freewheeling
Enhancement-mode only (no threshold drift)	Eliminates need for negative gate bias; simplifies driver design in isolated gate-drive applications
RoHS-compliant, halogen-free construction	Meets IPC-J-STD-609A Class 1 definition for bromine/chlorine content in power semiconductors

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW15N60DM2	R_DS(on) = 0.35 Ω (lower), Q_g = 48 nC (higher), t_rr = 320 ns	Higher conduction efficiency but increased switching loss and slower body diode recovery	Preferred where conduction loss dominates (e.g., low-frequency PFC); less suitable for high-frequency ZVS designs
IXFH15N60P	R_DS(on) = 0.42 Ω, E_AS = 380 mJ, R_θJC = 1.0 °C/W	Lower avalanche ruggedness and higher thermal resistance limit peak power handling	Acceptable for non-avalanche-critical applications with conservative layout and thermal margin

Compared with STW15N60DM2 and IXFH15N60P, the AOK15B60D delivers balanced trade-offs: lower Q_g than ST's part improves switching efficiency, while higher E_AS and lower R_θJC than IXYS' part support more demanding transient and thermal conditions in compact industrial power modules.

FAQ

What is the maximum recommended gate-source voltage for AOK15B60D?

The AOK15B60D specifies ±25 V absolute maximum gate-source voltage (V_GS). Operation above +20 V or below –20 V risks permanent gate oxide damage. For reliable enhancement, AOK15B60D requires 10 V minimum V_GS to achieve rated R_DS(on); 12–15 V is typical for robust noise immunity in industrial SMPS layouts.

Does AOK15B60D require a negative gate turn-off voltage?

No, AOK15B60D does not require negative gate turn-off voltage. As an enhancement-mode MOSFET, it fully turns off at V_GS = 0 V. Negative gate bias is unnecessary and may accelerate gate oxide degradation. AOK15B60D's threshold voltage range (2.0–4.0 V) ensures clean turn-off with zero-gate-drive in standard gate driver configurations.

Can AOK15B60D be used in parallel configurations?

Yes, AOK15B60D supports paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing. Successful implementation requires matched gate drive loop inductance, symmetrical PCB layout, and individual gate resistors (≥10 Ω) to damp oscillation. AOK15B60D's low Q_gd/Q_g ratio further enhances dynamic current balance during switching transitions.

What is the thermal resistance from junction to case (R_θJC) for AOK15B60D?

The AOK15B60D has a maximum junction-to-case thermal resistance (R_θJC) of 0.85 °C/W, measured per JEDEC JESD51-14 with standard TO-247 mounting pressure (25–35 psi) and thermal interface material (TIM) conductivity ≥1.5 W/m·K. This value defines the upper bound of thermal impedance between die and heatsink surface in AOK15B60D-based designs.

Is AOK15B60D suitable for use in automotive-grade power supplies?

AOK15B60D is qualified to AEC-Q101 for discrete MOSFETs and operates over –55 °C to +175 °C junction temperature. While not automotive-qualified as a complete module, AOK15B60D meets critical stress-test requirements for under-hood DC-DC converters and onboard chargers. System-level qualification remains necessary, but AOK15B60D's 600 V rating and 490 mJ E_AS provide foundational ruggedness for automotive power applications.
