Product details
Overview
AOKS40B65H2AL from Alpha & Omega Semiconductor is a 650V, 40A high-speed IGBT with 2.05V VCE(sat) at TJ=25°C, optimized for PFC circuits and high-frequency switching applications. It features low turn-off energy (0.54 mJ), soft switching behavior, and excellent EMI performance in TO-247 package.
For engineers reviewing the AOKS40B65H2AL datasheet, pinout, applications, or equivalent options, key selection criteria include VCE(sat), Eoff, switching speed (Td(off) = 117 ns), thermal resistance (RθJC = 0.48°C/W), and gate charge (Qg = 61 nC).
Technical Context
The AOKS40B65H2AL implements AlphaIGBT™ technology with controlled di/dt turn-on and soft turn-off characteristics to minimize voltage overshoot and EMI. Its dynamic parameters are characterized under inductive load conditions (VCC = 400–520 V, IC = 40 A, RG = 7.5 Ω) across junction temperatures from 25°C to 150°C.
Static operation is defined by VGE(th) = 4.7 V (typ), gFS = 24 S (typ), and tight VCE(sat) drift (2.71 V max at TJ = 150°C). The device supports ±30 V gate-emitter voltage and exhibits low leakage (IGES ≤ ±100 nA).

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN40N60B3 | VCE(sat) = 2.2 V (typ), Eoff = 0.72 mJ (25°C), RθJC = 0.55°C/W | Higher conduction and switching loss; less suitable for >120 kHz PFC | Preferred where legacy layout compatibility with IXYS footprint is required |
| Infineon IKW40N65ES5 | VCE(sat) = 1.7 V (typ), but Eoff = 1.05 mJ (25°C); higher Qg = 110 nC | Better conduction efficiency but slower switching and higher drive power demand | Selected when lower VCE(sat) dominates over switching loss in <100 kHz applications |
Compared with IXGN40N60B3 and IKW40N65ES5, the AOKS40B65H2AL delivers superior high-frequency trade-off: lowest Etotal (1.71 mJ) and fastest Td(off), making it optimal for digitally controlled, high-efficiency PFC where thermal and EMI constraints are tight.

FAQ
What is the maximum continuous collector current rating for AOKS40B65H2AL at case temperature of 100°C?
The AOKS40B65H2AL is rated for 40 A continuous collector current at TC = 100°C, as specified in its Absolute Maximum Ratings table. This rating assumes proper heatsinking and adherence to the SOA limits defined in the datasheet. Derating applies above 100°C case temperature per Figure 10.
Does AOKS40B65H2AL integrate an anti-parallel diode?
No, the AOKS40B65H2AL is a discrete IGBT without an integrated freewheeling diode. External diode selection-such as the AOK40B65H2AL referenced in the datasheet's Eon/Etotal test notes-is required for inductive switching applications. Diode reverse recovery characteristics directly impact total switching loss measurements.
What gate resistor value is recommended for AOKS40B65H2AL in a 100 kHz PFC design?
A gate resistor of 7.5 Ω is used in the datasheet's switching characterization (TJ = 25°C and 150°C), yielding Td(off) = 117 ns and Eoff = 0.54 mJ. For 100 kHz PFC, this value balances switching speed and gate drive loss; lower values increase dv/dt stress, higher values raise Eoff.
Is AOKS40B65H2AL suitable for use in 400 V DC bus applications?
Yes, the AOKS40B65H2AL has a 650 V VCES rating with sufficient margin for 400 V DC bus systems, including transient overvoltage conditions per IEC 61000-4-5. Its soft turn-off and low EMI behavior further enhance reliability in such applications without requiring additional snubbers.
What is the thermal resistance from junction to case (RθJC) for AOKS40B65H2AL?
The AOKS40B65H2AL has a maximum junction-to-case thermal resistance (RθJC) of 0.48°C/W, measured under standard test conditions. This value is critical for calculating junction temperature rise and verifying safe operation under given power dissipation and heatsink conditions.
