AOD7B65M3

Overview

The AOD7B65M3 is a single N-channel IGBT from the AlphaIGBT™ series, manufactured by Alpha & Omega Semiconductor Inc. It features a maximum collector-emitter breakdown voltage of 650 V and a continuous collector current rating of 7 A at 25°C. The device is housed in a surface-mount TO-252 (DPAK) package with an exposed tab for thermal management. Key electrical parameters include a maximum collector-emitter saturation voltage of 1.9 V at 15 V gate drive and 7 A collector current. The total gate charge is specified as 14 nC, with turn-on and turn-off delay times of 10 ns and 85 ns respectively under standard test conditions. The component supports a junction temperature range from -55°C to 150°C and has a maximum power dissipation of 72 W.

Feature Summary

• Utilizes proprietary AlphaIGBT technology for optimized switching performance and low electromagnetic interference.
• Features a soft recovery integrated anti-parallel diode to minimize reverse recovery losses and voltage spikes.
• Designed with enhanced ruggedness for robust operation in high-frequency switching applications.

Applications

• High-frequency switch-mode power supplies (SMPS)
• Motor control inverters
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change based on production schedules and regional availability.

Selection Notes

Select this component for designs requiring a compact surface-mount IGBT with moderate current handling capabilities. Ensure the application's operating voltage remains below the 650 V breakdown limit and that the thermal design can dissipate up to 72 W. Verify that the gate drive circuitry provides the required 15 V swing to achieve the specified low saturation voltage and switching speeds.

Part Context

This part belongs to the AlphaIGBT™ family, which integrates fast-recovery diodes with IGBTs to simplify circuit design. The TO-252 package offers a balance between thermal performance and board space efficiency, making it suitable for dense PCB layouts in consumer and industrial electronics where through-hole packages are impractical.

Replacement Considerations

Direct replacements must match the 650V/7A rating and TO-252 footprint. Consider parts like the AOD6B65MQ1E for similar current ratings or the AOTF10B65MQ2 if higher current capacity is needed, provided the package type difference is accommodated in the design.

FAQ

What is the typical reverse recovery time of the integrated diode?

The integrated anti-parallel diode features a soft recovery characteristic with a reverse recovery time (trr) typically around 100 ns, which helps reduce switching losses and EMI.

Is the AOD7B65M3 available in a tube or reel package?

Standard distribution often utilizes tape-and-reel packaging for surface-mount assembly, but bulk tube options may be available depending on the distributor and order quantity; verify with the supplier.

What is the maximum operating junction temperature?

The device is rated for a maximum junction temperature (TJ) of 150°C, allowing for reliable operation in high-temperature environments within its specified power derating curve.
