Introduction: AOTF15B60D2 is a single IGBT from Infineon Technologies. It is a high performance IGBT with a maximum blocking voltage of 1200V, a high current rating of 15A and a very low on-state voltage drop of 1.6V at 10A. It is suitable for applications such as motor controls, inverters, lighting, commercial HVAC, high voltage DC and home appliances.

Application Field: AOTF15B60D2 is suitable for high power switching and control applications with high load currents, high switching/commutation frequency, high junction temperatures as well as complex gate drive requirements. It is used in brushless DC and AC motor drives, switched-mode power supplies, renewable energy applications, telecoms and audio power amplifiers.

Working Principle: AOTF15B60D2 works by controlling the current through the MOSFET array using a gate drive. The gate drive is essentially (SPWM) signal which acts as a switch to rapidly gate the IGBT in or out. The signal voltage is then used to turn the device on or off. This signal is called a Gate Voltage and is also referred to as a “Gate Drive”. When this voltage is above a certain threshold (5V for AOTF15B60D2), the IGBT turns on and current flows through it. Conversely, when the gate voltage falls below a certain threshold (1.5V for AOTF15B60D2), the IGBT turns off and no current flows through it.

Switching Performance: AOTF15B60D2 has a fast turn-on and turn-off times; typical turn-on times are in the range of 5us- 10us, while the turn-off times are in the range of 3us- 8us. This fast switching performance translates into higher energy efficiency of the devices and makes them ideal for use in high power switching applications.

Thermal Performance: AOTF15B60D2 features an integrated heat sensing circuit which allows for thermal protection of the device. This helps to maximize the device’s operation in a range of environmental conditions and ensures it will not overheat or otherwise fail due to excessive current or temperature.

Conclusion: AOTF15B60D2 is a single IGBT from Infineon Technologies. It is suitable for applications such as motor controls, inverters, lighting, commercial HVAC, high voltage DC and home appliances. It works using a gate drive circuit which turns it on or off, depending on the signal voltage applied. Additionally, the device has a fast switching response and a thermal sensing circuit which allows it to be used in a variety of demanding applications.
