The SQJA37EP-T1_GE3 is a type of insulated gate bipolar transistor (IGBT), specifically a N-channel MOSFET with an integrated avalanche diode that is capable of handling a large amount of current. It belongs to the family of “Single” MOSFETs and FETs. This particular type of transistor is designed for specific applications, such as high peak pulse power and fast switching devices for AC and DC drives, inverters, induction heating, uninterruptible power supplies, lighting ballast and solenoid control applications.

This type of transistor includes a versatile feature called diode emulation mode (DEM). When set in DEM mode, the device automatically switches from the normally low on resistance of the MOSFET to the higher on and reliability characteristics of an avalanche diode. This feature makes the SQJA37EP-T1_GE3 an ideal component for devices that require peak power or high efficiency.

Additionally, the SQJA37EP-T1_GE3 has low total gate charge and low conduction losses due to its low on-state resistance. This makes it ideal for AC and DC motor applications requiring high efficiency and fast switching. Additionally, the device also features a dV/dt immunity level of 500 V/μs that protects against high dV/dt and di/dt effects during turn-on, making it suitable for switching applications with high inductive loads.

Due to its high surge capability, the device can handle large surge currents with minimal stress, improving product reliability and extending operational lifetime. This makes the SQJA37EP-T1_GE3 an excellent component for uninterruptible power supplies and solar panel applications.

The SQJA37EP-T1_GE3 works by using a phenomenon called “avalanche breakdown” to control current flow. In the transistor, a junction is formed between a P-type and N-type region. An electric field is applied to the junction which causes the increased current to build up in the junction until a voltage sufficient to break down the junction is achieved. The breakdown of the junction releases a burst of current that is used to control the transistor’s operation.

By applying the correct voltages and currents, it is possible to switch the transistor on and off. When the transistor is turned off, the voltage across the junction is reduced, thus shutting down the avalanche breakdown process. When the transistor is turned on, higher voltages are provided, causing an avalanche breakdown. This allows the transistor to regulate large current levels and provide fast switching.

The SQJA37EP-T1_GE3 is a powerful and versatile component that is an excellent choice for a wide range of applications. It offers high peak power, efficient switching and long-term reliability that make it suitable for a wide variety of industrial and consumer applications.
