The application circuit of the 72V electric vehicle controller includes motor drive circuit, power conversion circuit, and protection circuit, all three of which require the use of MOSFETs. How do we choose a replacement for the IRFB4410 MOSFET model in the 72V electric vehicle controller? What factors should be considered?

Generally speaking, when selecting a MOSFET for a 72V electric vehicle controller, we focus on the MOSFET's voltage endurance, circuit design, on-resistance, switching speed, and packaging.

Engineers familiar with the parameters of the IRFB4410 field-effect transistor know about this product. Today, I will introduce another domestic MOSFET that is very suitable for 72V electric vehicle controllers: the FHP130N10A field-effect transistor.

Why is the FHP130N10A field-effect transistor very suitable for use in a 72V electric vehicle controller?

Reason one: The voltage of the FHP130N10A field-effect transistor is 100V. To ensure safety margin, the MOSFET's voltage endurance should be at least 1.5 times or more than the battery voltage. The maximum value of the battery voltage in a 72V electric vehicle generally exceeds 72V slightly, so choosing a 100V MOSFET is the best choice.

Reason two: Select an appropriate current specification based on the motor's peak current and system requirements. Generally, electric vehicle motors require high current switching, so it is important to pay attention to the MOSFET's continuous current and pulse current capability. The FHP130N10A field-effect transistor has a current rating of 130A, which is very suitable for high current applications.

Reason three: The FHP130N10A field-effect transistor has a TO-220 package form, which ensures good heat dissipation performance. It also features excellent on-state performance and fast switching speed.

In addition to meeting these three main reasons, the FHP130N10A also has 100% EAS testing, 100% Rg testing, 100% DVDS testing, high avalanche withstand capability, high reliability, low Qgd, and low RDSon characteristics.

Therefore, in the process of replacing domestic field-effect transistors, we recommend using the high-quality Feihong domestic model: the FHP130N10A instead of the IRFB4410 model.

This FHP130N10A from Feihong is an N-channel enhancement mode field-effect transistor. Besides being used as a dedicated MOSFET for 72V electric vehicle controllers, it is also widely applied in various DC motor drives, 24V input inverters, UPS systems, etc.

Replacing a 100V, 130A MOSFET is crucial to select the right model. Feihong Semiconductor's MOSFETs are already widely used in power circuits, smart home appliances, new energy electronics sectors: such as automotive electronics, electric scooters, smart speakers, household appliances, LED lighting, chargers, computer power supplies, and other industries, providing quality products and services to domestic electronic product manufacturers.
