Blog Article
TOLL (Transistor Outline Leadless) package is an advanced SMD package, which features a pinless design and a package size of only 9.90 mm × 11.68 mm × 2.3 mm (L × W × H), which greatly reduces the package size, reduces the PCB board area and height, and its compact size and optimized heat dissipation path improve heat dissipation efficiency, improve electromagnetic interference (EMI) and reduce parasitic inductance and package resistance. It is very suitable for high power density applications and has been widely used in high current and high power density application scenarios such as two-wheeled vehicles, electric vehicles, lithium battery formation equipment, drones, photovoltaics, energy storage, etc.
1. Advantages of TOLL package
1. Small size
TOLL package is known for its compact size. Compared with traditional packaging methods (such as TO-263-3L/7L), TOLL package PCB board area is reduced by 30%, height is reduced by 50%, and circuit board space is reduced by 60%. This small volume design is very suitable for high power density applications.
2. Low package resistance and parasitic inductance
TOLL package has low package resistance and parasitic inductance, which brings smaller on-resistance, higher peak current and stronger EMI (electromagnetic interference) suppression capability. It can reduce the number of parallel MOSFETs in high-power applications, increase power density, and thus reduce production costs.
3. Excellent heat dissipation performance
TOLL package has excellent heat dissipation performance. Its heat dissipation path is Junction → Case → Solder → PCB → VIAs → PCB → TIM → Heatsink. Although the path is relatively long, the heat dissipation efficiency is still very high. This helps to reduce device temperature rise and improve product reliability and life.
4. High current carrying capacity
Due to its unique packaging structure, TOLL package can carry higher current to meet the needs of high-power applications.
2. TOLL package market application
1. Two-wheeled vehicles, electric vehicles
TOLL package MOSFET is widely used in the power control system of two-wheeled vehicles and electric vehicles. Its high current carrying capacity and low on-resistance help improve the power performance and efficiency of the vehicle. In the lithium battery protection BMS system, TOLL packaged MOSFET is used to control the battery charging and discharging process and protect the battery from damage such as overcharging and over-discharging. Its low parasitic inductance and high thermal performance ensure the safe and stable operation of the battery system.
2. Lithium battery formation
Under the national dual-carbon policy, the new energy market is booming, and the demand for lithium batteries has skyrocketed, and it has become an upward trend year by year. The formation and capacity division equipment have high requirements for the measurement accuracy of current and voltage. The DC-DC module focuses on meeting customers' functional requirements for lithium battery charging and discharging. The low loss, high efficiency and reliable characteristics of TOLL packaged MOSFET help improve system efficiency and stability and measurement accuracy.
3. UAV
With the increasing maturity of drone technology, drones are increasingly used in industry, agriculture, national defense and other fields. TOLL packaged MOSFET has extremely low internal resistance and excellent switching speed. During the operation of the drone, it can respond quickly to various commands and achieve precise control. At the same time, the low internal resistance characteristics also ensure that the drone has higher power efficiency and longer battery life during flight. In extreme environments, such as high temperature, high humidity, and high altitude, it can still maintain stable performance, ensuring that drones can work normally in various complex environments.
4. Photovoltaic energy storage system
Today, the new energy market is becoming more and more popular. In applications such as photovoltaic system MPPT, inverter and DCDC conversion, in energy storage system PCS, BMS, DC-DC conversion and other applications, the requirements for power devices in all aspects will be higher in the future. The advantages of TOLL packaged MOS can better meet the requirements of various application scenarios.
