First, let’s take a look at TOLL packaging:
TOLL packaging is a package type characterized by a small footprint, low package resistance, and low parasitic inductance, commonly used for MOSFETs.
The advantages of TOLL packaging include a small footprint and low package inductance. Its features—including high current‑carrying capability, low parasitic inductance, and low thermal resistance—make it ideally suited for applications demanding high power, high current, and exceptional reliability.
TOLL‑packaged MOSFET products are already widely used by end‑customers in applications such as electric bicycles, electric motorcycles, lithium‑battery protection circuits, and communication power supplies. For example, the TOLL‑package power MOSFET series can handle peak currents exceeding 300 A and is primarily employed in high‑current scenarios like traction‑type BMS systems, inverters for energy storage, low‑speed electric vehicles, power tools, ESCs for drones, and propulsion motors for submersibles.
TOLL packaging also offers advantages such as higher efficiency, lower system costs, fewer parallel connections and reduced cooling requirements, as well as superior EMI performance.
TOLL packaging is a MOSFET package type with broad application prospects, well-suited for high-power, high-current, and high-reliability applications.
Characteristics of TOLL-packaged MOSFETs
TOLL-packaged MOSFETs are a commonly used packaging method, characterized by the following features:
- High‑integration TOLL‑packaged MOSFETs employ ultra‑small‑size chips during manufacturing, resulting in a high level of integration and enabling more functions to be implemented within a limited footprint.
- Low-power TOLL‑packaged MOSFETs feature low power consumption, effectively extending battery life and increasing device operating time.
- High Reliability: Thanks to the use of high-quality materials and stringent manufacturing processes, TOLL‑packaged MOSFETs exhibit exceptional reliability and can operate reliably even under harsh environmental conditions.
- TOLL‑packaged MOSFETs are widely used in mobile phones, tablet computers, video games, automotive electronic control systems, and other fields, where they deliver significant application value.
Precautions for Using TOLL‑Package MOSFETs
When using a MOSFET in a TOLL package, the following points should be noted:
- Electrostatic Protection: Due to the electrostatic sensitivity of MOSFETs in TOLL packages, electrostatic protection measures must be implemented prior to use to prevent damage to the components.
- Thermal performance: TOLL‑packaged MOSFETs have relatively high thermal requirements, so careful thermal‑management design is essential to ensure proper operation of the device.
- During the soldering of TOLL‑package MOSFETs, the soldering temperature must be carefully controlled to prevent component damage caused by excessive heat.
- MOSFETs packaged in TOLL must be stored under low‑temperature, dry conditions free of corrosive gases to prevent quality issues.
- Package specifications: Select the appropriate TOLL‑package MOSFET based on the specific application requirements to ensure compatibility with the required electrical performance and dimensions.

Advantages and disadvantages of the TOLL package compared to the TO-263 package:
- Compared to the TO-263-2L package, the resistance is reduced by 75%, and the current capacity is doubled.
- Compared with the TO-263-2L package, the TOLL package reduces PCB footprint by 30%, lowers height by 50%, and decreases board space by 60%, making it better suited for high‑power‑density applications.
- Compared with the TO-263-2L package, the TOLL package increases the source‑terminal solder contact area by a factor of four, thereby reducing current density and mitigating electromigration under high‑current and elevated‑temperature conditions. This enhances reliability, while its superior thermal performance delivers excellent temperature‑rise characteristics, further improving product reliability.
Low package resistance and parasitic inductance result in lower on‑resistance, higher peak current capability, and excellent EMI performance. This enables a reduction in the number of parallel MOSFETs in high‑power applications and enhances power density.
