Onsemi BS170’s Category - MOSFETs
MOSFET (Metal - Oxide - Semiconductor Field - Effect Transistor) is a semiconductor device widely used for switching purposes and the amplification of electronic signals in electronic devices. Due to the very small size of MOSFETs, they can be either the core or an integrated circuit and can be designed and manufactured in a single chip. The introduction of MOSFET devices has brought changes to the field of electronic switching.
Types of MOSFETs
The mainstream MOSFETs are mainly divided into four categories: planar power MOSFETs, trench power MOSFETs, super - junction power MOSFETs, and shielded - gate power MOSFETs (SGT).
(1) Planar power MOSFETs: They emerged in the 1970s. They are easy to drive and have a high operating frequency, but the chip area is relatively large and the losses are high.
(2) Trench power MOSFETs: They came out in the 1980s. They are easy to drive, have a high operating frequency, good thermal stability, and low losses, but the voltage resistance is low.
(3) Super - junction power MOSFETs: They appeared in the 1990s. They are easy to drive, have an ultra - high frequency, and extremely low losses. They are the latest generation of power devices.
(4) Shielded - gate power MOSFETs (SGT): They emerged in the 21st century. They break the silicon limit and greatly reduce the on - resistance and switching losses of the devices.
Common Applications of MOSFETs
(1) One of the main application areas: Charging piles
Charging piles are listed as one of the seven "new infrastructure" fields in China. Public charging piles are set up by institutions with public - service nature such as government agencies, and the service objects are all electric vehicle owners. From 2015 to 2019, the number of public charging piles in China increased from 58,000 to 516,000, with a compound annual growth rate of 72.9%.
(2) One of the main application areas: 5G base stations
Regarding the construction scale of 5G base stations, at the 2021 China Academy of Information and Communications Technology (CAICT) ICT + In - depth Observation Report Conference on December 15, 2020, a spokesperson from the Ministry of Industry and Information Technology pointed out that China has cumulatively built 718,000 5G base stations and promoted the co - construction and sharing of 330,000 5G base stations.
(3) One of the main application areas: Automotive - grade applications
To achieve energy conversion and transmission, new components such as motor control systems, DC/DC modules, high - voltage auxiliary drives, on - board charging systems (OBC), and power management ICs have been added to new energy vehicles, and the content of power semiconductors in them has greatly increased. In terms of semiconductor types, automotive semiconductors can be roughly divided into power semiconductors (such as IGBTs and MOSFETs), MCUs, sensors, and other components.
