Global power management leader, International Rectifier (IR), has launched two new 40V automotive COOLiRFETâ„¢ MOSFETs: AUIRFN8459 and AUIRFN8458. These devices are designed for compact, high-current automotive applications such as motor control and body electronics, offering optimized on-resistance (Rds(on)) performance.
The AUIRFN8459 and AUIRFN8458 are the first two members of IR’s 5x6mm dual PQFN power MOSFET family using its advanced COOLiRFET™ 40V technology. The AUIRFN8459 delivers an ultra-low on-resistance of 5.9mΩ per channel and can handle up to 50A, setting a new benchmark in performance for automotive applications.
Pan Dawei, Vice President of Sales for IR Asia Pacific, stated: "Compared to traditional DPAK (TO-252) packages, the AUIRFN8459 and AUIRFN8458 40V 5x6mm dual PQFN COOLiRFETâ„¢ devices are more than 50% smaller. With ultra-low package resistance, inductance, and on-resistance, they are ideal for high-efficiency, high-power-density 12V automotive systems like motor control."
When compared to SO-8 packages, the new 5x6mm dual PQFN COOLiRFETâ„¢ devices offer a lower thermal path to the board, better thermal performance, higher efficiency, and improved power density, along with reduced system costs.
All IR automotive MOSFET products adhere to the zero-defect quality concept required by IR. They undergo dynamic and static device averaging, as well as 100% automated wafer-level visual inspection. The AEC-Q101 standard mandates that the on-resistance variation must not exceed 20% after 1,000 temperature cycle tests.
The new devices meet AEC-Q101 standards, are environmentally friendly, lead-free, and RoHS compliant.

An Indoor Access Point is a device for wireless local area networks (WLAN) that provides wireless network coverage and connectivity. It can connect to a wired network and transmit data via a wireless signal, allowing users to connect to the network wirelessly within coverage.
Indoor access points come in a variety of different types and specifications to suit different scenarios and needs. Here are some common types of indoor access points:
1. Single Band Access Point: A single band access point operates in the 2.4GHz band and typically provides a maximum transfer rate of 300Mbps. This type of access point is suitable for small office or home networks because the 2.4GHz band has better penetration and coverage, but a relatively low transfer rate.
2. Dual Band Access Point: The dual band access point supports both 2.4GHz and 5GHz bands, providing higher transmission rates and better performance. The 5GHz band has more interference free channels than the 2.4GHz band, which can provide faster speeds and more stable connections. Dual-frequency access points are suitable for medium sized offices, malls or hotels.
3. Lightweight Access Point: A lightweight access point is a wireless network device that needs to be used with a network controller. Lightweight access points do not have independent management functions themselves, but are centrally managed and configured via a network controller. This type of access point is suitable for large enterprises or organizations to enable centralized management and monitoring of the entire network.
4. Standalone Access Point: A standalone access point is a standalone device that has its own management and configuration functions and does not require additional network controllers. This type of access point is suitable for small businesses or individual users and can provide a simple and easy-to-use wireless networking solution.
5. Scalable Access Point: A scalable access point is a device that can scale on demand, increasing or decreasing the number of access points based on network demand. This type of access point is suitable for places that require flexible scaling, such as large office buildings, schools, or hospitals.
In addition to the types listed above, there are some special purpose indoor access points, such as:
1. Wall-mounted Access Point: A wall-mounted access point can be plugged directly into a Wall power outlet without the need for an additional power cord. This type of access point is suitable for home networks or small offices and can provide easy installation and use.
2. Integrated Antenna Access Point: The antenna of the antenna access point is integrated into the device, and no additional antenna installation is required. This type of access point is suitable for sites that require simple installation and a nice look.
3. Multiple Antenna Access Point: Multiple antenna access points can achieve better signal coverage and performance through multiple antennas. This type of access point is suitable for large venues or high-density user environments, such as conference rooms, stadiums or airports.
To sum up, there are many different types and specifications of indoor access points, which can be selected according to different scenarios and needs. Whether it's a small office, home network or a large enterprise, you can achieve convenient wireless network coverage and connectivity through indoor access points.
