A double space saving is provided with the 500mA resistor equipped transistors (RETs) said Nexperia. They integrate bipolar junction transistors and resistors in a single package to enable high-power load switching in space constrained applications.
The 12 RETs are in compact DFN2020(D)-6 packaging and designed for load switching in wearables and smartphones as well as for use in digital circuits with higher power requirements, such as space constrained computing, communications, industrial and automotive applications.
The RET in DFN configuration achieves dual space-saving feats, said Nexperia. Firstly, integrating the bipolar junction transistor (BJT) and resistor into a single package offers substantial board space savings and secondly, the leadless DFN packaging contributes to space savings.
The RETs deliver the specified 500mA output current from a tiny DFN2020(D)-6 package measuring only 2.0 x 2.0 x 0.65mm. This packaging is particularly suitable for thermal performance in high power applications, delivering up to 1W total output power from collector-emitter voltages (VCEO, open base) up to 50V.

STM32H5 discovery kit builds a case for secure, smart, connected devices
Support for Secure Manager, a turnkey SoC which integrates core security services certified and maintained by ST is included in the STM32H5 discovery kit by STMicroelectronics.
The development board is for creating diverse applications with the company’s STM32H5 microcontrollers. The STM32H5 devices are intended for high performance processing and advanced security in a wide range of applications, including smart sensors, smart appliances, industrial controllers, networking equipment, personal electronics and medical devices.
The STM32H573I-DK discovery kit enables developers to explore all the integrated features of the STM32H5, such as analogue peripherals, timers, the ST ART (Adaptive Real-Time) accelerator, media interfaces and mathematical accelerators. This makes it easy to evaluate new designs for industrial programmable logic controllers (PLC), motor drives, and smart controllers for appliances, for example, air conditioners, refrigerators and washing machines. Other potential applications include alarm controllers, communication hubs and smart lighting controls.
The STM32H573I-DK Discovery kit is a development board that includes an STM32H5 microcontroller, colour touch display, digital microphone, and interfaces such as USB, Ethernet, and Wi-Fi. The board also features an audio codec, flash memory, and headers for connecting expansion shields and daughterboards.
To simplify the development process, the STM32CubeH5 microcontroller software package consolidates all the necessary components required to develop an application on the STM32H5, including examples and application code. The package is fully integrated into the STM32Cube ecosystem, which contains additional software to assist with application development. ST also offers the STM32CubeMX tool for configuring and initialising the microcontroller.
The STM32H5 microcontroller features the Arm Cortex-M33 embedded microcontroller core running at 250MHz and is the first microcontroller to support ST’s Secure Manager SoC security solutions. The microcontrollers combine Arm TrustZone security with ST’s STM32Trust framework to provide trusted storage, cryptography, attestation and updates. They embed side-channel protected hardware cryptographic accelerators and target recognised security certifications, PSA Certified Level 3 and GlobalPlatform SESIP3.
ST has created the STM32H573I-DK Discovery kit with examples showing how to use the security services and integrated all the necessary software tools and support in the STM32Cube development ecosystem.
The Discovery kit as well as the H5 Nucleo Board Nucleo-H563ZI are available now available from ST’s eStore and authorised distributors.
