Dual 500 mA RETs from Nexperia enable high-power load switching in space constrained applications Double space saving with integrated BJTs and resistors in ultra compact DFN2020(D)-6 packaging Nexperia, the essential semiconductor expert, released a new series of 500 mA dual resistor equipped transistors (RET) in ultra-compact DFN2020(D)-6 packaging. These devices have been 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. Notably, the RET in DFN configuration achieves dual space-saving feats. First, by ingeniously integrating the bipolar junction transistor (BJT) and resistor into a singular package, it offers substantial board space savings. Moreover, the leadless DFN packaging itself contributes to the spatial economy. This strategic confluence of integration and packaging underscores Nexperia’s dedication to meeting the compact spatial requisites that define contemporary electronic devices. To reduce component count and simplify board design, the twelve new RETs combine dual BJTs with bias resistors integrated in the same package. They also include a second integrated resistor parallel to the base-emitter path to create a voltage divider that sets the base voltage. This offers finer tuning and better turn-off characteristic behavior. Since these internal resistors have higher tolerances than external resistors, RETs are suitable for switching applications where transistors operate in an on- or off-state, helping to overcome the temperature dependence of standard BJTs. They also help to reduce the costs associated with pick and place and manual handling. RET devices in this series are available in a choice of dual NPN/NPN, NPN/PNP and PNP/PNP options. Unlike similar competing devices, Nexperia’s RETs fully deliver their specified 500 mA output current from a tiny DFN2020(D)-6 package measuring only 2 mm x 2 mm x 0.65 mm. This packaging is specialized for excellent thermal performance in high-power applications, delivering up to 1 W total output power from collector-emitter voltages (VCEO, open base) up to 50 V. Nexperia’s RET devices are available as standard and

New Compact VCSEL Proximity Sensor Contributes to Greater Miniaturization and Battery Capacity in Wireless Earbuds and other Wearable Devices ROHM has developed a compact 2.0mm × 1.0mm proximity sensor, the RPR-0720, optimized for applications requiring attachment/detachment and proximity detection. As the use of IoT continues to grow, sensor devices that play a critical role are requiring greater miniaturization and functionality. ROHM offers a lineup of proximity sensors that combine light emitting and receiving elements in a single package, providing unmatched versatility that has led to widespread adoption in a range of applications, from mobile devices to industrial equipment. Particularly for wearable devices, in response to the growing demand for small proximity sensors that can support improved designs and an increase in the number of parts resulting from higher functionality, ROHM developed a compact proximity sensor that integrates a VCSEL and sensor IC. The RPR-0720 is an optical sensor module that adopts a VCSEL featuring higher directivity than LEDs as the light emitting element and a sensor IC for the light receiving element. Compact size is achieved by optimizing the module structure using in-house chips, reducing area by approximately 78% compared to conventional products. At the same time, the wide input voltage range (2.7V to 4.5V) of the built-in VCSEL eliminates the need for
