Nijmegen -- Double space saving with integrated BJTs and resistors in ultra compact DFN2020(D)-6 packaging

Nexperia, the essential semiconductor expert, today 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 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 automotive (AEC-Q101 qualified) parts. The portfolio comprises more than 400 products, including both single and dual RETs with an expansive array of resistor combinations. Available in DFN and leaded SMD packages, Nexperia offers the optimal match for many applications.
