Nexperia enhances Zener diode portfolio
Nexperia has announced two enhancements to its Zener diode portfolio that both eliminate undesirable overswing and noise behaviour.
First, the new 50 µA-Zener series with B-selection (Vz +/-2 percent) and Vz ranging from 1.8 V to 51 V is offered in standard and automotive qualified variants. This makes them suitable for automotive applications like on-board chargers in EVs as well as for a broad range of industrial and consumer applications like general-purpose computing units, battery management systems, device chargers and smartwatches.
These devices now deliver full Zener functionality even at high voltages (up to 75 V). They have also been designed to entirely eliminate the noise and overswing phenomena, common features of many Zener diodes that have previously led to application failures.
The devices are available in SOT23, SOD323, SOD523, and SOD123F as well as DFN1006BD-2 and DFN1006-2 with or without side-wettable flanks (SWF). The inclusion of SWF offers significant advantages, including highly reliable automated optical inspection (AOI) of solder joint quality and increased robustness of solder joints, enhancing the bond to the PCB compared to devices without SWF.
Nexperia is also addressing overswing and noise concerns in its existing family of general-purpose PZU Zeners, providing engineers with greater flexibility for applications like supply voltage stabilisation, comparison of sensor or supply voltages in addition to providing gate and avalanche breakdown protection for MOSFETs.
The PZU family is available in SOD323, SOD323F, SOT23, DFN1006BD-2 and DFN1006-2 (2.4 V-51 V) packages, in both automotive and standard versions. Offering designers a viable alternative for critical applications that demand a sharper Zener ‘knee’, or where standard Zeners may show noise and overswing behaviour.
