Product Description
The Nexperia BAS21QB-QZ is a high-voltage switching diode designed for surface mount applications offering excellent high-speed switching and reliable performance. Enclosed in a leadless DFN1110D-3 plastic package, the diode provides a compact footprint with a low profile of 0.5 mm, ideal for space-constrained industrial, automotive, and electronic systems.
It supports a maximum forward current of 250 mA and withstands peak repetitive reverse voltages of 200 V, with a forward voltage drop of up to 1.25 V for efficient switching operation. The diode features a peak reverse recovery time (trr) of 50 ns, enabling high-speed switching useful in power management circuits and signal processing.
Device robustness is ensured by its qualification to AEC-Q101 standards, making it recommended for automotive applications requiring stringent reliability and temperature tolerance up to 150°C. The low leakage current and low junction capacitance (Cd ≤ 5 pF) facilitate minimal power losses and improved circuit performance.
The compact DFN1110D-3 package includes side-wettable flanks to accommodate automated optical inspection (AOI) processes during PCB assembly, enhancing manufacturing yield and quality control.
This switching diode is ideal for use in electronic circuits requiring fast Switching Diodes such as power supplies, inverters, automotive electronic control units, and other semiconductor discrete applications.
The diode features a peak reverse recovery time trr of 50 ns. It has a maximum power dissipation of 745 mW. The device operates over a temperature range from -65°C to 150°C. The package is a surface mount leadless design with ultra-small dimensions of 0.95 mm length, 0.5 mm width, and 1 mm height.
It is qualified according to AEC-Q101 automotive standards, suitable for automotive and industrial applications. The diode has low leakage current and low capacitance of 5 pF. Its maximum forward voltage is 1.25 V. The device supports peak non-repetitive surge current up to 4 A.
Packaging includes side-wettable flanks for automatic optical inspection of solder joints.
For reliable switching diode performance in high voltage, surface mounted circuits, the BAS21QB-QZ by Nexperia meets demanding industrial and automotive performance requirements available at EnvMart.
