The Nexperia BAS21QB-QZ is a high voltage switching diode designed for fast switching applications. It features a single diode configuration in an ultra-compact DFN1110D-3 leadless surface mounted plastic package with side-wettable flanks. This package style facilitates efficient automatic optical inspection for reliability in manufacturing.
Rated for a maximum forward current of 250 mA and a maximum reverse repetitive voltage of 200 V, this diode provides excellent performance in high voltage environments. The device supports low leakage currents and low capacitance of up to 5 pF, making it ideal for high-frequency switching circuits.
Its fast switching speed is characterized by a peak reverse recovery time of 50 ns, ensuring minimal switching losses. Additionally, the diode can withstand peak non-repetitive forward surge currents up to 4 A, providing robustness for transient conditions.
The BAS21QB-QZ meets rigorous automotive standards with AEC-Q101 qualification, supporting operation in automotive electrical systems. It operates reliably over a wide temperature range from -65°C to 150°C. Its maximum forward voltage drop is 1.25 V, making it efficient for power-sensitive applications.
Compact physical dimensions of 1 mm height, 0.95 mm length, and 0.5 mm width make it suitable for space-constrained designs. Typical applications include industrial, automotive, telecommunications, and consumer electronics where high voltage and fast switching diodes are required.
Encapsulated in a small DFN1110D-3 plastic surface mount package. High voltage rating up to 200 V with low forward voltage drop. Fast switching with 50 ns reverse recovery time. Compliance with automotive AEC-Q101 standard ensures reliability.
Wide operating temperature range from -65°C to 150°C. Explore more discrete semiconductor components and Switching Diodes on EnvMart for robust industrial and automotive applications.
