Nexperia High Voltage Switching Diode, Single, 250 mA, 3-Pin Surface Mount DFN1412D-3 200 V BAS21QC-QZ

The Nexperia BAS21QC-QZ high voltage switching diode is a single discrete switching diode designed for high reliability in demanding electronic applications. Packaged in an ultra small, leadless DFN1412D-3 surface mount device, it features a compact form factor with dimensions 1.4 mm length, 1.2 mm height, and 0.5 mm width, making it ideal for space-constrained circuit boards.

With a maximum forward current of 250 mA and a maximum peak reverse voltage of 200 V, this diode is suitable for switching applications requiring robust voltage handling. Its fast reverse recovery time of 50 ns minimizes switching losses and improves efficiency in high frequency circuits.

The diode supports a power dissipation of up to 750 mW, ensuring stable operation under moderate load conditions. Low leakage current and low junction capacitance (≤5 pF) contribute to improved signal integrity and reduced noise in sensitive electronic circuits.

Qualified to the automotive standard AEC-Q101, the BAS21QC-QZ diode is recommended for automotive and industrial electronic systems that require stringent quality and reliability standards.

The diode operates reliably across a wide temperature range from -65°C to +150°C, ensuring performance in harsh environments. Its low profile package (height 0.5 mm) and side-wettable flanks enable automatic optical inspection (AOI) to assure solder joint quality during manufacturing.

Encapsulated in an ultra small leadless plastic DFN1412D-3 package for surface mounting. High switching speed with peak reverse recovery time ≤50 ns. High voltage capability with a maximum peak reverse repetitive voltage of 200 V.
