The BAS521BF is a high-voltage switching diode from Nexperia USA Inc., designed for high-speed switching applications. It is AEC-Q101 qualified for automotive use and comes in an ultra-small SOD523 (SC-79) surface-mount package.
Key electrical characteristics include a maximum reverse voltage of 200V (250V repetitive peak), forward current of 250mA, and a forward voltage of 1.25V at 200mA. The diode offers a fast reverse recovery time of 50ns, low leakage current of 100nA at 200V, and low diode capacitance of 2pF.
The device is suitable for high-speed switching, general-purpose switching, voltage clamping, and reverse polarity protection. It is mounted on an FR4 PCB with standard footprint for optimal thermal performance, with a maximum power dissipation of 250mW (standard footprint) or 380mW with a 1cm² cathode pad.
The SOD523 package is ultra-small and leadless, with dimensions 1.2mm x 0.8mm x 0.6mm body. The marking code is S2. The device is RoHS3 compliant and has an MSL of 1 (unlimited).
