The Diotec Semiconductor BAV20WS is a surface-mount small signal switching diode housed in an SOD-323F package. It features a maximum repetitive peak reverse voltage of 200 V and a DC reverse voltage of 150 V. The device supports a maximum average forward current of 200 mA with a non-repetitive peak forward surge current of 2.5 A. Forward voltage remains below 1 V at 100 mA and below 1.25 V at 200 mA. Reverse leakage current is less than 100 nA, while junction capacitance is under 5 pF. The component operates within a junction temperature range up to +150°C.
Verify the specific ordering suffix when purchasing. Standard commercial/industrial grade parts have no special suffix. Automotive-grade variants require specific suffixes: -Q indicates AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm these designations match project requirements before procurement.
Select this component for circuits requiring fast switching speeds and low parasitic capacitance. Ensure the 200 mA average forward current rating meets load demands. Verify thermal management capabilities, as power dissipation is rated at 200 mW on a PCB with 3 mm² copper pads per terminal. Consider automotive grades if operating in vehicle environments.
This part belongs to the BAV19WS through BAV21WS series of SMD small signal switching diodes. All models share identical mechanical data and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings. The BAV20WS specifically bridges the gap between the 120 V BAV19WS and the 250 V BAV21WS.
BAV19WS (120 V), BAV21WS (250 V). Automotive equivalents include BAV19WS-AQ, BAV20WS-AQ, and BAV21WS-AQ.
