BAS19; BAS20; BAS21 are three general purpose diodes from NXP, packaged in SOT23 with a high switching speed, maximum reverse voltage of 100 V, 150 V, 200 V, and maximum forward current of 625 mA.
The BAS19, BAS20 and BAS21 are general‑purpose switching diodes offered in a small SOT‑23 surface‑mount package. They are intended for use in a variety of circuits where fast switching and moderate voltage ratings are required.
The datasheet lists key specifications such as a maximum switching speed of 50 ns, continuous reverse voltage ratings of 100 V (BAS19), 150 V (BAS20) and 200 V (BAS21), and a repetitive peak forward current of 625 mA. Thermal resistance values, diode capacitance, and detailed graphical data are also provided.
