BAS19;BAS20;BAS21 are general purpose diodes fabricated in planar technology, and encapsulated in a small SOT23 plastic SMD package. They have a switching speed of 50ns, a maximum continuous reverse voltage of 100V, a maximum repetitive peak reverse voltage of 120V and a maximum repetitive peak forward current of 625mA.
The Philips BAS19, BAS20 and BAS21 are general‑purpose switching diodes offered in a small SOT23 plastic SMD package. They are intended for surface‑mounted circuits and provide fast switching with a maximum speed of 50 ns.
Key specifications include continuous reverse voltages of 100 V (BAS19), 150 V (BAS20) and 200 V (BAS21), repetitive peak reverse voltages up to 250 V, a continuous forward current of 200 mA, and forward voltage drops of 1 V at 100 mA and 1.25 V at 200 mA. Thermal resistance values are 330 K/W (junction‑to‑tie‑point) and 500 K/W (junction‑to‑ambient).
