What the BAS21 does
The BAS21x family comprises fast switching diodes available in BAS21 and BAS21S variants, housed in SOT-23 packages. These components handle a maximum repetitive peak reverse voltage of 250 V and dissipate 225 mW of power. They feature a reverse recovery time under 50 ns, a forward current rating of 0.2 Ampere, and a non-repetitive peak forward surge current of 2.5 A. Designed for general purpose switching applications, these diodes meet MSL level 1 standards and operate across a storage temperature range of -55 to +150 degrees Celsius.
