BAS16 Equivalent Diode

BAS16 is a high-speed switching diode (usually SOT-23 package, the maximum withstand voltage of 100V, forward through the continuous current allowed to be 200mA), it has a low leakage current and fast recovery and other characteristics, so in high-frequency circuits are widely used (eg, Buck circuits), if you want to achieve the equivalent replacement of circuits need to focus on reverse recovery time (4ns level), the maximum withstand voltage and current parameters. If you want to achieve equivalent replacement in the circuit, you need to focus on the reverse recovery time (4ns level), maximum withstand voltage and current parameters.

Precautions for use:

In the welding process is extremely easy to bridge phenomenon (two pins welded together), it is recommended to use a thermostatic soldering station, the first 250 ° C pre-heating pad, and then increase the temperature to quickly spot weld pins. In the process of reflow soldering should pay attention to, the maximum temperature should not exceed 260 ° C, in order to prevent diode damage.
In high-frequency applications be aware of the parasitic inductance and junction capacitance, which can form resonances (LC oscillations, which we will need in some circuits, depending on the application of the circuit) and thus generate noise. For example, in BUCK circuits, when synchronous rectification is implemented in BAS16, RC buffer circuits need to be placed to suppress this phenomenon, but at the same time the switching efficiency will be slightly reduced.
Example: D in the figure below is the continuity diode, when the switching MOS on, the continuity diode cut-off; when the switching MOS cut-off, the continuity diode on; in the fast switching in the continuity diode resonance, so you need a RC buffer circuit to suppress.
