Let’s zoom in on the scope:

• A hint of ringing
• A tiny gate dip
• UVLO triggers

Then silence again. It’s rarely the driver. Usually, it’s the diode no one thinks about:

The one that charges the bootstrap capacitor a thousand times a second. At high dv/dt that diode becomes a noise source.

A little capacitance here, a little charge there and suddenly your “stable” design isn’t.

We built the SI02C120SMB to end that.

A 2 A / 1200 V SiC Schottky in an SMB package.

• Low junction capacitance.
• Almost zero recovery charge.
• No bootstrap resistor needed.
• No EMI ghosts in your gate signal

It just works - fast, clean, and repeatable.

In power design, stability isn’t loud. It’s the silence that tells you it’s right.
