Dual common-cathode switching diode in SOT-363
The Infineon BAV70SH6327XTSA1 is a dual common-cathode switching diode pair in a PG-SOT363-6-1 surface-mount package.
The 4 ns reverse recovery time is the spec that separates this diode from general-purpose rectifiers. In a snubber or flyback clamp across a switching node, a 4 ns trr means the diode turns off fast enough to avoid excessive ringing or power loss at moderate switching frequencies.
Last Buy — plan the BOM move now
Infineon has placed the BAV70SH6327XTSA1 in Last Buy status. That means the manufacturer's final production window is closing — once the last-time-buy period ends, this order code will no longer be manufactured. For a production BOM that currently specifies this part, the sourcing decision is to secure lifetime buy quantities or qualify a replacement before the window shuts.
Package and footprint notes for layout
The part comes in a PG-SOT363-6-1 package, also known as 6-VSSOP, SC-88, or SOT-363 — a 6-lead, 1.25 mm pitch, roughly 2.0 × 2.1 mm body. Surface-mount only. The common-cathode pinout (pins 2, 4, 5 tied to cathode; anodes on pins 1, 3, 6) is standard for the BAV70 series, so a layout drawn for any SOT-363 BAV70 variant accepts this device without a board change.
