Last Buy — plan the BOM move now
Infineon has marked the BAV70WH6327XTSA1 as Last Buy. That means the official production window is closing — once the last-time-buy date passes, the only channel will be surplus or broker stock. If this dual common-cathode switching diode is on your BOM, qualify a replacement or secure your lifetime buy quantity now.
The 80 V reverse voltage (Vr max) and 200 mA average rectified current per diode (Io) set the operating headroom for low-power rectification and signal clamping. The 4 ns reverse recovery time (trr) is fast enough for high-frequency switching up into the tens of megahertz — think flyback snubbers, logic-level translation, or protection networks on data lines. Forward voltage is 1.25 V at 150 mA, typical for a small-signal silicon diode; the 150°C maximum junction temperature gives margin in warm environments.
PG-SOT323 package — rework and footprint
The part ships in a PG-SOT323 (SC-70) surface-mount package — three leads, compact body about 2.0 x 1.25 mm. The small thermal mass reflows easily with a standard hot-air profile; just watch the orientation mark (pin 1 identifier) before placement.
