It comes in a standard SOT-23-3 surface-mount package (PG-SOT23) and is supplied on tape and reel. The 100 ps reverse recovery time makes it suited for high-speed clamping, flyback catch, and low-voltage OR-ing applications where signal integrity matters. This part carries an obsolete lifecycle status. That means Infineon has ended production; no last-time-buy window remains. Any units you source will come from surplus or broker inventory. For a production BOM, you will need to qualify a replacement — either a same-package Schottky dual common-anode diode or a redesign if the footprint changes. ## 70 V, 70 mA, 100 ps — the envelope The 70 V reverse voltage covers low-voltage rails up to 48 V with margin. The 70 mA average current per diode handles small-signal loads — think I²C bus protection, relay coil catch, or logic-level level shifting. Forward drop is 1 V at 15 mA, typical for a small-signal Schottky. The 100 ps trr is fast enough for MHz-range switching edges without adding recovery loss. ## Common anode — orientation matters The common-anode configuration means the two cathodes are independent; the anodes are tied together internally. That is the opposite of a common-cathode dual diode. If your circuit expects the cathodes common, this part will not work — check the schematic before ordering. The SOT-23-3 package is pin-compatible with many small-signal dual Schottkys, but the internal wiring is not universal. ## Sourcing reality We source it through our independent supply network — each quote is confirmed against available surplus inventory at the time of your RFQ. Availability and pricing vary; we do not carry stock on the shelf for this line.
