Dual common-cathode diode in a small outline package
It is housed in the SC-70 (SOT-323) surface-mount package, a compact 3-pin outline with 0.65 mm lead pitch. The 4 ns reverse recovery time qualifies it for high-frequency switching tasks — rectification, clamping, and logic-level shifting in circuits up to several MHz. The common-cathode pair is useful for full-wave rectification or as a steering diode pair in redundant supply OR-ing circuits.
That means the manufacturer has announced end-of-life and is accepting final orders only during a defined last-time-buy window. Once that window closes, the part will no longer be manufactured. For a BOM line using this diode, the procurement action is clear: either place a lifetime buy to cover forecasted production needs, or qualify a replacement. No official successor part is listed on the Infineon lifecycle notice, so a pin-compatible substitute must be evaluated from the broader BAV70 family or an alternative dual common-cathode diode in SC-70.
The SC-70 (SOT-323) package is one of the smaller standard surface-mount outlines — about 2.0 mm × 1.25 mm body with three leads on 0.65 mm pitch. The key is getting the solder paste volume right: too much and the part floats, too little and the joint wicks up the lead. Pin 1 identification is marked by a bevel on the package body — look for the chamfered corner. The common cathode is on pin 2 (the centre lead), with the two anodes on pins 1 and 3. Orientation is unambiguous once you spot the bevel.

Given the Last Buy status, buyers should expect limited stock in the spot market and plan accordingly.
