Product details

Schottky pair in a small signal role

It comes in a surface-mount SC-70 / SOT-323 package (supplier device package PG-SOT323).

Infineon lists the BAS4005WE6327BTSA1 as obsolete. For BOM lines already qualified to this part, the only supply route is the surplus and broker market.

What the 100 ps trr means for the circuit

The 100 ps reverse recovery time is the key differentiator here. A standard switching diode in the same current class would have a trr in the nanosecond range. That speed matters when the diode is used in a switching regulator's bootstrap or snubber, or in a high-frequency rectifier stage where reverse-recovery losses eat into efficiency.

The SC-70 / SOT-323 footprint (PG-SOT323) is a common small-signal package. If you are replacing this part on an existing board, the land pattern matches the standard SOT-323 layout.

Frequently asked questions

What is the best replacement for BAS4005WE6327BTSA1?

Infineon has not published an official replacement for the BAS4005WE6327BTSA1. A functionally similar part would be a dual common-cathode Schottky diode rated for at least 40 V and 120 mA per diode in an SC-70 package. The BAS4005W base number shares the same die; other manufacturers' equivalents in the same footprint (e.g., the BAT54 series family) should be evaluated for Vf, leakage, and trr match before substitution.
