The BAS7005E6433HTMA1 is a dual Schottky diode in a common-cathode configuration, rated for 70 V reverse voltage and 70 mA average rectified current per diode. The 100 ps reverse recovery time (trr) is the headline for switching applications — it recovers faster than a standard pn-junction diode, so in a high-frequency rectifier or a snubber network it won't add a significant reverse-recovery spike. This matters for circuits switching above a few MHz where a slower diode's stored charge becomes a loss and noise source.
Package and board-fit — SOT-23 footprint
Housed in a standard SOT-23-3 (PG-SOT23) surface-mount package, the BAS7005E6433HTMA1 mounts on the same footprint as countless other small-signal diodes. The common-cathode pinout means the two anodes are independent — the cathode is the shared pin, which simplifies PCB layout when you need two Schottky diodes in a single package for OR-ing or clamping a pair of signal lines. The junction temperature rating of 150°C max gives thermal headroom in a tight board — the SOT-23's small copper pad area is the limiting factor for heat dissipation, not the silicon itself. For continuous 70 mA per diode, keep the ambient below about 85°C unless you have a copper pour under the part.
Sourcing and compliance
The base product number is BAS7005, so the full order code BAS7005E6433HTMA1 includes the specific packaging (tape and reel) and Infineon's internal suffix.
