The BAS16E6433HTMA1 is a standard switching diode from Infineon in the BAS16 family, housed in a PG-SOT23 surface-mount package. The 80 V reverse voltage rating and 250 mA average rectified current cover the typical range for small-signal protection and general-purpose switching in industrial and consumer electronics.
Last Buy – what the status means for your BOM
Infineon has flagged the BAS16E6433HTMA1 as Last Buy. That means the manufacturer has issued a last-time-buy notice, and once the remaining stock is consumed, this specific order code will no longer be produced. If this diode is on your BOM, you need to secure your lifetime buy quantity now, or qualify a replacement.
80 V / 250 mA – the voltage and current envelope
The 80 V reverse voltage and 250 mA forward current define the safe operating area. This is not a power rectifier; it is a small-signal diode for applications like flyback clamping in relay drivers, reverse polarity protection on low-current rails, or ESD suppression on signal lines. The 1.25 V forward drop at 150 mA is typical for a silicon switching diode in this current range.
PG-SOT23 package – footprint and thermal note
The PG-SOT23 package (equivalent to SOT-23-3) is a standard three-lead surface-mount footprint. The package is small, which helps with board space but limits power dissipation.
