Product details

What this BAV99W diode pair is

The Infineon BAV99WE6433BTMA1 is a standard switching diode with two die in a series-connected configuration inside a single SOT-323 package. It is rated for 80 V DC reverse voltage and 200 mA average rectified current per diode, with a reverse recovery time of 4 ns. The part is a surface-mount device in the SC-70 / SOT-323 case (PG-SOT323 supplier package), suited for general-purpose switching, ESD clamping, and polarity protection in low-current signal paths.

This exact suffix variant (BAV99WE6433BTMA1) is listed as obsolete. If your design can accept a different manufacturer or package suffix, the BAV99W function is broadly second-sourced; verify pin-compatibility and electrical ratings with the alternate datasheet before committing the change.

4 ns trr — what it buys you in a signal path

The 4 ns reverse recovery time places this diode in the fast-switching class for small-signal work. It can cleanly clip fast transients, commutate low-current inductive loads, or serve as a steering diode in a logic-level multiplexer without introducing excessive storage delay. The 150 nA leakage at 70 V reverse bias is tight enough for battery-powered sense circuits where every microamp counts.

Frequently asked questions

What is the replacement for BAV99WE6433BTMA1?

The base BAV99W function is a standard industry part available from multiple manufacturers (e.g., Nexperia, ON Semiconductor, Diodes Inc.) in the same SOT-323 footprint. Verify the electrical ratings — particularly reverse voltage, forward current, and trr — match your design before substituting. There is no single factory-specified replacement for this exact Infineon reel suffix.
