Product details

What the 4 ns trr means for your snubber or clamp

The Infineon BAV99E6327 is a standard switching diode in a 1-pair series configuration — two diodes in one SOT-23-3 package with the cathode of one tied to the anode of the other. The 4 ns trr and 80 V Vr suit snubbing on switch nodes and signal-line clamping.

Infineon lists the BAV99E6327 as Obsolete. If you have this on a BOM, you are looking at the surplus and independent-distribution channel for remaining inventory. The base product number is BAV99, and the E6327 suffix is Infineon's reel-packaging code (Tape & Reel). Many BAV99 variants from multiple manufacturers share the same die and SOT-23-3 footprint, so a pin-to-pin alternate from Nexperia, ON Semiconductor, Diodes Inc, or Rohm is typically a straight swap — same series-diode topology, same 80 V / 200 mA / 4 ns trr ratings. The key is verifying the package marking and the Vf / trr match your design margin, not just the footprint.

Sourcing the BAV99E6327 today

We source it through our independent-distribution network — verified stock from surplus, overstock, and broker channels. Each unit is visually inspected and electrically sampled against the datasheet parameters before it ships. If you need a production-quantity BAV99 and the E6327 suffix is not a fixed requirement, we can also quote the active BAV99 variants from other manufacturers as a dual-source option for your BOM review.

Frequently asked questions

What is the replacement for BAV99E6327?

There is no single Infineon-specified replacement for the E6327 suffix (which is a reel-packaging code). However, the base BAV99 die and SOT-23-3 package are standard across the industry. Pin-compatible equivalents from Nexperia (BAV99,215), ON Semiconductor (BAV99LT1G), Diodes Inc (BAV99-7-F), and Rohm (BAV99) share the same 80 V Vr, 200 mA Io, and 4 ns trr ratings. Verify the package marking and forward voltage at your operating current before substituting.

What is the difference between BAV99 and BAV99E6327?

The BAV99 is the base product number for the series-connected dual switching diode in SOT-23. The E6327 suffix is Infineon's ordering code for Tape & Reel packaging. The silicon die, ratings (80 V, 200 mA, 4 ns trr), and SOT-23-3 footprint are identical. Any BAV99 from any manufacturer with the same ratings is functionally the same part.
