Two fast switching diodes in a series pair
The Infineon BAV99UE6359HTMA1 is a dual series-connected switching diode array in a PG-SC74-6 surface-mount package. Each diode is rated for 80 V reverse voltage and 100 mA average rectified current, with a 4 ns reverse recovery time that suits high-speed clamping and signal steering. The two diodes are internally wired as a series pair, making it a drop-in for the classic BAV99 configuration in a compact six-pin SC-74 footprint.
Automotive-grade qualification
The operating junction temperature is rated up to 150°C, which covers under-hood and engine-bay thermal environments. The 80 V reverse voltage gives healthy margin on 12 V and 24 V automotive rails, while the 150 nA leakage at 70 V keeps quiescent draw negligible in always-powered modules.
Last-time-buy — plan your final order
Infineon has placed the BAV99UE6359HTMA1 into Last Buy status. That means the final production window is open now, and once it closes this exact suffix will no longer be manufactured. If you have an active BOM using this order code, this is the time to secure lifetime-buy quantities or qualify a drop-in alternative.
PG-SC74-6 footprint and hand-solderability
The PG-SC74-6 package is a six-lead small-outline transistor outline, roughly 2.9 mm × 1.6 mm body. The leads are gull-wing and spaced at 0.95 mm pitch, which is hand-solderable with a fine tip and magnification — no hot-air rework required.
