It pairs two diodes in series internally, saving board space compared to two discrete SOD-323 or SOT-23 devices. With an 80 V reverse voltage rating and 200 mA average forward current per diode, it handles 48 V and 60 V bus clamping, relay coil suppression, and general-purpose high-speed switching in industrial and telecom boards. ## 4 ns reverse recovery — the switching-speed spec that matters The 4 ns reverse recovery time (trr) is the headline switching parameter for this diode pair. It means the diode recovers from forward conduction to blocking in under 5 ns, which is fast enough for switch-mode power supply snubbers, high-speed logic clamping, and signal-line protection where the edge rate is in the nanosecond range. Slower diodes (trr > 50 ns) would ring or overheat in the same circuit. ## 80 V reverse voltage, 150 nA leakage — margin for industrial rails The 80 V maximum DC reverse voltage gives comfortable derating headroom on 48 V telecom rails (60% margin) and 24 V industrial supplies (70% margin). Reverse leakage is specified at 150 nA at 70 V reverse bias — low enough that it won't disturb high-impedance sense nodes or precision analog inputs. The 1.25 V forward drop at 150 mA is typical for a small-signal silicon switching diode; the junction temperature rating reaches 150°C, consistent with industrial ambient ranges. ## Obsolete — sourcing through independent distribution Infineon lists the BAV99SE6327BTSA1 as obsolete. For BOM lines that require this package marking and pinout, procurement runs through independent distribution and surplus channel. Date-code provenance matters here — buyers should verify fresh stock against the original Infineon specification.","metaTitle":"Infineon BAV99SE6327BTSA1 dual series switching diode","metaDescription":"Infineon BAV99SE6327BTSA1 dual series standard switching diode in PG-SOT363. 80 V reverse, 200 mA average, 4 ns trr.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"6-VSSOP, SC-88, SOT-363","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAV99S","Diode Configuration":"2 Pair Series Connection","Supplier Device Package":"PG-SOT363-PO","Reverse Recovery Time (trr)":"4 ns","Current - Reverse Leakage @ Vr":"150 nA @ 70 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.25 V @ 150 mA","Current - Average Rectified (Io) (per Diode)":"200mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c754167409a9cf53396e78b08b433586.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BAV99SE6327BTSA1 obsolete?","answer":"Yes, Infineon lists this part as obsolete.
