Product details
Overview
BAV199DW-7 from Diodes Incorporated is a quad surface-mount low-leakage switching diode in SOT363 package, comprising four independent silicon epitaxial planar diodes with 85 V peak reverse voltage, 160 mA forward current per element, and 5 nA max leakage at 75 V. It serves as signal-level clamping, polarity protection, and high-speed logic interface isolation in compact consumer and industrial PCBs.
For engineers reviewing the BAV199DW-7 datasheet, BAV199DW-7 pinout, BAV199DW-7 application, or BAV199DW-7 equivalent, key selection criteria include leakage current at elevated temperature, reverse recovery time under defined test conditions, junction capacitance at zero bias, thermal derating behavior, and SOT363 footprint compatibility with automated assembly.
Technical Context
The BAV199DW-7 integrates four discrete diodes in a single SOT363 package with common-cathode–anode pairing (AC1/A1/C1 and AC2/A2/C2), enabling dual-channel bidirectional signal routing or independent clamping paths. Its 3.0 µs reverse recovery time and 1.5 pF typical junction capacitance support operation up to ~100 MHz in RF detector and fast-switching logic applications.
Designed for low-power signal conditioning, it operates across –65°C to +150°C with 625°C/W junction-to-ambient thermal resistance on FR-4 board. Power dissipation is limited to 200 mW total package rating, derating linearly above 25°C ambient per the published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - maximum repetitive reverse voltage per diode; defines safe DC/peak AC blocking capability in clamp or protection circuits |
| IFM (per element) | 160 mA - continuous forward current rating per diode; sets usable signal amplitude range without thermal runaway |
| IR @ 75 V | 5 nA max - ultra-low leakage at near-rated reverse bias; critical for precision sample-hold and high-impedance sensor interfaces |
| tRR | 3.0 µs - measured with IF = IR = 10 mA, IRR = 1 mA, RL = 100 Ω; determines minimum pulse separation in digital switching |
| CT @ 0 V | 1.5 pF typical - junction capacitance at zero bias; limits high-frequency insertion loss and bandwidth in RF coupling paths |
| RθJA | 625 °C/W - thermal resistance on standard FR-4 layout; requires trace width and copper area planning for >50 mW sustained dissipation |
| TJ Range | –65°C to +150°C - extended operating temperature window enables use in automotive under-hood and industrial motor-control environments |
Pinout & Package
SOT363 (SC-88) 6-pin plastic package with gull-wing leads, 0.65 mm pitch, and UL 94V-0 rated molding compound. Moisture sensitivity level 1 (MSL-1), lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input terminal for first diode element; connects to signal source requiring unidirectional conduction or clamping |
| 2 (C1) | Cathode of Diode 1 | Return path for Diode 1; shared cathode node with Pin 3 enables common-cathode dual-diode configuration |
| 3 (A2) | Anode of Diode 2 | Second independent anode; allows separate signal channel or differential pair clamping |
| 4 (C2) | Cathode of Diode 2 | Independent cathode for Diode 2; supports isolated output routing or split-rail protection |
| 5 (AC1) | Common Anode/Cathode Node | Internal connection point between Diode 1 and Diode 2; used for series or back-to-back configurations per schematic |
| 6 (AC2) | Alternate Common Node | Secondary internal interconnect; enables four-terminal arrangement for balanced signal handling or dual-path ESD suppression |
Key Features
| Feature | Design Value |
|---|---|
| Quad low-leakage diode integration | Four independent silicon epitaxial planar diodes in one SOT363 footprint-reduces board space by ~75% vs. discrete SOT23 equivalents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage quad diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7-F | Same SOT363 package, identical pinout, but 100 V VRRM and 4 nA IR @ 75 V - slightly tighter leakage spec | Better suited for 90 V transient suppression; otherwise functionally interchangeable in ≤85 V systems | Select when higher reverse margin or lower leakage is required without layout change |
| MMBD1204-7-F | Lower VRRM (70 V), higher VF (1.25 V typ @ 10 mA), same 1.5 pF CT and SOT363 footprint | Acceptable for 5 V–3.3 V logic clamping where reverse voltage stays below 60 V | Choose for cost-sensitive designs where 70 V rating suffices and leakage tolerance is relaxed |
Compared with BAV99DW-7-F, the BAV199DW-7 trades 15 V reverse margin for broader legacy compatibility; versus MMBD1204-7-F, it delivers superior reverse blocking and lower leakage at the expense of marginally higher forward drop.

FAQ
What is the maximum junction temperature for continuous operation?
The BAV199DW-7 has a specified operating junction temperature range of –65°C to +150°C. Continuous operation at +150°C is permitted only when power dissipation remains within the derated limit-approximately 50 mW at that temperature-based on the published power derating curve and 625°C/W thermal resistance on FR-4 board.
Can BAV199DW-7 be used in place of BAV99 in existing SOT363 layouts?
Yes-the BAV199DW-7 shares identical SOT363 mechanical dimensions, pinout, and soldering specifications with the BAV99 series. No PCB redesign is needed; however, its 85 V VRRM is 15 V lower than the BAV99's 100 V rating, so system-level reverse voltage stress must remain below 85 V.
Is the leakage current specification guaranteed at elevated temperature?
Yes-datasheet Table "Electrical Characteristics" explicitly lists IR ≤ 80 nA at VR = 75 V and TJ = +150°C. This high-temperature leakage value is production-tested and guaranteed, making the device suitable for under-hood automotive and industrial control applications where thermal stability is critical.
Does the SOT363 package support reflow soldering per J-STD-020?
Yes-the BAV199DW-7 is qualified for standard Pb-free reflow per J-STD-020, with moisture sensitivity level (MSL) 1, meaning unlimited floor life at ≤30°C/60% RH. The matte tin annealed finish ensures reliable wetting and joint formation during peak reflow temperatures up to 260°C.
