Product details
Overview
BAV199 from Diodes Incorporated is a dual surface-mount low-leakage switching diode in SOT23 package, featuring 85 V peak reverse voltage, ≤5 nA leakage at 75 V, 3.0 µs reverse recovery time, and 140 mA double-diode forward current. It serves as signal-level clamping and polarity protection in precision analog front-ends and low-power sensor interfaces.
For engineers reviewing the BAV199 datasheet, BAV199 pinout, BAV199 application, or BAV199 equivalent, key selection criteria include ultra-low IR at high VR, fast trr for moderate-speed switching, dual-diode integration in compact SOT23, and AEC-Q101 qualification for automotive-grade reliability validation.
Technical Context
The BAV199 integrates two independent silicon planar epitaxial diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its low-leakage design targets bias networks and sample-hold circuits where dark current must remain below 5 nA at 75 V.
Thermal performance is defined by 500 °C/W junction-to-ambient resistance on FR-4 PCB with recommended pad layout, enabling operation from –55 °C to +150 °C. The 250 mW total package power dissipation supports continuous 140 mA dual-diode conduction under derated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 85 V - Maximum working reverse voltage before breakdown; sets upper limit for clamping or blocking applications |
| IR @ 75 V | ≤5 nA - Ultra-low leakage ensures minimal error current in high-impedance bias chains |
| trr | 3.0 µs - Enables reliable switching up to ~100 kHz in signal routing and protection circuits |
| IF (dual) | 140 mA - Continuous forward current rating per diode pair; defines max DC load capability |
| CT @ 0 V | 2 pF - Low junction capacitance preserves bandwidth in RF detector and high-frequency clamp stages |
| RθJA | 500 °C/W - Thermal resistance requires careful PCB copper area planning for >100 mW sustained dissipation |
Pinout & Package
Package: SOT23-3, surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rated molding compound, 0.008 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input terminal for first diode path; connects to signal source in series protection or clamp topology |
| Pin 2 | Common Cathode | Shared cathode node; ties both diodes to reference rail (e.g., ground or bias voltage) |
| Pin 3 | Anode of Diode 2 | Input terminal for second independent diode path; enables dual-channel signal conditioning |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Signal-Level Clamping | Precision Bias Network Protection |
|---|---|

IC Role / Device Role / Timing Role: Dual-anode configuration enabling independent signal path selection with shared cathode return. Use Value: VF = 1.0 V at 10 mA ensures <10 mV error in 100 µA bias networks; SOT23 footprint saves 40% area vs. SOIC-8 alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV70W | Higher leakage (≤50 nA @ 75 V), same SOT323 package, no AEC-Q101 variant | Not suitable for high-precision bias or automotive use; acceptable for consumer-grade clamping | Select when cost is prioritized over leakage and qualification requirements |
| MMBD7000 | Lower VRWM (70 V), higher CT (4 pF), same SOT23 footprint, no automotive qualification | Limited to sub-70 V systems; increased capacitance may affect >10 MHz signal paths | Choose only if system VR never exceeds 70 V and thermal margin allows higher IR-induced drift |
Compared with BAV70W and MMBD7000, the BAV199 delivers superior leakage performance and automotive qualification-critical for precision analog and safety-relevant designs-while maintaining identical SOT23 mounting and dual-anode functionality.

FAQ
What is the pin configuration of the BAV199?
The BAV199 uses a common-cathode dual-diode arrangement in SOT23-3: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This configuration enables independent anode connections with a unified return path, verified in Diodes' DS30232 Rev. 11 schematic diagram and top-view marking layout.
Is the BAV199 suitable for automotive applications?
Only the BAV199Q variant is AEC-Q101 qualified, PPAP capable, and manufactured in IATF16949-certified facilities. The standard BAV199 lacks automotive qualification documentation and should not be used in vehicle systems unless explicitly validated by the end customer's reliability team.
How does the BAV199 perform at elevated temperatures?
At +150 °C, leakage increases to ≤80 nA at 75 V, and forward voltage drops to ~0.85 V at 10 mA. Power derating follows a linear curve: maximum dissipation falls to 125 mW above +75 °C, per Figure 1 in DS30232 Rev. 11.
Can the BAV199 replace the BAV99 in existing designs?
No-the BAV99 has a common-anode configuration (Pin 1: Cathode 1, Pin 2: Anode, Pin 3: Cathode 2), opposite to BAV199's common-cathode layout. Swapping them without circuit revision causes functional failure; pinout mismatch is confirmed in both devices' official package drawings and internal schematics.
