Product details
Overview
BAV199Q-7-F from Diodes Incorporated is a dual low-leakage surface-mount silicon switching diode in SOT23 package, rated for 85 V peak reverse voltage, 140 mA double-diode forward current, and 3.0 µs reverse recovery time; it serves as signal-level clamping and polarity protection in automotive sensor interfaces and precision analog front-ends.
For engineers reviewing the BAV199Q-7-F datasheet, BAV199Q-7-F pinout, BAV199Q-7-F application, or BAV199Q-7-F equivalent, key selection criteria include leakage current ≤5.0 nA at 75 V, thermal resistance of 500 °C/W, AEC-Q101 qualification, and dual-diode configuration in compact SOT23 footprint.
Technical Context
The BAV199Q-7-F integrates two independent silicon PN junction diodes in a single SOT23-3 package with common cathode connection (Pin 2), enabling bidirectional clamping or dual-path signal conditioning without discrete placement. Its 2 pF typical junction capacitance at 0 V and 3.0 µs reverse recovery support high-frequency signal integrity up to ~10 MHz.
Designed for automotive-grade reliability, it operates across −55 °C to +150 °C, features matte tin-plated alloy 42 leads, and meets IATF 16949 manufacturing standards with PPAP capability - critical for engine control modules and ADAS sensor signal chains requiring stable leakage performance under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - maximum repetitive reverse voltage before breakdown; ensures robustness against transients in 12 V automotive systems. |
| IR @ 75 V | ≤5.0 nA at TA = 25 °C - ultra-low leakage preserves signal fidelity in high-impedance sensor bias networks. |
| VF @ 10 mA | 1.0 V typical - low forward drop minimizes power loss and voltage error in precision clamp circuits. |
| trr | 3.0 µs - fast recovery enables use in moderate-speed digital signal routing and ESD protection paths. |
| CT @ 0 V | 2 pF - minimal junction capacitance avoids signal distortion in RF-coupled or high-speed analog inputs. |
| RθJA | 500 °C/W - thermal resistance defines derating curve; limits continuous power dissipation to 250 mW at 25 °C ambient. |
| TJ Range | −55 °C to +150 °C - extended temperature operation supports under-hood and transmission-control module deployment. |
Pinout & Package
Package: SOT23-3, surface-mount plastic case with moisture sensitivity level 1 (J-STD-020), 0.008 g mass, UL 94V-0 rating, and matte tin finish on alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first diode path; connects to signal source in clamp or protection topology. |
| Pin 2 | Common Cathode | Shared cathode terminal for both diodes; ties to reference rail (e.g., VCC or GND) in dual-clamp configuration. |
| Pin 3 | Anode of Diode 2 | Input node for second diode path; enables symmetrical bidirectional clamping or dual-signal routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine management and body electronics per stress test requirements. |
| Ultra-low IR | ≤5.0 nA at 75 V ensures <1 µV offset error in 1 MΩ sensor feedback loops at room temperature. |
| SOT23-3 footprint | Standardized 2.9 mm × 1.3 mm outline enables automated placement and PCB space savings vs. SOIC or SC-70 alternatives. |
| Lead-free & green | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
Applications
| Automotive Sensor Interface | Precision Analog Clamp |
|---|---|
Use Scenario: Protecting Hall-effect or thermistor inputs in engine control units from load-dump transients and ESD events. IC Role / Device Role / Timing Role: Dual-diode clamping network limiting input voltage to ±0.7 V beyond supply rails. Use Value: 85 V VRRM withstands ISO 7637-2 Pulse 1/2a surges; 5 nA leakage prevents DC bias shift in µA-level sensor currents. | Use Scenario: Biasing and protecting op-amp inputs in medical-grade instrumentation amplifiers. IC Role / Device Role / Timing Role: Low-capacitance (2 pF), fast-recovery (3 µs) clamp preventing saturation during overvoltage events. Use Value: Minimal CT avoids phase shift in kHz-range bio-signal acquisition; 1.0 V VF ensures predictable clamping threshold. |
| Industrial IO Protection | Low-Power Signal Routing |
Use Scenario: Input protection for PLC analog input modules exposed to field-wiring induced noise and surge. IC Role / Device Role / Timing Role: Common-cathode dual diode shunting transient energy to VDD/GND rails. Use Value: AEC-Q101 qualification correlates with enhanced reliability under vibration and thermal cycling; 150 °C TJ max supports uncooled enclosures. | Use Scenario: Level-shifting and polarity correction in battery-powered IoT sensor nodes with limited headroom. IC Role / Device Role / Timing Role: Two independent anodes allow selective signal path enablement via external control. Use Value: 140 mA double-diode IF rating supports 3.3 V/5 V logic-level signal conditioning without derating; SOT23 enables miniaturized PCB layout. |
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 |
|---|---|---|---|
| BAV21W-7-F | Single diode, 250 V VRRM, 200 mA IF, 50 nA IR @ 200 V - higher voltage rating but no dual configuration. | Requires two devices for dual-path function; unsuitable for space-constrained common-cathode layouts. | Select when >85 V standoff is required and board area permits duplication. |
| MMBD7000LT1G | Dual diode, 70 V VRRM, 200 mA IF, 100 nA IR @ 50 V - lower voltage rating and higher leakage than BAV199Q-7-F. | Acceptable for 5 V/3.3 V systems but not for 12 V automotive transients; less suitable for high-temperature operation. | Choose for cost-sensitive consumer applications where 70 V rating suffices and 150 °C operation is unnecessary. |
Compared with BAV21W-7-F and MMBD7000LT1G, the BAV199Q-7-F uniquely balances 85 V standoff, sub-5 nA leakage at elevated voltage, AEC-Q101 qualification, and integrated dual-diode SOT23 packaging - making it optimal for automotive and industrial signal integrity where space, leakage, and reliability are co-constrained.

FAQ
What is the pin configuration of BAV199Q-7-F?
The BAV199Q-7-F uses a SOT23-3 package with Pin 1 as Anode 1, Pin 2 as Common Cathode, and Pin 3 as Anode 2. This configuration enables bidirectional clamping or dual independent signal paths sharing one cathode node, verified by Diodes' official top-view schematic and internal marking diagram.
Is BAV199Q-7-F suitable for automotive applications?
Yes - the "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities. It is explicitly rated for −55 °C to +150 °C operation and designed for engine control, transmission, and ADAS sensor interface applications per Diodes' automotive product definitions.
How does leakage current behave at elevated temperature?
At VR = 75 V and TJ = +150 °C, leakage rises to ≤80 nA - still within low-leakage classification. This is confirmed in the Electrical Characteristics table (Note 7) and supported by Fig. 3's reverse current curves showing <100 nA at 75 V and 150 °C.
Can BAV199Q-7-F replace BAV199-7-F in existing designs?
Yes - both share identical electrical specifications, package, and pinout. The "Q" variant adds automotive qualification and green material compliance; standard BAV199-7-F lacks AEC-Q101 validation and may use non-halogen-free molding compound depending on date code (pre-V9).
