Product details
Overview
BAV170Q-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, 215 mA forward current per diode, and 3.0 µs reverse recovery time. It delivers <5 nA leakage at 75 V and 25°C, enabling precision signal clamping and high-impedance biasing in automotive sensor interfaces and analog front-ends.
For engineers reviewing the BAV170Q-7-F datasheet, BAV170Q-7-F pinout, BAV170Q-7-F application, or BAV170Q-7-F equivalent, key selection criteria include ultra-low IR at elevated temperature, AEC-Q101 qualification, SOT23 dual-diode layout, and tight VF matching across channels for balanced signal routing.
Technical Context
The BAV170Q-7-F integrates two independent epitaxial planar silicon diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its design targets high-speed, low-distortion signal conditioning where leakage-induced offset error must be minimized.
It operates across –55°C to +150°C with thermal resistance of 500°C/W and supports automotive-grade reliability via IATF 16949 manufacturing, PPAP capability, and AEC-Q101 stress testing - including HTGB, TCT, and ESD HBM ≥8 kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - blocks transient spikes up to 85 V in clamp/protection circuits without breakdown |
| IFM (per diode) | 215 mA - supports continuous signal path current in low-power analog switches and level shifters |
| IR @ 75 V, 25°C | <5 nA - ensures minimal DC error in high-gain op-amp feedback networks and sensor biasing |
| trr | 3.0 µs - enables reliable operation in 100–500 kHz switching applications like sample-and-hold and multiplexer guarding |
| VF @ 10 mA | 1.0 V typical - provides predictable forward drop for voltage reference trimming and logic-level translation |
| CT @ 0 V, 1 MHz | 2 pF - minimizes capacitive loading on RF-sensitive nodes such as antenna switch control lines |
| TJ Range | –55°C to +150°C - validated for under-hood automotive ECUs and industrial motor drive feedback sensing |
Pinout & Package
SOT23-3 plastic surface-mount package with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1 (J-STD-020); weight 0.008 g; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first signal path; connects to source in clamp configuration or input in OR-ing topology |
| Pin 2 | Common Cathode | Shared return path; ties both diodes to reference rail or ground plane for dual-channel symmetry |
| Pin 3 | Anode of Diode 2 | Input node for second independent signal path; enables space-efficient dual-signal routing |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including engine control modules and ADAS sensor interfaces |
| Ultra-low leakage | <5 nA @ 75 V, 25°C - preserves accuracy in high-impedance voltage dividers and precision current mirrors |
| Matched dual diodes | Consistent VF and trr between channels - simplifies differential signal handling and reduces calibration overhead |
| Lead-free & green | Halogen- and antimony-free; RoHS 3 compliant (≤900 ppm Br/Cl, ≤1000 ppm Sb) - meets global environmental compliance mandates |
Applications
| Automotive Sensor Signal Conditioning | High-Voltage Analog Multiplexing |
|---|---|
Use Scenario: Front-end protection and level shifting for thermistor, pressure, and position sensor signals in engine control units. IC Role / Device Role / Timing Role: Dual-diode clamp and bias isolation element placed before ADC input stage. Use Value: Prevents overvoltage damage while maintaining sub-nA leakage to avoid sensor offset drift at 150°C ambient. | Use Scenario: Channel selection and fault isolation in 8:1 analog multiplexers used in battery management systems. IC Role / Device Role / Timing Role: Back-to-back diode guard for each input channel to suppress cross-talk and leakage-induced crosstalk. Use Value: Enables stable 16-bit measurement integrity by limiting inter-channel leakage to <80 nA at 75 V and 150°C. |
| Low-Power Precision Reference Clamping | Industrial PLC Input Protection |
Use Scenario: Voltage reference stabilization in portable medical instrumentation requiring long-term zero-drift performance. IC Role / Device Role / Timing Role: Low-leakage clamp diode pair protecting bandgap reference outputs from ESD and transients. Use Value: Maintains reference stability with <0.5 µV/h drift contribution due to diode leakage below 5 nA at 25°C. | Use Scenario: Input surge suppression and polarity protection for 24 V digital inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent protection of two isolated field inputs sharing one common return. Use Value: Reduces PCB footprint by 40% versus discrete diodes while sustaining 500 mA non-repetitive surge per channel. |
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 |
|---|---|---|---|
| BAV99W-7-F | Higher IR (≤50 nA @ 75 V), same SOT23-3, lower VRRM (70 V) | Not AEC-Q101 qualified; suitable for commercial-grade consumer electronics only | Select when cost sensitivity outweighs automotive qualification and leakage budget allows 10× increase |
| MMBD7000LT1G | Lower VF (0.85 V typ @ 10 mA), higher trr (4.0 µs), same VRRM (85 V), no AEC-Q101 | Optimized for general-purpose switching rather than precision analog clamping | Prefer for high-speed digital logic clamping where speed > leakage is critical |
Compared with BAV99W-7-F and MMBD7000LT1G, the BAV170Q-7-F uniquely combines AEC-Q101 qualification, sub-5 nA leakage, and matched dual-channel performance - making it the only choice for automotive analog front-ends demanding long-term DC stability.

FAQ
What is the pin configuration of BAV170Q-7-F?
BAV170Q-7-F uses a SOT23-3 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This common-cathode dual-diode arrangement enables symmetrical clamping and bidirectional signal routing without external node tying.
Is BAV170Q-7-F suitable for high-temperature automotive applications?
Yes - it is AEC-Q101 qualified and specified for operation from –55°C to +150°C. Leakage remains below 80 nA at 75 V and 150°C, and thermal resistance (500°C/W) is validated on standard FR-4 layouts per Diodes' recommended pad dimensions.
How does BAV170Q-7-F differ from standard BAV170 variants?
The "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities. Electrically identical to non-Q versions, but with full automotive change control, lot traceability, and enhanced reliability testing including temperature cycling and HTGB.
Can BAV170Q-7-F replace BAV99 in existing designs?
Only with validation - though both are SOT23-3 dual diodes, BAV170Q-7-F has higher VRRM (85 V vs. 70 V), lower leakage (<5 nA vs. ≤50 nA), and AEC-Q101 qualification. Layout compatibility exists, but system-level retesting is required for automotive use cases.
