Product details
Overview
BAV170QA from Nexperia is a dual common cathode low-leakage switching diode in a DFN1010D-3 (SOT1215) package, rated for 75 V reverse voltage, 320 mA forward current per diode, and featuring 0.8 µs typical reverse recovery time and 3 pA typical reverse leakage at 75 V - used in precision analog front-ends and low-current signal routing.
For engineers reviewing the BAV170QA datasheet, BAV170QA pinout, BAV170QA application, or BAV170QA equivalent, this part is selected for ultra-low leakage, high-speed switching in space-constrained PCB layouts where AOI-compatible side-wettable flanks and thermal performance under 230 K/W junction-to-solder-point resistance are critical.
Technical Context
The BAV170QA integrates two independent silicon switching diodes sharing a single cathode terminal, enabling compact dual-path rectification or polarity-selective clamping without cross-coupling. Its low 2 pF capacitance and sub-nanosecond trr support RF detector and sample-hold circuit operation up to ~100 MHz.
Designed for surface-mount reflow on FR4 with standard footprint, it leverages side-wettable flanks for automated optical inspection of solder joints and achieves 540 mW total power dissipation with 1 cm² cathode pad - optimized for thermally sensitive low-power sensor nodes and battery-operated instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 75 V - maximum DC blocking capability per diode at 25 °C; defines safe operating range in bias networks and level-shifting circuits |
| IF (Forward Current) | 320 mA per diode - continuous current handling with derating above 25 °C; supports moderate-signal logic interface and LED drive |
| IR (Reverse Leakage) | 3 pA typical at 75 V, 25 °C - enables nanoampere-level current integrity in high-impedance sensor buffers and reference dividers |
| trr (Reverse Recovery) | 0.8 µs typical - ensures minimal switching distortion in 1–10 MHz signal routing and fast edge detection applications |
| Cd (Diode Capacitance) | 2 pF at 0 V, 1 MHz - preserves signal rise time and minimizes crosstalk in RF sampling and high-frequency multiplexing |
| Rth(j-sp) | 230 K/W - junction-to-solder-point thermal resistance with 1 cm² cathode pad; enables reliable thermal management in dense layouts |
Pinout & Package
Encapsulated in a leadless, ultra-thin DFN1010D-3 (SOT1215) package measuring 1.1 mm × 1.0 mm × 0.37 mm, with side-wettable flanks for AOI-compliant solder joint inspection and enhanced thermal conduction via the exposed cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first diode path; connects to signal source or supply rail requiring unidirectional conduction |
| 2 | Anode (Diode 2) | Independent input terminal for second diode path; allows dual-channel clamping or OR-ing without shared anode impedance |
| 3 & 4 | Common Cathode | Shared output node for both diodes; provides low-inductance return path and thermal anchoring to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low reverse leakage | 3 pA typical at 75 V - maintains accuracy in picoampere-range current sources and electrometer-grade measurement paths |
| High-speed switching | 0.8 µs trr - enables clean signal transitions in 10 MHz clock distribution and pulse shaping circuits |
| Miniaturized thermal package | DFN1010D-3 with 0.37 mm height and side-wettable flanks - fits 0402-class board area while supporting AOI and efficient heat transfer |
| Low junction capacitance | 2 pF - reduces loading on high-impedance nodes in RF detector inputs and analog switch control lines |
Applications
| High-Impedance Sensor Interface | Precision Reference Clamping |
|---|---|
Use Scenario: Front-end protection and biasing of pH electrodes, photodiode transimpedance amplifiers, or MEMS sensor signal chains. IC Role / Device Role / Timing Role: Low-leakage clamp diode limiting input swing to ±0.9 V while preserving nanoampere-level bias currents. Use Value: Prevents op-amp saturation without injecting >3 pA error current into 100 MΩ+ sensor impedances. | Use Scenario: Stabilizing voltage references in data acquisition systems using dual-path overvoltage protection. IC Role / Device Role / Timing Role: Dual-anode clamp referencing a common stable ground point to suppress transient excursions on REF+ and REF− lines. Use Value: Maintains <1 ppm reference drift during ESD events by limiting excursion to <1.1 V forward drop at 10 mA. |
| RF Signal Sampling | Low-Power Logic-Level Translation |
Use Scenario: Peak detection and envelope extraction in 10–50 MHz IF stages of portable radios and IoT receivers. IC Role / Device Role / Timing Role: Fast-switching detector diode with minimal capacitive loading on tuned tank circuits. Use Value: Delivers 95% amplitude fidelity at 30 MHz due to 2 pF Cd and 0.8 µs trr, avoiding harmonic distortion. | Use Scenario: Bidirectional level shifting between 1.8 V microcontroller GPIOs and 3.3 V peripheral interfaces in wearables. IC Role / Device Role / Timing Role: Passive dual-diode OR gate implementing open-drain logic translation with no active biasing. Use Value: Enables sub-1 µA quiescent current translation with <10 ns propagation delay and no external pull-up dependency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV199,115 | Higher IR (5 nA typ), larger SOT-323 package (2.1 × 1.25 mm), no side-wettable flanks | Lacks AOI compatibility and thermal performance for ultra-dense layouts | Select when legacy footprint compatibility outweighs leakage and size requirements |
| PMEG3010CEAX | Lower VR (30 V), Schottky architecture (no trr spec), higher Cd (10 pF) | Suitable only for low-voltage, high-capacitance-tolerant applications like USB port protection | Choose only for <30 V systems where ultra-fast switching is unnecessary and leakage <100 nA is acceptable |
Compared with BAV199 and PMEG3010CEAX, the BAV170QA uniquely combines picoampere leakage, sub-microsecond recovery, and AOI-ready DFN packaging - making it the sole option for miniaturized, high-fidelity analog signal conditioning where leakage-induced offset and thermal density are design-limiting factors.

FAQ
What is the maximum junction temperature rating for BAV170QA?
The absolute maximum junction temperature (Tj) is 150 °C, verified per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of leakage performance and forward voltage stability. Derating begins at 25 °C ambient, with total power dissipation dropping linearly to zero at 125 °C ambient for single-diode operation on standard FR4.
Is BAV170QA qualified for automotive applications?
No - BAV170QA is explicitly designated as non-automotive qualified per Nexperia's revision history (v.2, October 2025). It lacks AEC-Q101 qualification, automotive-grade process controls, and extended temperature validation. For automotive use, Nexperia recommends its -Q qualified alternatives such as BAV170QA-Q, which undergoes full stress testing per AEC standards.
How does the DFN1010D-3 package support automated optical inspection?
The DFN1010D-3 package features side-wettable flanks - exposed metal terminals along the package edges - enabling camera-based solder joint inspection of fillet profile, wetting angle, and voiding. This eliminates reliance on X-ray for bottom-terminal verification and improves first-pass yield in high-volume SMT lines using standard AOI equipment calibrated for 0402-class components.
Can BAV170QA be used in place of a single discrete diode?
Yes - either anode (Pin 1 or Pin 2) can be used independently with the common cathode (Pins 3 & 4) as a standalone low-leakage diode. The unused anode must be left floating or tied to a non-conflicting potential; no internal coupling exists between the diodes beyond the shared cathode node, preserving isolation of forward voltage and leakage characteristics per channel.
