Product details
Overview
BAV170-QVL from Nexperia is a low-leakage, medium-speed switching double diode in common cathode configuration, housed in an SOT23 surface-mount package. It delivers typ. 3 pA reverse current at 75 V, 0.8 µs reverse recovery time, and supports 500 mA repetitive peak forward current - enabling precision signal clamping and voltage protection in automotive sensor interfaces.
For engineers reviewing the BAV170-QVL datasheet, BAV170-QVL pinout, BAV170-QVL application, or BAV170-QVL equivalent, this dual diode is selected for low-current bias networks, ESD-sensitive analog front-ends, and AEC-Q101-compliant automotive signal conditioning where leakage-induced offset and timing jitter must be minimized.
Technical Context
The BAV170-QVL integrates two epitaxial silicon diodes sharing a single cathode terminal, optimized for low-leakage operation across −55 °C to +150 °C junction temperature. Its 2 pF capacitance at 0 V and 0.8 µs trr support high-frequency signal routing without charge injection distortion.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements including HTGB, HTRB, and temperature cycling. The device operates with ≤5 nA reverse current up to 125 °C and maintains stable forward voltage (0.9–1.25 V) across 1–150 mA forward current range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 75 V max - sets maximum DC blocking capability in bias or clamp circuits |
| Reverse Current (IR) | 3 pA typ. @ 75 V, 25 °C - enables nanoamp-level leakage-critical biasing in precision amplifiers |
| Reverse Recovery Time (trr) | 0.8 µs typ. - ensures minimal switching distortion in <1 MHz signal paths |
| Forward Voltage (VF) | 0.9 V @ 1 mA - reduces power loss and thermal drift in low-current sensing nodes |
| Peak Forward Current (IFRM) | 500 mA - supports transient surge handling in ESD protection networks |
| Diode Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - preserves signal integrity in RF-adjacent analog routing |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), qualified per AEC-Q101 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (anode of diode 1) | Independent input path for first diode; used for dual-rail clamping or differential signal steering |
| 2 | A2 (anode of diode 2) | Second independent anode; enables shared-cathode dual-direction protection without discrete parts |
| 3 | CC (common cathode) | Single return node for both diodes - simplifies PCB layout and reduces parasitic inductance in high-speed paths |
Key Features
| Feature | Design Value |
|---|---|
| Low leakage current | 3 pA typical at 75 V - prevents DC error accumulation in high-impedance feedback networks |
| Medium-speed switching | 0.8 µs trr - balances speed and low-noise performance for <1 MHz sensor interfaces |
| Common cathode topology | Shared cathode pin - eliminates need for external parallel connection, reducing layout area and parasitic coupling |
| AEC-Q101 qualification | Qualified for automotive under stress tests including HTGB and temperature cycling - ensures long-term reliability in engine control modules |

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-Q | Higher IR (5 nA typ. @ 75 V); same SOT23 package and pinout | Less suitable for sub-10 nA bias networks but acceptable for general-purpose ESD clamping | Select when leakage tolerance >5 nA and cost optimization is prioritized over ultra-low leakage |
| MMBD1204 | Lower VR (70 V); higher trr (4 µs); TO-236AB package with identical pinning | Not AEC-Q101 qualified; limited to commercial-temperature industrial use | Choose only for non-automotive designs where 75 V blocking and 0.8 µs trr are not required |
Compared with BAV199-Q and MMBD1204, the BAV170-QVL provides the lowest leakage (3 pA) and fastest recovery (0.8 µs) in an AEC-Q101-qualified SOT23 package - making it the sole option for automotive analog signal chains requiring nanoscale leakage control and sub-microsecond timing fidelity.

FAQ
What is the maximum continuous reverse voltage rating for BAV170-QVL?
The BAV170-QVL has a maximum continuous reverse voltage (VR) rating of 75 V per diode at Tj = 25 °C, as specified in the Absolute Maximum Ratings table. This value decreases with rising junction temperature and must be derated per the thermal curves in Figure 1 of the datasheet.
Is BAV170-QVL pin-compatible with BAV199-Q?
Yes - BAV170-QVL and BAV199-Q share identical SOT23 package dimensions, pin numbering (A1–A2–CC), and terminal assignments. Both devices can be substituted on the same footprint without layout changes, though leakage and recovery performance differ.
Does BAV170-QVL support wave soldering?
Yes - the device is qualified for wave soldering using the footprint shown in Figure 9 of the datasheet (sot023_fw), with recommended solder mask openings and transport direction alignment. Peak temperature must remain below 260 °C for ≤10 seconds per JEDEC J-STD-020.
What is the thermal resistance from junction to ambient for BAV170-QVL?
The thermal resistance from junction to ambient (Rth(j-a)) is 500 K/W when mounted on a standard FR4 PCB with single-sided copper and tin plating, as measured in free air. This value assumes the device is placed on the recommended reflow footprint per Figure 8.
