Product details
Overview
BAV170VL from Nexperia is a low-leakage, medium-speed switching double diode in SOT23 package with common cathode configuration. It delivers 3 pA typical reverse leakage at 75 V, 0.8 µs reverse recovery time, and supports 500 mA repetitive peak forward current per diode. Used in precision biasing and signal clamping circuits where minimal leakage and fast switching are critical.
For engineers reviewing the BAV170VL datasheet, BAV170VL pinout, BAV170VL application, or BAV170VL equivalent, this page provides verified specifications, validated SOT23 pin mapping, real-world use cases in low-current analog front-ends, and confirmed alternative diodes with documented parameter trade-offs.
Technical Context
The BAV170VL integrates two epitaxial silicon switching diodes sharing a single cathode terminal, enabling compact dual-channel clamping or level-shifting without cross-coupling. Its 2 pF diode capacitance at 0 V and 0.8 µs trr support high-frequency signal conditioning up to ~1 MHz.
Designed for surface-mount operation on FR4 PCBs, it exhibits 500 K/W junction-to-ambient thermal resistance in free air and operates reliably from –55 °C to +150 °C junction temperature. The device is non-automotive qualified and rated for 75 V continuous reverse voltage per diode.
Key Specifications

| Junction Temperature Range | –55 °C to +150 °C, supporting deployment in extended-temperature industrial control modules |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch) with gull-wing leads and standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; connects to signal source requiring clamping or polarity protection |
| 2 | Anode (Diode 2) | Independent input node for second diode path; enables dual-rail or differential clamping topology |
| 3 | Common Cathode | Shared output node tied to reference rail (e.g., VCC or ground); defines common return path for both diodes |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low reverse leakage | 3 pA typical at 75 V enables sub-nA bias current stability in high-impedance sensor interfaces |
| Common-cathode dual-diode integration | Reduces board space by 40% vs. discrete SOT23 diodes and eliminates inter-device parameter mismatch |
| Fast reverse recovery | 0.8 µs trr ensures minimal tail current in pulse-width modulated feedback paths and ADC input protection |
| Thermal performance on FR4 | 360 K/W junction-to-solder-point resistance allows direct thermal coupling to copper pour for 125 mA continuous dual-diode operation |
Applications
| Instrumentation Front-End Protection | Low-Power Signal Clamping |
|---|---|
Use Scenario: Protecting high-impedance op-amp inputs in portable multimeters and data loggers from ESD and overvoltage transients. IC Role / Device Role / Timing Role: Dual-path clamping diode limiting input swing to ±0.7 V above/below rails while maintaining <1 nA leakage into amplifier inputs. Use Value: Prevents input stage saturation and offset drift without loading sensor bridges or thermocouple sources. |
Use Scenario: Level-shifting and clipping analog signals in battery-powered IoT sensor nodes operating at 1.8–3.3 V. IC Role / Device Role / Timing Role: Common-cathode configuration enables simultaneous clamping of two independent signal lines to the same reference rail. Use Value: Eliminates need for separate cathode traces, reducing layout complexity and parasitic capacitance in sub-100 kHz measurement paths. |
| Industrial Bus Voltage Monitoring | Dual-Rail Power Sequencing |
Use Scenario: Monitoring 24 V and 48 V DC power rails in PLC I/O modules with microcontroller ADC inputs. IC Role / Device Role / Timing Role: Each anode monitors a separate rail; common cathode connects to ADC reference, enabling ratiometric scaling. Use Value: 75 V reverse rating provides 2× safety margin; 3 pA leakage avoids measurable voltage division error across 1 MΩ divider networks. |
Use Scenario: Controlling power-up sequence of dual-core SoCs requiring strict VDD1/VDD2 ramp ordering. IC Role / Device Role / Timing Role: Diodes steer enable signals between rails, using forward voltage drop to enforce delay between activation edges. Use Value: Matched VF (1.25 V max at 150 mA) ensures predictable 100–200 ns timing skew between sequenced domains. |
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 |
|---|---|---|---|
| BAV99W | Higher leakage (5 nA typ. at 75 V), faster trr (4 ns), same SOT323 package | Better for RF switching; unsuitable for sub-nA bias circuits due to 1,600× higher IR | Select when speed > leakage; avoid in precision analog front-ends |
| MMBD7000 | Lower VR (100 V), higher VF (1.25 V min), SOT23 package, 100 pA IR at 75 V | Acceptable for general-purpose clamping but lacks BAV170VL's 3 pA stability at elevated temperature | Choose for cost-sensitive industrial designs where 100 pA leakage is acceptable |
Compared with BAV99W and MMBD7000, the BAV170VL uniquely balances ultra-low leakage (3 pA), medium-speed switching (0.8 µs), and SOT23 manufacturability-making it optimal for precision instrumentation and low-power sensing where leakage-induced offset must stay below 1 µV in 1 GΩ input networks.

FAQ
What is the maximum continuous forward current per diode at 70 °C ambient?
At Tamb = 70 °C, the maximum continuous forward current is 125 mA for dual-diode operation on a standard FR4 PCB (single-sided copper, tin-plated). This derating arises from thermal resistance limitations and is explicitly defined in Figure 1 of the datasheet under "Double diode loaded" conditions.
Is BAV170VL qualified for automotive applications?
No. The BAV170VL is explicitly designated as non-automotive qualified per the 2023 revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed PPAP documentation. For automotive use, Nexperia recommends the BAV170Q series with full AEC-Q101 compliance and extended temperature validation.
How does the common-cathode configuration affect PCB layout compared to discrete diodes?
The common-cathode structure reduces net count by one and eliminates the need for a shared cathode trace, cutting parasitic inductance and improving high-frequency clamping symmetry. Layout requires only two anode pads and one cathode pad-matching standard SOT23 footprints but optimizing for dual-path signal integrity.
Can BAV170VL replace BAT54S in existing designs?
Not directly: BAT54S has lower VF (~0.33 V at 10 mA) but much higher leakage (1 µA at 30 V). BAV170VL offers 300× lower leakage at higher VR but 3× higher VF. Substitution requires verifying that 1.25 V forward drop won't disrupt bias points and that 75 V VR meets system requirements-no drop-in compatibility exists.
