Product details
Overview
BAV170-QR from Nexperia is a low-leakage, medium-speed switching double diode in SOT23 package with common cathode configuration, rated for 75 V continuous reverse voltage, 500 mA repetitive peak forward current, and typ. 3 pA reverse leakage at 75 V - used in precision biasing and signal clamping circuits in automotive sensor interfaces.
For engineers reviewing the BAV170-QR datasheet, BAV170-QR pinout, BAV170-QR application, or BAV170-QR equivalent, this page delivers verified electrical parameters, validated SOT23 pin mapping, AEC-Q101 qualification status, thermal resistance data (Rth(j-a) = 500 K/W), and real-world use cases in low-current analog front-ends.
Technical Context
The BAV170-QR integrates two epitaxial silicon diodes sharing a single cathode terminal, enabling compact dual-channel clamping or steering without cross-coupling. Its 0.8 µs typical reverse recovery time supports medium-frequency signal routing up to ~500 kHz.
Designed for operation across −55 °C to +150 °C ambient, it maintains sub-5 nA reverse current up to 125 °C and exhibits 2 pF junction capacitance at 0 V - critical for minimizing loading in high-impedance voltage reference paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 75 V max - defines maximum DC blocking capability per diode in steady-state bias networks |
| Reverse Leakage (IR) | 3 pA typ. @ 75 V, 25 °C - enables nanoampere-level current integrity in precision op-amp feedback or sensor biasing |
| Reverse Recovery Time (trr) | 0.8 µs typ. - supports clean switching in 1–2 MHz digital signal conditioning without tail current distortion |
| Forward Voltage (VF) | 0.9 V max @ 1 mA, 25 °C - ensures minimal voltage drop in low-power rail-clamp protection |
| Junction-to-Ambient Rth | 500 K/W - requires PCB copper area planning for >125 mA continuous operation at 70 °C ambient |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV) |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for FR4 PCBs with single-sided copper and standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; connects to signal source or supply rail requiring clamping |
| 2 | Anode (Diode 2) | Independent input node for second diode path; enables dual-rail or differential clamping |
| 3 | Common Cathode | Shared output/return node; simplifies PCB routing and reduces parasitic inductance in high-speed layouts |
Key Features
| Feature | Design Value |
|---|---|
| Low leakage current | 3 pA typ. @ 75 V - preserves accuracy in µA-range current sources and high-Z sensor interfaces |
| Common cathode topology | Single shared cathode terminal - reduces component count and layout area vs. discrete dual-diode solutions |
| Medium-speed switching | 0.8 µs trr - balances speed and low leakage better than Schottky alternatives in <1 MHz analog signal chains |
| AEC-Q101 qualification | Qualified for automotive under stress test conditions - supports deployment in engine control, ADAS sensor modules, and infotainment power rails |
Applications
| Automotive Sensor Biasing | High-Impedance Signal Clamping |
|---|---|
Use Scenario: Providing stable bias current to MEMS pressure sensors in engine control units under wide temperature swings. IC Role / Device Role / Timing Role: Dual-diode clamp protecting op-amp inputs from transients while maintaining nanoampere-level bias stability. Use Value: Sub-5 nA leakage up to 125 °C prevents drift in ratiometric sensor outputs; common cathode minimizes board space in tight ECU modules. |
Use Scenario: Protecting ADC inputs in industrial data loggers from ESD-induced overvoltage during field wiring. IC Role / Device Role / Timing Role: Fast-recovery dual clamp limiting input swing to ±0.9 V while preserving signal fidelity below 100 kHz. Use Value: 0.8 µs trr avoids pulse distortion; 2 pF capacitance prevents attenuation of high-frequency noise monitoring signals. |
| Low-Power Reference Protection | Dual-Rail Power Sequencing |
Use Scenario: Isolating precision voltage references (e.g., REF5025) from transient coupling on adjacent LDO outputs. IC Role / Device Role / Timing Role: Reverse-biased diode pair shunting surge energy away from reference node without loading quiescent current. Use Value: 3 pA leakage ensures <0.1 ppm reference error contribution; SOT23 footprint allows placement directly at reference IC pins. |
Use Scenario: Enabling controlled power-up sequencing between 3.3 V and 5 V domains in telematics gateways. IC Role / Device Role / Timing Role: Anode-to-anode connection forming OR-ing diode pair with independent anode routing and shared cathode return. Use Value: 75 V VR rating accommodates 5 V rail overshoot; 500 mA IFRM supports brief inrush during hot-plug events. |
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. @ 75 V), slower trr (3 µs typ.), same SOT23 package and common cathode pinout | Less suitable for <100 nA bias networks but acceptable in general-purpose ESD clamping | Select when cost sensitivity outweighs leakage-critical performance; verify trr impact on signal edge integrity |
| MMBD1204 | Lower VR (100 V), higher VF (1.25 V @ 10 mA), AEC-Q101 qualified, same pinout | Better for higher-voltage clamping but introduces larger forward drop in low-voltage reference paths | Prefer where system transients exceed 75 V; avoid in sub-1 V signal rails due to VF penalty |
Compared with BAV199 and MMBD1204, the BAV170-QR uniquely combines ultra-low leakage (3 pA), fast recovery (0.8 µs), and automotive qualification in a single SOT23 device - making it optimal for high-accuracy, temperature-stable analog front-ends where both leakage and timing matter.

FAQ
Is BAV170-QR pin-compatible with BAV199?
Yes - both use identical SOT23 package and common cathode pinout (Pin 1: A1, Pin 2: A2, Pin 3: CC). However, BAV170-QR offers 6× lower typical leakage (3 pA vs. 5 nA) and faster trr (0.8 µs vs. 3 µs), making direct substitution viable only if those parameters meet design margins.
What is the maximum continuous forward current per diode at 85 °C ambient?
Per Figure 1 in the datasheet, the maximum permissible continuous forward current drops to 125 mA when both diodes are loaded and ambient temperature reaches 85 °C on FR4 PCB with standard footprint - due to thermal derating from 250 mW Ptot and 500 K/W Rth(j-a).
Does BAV170-QR support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint (Figure 9) with 1.4 mm pad width and 2.2 mm spacing. Recommended preheat ≤150 °C, peak temperature 260 °C for ≤5 s, and flux residue removal per IPC-J-STD-001 Class 3 requirements.
How does junction capacitance vary with reverse voltage?
Per Figure 5, Cd decreases from ~2 pF at 0 V to ~0.5 pF at 20 V reverse bias - enabling tunable AC coupling impedance in RF detector or envelope follower circuits without external bias networks.
