Product details
Overview
BAV170M from Nexperia is a dual common cathode low-leakage switching diode in a DFN1006-3 (SOT883) package, designed for precision signal routing and leakage-sensitive bias networks. It delivers 0.8 µs reverse recovery time, 3 pA typical reverse current at 75 V and 25 °C, 2 pF junction capacitance, and AEC-Q101 qualification for automotive use - deployed in ECU input protection and sensor front-end clamping circuits.
For engineers reviewing the BAV170M datasheet, BAV170M pinout, BAV170M application, or BAV170M equivalent, key selection criteria include ultra-low IR for standby power integrity, trr < 1 µs for high-frequency sampling hold, Cd ≤ 2 pF for minimal signal distortion in RF-coupled paths, and thermal resistance Rth(j-sp) = 190 K/W for compact PCB layouts.
Technical Context
The BAV170M integrates two independent silicon PN junction diodes sharing a single cathode terminal, enabling compact dual-path clamping or steering without inter-diode coupling. Its construction uses epitaxial planar technology to achieve sub-nA leakage and controlled carrier lifetime for fast recovery.
Thermal performance is defined by two distinct paths: Rth(j-a) = 385 K/W (standard FR4 footprint) and Rth(j-sp) = 190 K/W (cathode pad enhanced), allowing designers to select layout strategy based on power dissipation and board space constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse current (IR) | 3 pA typ @ 75 V, 25 °C - enables nanoampere-level standby current budgets in battery-backed sensors |
| Reverse recovery time (trr) | 0.8 µs typ - supports >1 MHz switching in sample-and-hold or peak-detect circuits |
| Junction capacitance (Cd) | 2 pF @ 0 V, 1 MHz - minimizes loading on high-impedance analog nodes and RF signal paths |
| Repetitive peak reverse voltage (VRRM) | 85 V - provides margin for transients in 24 V automotive supply rails and industrial I/O |
| Forward current (IF) | 320 mA per diode - sufficient for LED biasing, logic-level translation, and discrete gate driving |
| Package | DFN1006-3 (SOT883), 0.48 mm height - fits 0402-class footprints with 0.65 mm pitch for ultra-dense layouts |
Pinout & Package
Encapsulated in a leadless ultra-small DFN1006-3 (SOT883) plastic package with 0.48 mm profile, 0.62 mm × 0.55 mm body, and three solderable terminals on 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input path for first signal channel; connects to source or driver output in dual-rail clamping |
| 2 | Anode of Diode 2 | Independent input path for second channel; allows separate signal conditioning without shared anode impedance |
| 3 | Common Cathode | Single low-inductance return node for both diodes; simplifies grounding and reduces loop area in EMI-critical designs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments up to 150 °C junction temperature and mechanical shock/vibration profiles |
| Ultra-low leakage | 3 pA typical IR ensures <10 nW power loss per diode at 75 V - critical for energy harvesting and IoT sleep modes |
| High-speed recovery | 0.8 µs trr enables clean edge transitions in 1–2 MHz clock distribution and ADC front-end protection |
| Low-profile SMD | 0.48 mm max height permits placement under connectors or beneath shields in space-constrained modules |
| Thermally optimized cathode pad | Rth(j-sp) = 190 K/W enables 660 mW total power dissipation with minimal thermal derating on standard FR4 |
Applications
| Automotive Sensor Interface | Portable Medical Instrumentation |
|---|---|
Use Scenario: Protecting analog front-end inputs of pressure/temperature sensors in engine control units against load dump and ESD events. IC Role / Device Role / Timing Role: Dual-path clamping diode providing bidirectional overvoltage suppression while maintaining sub-picoampere leakage into precision op-amp inputs. Use Value: Prevents sensor offset drift caused by leakage-induced bias current errors, preserving ±0.1% measurement accuracy over temperature. |
Use Scenario: Isolating electrode inputs in portable ECG monitors during lead-off detection and defibrillation pulse rejection. IC Role / Device Role / Timing Role: Low-capacitance steering diode routing biopotential signals to differential amplifiers while blocking high-voltage transients. Use Value: 2 pF Cd avoids phase shift in 0.05–150 Hz bandwidth; 3 pA IR prevents DC baseline wander during multi-hour battery-operated sessions. |
| Industrial PLC Analog Input Modules | RF Signal Path Protection |
Use Scenario: Front-end protection for 4–20 mA current loop receivers exposed to field wiring surges and ground potential differences. IC Role / Device Role / Timing Role: Dual common-cathode configuration enables symmetrical clamping of both loop terminals to a stable reference rail. Use Value: Shared cathode reduces component count vs. discrete diodes; 85 V VRRM withstands 48 V system transients with 2× safety margin. |
Use Scenario: DC blocking and transient suppression in 2.4 GHz Wi-Fi antenna switch control lines and LNA bias feeds. IC Role / Device Role / Timing Role: Low-Cd, low-IR diode placed in series with RF control paths to block DC while passing RF with minimal insertion loss. Use Value: 2 pF capacitance yields <0.1 dB insertion loss at 2.4 GHz; 0.8 µs trr avoids harmonic generation during fast GPIO toggling. |
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 |
|---|---|---|---|
| BAV199W | Higher IR (5 nA typ), slower trr (4 µs), same DFN1006-3 package | Acceptable for general-purpose switching but unsuitable for nanoampere-biased sensor nodes | Select when cost sensitivity outweighs leakage or speed requirements |
| NSR0230P2T5G | Lower VRRM (30 V), higher IF (400 mA), different SOD-523 package | Limited to 12 V systems; incompatible with 24/48 V automotive or industrial rails | Choose only for low-voltage consumer electronics where board space allows larger footprint |
Compared with BAV199W and NSR0230P2T5G, the BAV170M uniquely balances sub-picoampere leakage, sub-microsecond recovery, and 85 V standoff in a 0.48 mm profile - making it the sole option for AEC-Q101-compliant, high-precision dual-clamp functions in constrained automotive and medical layouts.

FAQ
What is the maximum continuous forward current per diode at 100 °C ambient?
At Tamb = 100 °C, the derated forward current per diode is approximately 180 mA, based on the FR4 PCB derating curve in Figure 1. This value assumes single-diode operation on a standard tin-plated copper footprint and accounts for thermal resistance and junction temperature limits up to 150 °C.
Can BAV170M be used in place of a single diode like BAV21?
No - BAV170M is a dual common-cathode device with fixed internal topology; it cannot substitute for a single-diode part without circuit redesign. Its anodes are isolated but share cathode, so using only one anode requires external cathode termination and leaves unused junction parasitics affecting layout and thermal behavior.
Is the 3 pA reverse current guaranteed over temperature?
No - 3 pA is the typical value at 25 °C and 75 V. At 150 °C and 75 V, IR rises to 3–80 nA per the Characteristics table. Designers must verify leakage impact at worst-case operating temperature using the exponential Tj dependence shown in Figure 5.
Does the DFN1006-3 package support automated optical inspection (AOI)?
Yes - the DFN1006-3 package has a transparent top view and clearly defined solder land geometry per Figure 10, enabling reliable AOI detection of solder joint quality, tombstoning, and lateral misalignment in high-volume SMT lines.
