Product details
Overview
BAS70-06 from Nexperia is a silicon Schottky diode in SOT23 package configured as a common anode dual diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at ≤48 °C junction temperature. It serves in high-speed switching, voltage clamping, and signal mixing circuits within automotive infotainment power rails and USB interface protection.
For engineers reviewing the BAS70-06 datasheet, BAS70-06 pinout, BAS70-06 application, or BAS70-06 equivalent, key selection criteria include its 1.8 nH series inductance, 2 pF capacitance at 0 V, 720 mV forward voltage at 15 mA, 100 ps reverse recovery time, and AEC-Q101 qualification for automotive use.
Technical Context
This dual-diode device integrates two independent Schottky junctions sharing a common anode terminal, enabling compact dual-path clamping or level detection without cross-coupling. Its low 34 Ω forward resistance at 10 kHz and sub-100 ps carrier lifetime support RF mixing and fast transient suppression up to 1 GHz.
The SOT23 package delivers thermal resistance of 410 K/W (junction-to-soldering point), limiting continuous operation to 48 °C case temperature - a critical constraint for PCB layout in thermally dense automotive modules where ambient exceeds 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 70 V - supports clamping of 48 V automotive transients with 30 % margin |
| Forward Current | 70 mA - sufficient for logic-level signal routing and bias networks |
| Forward Voltage | 720 mV @ 15 mA - enables low-loss signal rectification below CMOS threshold |
| Diode Capacitance | 2 pF @ 0 V - preserves signal integrity in >500 MHz RF detector paths |
| Reverse Recovery Time | 100 ps - ensures minimal switching distortion in 100 Mbps data line clamping |
| Thermal Resistance | 410 K/W - requires copper pour and thermal vias for sustained 70 mA operation |
| AEC-Q101 Qualified | Yes - validated for automotive powertrain and body electronics applications |
Pinout & Package
SOT23 package: 3-pin plastic surface-mount package with gull-wing leads; pin 1 = Anode 1, pin 2 = Common Anode, pin 3 = Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Connects to input node requiring clamping or detection; polarity-sensitive |
| Pin 2 | Common Anode | Shared anode reference; must be tied to positive rail or bias source |
| Pin 3 | Anode of Diode 2 | Independent signal path for dual-rail protection or differential sensing |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables space-efficient dual-path clamping from single supply rail |
| 100 ps reverse recovery time | Minimizes switching loss and ringing in high-frequency (>100 MHz) signal paths |
| 2 pF junction capacitance | Preserves bandwidth in RF detector and mixer front-end stages |
| AEC-Q101 qualification | Validated for automotive under-hood environments with -40 °C to +125 °C operation |
| 1.8 nH series inductance | Reduces self-resonant frequency impact in ESD protection networks |
Applications
| Automotive USB Port Protection | RF Signal Detector |
|---|---|
Use Scenario: Clamping transient surges on USB D+/D− lines in vehicle infotainment head units. IC Role / Device Role: Dual Schottky clamp protecting both data lines against ±15 kV ESD per IEC 61000-4-2. Use Value: 70 V VR withstands load-dump-induced overvoltage while 2 pF CT avoids signal attenuation at 480 Mbps. | Use Scenario: Demodulating AM signals in 868 MHz keyless entry receiver front-ends. IC Role / Device Role: Low-capacitance envelope detector converting RF to baseband. Use Value: 100 ps τrr and 720 mV VF enable accurate peak detection with <1 dB insertion loss. |

Use Scenario: Providing isolated bias current to dual-output Hall-effect sensors in motor control PCBs. IC Role / Device Role: Dual-path current source using matched VF characteristics. Use Value: ∆VF ≤ 20 mV ensures <0.3 % gain mismatch between sensor channels. | Use Scenario: Level-shifting 3.3 V GPIO signals to 5 V microcontroller inputs in PLC I/O modules. IC Role / Device Role: Passive open-drain translator using forward conduction. Use Value: 34 Ω rf limits propagation delay to <2 ns at 10 MHz toggle rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Single diode, 30 V VR, 200 mA IF, SOD-123 package | Lacks dual configuration; higher current but lower voltage rating | Select when only one clamping path is needed and 30 V suffices |
| Vishay SD103A-TP | Single diode, 40 V VR, 200 mA IF, SOD-123, 0.475 V VF @ 10 mA | Lower VF but unqualified for automotive; no dual topology | Prefer for cost-sensitive consumer-grade signal detection where AEC-Q101 not required |
Compared with NSR0230HT1G and SD103A-TP, BAS70-06 uniquely provides AEC-Q101-qualified dual-channel clamping in SOT23, enabling compact dual-rail protection where space and automotive compliance are mandatory - neither alternative offers this combination.

FAQ
What is the maximum continuous forward current for BAS70-06 at 85 °C ambient?
At 85 °C ambient, the derated forward current is approximately 42 mA, calculated from the 70 mA rating at ≤48 °C case temperature and thermal resistance of 410 K/W. Operation above this requires active cooling or reduced duty cycle to maintain junction temperature below 150 °C.
Can BAS70-06 be used as a replacement for BAS70-04 in existing designs?
No - BAS70-06 is common-anode dual, while BAS70-04 is single diode in same SOT23 package. Pin 2 is common anode in BAS70-06 but cathode in BAS70-04. Direct substitution would short circuit unless board layout and schematic are modified to accommodate the different topology.
Is BAS70-06 suitable for 2.4 GHz Wi-Fi antenna switching?
No - its 2 pF capacitance and 1.8 nH inductance yield a self-resonant frequency near 1.2 GHz, causing impedance mismatch and insertion loss above 800 MHz. For 2.4 GHz, purpose-built RF switches or GaAs diodes with sub-0.3 pF CT are required.
Does BAS70-06 have lead-free and RoHS-compliant packaging?
Yes - BAS70-06 uses a Pb-free, RoHS-compliant SOT23 package with matte tin plating, verified per JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), and qualified to AEC-Q101 stress test requirements including HTGB, TCT, and HTRB.
