Product details
Overview
BAS70-06W-Q from Nexperia is a general-purpose dual Schottky diode in SOT323 (SC-70) package, featuring common-anode configuration, 70 V reverse voltage rating, 70 mA forward current capability, and 410 mV typical forward voltage at 1 mA - optimized for ultra-high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS70-06W-Q datasheet, BAS70-06W-Q pinout, BAS70-06W-Q application, or BAS70-06W-Q equivalent, key selection criteria include its AEC-Q101 qualification, low 2 pF capacitance at 0 V, 100 nA reverse leakage at 50 V, and thermal resistance of 500 K/W - critical for compact, thermally constrained automotive PCB layouts.
Technical Context
This dual Schottky diode integrates two independent diodes sharing a common anode terminal (Pin 3), enabling bidirectional clamping or dual-path rectification in a single 2.0 mm × 1.25 mm footprint. Its low forward voltage and fast recovery support high-frequency transient suppression without minority-carrier storage delay.
The device operates across −65 °C to +150 °C ambient range with junction temperature limited to 150 °C, and exhibits stable reverse leakage (<10 µA at 70 V, 25 °C) and minimal capacitance variation (2 pF at 0 V, 1 MHz), making it suitable for ESD-sensitive analog front-ends and CAN/LIN bus protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transients up to ISO 7637-2 Pulse 1/2a in 12 V automotive systems |
| Forward Voltage (VF) | 410 mV at 1 mA - minimizes conduction loss in low-current bias and sensing paths |
| Reverse Leakage (IR) | 100 nA at 50 V, 25 °C - ensures negligible standby current in always-on monitoring circuits |
| Diode Capacitance (Cd) | 2 pF at 0 V, 1 MHz - preserves signal integrity in >100 MHz RF-coupled or high-speed data lines |
| Thermal Resistance (Rth(j-a)) | 500 K/W - defines power derating on standard FR4 PCBs with single-sided copper |
| Peak Forward Current (IFSM) | 100 mA at 10 ms - withstands short-duration surge events like load dump-induced spikes |
Pinout & Package
Package: SOT323 (SC-70), 3-terminal surface-mount plastic package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides dedicated cathode path for first Schottky junction; routed separately for asymmetric clamping |
| 2 | Cathode (Diode 2) | Independent cathode for second junction; enables dual-rail or differential clamping topologies |
| 3 | Common Anode | Shared anode connection simplifies PCB layout for bidirectional protection or dual-sensing configurations |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications per stress test requirements including HTGB, HTRB, and TCT |
| Low forward voltage | 410 mV typ. at 1 mA enables efficient biasing in low-power sensor interfaces without voltage headroom loss |
| High-speed switching | No minority-carrier storage; sub-nanosecond recovery supports >1 GHz transient response in ESD protection networks |
| Low leakage & capacitance | 100 nA IR and 2 pF Cd maintain accuracy in precision voltage reference and ADC input protection circuits |
Applications
| Automotive LIN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protects LIN transceiver I/O pins against ESD and load-dump induced voltage spikes in body control modules. IC Role / Device Role / Timing Role: Dual-cathode Schottky clamps bidirectional LIN signals to VCC and GND rails using common-anode topology. Use Value: 70 V VR and 2 pF capacitance prevent signal distortion while meeting ISO 10605 ±25 kV ESD immunity. |
Use Scenario: Shields USB 2.0 D+ and D− lines from electrostatic discharge during hot-plug events in infotainment head units. IC Role / Device Role / Timing Role: Each cathode connects to one data line; common anode ties to 3.3 V rail for low-clamp-voltage protection. Use Value: 410 mV VF ensures clamping threshold stays below USB eye diagram margin, preserving signal integrity. |
| Automotive Sensor Signal Conditioning | Low-Power IoT Node Voltage Clamp |
Use Scenario: Clamps output of analog pressure or temperature sensors exposed to battery transients in engine management systems. IC Role / Device Role / Timing Role: Dual diodes route sensor output and supply rail transients to common reference, minimizing offset drift. Use Value: 100 nA IR at 25 °C avoids loading microamp-level sensor outputs, preserving measurement accuracy. |
Use Scenario: Provides overvoltage protection for coin-cell-powered BLE/Wi-Fi sensor nodes operating in industrial environments. IC Role / Device Role / Timing Role: Common-anode configuration allows single-device bidirectional clamping between VDD and GND for supply rail stabilization. Use Value: 500 K/W Rth(j-a) enables operation at full rating without heatsinking in space-constrained 0402-class footprints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F70HT1G | Higher VF (550 mV typ. at 1 mA); same 70 V VR and SOT-323 package | Less suitable for ultra-low-voltage signal paths due to higher conduction loss | Select when higher surge robustness (IFSM = 200 mA) outweighs VF penalty |
| Diodes Inc. BAV99WQ-7-F | Lower VR (35 V); AEC-Q101 qualified; same common-anode SOT-323 | Restricted to 5 V or 3.3 V systems; unsuitable for 12 V automotive transients | Prefer for cost-sensitive consumer-grade 5 V interfaces where 70 V rating is unnecessary |
Compared with NSR20F70HT1G and BAV99WQ-7-F, BAS70-06W-Q uniquely balances 70 V standoff, 410 mV VF, and 2 pF capacitance - making it the only option among the three qualified for 12 V automotive clamping without compromising high-speed signal fidelity.

FAQ
Is BAS70-06W-Q suitable for bidirectional ESD protection on a single-ended analog signal line?
Yes. With its common-anode configuration, BAS70-06W-Q can clamp positive transients to VCC via one diode and negative transients to GND via the other, enabling effective bidirectional protection without external resistors or additional components - confirmed by Nexperia's application note AN11124 for analog I/O protection.
What is the maximum allowable PCB trace length between BAS70-06W-Q and the protected IC pin?
For optimal ESD performance, keep the trace from the protected pin to BAS70-06W-Q cathode ≤2 mm, and from common anode to VCC/GND plane ≤3 mm. Longer traces increase inductance, degrading clamping speed - validated in Nexperia's layout guidelines for SC-70 devices in AN10717.
Does BAS70-06W-Q require derating at 85 °C ambient temperature?
Yes. At Tamb = 85 °C, the maximum continuous forward current must be reduced to 42 mA (per Figure 1 in datasheet), based on thermal resistance of 500 K/W and 150 °C max junction temperature - exceeding this risks accelerated parametric shift and reliability degradation.
Can BAS70-06W-Q replace BAS70-05W-Q in existing designs?
No. BAS70-05W-Q has a common-cathode configuration (anodes on Pins 1 & 2, cathode on Pin 3), whereas BAS70-06W-Q uses common-anode (cathodes on Pins 1 & 2, anode on Pin 3). Swapping them without schematic and layout revision will invert clamping polarity and cause functional failure.
