Product details
Overview
BAS70DW-06-7 from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, rated for 70 V reverse voltage, 1.0 mA forward current, 0.41 V max forward voltage at +25°C, and 0.10 µA max reverse leakage at +25°C. It serves as rail-to-rail data line protection for two independent signal paths in automotive and industrial interface circuits.
For engineers reviewing the BAS70DW-06-7 datasheet, BAS70DW-06-7 pinout, BAS70DW-06-7 application, or BAS70DW-06-7 equivalent, key selection criteria include low-leakage dual-diode configuration, AEC-Q101 qualification, ultra-small SOT363 footprint, fast 5.0 ns reverse recovery time, and suitability for polarity protection and multiplexing circuits.
Technical Context
This device integrates two matched Schottky diodes in a symmetrical, orientation-free SOT363 package with PN junction guard rings for ESD and transient robustness. Its 70 V VR rating and sub-1 µA IR enable reliable operation in 24 V automotive rails and low-power sensor interfaces.
The 5.0 ns tRR, 2.0 pF CT at 0 V, and 0.41 V VF @ 1.0 mA support high-speed signal clamping and low-loss rectification in space-constrained, low-current bridge or recirculation applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 70 V - supports 24 V automotive supply rails with margin against transients |
| VF (Max) | 0.41 V @ 1.0 mA - minimizes forward power loss in low-current protection paths |
| IR (Max) | 0.10 µA @ 50 V - ensures signal integrity in high-impedance data lines |
| tRR | 5.0 ns - enables use in >10 MHz digital line protection without timing skew |
| CT | 2.0 pF @ 0 V - preserves bandwidth in USB, I²C, or CAN FD data line clamping |
| PD | 200 mW - defines thermal limit on FR-4 PCB with standard pad layout |
| TJ Range | –55°C to +125°C - meets extended temperature requirements for under-hood automotive modules |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.0 × 2.225 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of Diode 1 | Input terminal for first protected signal path; connects to source side of polarity or clamp circuit |
| Pin 2 (A2) | Anode of Diode 2 | Input terminal for second independent signal path; enables dual-line rail-to-rail protection |
| Pin 3 (C1) | Cathode of Diode 1 | Output/return node for Diode 1; ties to common reference (e.g., VCC or GND) in clamp configuration |
| Pin 4 (C2) | Cathode of Diode 2 | Output/return node for Diode 2; allows independent cathode routing for asymmetric protection schemes |
| Pin 5 (E1) | Exposed pad / thermal slug | Not electrically connected; provides mechanical stability and minor thermal relief when soldered to copper pour |
| Pin 6 (E2) | Exposed pad / thermal slug | Not electrically connected; matches Pin 5 for symmetric board assembly and reflow profile control |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.41 V max @ 1.0 mA - reduces voltage offset and self-heating in precision analog front-ends |
| Fast switching speed | 5.0 ns reverse recovery - prevents signal distortion during high-frequency data line transients |
| PN junction guard ring | Integrated ESD protection per IEC 61000-4-2 Level 4 (±15 kV air) - eliminates need for external TVS in many Class B designs |
| AEC-Q101 qualified | Qualified for automotive applications - enables direct use in infotainment, body control, and ADAS sensor interfaces without additional qualification |
| Ultra-small SOT363 footprint | 2.0 × 2.225 mm outline - saves >60% board area vs. discrete SOD-323 diodes for dual-channel protection |
Applications
| USB 2.0 Data Line Protection | Automotive LIN Bus Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD and overvoltage events in portable docking stations and embedded host controllers. IC Role / Device Role / Timing Role: Dual-channel bidirectional clamp diode array providing rail-to-rail voltage limiting between VDD and GND. Use Value: 2.0 pF capacitance preserves USB 2.0 full-speed (12 Mbps) signal integrity; 5.0 ns tRR avoids data corruption during hot-plug transients. | Use Scenario: Polarity reversal and load-dump protection for LIN transceivers in door modules and seat control units. IC Role / Device Role / Timing Role: Dual anode-cathode pair configured as back-to-back series diodes across LIN bus and local supply. Use Value: 70 V VR withstands ISO 7637-2 pulse 1 (–100 V) and pulse 3a/b; 0.10 µA IR prevents battery drain in always-on nodes. |
| Industrial Sensor Signal Conditioning | Low-Power Multiplexer Output Clamping |
Use Scenario: Protecting analog outputs of RTD or thermocouple signal conditioners from field wiring faults and EMI coupling. IC Role / Device Role / Timing Role: Dual Schottky clamp placed between output buffer and connector, referenced to system rails. Use Value: 0.41 V VF ensures <1 mV offset error at 2.5 V full-scale; –55°C to +125°C operation supports unheated outdoor enclosures. | Use Scenario: Preventing voltage overshoot at multiplexer output pins during channel switching in battery-powered data loggers. IC Role / Device Role / Timing Role: Two independent Schottky diodes clamping each MUX output to VCC and GND respectively. Use Value: Symmetrical SOT363 pinout (BAS70DW-06) allows identical PCB layout for both channels; 100 nA IR avoids loading high-Z analog outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Single-channel SOD-523; 30 V VR, 0.39 V VF @ 10 mA; no AEC-Q101 qualification | Requires two devices for dual-path protection; unsuitable for 24 V automotive rails | Select only for cost-sensitive, non-automotive 3.3 V/5 V logic-level clamping where space permits discrete placement |
| BAT54CDW-7-F | Dual SOT363 Schottky; 30 V VR, 0.24 V VF @ 10 mA; AEC-Q101 qualified; higher leakage (1 µA) | Limited to ≤12 V systems; lower VF benefits high-current recirculation but increases leakage risk in high-Z sensors | Prefer for 5 V/12 V consumer IoT gateways needing lowest possible forward drop; avoid in 24 V rail protection or precision analog paths |
Compared with RB050M-30TR and BAT54CDW-7-F, BAS70DW-06-7 uniquely balances 70 V blocking, ultra-low leakage (<0.1 µA), and AEC-Q101 compliance in a single SOT363 package-making it the only option for dual-channel 24 V automotive data line protection without performance trade-offs.

FAQ
Is BAS70DW-06-7 pin-compatible with BAS70DW-05-7-F?
Yes - both share identical SOT363 pinout and symmetrical dual-diode configuration. The difference lies in internal connection: BAS70DW-06 has independent anodes and cathodes (A1/C1 + A2/C2), while BAS70DW-05 ties both cathodes together (A1/C + A2/C). This makes BAS70DW-06 suitable for fully isolated dual-path clamping, whereas BAS70DW-05 is optimized for common-cathode rail clamping.
What is the maximum continuous forward current per diode in BAS70DW-06-7?
The datasheet specifies 70 mA maximum continuous forward current (IFM) per diode at +25°C ambient, derated linearly to zero at +125°C per the 200 mW power dissipation limit and 625°C/W junction-to-ambient thermal resistance. At 85°C ambient, usable IF drops to approximately 45 mA per diode.
Does BAS70DW-06-7 require special PCB layout considerations for thermal performance?
No special layout is required beyond Diodes' recommended SOT363 pad dimensions (C = 0.65 mm, G = 1.30 mm, X = 0.42 mm, Y = 0.60 mm, Y1 = 2.50 mm). The exposed pads (Pins 5 and 6) are non-functional but improve solder joint reliability; connecting them to a small thermal copper pour enhances reflow yield without affecting electrical performance.
Can BAS70DW-06-7 be used in place of a single BAS70-06 discrete diode?
No - BAS70DW-06-7 contains two independent Schottky diodes in one package, while BAS70-06 is a single-diode SOT23 device. Substituting requires redesigning the PCB footprint and verifying that dual-diode functionality (e.g., separate anode/cathode routing) aligns with the target circuit's protection architecture; it is not a drop-in replacement for single-diode applications.
