Product details
Overview
BAS70DW-06-7-F 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, 410 mV max forward voltage at 1.0 mA, 100 nA max reverse leakage at 50 V, and 5.0 ns reverse recovery time. 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-F datasheet, BAS70DW-06-7-F pinout, BAS70DW-06-7-F application, or BAS70DW-06-7-F equivalent, key selection criteria include low-leakage dual-diode configuration, AEC-Q101 qualification, symmetrical SOT363 terminal layout, and suitability for high-speed polarity protection in space-constrained PCBs.
Technical Context
This device integrates two identical, isolated Schottky diodes in a single symmetrical SOT363 package with no orientation indicator. Each diode exhibits ultra-low forward voltage (≤410 mV @ 1.0 mA) and fast switching (tRR ≤ 5.0 ns), enabling efficient clamping and signal steering without cross-talk.
Designed to meet AEC-Q101 requirements, it features a PN junction guard ring for ESD and transient protection, operates across –55°C to +125°C, and delivers 200 mW power dissipation on FR-4 with standard pad layout. Its 2.0 pF capacitance at 0 V supports high-frequency data line integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (DC Blocking) | 70 V - Supports protection of 3.3 V/5 V/12 V rails against reverse polarity up to automotive battery transients. |
| VF max @ 1.0 mA | 410 mV - Minimizes voltage drop and power loss in low-current signal path clamping. |
| IR max @ 50 V | 100 nA - Ensures minimal leakage-induced offset error in precision analog or sensor interfaces. |
| tRR | 5.0 ns - Enables reliable operation in >10 MHz digital signal lines and multiplexed bus applications. |
| CT @ 0 V | 2.0 pF - Preserves signal integrity on USB, I²C, and CAN FD data lines without added jitter. |
| PD | 200 mW - Allows continuous operation at full rating with standard SOT363 thermal pad layout on FR-4. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.0 × 2.225 × 0.9 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| USB Data Line Protection | Automotive Sensor Interface |
|---|---|
Use Scenario: Bidirectional 5 V USB 2.0 D+/D− lines exposed to hot-plug and ESD events in telematics control units. IC Role / Device Role / Timing Role: Dual-rail clamp - each diode steers transient current from D+ or D− to VBUS or GND while preserving signal rise/fall times. Use Value: 2.0 pF capacitance and 5 ns tRR prevent signal distortion; 410 mV VF avoids false logic-low detection during normal operation. | Use Scenario: Analog output lines from pressure or temperature sensors in engine control modules subject to load dump and reverse battery conditions. IC Role / Device Role / Timing Role: Polarity protection + overvoltage clamp - anodes connect to sensor outputs, cathodes tie to regulated 5 V rail. Use Value: 100 nA IR prevents sensor output loading; 70 V VR withstands ISO 7637-2 Pulse 5a transients without breakdown. |
| Industrial I²C Bus Buffering | Low-Power Multiplexer Steering |
Use Scenario: Level-shifting I²C buses between 3.3 V microcontrollers and 5 V peripherals in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional signal conditioner - diodes conduct only during voltage differentials exceeding VF, enabling passive level translation. Use Value: Matched VF ensures symmetric high/low threshold shift; low CT maintains 400 kHz timing margins across 20 cm traces. | Use Scenario: Selecting between two analog sensor inputs using GPIO-controlled enable signals in portable medical devices. IC Role / Device Role / Timing Role: Low-leakage signal path selector - diodes act as OR-gated switches with anodes driven by microcontroller pins. Use Value: 100 nA IR prevents crosstalk between inactive channels; 410 mV VF enables clean turn-on below 1.8 V logic thresholds. |
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 |
|---|---|---|---|
| SBAT54DW-7-F | Higher VF (max 500 mV @ 10 mA), same 70 V VR, 3.0 pF CT, non-AEC-Q101. | Not qualified for automotive use; higher capacitance limits >10 MHz data rates. | Select when cost sensitivity outweighs AEC-Q101 compliance and high-speed performance. |
| BAS70-06LT1G | Single-diode SOT-23 variant; identical electrical specs but requires two placements for dual function. | Increases PCB area and assembly cost; lacks integrated symmetry and thermal coupling benefits. | Choose only if SOT-23 footprint is mandated and board space permits duplication. |
Compared with SBAT54DW-7-F and BAS70-06LT1G, the BAS70DW-06-7-F uniquely combines AEC-Q101 qualification, symmetrical dual-diode integration in SOT363, and 2.0 pF capacitance-making it optimal for space-constrained automotive and industrial signal protection where reliability and signal fidelity are co-prioritized.

FAQ
Is BAS70DW-06-7-F 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-05 ties both cathodes internally (common-cathode), while BAS70DW-06 leaves cathodes independent (dual-anode/dual-cathode). Pin numbering and physical layout are identical; only schematic symbol and net connectivity differ.
What is the maximum operating temperature for continuous use?
The device is rated for continuous operation from –55°C to +125°C junction temperature. At ambient temperatures up to +85°C with standard FR-4 mounting and recommended pad layout, it sustains full 200 mW power dissipation. Derating begins above 85°C ambient per Fig. 4 in DS30158 Rev. 15–2, reaching zero dissipation at +125°C.
Does BAS70DW-06-7-F require external ESD protection?
No - it integrates a PN junction guard ring that provides inherent ESD robustness (HBM ≥ 8 kV per Diodes' quality documentation), making it suitable as a standalone protection element for I/O lines in AEC-Q101-compliant designs without supplemental TVS diodes in most cases.
Can this part be used in reverse-biased Zener-like clamping configurations?
No - the BAS70DW-06-06 is a Schottky diode array with no controlled reverse breakdown characteristic. Its specified reverse breakdown voltage is 70 V minimum, but it is not designed or characterized for stable Zener operation. For precision clamping above forward conduction, a dedicated TVS or Zener diode is required.
