Product details
Overview
BAS70DW-05-7-F from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, configured as two independent anode-common diodes (A1–C1, A2–C2), with 70 V reverse voltage rating, 1.0 mA forward current capability, 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 high-speed interfaces in automotive infotainment and industrial sensor nodes.
For engineers reviewing the BAS70DW-05-7-F datasheet, BAS70DW-05-7-F pinout, BAS70DW-05-7-F application, or BAS70DW-05-7-F equivalent, key selection criteria include low-leakage dual-diode topology, AEC-Q101 qualification, symmetrical SOT363 pinout, and sub-0.5 V forward drop at microamp-level bias - critical for low-power signal clamping and polarity protection in space-constrained designs.
Technical Context
This device implements two independent Schottky junctions sharing a common anode terminal per channel (A1/C1 and A2/C2), enabling bidirectional clamping or dual-line protection without external interconnect. Its ultra-low IR (≤100 nA @ 50 V) and fast tRR (≤5.0 ns) support high-frequency transient suppression in USB 2.0 and I²C bus lines.
The symmetrical SOT363 layout eliminates orientation dependency, and the PN guard ring structure provides ESD robustness per IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact). Thermal resistance of 625°C/W enables operation up to +125°C ambient in unforced-air environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - supports DC blocking in 48 V automotive subsystems and 24 V industrial control rails |
| IF (mA) | 1.0 mA - rated continuous forward current per diode, suitable for signal-level clamping |
| VF MAX (V) | 0.41 V @ 1.0 mA - minimizes voltage offset in precision analog front-ends and logic-level translation |
| IR MAX (µA) | 0.10 µA @ +25°C - ensures <100 nA leakage at 50 V, critical for battery-backed real-time clocks |
| tRR (ns) | 5.0 ns - enables clean switching in >10 MHz digital signal paths without ringing |
| CT (pF) | 2.0 pF @ 0 V - preserves signal integrity on high-speed differential pairs (e.g., RS-485, CAN FD) |
| Package | SOT363 - 2.0 × 2.2 mm footprint, compatible with standard 0.65 mm pitch reflow profiles |

IC Role / Device Role / Timing Role: Low-capacitance (2.0 pF) dual clamp preventing op-amp saturation during fault conditions. Use Value: Maintains THD <−100 dB at 10 kHz while adding <0.5 mV offset error due to 0.41 V VF asymmetry. |
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 |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel, 20 V VR, 1.2 A IF, SOT-23 - higher current but lower voltage rating | Not suitable for 48 V rail protection; limited to 3.3/5 V logic domains | Select only when >100 mA forward surge handling is required and VR ≤20 V suffices |
| BAT54CDW-7-F | Dual Schottky, 30 V VR, 200 mA IF, same SOT363 package, VF = 0.33 V @ 10 mA | Higher IF rating but insufficient for 48 V systems; lacks AEC-Q101 qualification | Prefer for non-automotive consumer electronics where cost is prioritized over automotive reliability |
Compared with DMN2016LFG-7 and BAT54CDW-7-F, BAS70DW-05-7-F uniquely balances 70 V blocking, AEC-Q101 compliance, and 100 nA leakage - making it the only option qualified for automotive signal line protection where both voltage margin and low-power standby integrity are mandatory.

FAQ
What is the maximum reverse voltage rating for BAS70DW-05-7-F?
The maximum repetitive reverse voltage (VRRM) is 70 V, verified per DS30158 Rev. 15–2 test conditions at TA = +25°C. This rating remains valid across the full −55°C to +125°C operating range, with derating applied above +125°C per Figure 4's power derating curve.
Is BAS70DW-05-7-F qualified for automotive use?
Yes - it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The "Q" suffix variant (BAS70DW-05Q-7-F) adds formal change control documentation, but the -7-F version shares identical die, assembly, and qualification data per Diodes' product definitions page.
How does the SOT363 pinout differ between BAS70DW-05-7-F and BAS70DW-04-7-F?
BAS70DW-05-7-F uses symmetrical anode-common configuration (A1/C1 and A2/C2), whereas BAS70DW-04-7-F is cathode-common (C1/A1 and C2/A2). Pin 1 is A1 in DW-05 and C1 in DW-04 - this inversion affects PCB layout and cannot be interchanged without schematic revision.
Can BAS70DW-05-7-F replace BAT54CDW-7-F in existing designs?
Only after verifying 70 V blocking margin and leakage requirements: BAT54CDW-7-F has 30 V VR and 500 nA IR at 25 V, while BAS70DW-05-7-F delivers 70 V VR and 100 nA IR at 50 V. Layout compatibility exists (same SOT363 footprint), but electrical validation is mandatory due to different forward conduction characteristics and thermal limits.
