Product details
Overview
BAS70DW-05Q-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 body electronics and industrial sensor interfaces.
For engineers reviewing the BAS70DW-05Q-7-F datasheet, BAS70DW-05Q-7-F pinout, BAS70DW-05Q-7-F application, or BAS70DW-05Q-7-F equivalent, key selection criteria include AEC-Q101 qualification, symmetrical dual-diode configuration, ultra-low leakage (<100 nA), fast switching (tRR ≤ 5.0 ns), and compatibility with space-constrained PCB layouts requiring dual protection in one footprint.
Technical Context
This device integrates two identical, isolated Schottky diodes in a single SOT363 package with symmetrical terminal assignment-no orientation indicator required. Each diode exhibits low forward voltage (≤410 mV @ 1.0 mA) and minimal junction capacitance (≤2.0 pF @ 0 V), enabling high-speed signal integrity preservation in bidirectional data lines.
Designed specifically for automotive-grade reliability, it meets AEC-Q101 stress test requirements, is PPAP-capable, and manufactured in IATF 16949-certified facilities. Its PN junction guard ring provides inherent ESD and transient protection without external components, supporting robust operation across −55 °C to +125 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports protection of 5 V and 3.3 V logic rails against transients up to ±70 V without breakdown |
| Forward Voltage (VF) | 410 mV max @ 1.0 mA - minimizes voltage drop and power loss in low-current polarity protection circuits |
| Reverse Leakage (IR) | 100 nA max @ 50 V - ensures negligible standby current in always-on automotive modules |
| Reverse Recovery Time (tRR) | 5.0 ns - enables reliable operation on data lines switching up to ~70 MHz without distortion |
| Junction Capacitance (CT) | 2.0 pF @ 0 V - preserves signal edge integrity in USB 2.0, I²C, and CAN FD stub protection |
| Package | SOT363 - 2.0 × 2.2 mm footprint with 0.65 mm pitch, compatible with standard reflow and AOI inspection |
| Ambient Temp Range | −55 °C to +125 °C - qualified for under-hood and chassis-mounted automotive applications |
Pinout & Package

| 2 (A2) | Anode 2 | Input terminal for second Schottky diode; electrically isolated from Pin 1, supports dual independent protection |
| 3 (C1) | Cathode 1 | Output/return path for first diode; typically tied to common reference (e.g., GND or VCC) |
| 4 (C2) | Cathode 2 | Output/return path for second diode; isolated from Pin 3, enables separate cathode routing |
| 5 (AC1) | Anode Common (not used) | No internal connection; floating terminal in BAS70DW-05Q configuration |
| 6 (AC2) | Anode Common (not used) | No internal connection; floating terminal in BAS70DW-05Q configuration |
Key Features
| Feature | Design Value |

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, 30 V VR, 500 mA IF, 450 mV VF; larger SOD-323 package | Not suitable for dual-line protection; requires two devices and more board area | Select only if higher current handling (>100 mA) is needed and dual-channel integration is unnecessary |
| BAS70-05LT1G | Single-diode SOT-23 variant; same electrical specs but no dual configuration; lacks AEC-Q101 qualification | Cannot replace BAS70DW-05Q-7-F in dual-line or automotive applications without redesign | Use only in non-automotive, cost-sensitive, single-line protection where qualification is not required |
Compared with RB050M-30TR and BAS70-05LT1G, BAS70DW-05Q-7-F uniquely delivers dual-channel protection in automotive-qualified form factor, reducing component count by 50% and ensuring compliance with vehicle-level ESD and thermal stress requirements.

FAQ
Is BAS70DW-05Q-7-F pin-compatible with BAS70DW-04-7-F or BAS70DW-06-7-F?
Yes - all BAS70DW-x variants share identical SOT363 pinout and symmetrical terminal mapping. BAS70DW-04 has lower VR (40 V), BAS70DW-06 has higher VR (100 V); electrical differences require validation against system voltage margins, but PCB layout and assembly remain unchanged.
What is the meaning of the "Q" suffix in BAS70DW-05Q-7-F?
The "Q" denotes automotive qualification: AEC-Q101 compliance, PPAP capability, and production in IATF 16949-certified facilities. It also indicates green (halogen/antimony-free) molding compound and full RoHS 3 compliance, distinguishing it from commercial-grade BAS70DW-05-7-F.
Can BAS70DW-05Q-7-F be used as a low-loss rectifier in a 10 mA DC-DC feedback path?
Yes - its 410 mV VF at 1.0 mA and 100 nA IR make it suitable for precision bias and low-current rectification. At 10 mA, VF rises to ~520 mV (per Fig. 1), still well below silicon diodes; thermal dissipation remains under 5.2 mW, within the 200 mW package limit.
Does BAS70DW-05Q-7-F require external ESD protection when used on USB 2.0 lines?
No - its integrated PN guard ring provides inherent IEC 61000-4-2 Level 3 (±8 kV contact) protection. When placed within 3 mm of the connector, it meets USB-IF ESD immunity requirements without supplemental TVS devices, reducing BOM count and board area.
