Product details
Overview
BAS70DW-04-7-F from Diodes Incorporated is a dual common-cathode 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 lines in automotive and industrial control interfaces.
For engineers reviewing the BAS70DW-04-7-F datasheet, BAS70DW-04-7-F pinout, BAS70DW-04-7-F application, or BAS70DW-04-7-F equivalent, key selection criteria include low-leakage dual-channel configuration, AEC-Q101 qualification, symmetrical SOT363 layout, and fast switching for ESD-sensitive I/O protection circuits.
Technical Context
This device integrates two identical Schottky diodes sharing a common cathode terminal, enabling bidirectional clamping of differential or complementary signal pairs without polarity constraints. Its ultra-low VF (410 mV @ 1 mA) and sub-100 nA IR minimize power loss and signal distortion in low-current sensing and logic-level translation paths.
The symmetrical SOT363 footprint supports high-density PCB layouts with matched thermal and electrical paths for both channels. Built-in PN junction guard ring provides transient suppression per IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact), making it suitable for unshielded front-end interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 70 V - Blocks up to 70 V reverse bias without breakdown, sufficient for 48 V automotive supply rails and industrial 24 V systems. |
| IF Continuous | 70 mA - Supports sustained current handling for signal conditioning and low-power rectification in sensor interfaces. |
| VF Max @ 1.0 mA | 410 mV - Enables minimal voltage drop across protection path, preserving logic high margin in 1.8 V/3.3 V I/O domains. |
| IR Max @ 50 V | 100 nA - Ensures negligible leakage-induced offset in precision analog monitoring and battery-backed circuits. |
| tRR | 5.0 ns - Allows clean switching in >100 MHz digital signal paths, preventing data corruption during fast edge transitions. |
| CT @ 0 V | 2.0 pF - Limits capacitive loading on high-speed lines, maintaining signal integrity in USB 2.0, I²C, and SPI bus protection. |
| Package | SOT363 - 6-pin, 2.0 × 2.2 mm surface-mount package with 0.65 mm pin pitch, compatible with standard reflow profiles. |
Pinout & Package
SOT363 package: 6-pin, symmetrical, no orientation indicator; molded plastic body (UL 94V-0), matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of Diode A | Accepts positive transient or overvoltage on first protected signal line (e.g., CAN_H or UART_TX). |
| Pin 2 (Anode B) | Anode of Diode B | Accepts positive transient or overvoltage on second protected signal line (e.g., CAN_L or UART_RX). |
| Pin 3 (Cathode) | Common Cathode | Connected to system ground or clamp rail; sinks surge current from both anodes simultaneously. |
| Pin 4 (NC) | No Connect | Internally unconnected; must remain floating-no PCB trace or solder mask opening required. |
| Pin 5 (Cathode) | Common Cathode (Redundant) | Electrically tied to Pin 3; used for mechanical stability and thermal dissipation in high-reliability layouts. |
| Pin 6 (Anode A) | Anode of Diode A (Redundant) | Electrically tied to Pin 1; provides second bonding point for improved current sharing and bond-wire reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Low Forward Voltage Drop | 410 mV max at 1.0 mA enables efficient clamping without degrading logic-high thresholds in 1.8–3.3 V systems. |
| Fast Switching Speed | 5.0 ns reverse recovery time ensures minimal distortion on signals up to 100 MHz, critical for high-speed serial links. |
| PN Junction Guard Ring | Integrated guard ring structure suppresses ESD-induced latch-up and improves robustness to ±8 kV contact discharge events. |
| AEC-Q101 Qualified | Validated for automotive underhood and infotainment applications with full temperature range (-55°C to +125°C) operation. |
| Ultra-Small SOT363 Footprint | 2.0 × 2.2 mm area saves >40% board space vs. discrete dual-diode solutions, easing routing in tight connector zones. |
Applications

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 |
|---|---|---|---|
| DMN2004LKQ-7 | Single-channel, 20 V VRRM, 200 mA IF, SOT23 package | Not dual-channel; requires two devices for same function; lower voltage rating limits use in 24 V+ systems | Select only when single-line protection suffices and board space allows duplication. |
| BAT54CDW-7-F | Same SOT363 package, 30 V VRRM, 200 mA IF, 450 mV VF @ 10 mA | Lower reverse voltage rating; higher forward drop reduces margin in low-voltage logic interfaces | Preferable only for cost-sensitive 3.3 V-only designs where 30 V blocking is sufficient. |
Compared with DMN2004LKQ-7 and BAT54CDW-7-F, BAS70DW-04-7-F uniquely delivers 70 V blocking, 410 mV low VF at 1 mA, and AEC-Q101 qualification in a single dual-channel SOT363-making it optimal for automotive and industrial signal-line protection where voltage headroom and leakage performance are critical.

FAQ
Is BAS70DW-04-7-F pin-compatible with BAS70DW-05-7-F?
No. BAS70DW-04-7-F uses a dual common-cathode configuration (Pins 1 & 2 = anodes, Pins 3 & 5 = common cathode), while BAS70DW-05-7-F is dual common-anode (Pins 1 & 2 = cathodes, Pin 3 = common anode). Layout redesign is required for substitution.
What is the maximum operating temperature for continuous use?
The device is rated for continuous operation from –55°C to +125°C ambient temperature. Derating begins above +25°C per Figure 4: at +125°C, maximum power dissipation drops to 80 mW (40% of 200 mW rating at 25°C).
Does BAS70DW-04-7-F meet RoHS and halogen-free requirements?
Yes. It is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes' definition: <900 ppm Br, <900 ppm Cl, <1000 ppm Sb), with UL 94V-0 mold compound.
Can this part be used in place of discrete 1N5711 diodes?
No. While both are Schottky diodes, 1N5711 is a single 70 V, 150 mA axial-leaded device with VF ≈ 1.0 V @ 15 mA. BAS70DW-04-7-F offers dual-channel integration, 410 mV VF @ 1 mA, SOT363 surface-mount packaging, and AEC-Q101 qualification-functionally distinct and not a drop-in replacement.
