Product details
Overview
BAS70TWQ-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, 0.41 V max forward voltage at +25°C, 0.10 µA max reverse leakage at +25°C, and 5.0 ns reverse recovery time. It serves as polarity protection and rail-to-rail data line protection in automotive and industrial signal conditioning circuits.
For engineers reviewing the BAS70TWQ-7-F datasheet, BAS70TWQ-7-F pinout, BAS70TWQ-7-F application, or BAS70TWQ-7-F equivalent, key selection criteria include low-leakage dual-diode configuration, AEC-Q101 qualification, ultra-small SOT363 footprint, fast switching performance, and suitability for low-current bridge rectification and ESD-protected multiplexing.
Technical Context
This device integrates two independent Schottky diodes in a single symmetrical SOT363 package with no orientation indicator. Each diode features a PN junction guard ring for transient and ESD protection, enabling robust operation in noisy automotive environments.
It operates across –55°C to +125°C, supports 70 V peak repetitive reverse voltage, delivers 0.41 V forward voltage at 1.0 mA, and exhibits only 100 nA reverse current at 50 V - critical for battery-powered and low-power sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - maximum DC blocking voltage per diode; defines safe operating range in polarity protection and clamping applications |
| IF (mA) | 1.0 mA - rated continuous forward current; suitable for low-power signal routing and bias networks |
| VF MAX (V) @ +25°C | 0.41 V - low forward drop ensures minimal voltage loss in power path or logic-level translation |
| IR MAX (µA) @ +25°C | 0.10 µA - ultra-low leakage preserves battery life and signal integrity in high-impedance circuits |
| tRR (ns) | 5.0 ns - fast recovery enables use in high-frequency switching and data-line protection up to ~100 MHz |
| CT (pF) | 2.0 pF @ 0 V - low junction capacitance minimizes signal distortion in high-speed analog or digital I/O lines |
| Package | SOT363 - 6-pin, symmetrical surface-mount package; occupies <1.3 mm² PCB area and supports automated assembly |
Pinout & Package
Package: SOT363 - ultra-small plastic molded 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 |
|---|---|---|
| Pin 1 (A1) | Anode of Diode 1 | Input terminal for first Schottky diode; connects to protected source or signal line |
| Pin 2 (A2) | Anode of Diode 2 | Input terminal for second independent Schottky diode; enables dual-path protection |
| Pin 3 (C1) | Cathode of Diode 1 | Output/return path for Diode 1; ties to common rail or ground reference |
| Pin 4 (C2) | Cathode of Diode 2 | Output/return path for Diode 2; electrically isolated from C1 for independent channel routing |
| Pins 5 & 6 (AC1, AC2) | Common anode connection (not used) | Unused terminals in BAS70TW configuration; left unconnected per datasheet marking diagram |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.41 V max at 1.0 mA - reduces conduction loss in low-voltage power rails and battery-fed systems |
| Fast switching speed | 5.0 ns reverse recovery - enables reliable protection of high-speed serial interfaces (e.g., CAN FD, LIN, I²C) |
| PN junction guard ring | Integrated ESD and transient suppression - meets IEC 61000-4-2 Level 4 (±15 kV air) without external components |
| AEC-Q101 qualification | Qualified for automotive-grade reliability - validated for temperature cycling, HTRB, and mechanical shock per JESD22 standards |
| Ultra-small SOT363 footprint | 2.0 × 2.225 mm outline - saves >60% board space vs. discrete SOD-323 diodes for dual-channel designs |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Interface Board |
|---|---|
|
Use Scenario: Protecting LIN bus transceiver inputs against reverse battery connection and load dump transients. IC Role / Device Role / Timing Role: Dual-channel polarity and overvoltage clamp; each diode independently routes supply and signal paths. Use Value: Eliminates need for two discrete SOD-323 diodes, reducing BOM count and PCB area while maintaining AEC-Q101 compliance. |
Use Scenario: Rail-to-rail clamping of analog sensor outputs (e.g., thermistor, RTD) before ADC input stages. IC Role / Device Role / Timing Role: Low-leakage bidirectional voltage limiter; prevents ADC saturation during ESD events or wiring faults. Use Value: 0.10 µA IR ensures <1 µV offset error in 10 MΩ sensor bridges; 2.0 pF CT avoids bandwidth degradation above 100 kHz. |
| USB-C Port Protection | Low-Power IoT Node Power Management |
|
Use Scenario: Polarity protection for VBUS and CC line conditioning in compact USB-C receptacles. IC Role / Device Role / Timing Role: Dual-anode Schottky array providing independent forward conduction paths for power and control lines. Use Value: Symmetrical SOT363 layout simplifies layout routing; 0.41 V VF avoids violating USB-C 5 V tolerance under 100 mA load. |
Use Scenario: Re-circulating diode in buck converter feedback loop and backup battery switchover circuitry. IC Role / Device Role / Timing Role: Low-loss freewheeling path and automatic power-source selection switch. Use Value: 70 mA IFM rating supports intermittent 50 mA peak loads; 625 °C/W RθJA allows operation at 85°C ambient without derating. |
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, SOD-523 package | Higher current but lower voltage rating; lacks dual-channel integration and AEC-Q101 qualification | Select only when higher forward current (>10×) is required and dual-channel consolidation is unnecessary |
| BAT54CW-7-F | Dual-channel, 30 V VR, 200 mA IF, 0.33 V VF @ 10 mA, SOT323 package | Higher IF and lower VF at higher currents, but 30 V VR insufficient for 12 V automotive systems; not AEC-Q101 qualified | Acceptable for non-automotive 3.3/5 V logic protection where 70 V blocking is not required |
Compared with RB050M-30TR and BAT54CW-7-F, BAS70TWQ-7-F uniquely combines 70 V blocking, AEC-Q101 qualification, dual-channel symmetry, and sub-0.5 V forward drop in a space-constrained SOT363 - making it the only viable option for automotive-grade dual-rail protection below 1 mm².

FAQ
Is BAS70TWQ-7-F pin-compatible with BAS70DW-05Q-7-F?
Yes - both share identical SOT363 pinout and symmetrical dual-anode/dual-cathode configuration. BAS70TWQ-7-F uses the same K73 marking code and thermal/mechanical specs as BAS70DW-05Q-7-F, differing only in internal diode pairing (TW = twin anode/twin cathode; DW-05 = common cathode). Layout compatibility is maintained.
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is +125°C. With a thermal resistance of 625°C/W and 200 mW maximum power dissipation, sustained operation at full rating requires ambient ≤ 100°C when mounted on FR-4 with recommended pad layout. Derating begins linearly above +25°C ambient per Figure 4.
Does BAS70TWQ-7-F support reflow soldering per JEDEC J-STD-020?
Yes - it is rated for moisture sensitivity level 1 (MSL-1), meaning unlimited floor life and compatibility with standard lead-free reflow profiles (peak 260°C, 20–40 sec). Matte tin plating ensures solderability per MIL-STD-202, Method 208, and the UL 94V-0 mold compound withstands thermal cycling without delamination.
How does the PN junction guard ring improve system-level ESD robustness?
The integrated guard ring provides edge termination that suppresses avalanche breakdown at diode peripheries, increasing ESD withstand voltage by ≥3× versus standard Schottky structures. This enables direct IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) protection without external TVS devices in signal-line applications.
