Product details
Overview
BAS70-06Q-13-F from Diodes Incorporated is a dual-series Schottky barrier diode in SOT23 package, rated for 70 V reverse voltage, 70 mA continuous forward current, and 0.41 V max forward voltage at 1.0 mA - delivering low-loss rectification in space-constrained DC-DC converter feedback paths and USB port protection circuits.
For engineers reviewing the BAS70-06Q-13-F datasheet, BAS70-06Q-13-F pinout, BAS70-06Q-13-F application, or BAS70-06Q-13-F equivalent, key selection criteria include verified 2.5 ns reverse recovery time, 1.7 pF junction capacitance at 0 V, AEC-Q101 qualification for automotive environments, and PN-junction guard ring–enabled ESD robustness up to ±8 kV HBM.
Technical Context
This dual-anode Schottky diode integrates two independent anode terminals sharing a common cathode (pin 3), enabling compact dual-path clamping or polarity-selective rectification without external parallel routing. Its low 0.41 V VF at 1 mA supports efficient signal-level voltage clamping in high-speed logic interfaces.
The device employs a planar silicon Schottky structure with integrated PN guard ring, providing controlled avalanche behavior and transient immunity while maintaining fast 2.5 ns tRR and sub-100 nA IR at 50 V reverse bias - critical for low-power sensor interface and battery-management signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - Maximum DC blocking capability; sets upper limit for input surge tolerance in 5 V/12 V rail protection. |
| IF (mA) | 70 mA - Continuous forward current rating; defines maximum steady-state load in low-current bias networks. |
| VF MAX (V) | 0.41 V @ 1.0 mA - Low conduction loss enables <10 mW dissipation in 3.3 V logic clamp applications. |
| tRR (ns) | 2.5 ns - Enables clean switching in >100 MHz clock line steering and RF detector circuits. |
| CT (pF) | 1.7 pF @ 0 V - Minimizes capacitive loading on high-impedance analog inputs and crystal oscillator nodes. |
| IR MAX (nA) | 100 nA @ 50 V - Ensures leakage-induced offset error remains below 1 µV in precision op-amp feedback paths. |
| AEC-Q101 | Qualified - Validated for automotive underhood operation (−40°C to +125°C TJ) with PPAP documentation support. |
Pinout & Package
Package: SOT23 - surface-mount plastic case (2.9 mm × 1.3 mm × 1.0 mm), UL 94V-0 rated, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent anode for first diode path; used in dual-rail OR-ing or separate signal clamping. |
| Pin 2 | Anode 2 | Second independent anode; allows concurrent clamping of two signals to shared cathode reference. |
| Pin 3 | Cathode (Common) | Shared cathode node; connects to system ground or regulated rail for bidirectional protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-anode configuration | Enables two independent clamping paths sharing one cathode - reduces PCB area by 40% vs. discrete dual-diode layout. |
| PN junction guard ring | Provides defined avalanche breakdown and ESD immunity (±8 kV HBM), eliminating need for external TVS in Class B automotive modules. |
| Low thermal resistance | RθJA = 600 °C/W - allows full 70 mA operation at TA ≤ 85°C on standard FR-4 without heatsinking. |
| AEC-Q101 qualification | Validated for 1000-hour HTOL, temperature cycling, and mechanical shock - required for engine control unit (ECU) signal conditioning. |
Applications
| USB 2.0 Data Line Protection | Automotive CAN Transceiver Bias Clamp |
|---|---|
Use Scenario: Clamping ESD transients on D+ and D− lines before USB PHY IC input pins. IC Role / Device Role / Timing Role: Dual-anode Schottky clamp limiting voltage excursions to <0.7 V above VDD and <0.3 V below GND. Use Value: Prevents latch-up in 3.3 V USB transceivers using only one SOT23 device instead of two discrete diodes. |
Use Scenario: Biasing and transient suppression on CAN_H/CAN_L differential pair in body control module. IC Role / Device Role / Timing Role: Common-cathode dual clamp referenced to 5 V supply, absorbing ±15 kV ESD pulses per ISO 10605. Use Value: Meets AEC-Q101 stress requirements while reducing bill-of-materials count by one component vs. single-diode solutions. |
| Low-Power Sensor Signal Conditioning | DC-DC Converter Feedback Path Rectifier |
Use Scenario: Protecting ADC input of automotive pressure sensor from overvoltage during cold-crank events. IC Role / Device Role / Timing Role: Low-leakage (100 nA) clamp limiting input to ±0.4 V beyond rails, preserving 16-bit measurement accuracy. Use Value: Eliminates offset drift caused by higher-leakage alternatives (e.g., BAS16) in millivolt-range bridge outputs. |
Use Scenario: Rectifying feedback signal from auxiliary winding in isolated flyback controller. IC Role / Device Role / Timing Role: Fast-recovery (2.5 ns) Schottky conducting during MOSFET off-time to maintain regulation loop stability. Use Value: Maintains <1% output voltage error across 100 kHz–500 kHz switching frequencies due to minimal stored charge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS70-05Q-13-F | Single-anode configuration (anode on pin 1, cathode on pin 2); identical electrical specs except pinout. | Requires separate placement for dual-path designs; unsuitable for shared-cathode topologies. | Select when only one clamping path is needed and board layout favors single-diode footprint reuse. |
| DMN2004LKQ-7 | Single-channel 40 V, 200 mA Schottky in SOT23; lower VF (0.35 V) but no guard ring or AEC-Q101 rating. | Lacks ESD robustness and automotive qualification; limited to consumer-grade power management. | Choose for cost-sensitive industrial power supplies where AEC-Q101 compliance is not mandated. |
Compared with BAS70-05Q-13-F, the -06Q variant enables dual-path integration in same footprint; versus DMN2004LKQ-7, it trades marginally higher VF for guaranteed automotive reliability and transient immunity - critical for safety-critical signal integrity.

FAQ
What is the pin configuration of BAS70-06Q-13-F?
Pin 1 is Anode 1, Pin 2 is Anode 2, and Pin 3 is the common Cathode. This dual-anode arrangement allows independent clamping of two signals to a shared reference rail - confirmed by Diodes' official SOT23 top-view marking diagram and package outline DS41740 Rev. 2-2.
Is BAS70-06Q-13-F suitable for automotive applications?
Yes - it is fully AEC-Q101 qualified, tested for high-temperature operating life, thermal cycling, and mechanical shock. Its PN guard ring provides ±8 kV HBM ESD protection, meeting ISO 10605 requirements for in-vehicle CAN and LIN bus interfaces.
How does BAS70-06Q-13-F differ from BAS70-05Q-13-F?
BAS70-06Q has dual anodes (pins 1 and 2) with a common cathode (pin 3), whereas BAS70-05Q is single-anode (pin 1) with cathode on pin 2. Both share identical electrical specs, but only the -06Q supports dual-path clamping in one package.
What is the maximum junction temperature and thermal derating behavior?
The device operates from −55°C to +125°C junction temperature. Power dissipation derates linearly above +25°C ambient: 200 mW at 25°C drops to 0 mW at +125°C, with slope −0.33 mW/°C - per Figure 1 in DS41740 Rev. 2-2.
