Product details

Overview

BAS70-06Q-7-F from Diodes Incorporated is a 70 mA surface-mount Schottky barrier diode in SOT23 package, featuring 70 V peak reverse voltage, 0.41 V max forward voltage at 1.0 mA, and 100 nA max reverse leakage at 50 V. It integrates a PN junction guard ring for transient and ESD protection and is AEC-Q101 qualified for automotive applications such as power rail clamping in engine control units.

For engineers reviewing the BAS70-06Q-7-F datasheet, BAS70-06Q-7-F pinout, BAS70-06Q-7-F application, or BAS70-06Q-7-F equivalent, key selection criteria include low VF for efficiency-critical 3.3 V/5 V rail protection, fast 2.5 ns reverse recovery for high-frequency switching nodes, and SOT23 footprint compatibility with space-constrained PCB layouts.

Technical Context

This dual-anode Schottky diode (BAS70-06Q) shares cathode configuration-pins 1 and 2 are anodes, pin 3 is common cathode-enabling dual independent clamping paths from two inputs to a shared return rail. Its 1.7 pF junction capacitance at 0 V supports RF bypass and EMI filtering up to ~100 MHz.

The device operates across –55 °C to +125 °C junction temperature, with thermal resistance of 600 °C/W (junction-to-ambient on FR-4), and derates linearly to zero power at 150 °C ambient per Figure 1. Guard ring structure ensures robustness against ISO 7637-2 pulse transients in automotive 12 V systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Peak Reverse Voltage	70 V - supports clamping in 48 V automotive subsystems and 24 V industrial controls without breakdown
Forward Voltage	0.41 V max @ 1.0 mA - minimizes conduction loss in low-current bias and sensing circuits
Reverse Leakage	100 nA max @ 50 V - ensures negligible standby current in battery-backed monitoring nodes
Reverse Recovery Time	2.5 ns typ - enables use in >100 MHz signal routing and high-speed logic level translation
Junction Capacitance	1.7 pF @ 0 V - suitable for RF decoupling and ESD protection on high-speed data lines (e.g., CAN, LIN)
Thermal Resistance	600 °C/W - requires minimal copper area for thermal relief in compact SOT23 layouts
AEC-Q101 Qualified	Yes - validated for automotive underhood and cabin applications per stress test requirements

Pinout & Package

SOT23-3 package: molded plastic case, UL 94V-0 rated, 0.008 g weight, moisture sensitivity level 1. Pin 1 = Anode 1, Pin 2 = Anode 2, Pin 3 = Common Cathode.

Pin/Terminal	Circuit Role	Design Meaning

Use Scenario: Protecting analog front-end inputs of 24-bit delta-sigma ADCs from ESD events.

IC Role / Device Role / Timing Role: Low-capacitance (1.7 pF) bidirectional clamp shunting ESD energy before it reaches sensitive input stages.

Use Value: Maintains signal integrity below 100 kHz while passing IEC 61000-4-2 Level 4 testing.

USB Data Line Protection

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-anode Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SBAT54AWT1G	Same SOT23-3, 30 V V_R, 0.32 V V_F @ 10 mA, 2.0 pF C_T	Limited to ≤30 V systems; lower VF benefits higher-current bias networks	Select when operating voltage ≤30 V and sub-10 mA forward current dominates design
BAT54CW	Same pinout, 30 V V_R, 0.24 V V_F @ 10 mA, no AEC-Q101 qualification	Not qualified for automotive; higher leakage (1 µA) limits battery-life-critical use	Prefer for cost-sensitive consumer electronics where AEC-Q101 and low IR are nonessential

Compared with SBAT54AWT1G and BAT54CW, BAS70-06Q-7-F uniquely delivers 70 V blocking capability with AEC-Q101 validation-critical for 48 V mild-hybrid architectures-while maintaining sub-0.45 V forward drop and <100 nA leakage for precision low-power systems.

FAQ

What is the pin configuration of BAS70-06Q-7-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' DS41740 Rev. 2 schematic diagram and top-marking layout.

Is BAS70-06Q-7-F suitable for 48 V automotive systems?

Yes. With a 70 V peak reverse voltage rating and AEC-Q101 qualification, it supports clamping in 48 V mild-hybrid architectures and withstands load-dump transients per ISO 7637-2. Its guard ring structure ensures reliability under repeated surge stress.

How does BAS70-06Q-7-F differ from BAS70-05Q-7-F?

BAS70-06Q-7-F has dual anodes and one common cathode (pinout: A1–A2–K), whereas BAS70-05Q-7-F is a single Schottky diode in SOT23-3 (anode–cathode–NC). The marking codes '76'/'7F' identify BAS70-06Q per Diodes' date code document DS41740.

Can BAS70-06Q-7-F replace BAT54 series diodes?

Only in voltage-limited cases: BAS70-06Q-7-F offers 70 V blocking versus BAT54's 30 V, but shares identical SOT23-3 footprint and dual-anode topology. Substitution requires verifying system voltage margins and confirming AEC-Q101 compliance is not required in the target application.
