Product details
Overview
BAS70-06-HE3_A-18 from Vishay Semiconductors is a dual common-anode Schottky diode in SOT-23 package, rated for 70 V repetitive peak reverse voltage, 200 mA forward continuous current, and 5 ns reverse recovery time. It features low 410 mV forward voltage at 1 mA, 1.5–2 pF junction capacitance at 0 V, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the BAS70-06-HE3_A-18 datasheet, BAS70-06-HE3_A-18 pinout, BAS70-06-HE3_A-18 application, or BAS70-06-HE3_A-18 equivalent, key selection criteria include common-anode configuration, fast switching in signal routing or clamping, low VF for power-sensitive bias networks, and MSL 1 handling for high-reliability assembly.
Technical Context
The BAS70-06-HE3_A-18 integrates two Schottky diodes sharing a single anode terminal (Pin 1), with cathodes on Pins 2 and 3-enabling dual-channel clamping or steering from one supply rail. Its 70 V VRRM and 125 °C max junction temperature support operation in automotive body control modules and industrial sensor interfaces.
With 5 ns trr, 20–100 nA IR at 50 V, and 1.5–2 pF CD at 1 MHz, the device delivers low-loss, high-speed performance in RF detector front-ends, logic-level translation, and precision analog signal conditioning where minimal charge injection and leakage are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - supports reverse blocking in 48 V automotive systems and 24 V industrial I/O protection |
| IF (cont) | 200 mA - sufficient for biasing small-signal transistors or driving LED indicators without thermal derating |
| VF @ 1 mA | 410 mV - enables ultra-low-threshold clamping in battery-monitoring ADC reference paths |
| trr | 5 ns - ensures clean edge integrity in 10–50 MHz clock signal steering or RF envelope detection |
| CD @ 0 V | 1.5–2 pF - minimizes capacitive loading on high-impedance sensor nodes and RF mixer inputs |
| IR @ 50 V | 20–100 nA - maintains accuracy in precision voltage reference dividers and leakage-critical sample-hold circuits |
| Tj max | 125 °C - qualified for under-hood automotive ECUs and sealed industrial enclosures without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54AWT1G | Same SOT-23 package, common-anode, but lower 30 V VRRM and higher 600 mV VF at 10 mA | Restricted to ≤24 V systems; unsuitable for 48 V automotive or industrial 36 V rails | Select only when VRRM ≤30 V suffices and cost is prioritized over leakage or speed |
| NSR0230HT1G | Single Schottky in SOD-123, 30 V VRRM, 330 mV VF at 10 mA, no AEC-Q101 qualification | Requires two devices for dual-channel function; lacks automotive reliability validation and MSL 1 rating | Use only in non-automotive consumer designs where footprint and qualification are secondary |
Compared with SBAT54AWT1G and NSR0230HT1G, the BAS70-06-HE3_A-18 uniquely combines 70 V blocking, AEC-Q101 qualification, and true dual common-anode integration in SOT-23-enabling single-component protection in space-constrained automotive and industrial control nodes where reliability and voltage margin are non-negotiable.

FAQ
What is the pin configuration of the BAS70-06-HE3_A-18?
The BAS70-06-HE3_A-18 uses a common-anode configuration in SOT-23: Pin 1 is the shared anode, Pin 2 is Cathode 1, and Pin 3 is Cathode 2. This layout enables dual-channel clamping from a single supply rail without additional routing layers, and is confirmed by Vishay's mechanical drawing and marking code "76G" in the datasheet.
Is the BAS70-06-HE3_A-18 qualified for automotive applications?
Yes, the BAS70-06-HE3_A-18 is explicitly AEC-Q101 qualified, as indicated by the "-HE3" suffix and verified in the Vishay ordering table and absolute maximum ratings section. It meets stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22-A114, making it suitable for under-hood and cabin ECUs.
What is the maximum operating temperature for the BAS70-06-HE3_A-18?
The BAS70-06-HE3_A-18 has a maximum junction temperature of 125 °C and an operating ambient temperature range of -55 °C to +125 °C. This rating is validated under infinite heatsink conditions and applies directly to the BAS70-06-HE3_A-18 variant per the thermal characteristics table in Document Number 86402.
How does the BAS70-06-HE3_A-18 compare to the BAS70-04-HE3_A-18 in circuit function?
The BAS70-06-HE3_A-18 is common-anode, while the BAS70-04-HE3_A-18 is dual serial-meaning its anode connects to cathode internally. This makes BAS70-06-HE3_A-18 ideal for parallel clamping to one rail, whereas BAS70-04-HE3_A-18 suits cascaded voltage dropping or series signal conditioning. Pinouts and internal topology differ; they are not interchangeable.
What packaging option does BAS70-06-HE3_A-18 use, and what is its moisture sensitivity level?
The BAS70-06-HE3_A-18 ships in 8 mm tape on 13″ reels (10,000 units/reel) with packaging code "18", and carries MSL 1 per J-STD-020-meaning unlimited floor life and no baking required prior to reflow. This is specified in the Parts Table and Mechanical Data sections of the Vishay datasheet.
