Product details
Overview
BAS70-04Q-13-F from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode in SOT23 package, rated for 70 V peak reverse voltage, 70 mA forward current, and 0.41 V max forward voltage at 1.0 mA. It features a PN junction guard ring for transient and ESD protection and is AEC-Q101 qualified for automotive applications.
For engineers reviewing the BAS70-04Q-13-F datasheet, BAS70-04Q-13-F pinout, BAS70-04Q-13-F application, or BAS70-04Q-13-F equivalent, key selection criteria include low VF (≤410 mV @ 1 mA), ultrafast tRR (2.0 ns), 70 V VR, AEC-Q101 qualification, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual Schottky diode integrates two independent anode-cathode junctions in a single SOT23-3 package with common cathode configuration (Pin 1 = Anode A, Pin 2 = Cathode, Pin 3 = Anode B). Its guard-ringed structure suppresses leakage under ESD stress while maintaining sub-5 ns reverse recovery.
Designed for high-frequency signal clamping and polarity protection in automotive infotainment and body control modules, it operates across –55°C to +125°C with <100 nA IR at 50 V reverse bias and 2.0 pF junction capacitance at 0 V - enabling clean signal integrity in 1–10 MHz analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 70 V - Withstands up to 70 V repetitive reverse voltage without breakdown, suitable for 48 V automotive supply rail protection. |
| VF MAX | 410 mV @ 1 mA - Enables low-loss signal clamping and voltage translation in low-power sensor interfaces. |
| tRR | 2.0 ns - Supports >100 MHz switching in RF detector and high-speed logic clamp circuits. |
| IR MAX | 100 nA @ 50 V - Ensures minimal leakage in battery-backed real-time clock backup paths. |
| CT | 2.0 pF @ 0 V - Minimizes capacitive loading on high-impedance analog inputs such as ADC reference dividers. |
| TJ Range | –55°C to +125°C - Validated for under-hood engine control unit (ECU) and transmission control module environments. |
Pinout & Package
Package: SOT23-3, surface-mount plastic package with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode A | First Schottky junction anode - connects to input signal or power rail requiring clamping or polarity protection. |
| Pin 2 | Cathode (Common) | Shared cathode node - ties both diodes to reference potential (e.g., VCC or ground) for dual-path protection. |
| Pin 3 | Anode B | Second Schottky junction anode - enables independent clamping of a second signal line without additional package area. |
Key Features
| Feature | Design Value |
|---|---|
| PN Junction Guard Ring | Provides robust ESD immunity (IEC 61000-4-2 Level 4) and transient suppression without sacrificing VF or speed. |
| AEC-Q101 Qualification | Validated for automotive use with PPAP documentation support and IATF 16949 manufacturing traceability. |
| Low Capacitance (2.0 pF) | Preserves bandwidth in RF front-end limiter and high-speed data line protection (e.g., CAN FD stubs). |
| Green Construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb), compliant with RoHS 3 and automotive ELV directives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAS70-04Q-7-F | Same die, identical electrical specs, but packaged in 3,000-piece tape-and-reel (vs. 10,000 for -13-F). | No functional difference; suited for lower-volume prototyping or pilot builds. | Select when smaller reel size aligns with SMT line changeover frequency or inventory turnover targets. |
| NSR20F70NXT5G | Single-channel SOD-523; VF = 450 mV @ 1 mA; tRR = 3.5 ns; no AEC-Q101 rating. | Lacks dual-anode topology and automotive qualification; requires two devices for same function. | Use only in non-automotive consumer designs where cost-per-diode is prioritized over board space and qualification. |
Compared with SBAS70-04Q-7-F, the BAS70-04Q-13-F offers higher reel quantity for production efficiency; versus NSR20F70NXT5G, it delivers dual-channel integration, AEC-Q101 compliance, and faster tRR - critical for automotive signal integrity and footprint reduction.

FAQ
What is the pin configuration of BAS70-04Q-13-F?
It uses a standard SOT23-3 package with Pin 1 = Anode A, Pin 2 = Common Cathode, Pin 3 = Anode B. This dual-anode/common-cathode arrangement supports independent clamping of two signals sharing one return path, confirmed by Diodes' DS11007 Rev. 27 pin diagram and marking code K7D.
Is BAS70-04Q-13-F suitable for 48 V automotive systems?
Yes - its 70 V VRRM rating provides 46% headroom above nominal 48 V rail, and its AEC-Q101 qualification covers extended temperature operation (–55°C to +125°C), thermal cycling, and ESD robustness required for 48 V mild-hybrid architectures.
How does the PN junction guard ring improve reliability?
The integrated guard ring reduces electric field crowding at the junction edge, suppressing premature avalanche and leakage under ESD stress. Per DS11007, this enables ≥15 kV IEC 61000-4-2 contact discharge immunity without degrading forward voltage or switching speed.
Can BAS70-04Q-13-F replace BAS70-04-7-F in existing designs?
Yes - both share identical die, electrical specs, and SOT23-3 package. The only difference is packaging: -13-F uses 10,000-piece tape-and-reel versus -7-F's 3,000-piece reel. No layout or schematic changes are needed for drop-in replacement in production.
