Product details
Overview
BAV70S E6433 from Nexperia is a silicon double diode in common-cathode configuration housed in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-optimized for high-speed switching in automotive signal routing and USB port protection circuits.
For engineers reviewing the BAV70S E6433 datasheet, BAV70S E6433 pinout, BAV70S E6433 application, or BAV70S E6433 equivalent, key selection criteria include its AEC-Q101 qualification, 1.5 pF junction capacitance at 0 V, thermal resistance of ≤260 K/W (junction-to-soldering-point), and guaranteed 85 V breakdown voltage at 100 µA test current.
Technical Context
This dual diode operates with two anodes sharing one cathode terminal, enabling bidirectional clamping or steering functions in compact signal paths. Its 4 ns reverse recovery time and low 1.5 pF capacitance support >100 MHz signal integrity in USB 2.0 and CAN FD data lines.
The device is characterized across temperature (–65 °C to +150 °C) with IR ≤ 0.15 µA at VR = 70 V and TA = 25 °C, and VF ≤ 1250 mV at IF = 150 mA-enabling stable performance in thermally constrained automotive ECUs and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression with 3× safety margin |
| Forward Current (IF) | 200 mA - sufficient for logic-level signal clamping without derating at TS ≤ 85 °C |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 100+ MHz digital interfaces like USB PHY and LVDS receivers |
| Junction Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - minimizes signal loading on high-speed data lines |
| Thermal Resistance (RthJS) | ≤260 K/W - allows 250 mW power dissipation with <10 °C junction rise above solder point at steady state |
| Breakdown Voltage (V(BR)) | 85 V @ I(BR) = 100 µA - ensures reliable overvoltage blocking under worst-case leakage conditions |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
BAV70S E6433 is packaged in SC74 (SOT-363), a 6-pin surface-mount plastic package with symmetric pin layout and no defined Pin 1 orientation in reel. The device uses common-cathode topology: Pins 1 & 2 are Anode 1 and Anode 2; Pin 3 is Cathode (shared); Pins 4–6 are unused (NC) or internal tie points per manufacturer marking layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input node for first diode path; connects to signal line requiring clamping or steering |
| Pin 2 | Anode 2 | Input node for second diode path; enables dual-channel protection or logic OR function |
| Pin 3 | Cathode (common) | Shared output node tied to reference rail (e.g., VCC or ground); defines conduction direction |
| Pins 4–6 | No Connect / Internal Tie | Not electrically functional; mechanical support or thermal slug-no PCB routing required |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual diode | Enables compact bidirectional ESD clamping or signal steering without discrete pairing |
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment applications per stress test requirements |
| 4 ns reverse recovery | Supports clean edge transitions in 100 Mbps+ serial links without ringing or overshoot |
| 1.5 pF junction capacitance | Preserves signal rise/fall times in USB 2.0 (480 Mbps) and CAN FD (5 Mbps) interfaces |
| RoHS-compliant, Pb-free | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
Applications
| USB 2.0 Data Line Protection | Automotive LIN Bus Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines against ±15 kV ESD events per IEC 61000-4-2. IC Role / Device Role / Timing Role: Dual-anode clamping diode shunting transients to VBUS or GND while preserving 480 Mbps data eye. Use Value: 1.5 pF CT and 4 ns trr prevent signal distortion; common-cathode layout reduces PCB footprint by 30% vs. discrete pair. | Use Scenario: Isolating microcontroller UART pins from LIN bus transceivers subject to load-dump pulses. IC Role / Device Role / Timing Role: High-speed steering diode routing wake-up signals and data frames between MCU and LIN PHY.

Use Value: 4 ns trr ensures <10 ns latency in carrier-sense timing; SC74 package fits 1.2 mm pitch routing constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,115 (Nexperia) | SOT-23 package, single common-cathode pair, identical electrical specs but higher RthJS (460 K/W) | Limited to lower-power signal paths due to thermal constraint; not suitable for sustained 150 mA operation | Select when board space is constrained to 3-pin footprint and thermal load is <100 mW |
| ESD9X5.0ST5G (ON Semiconductor) | Single-channel ESD protector with 5.0 V working voltage, 12 pF CT, and 0.5 ns trr | Optimized for I/O ESD only-not for DC clamping or bidirectional steering; lacks dual-anode architecture | Select only for dedicated IEC 61000-4-2 compliance where low capacitance is secondary to clamping voltage |
Compared with BAV99,115 and ESD9X5.0ST5G, BAV70S E6433 uniquely balances dual-channel functionality, 4 ns speed, 1.5 pF capacitance, and AEC-Q101 qualification-making it the only choice for automotive USB/LIN dual-rail protection requiring both speed and reliability.

FAQ
What is the maximum continuous forward current for BAV70S E6433 at 85 °C case temperature?
The datasheet specifies that BAV70S E6433 supports 200 mA forward current when the soldering-point temperature (TS) does not exceed 85 °C. This rating is validated under steady-state conditions with proper PCB copper pour and thermal relief design per Nexperia Application Note AN10275.
Is BAV70S E6433 pin-compatible with BAV70W or BAV70U?
No-BAV70S (SC74/SOT-363) has a 6-pin layout with common-cathode dual diode configuration, while BAV70W (SOT-323) and BAV70U (SOT-323 variant) use 3-pin packages with identical pinout but different thermal ratings and power dissipation limits. Mechanical and electrical pin mapping is not interchangeable.
Does BAV70S E6433 meet IEC 61000-4-2 Level 4 ESD immunity?
BAV70S E6433 itself is not certified to IEC 61000-4-2; however, its 85 V breakdown voltage, sub-µA leakage, and 4 ns recovery enable circuit-level designs that achieve ±15 kV contact discharge protection when combined with appropriate series impedance and PCB layout per IEC 61000-4-2 test setup.
Can BAV70S E6433 be used in place of a single BAV70 diode in a design?
Yes-if only one diode path is needed, Pin 2 can be left unconnected while using Pin 1 and Pin 3 as a functional anode–cathode pair. However, the unused anode (Pin 2) must be terminated to avoid floating node effects; grounding it via 100 kΩ resistor is recommended for noise immunity in sensitive analog paths.
