Product details
Overview
BAV99 E6433 from Nexperia is a dual-series silicon switching diode in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-designed for high-speed signal routing and polarity protection in automotive CAN bus interface circuits.
For engineers reviewing the BAV99 E6433 datasheet, BAV99 E6433 pinout, BAV99 E6433 application, or BAV99 E6433 equivalent, key selection criteria include its dual-series configuration, low 1.25 V VF at 150 mA, AEC-Q101 qualification, and thermal resistance of ≤260 K/W (junction-to-soldering point).
Technical Context
This dual-diode array integrates two independent silicon PN junctions in series orientation within a single SC74 package, enabling bidirectional clamping and fast transition between conduction states. Its 1.5 pF capacitance at 0 V and 4 ns trr support >100 MHz signal integrity in ESD-protected data lines.
The device operates across −65 °C to +150 °C with guaranteed IR ≤0.15 µA at 70 V and 25 °C, and maintains VF ≤1.25 V up to 150 mA-critical for low-loss bias networks in automotive sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation in 100+ MHz digital signal paths |
| Forward Voltage (VF) | 1.25 V @ 150 mA - minimizes power loss in series-biased protection circuits |
| Diode Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - preserves signal edge fidelity in high-speed USB/CAN stubs |
| Junction Temperature (Tj) | 150 °C - meets under-hood thermal requirements per AEC-Q101 stress testing |
| Thermal Resistance (RthJS) | ≤260 K/W - allows sustained 200 mA DC operation with TS ≤85 °C on standard PCB copper |
Pinout & Package
SC74 (SOT-363) surface-mount package with 6-pin symmetrical layout; no defined Pin 1 orientation in tape-and-reel-requires visual alignment using top-side marking (A7s) and pin 1 indicator notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode in series chain; connects to signal source in clamp topology |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Shared internal node-enables series connection without external trace routing |
| 3 | Cathode of Diode 2 | Output node tied to protected IC input or ground reference in bidirectional ESD path |
| 4 | Anode of Diode 1 | Duplicate anode terminal for improved current sharing and thermal distribution |
| 5 | Cathode of Diode 1 / Anode of Diode 2 | Duplicate shared node-supports parallel mounting or redundancy in safety-critical paths |
| 6 | Cathode of Diode 2 | Duplicate cathode terminal-reduces bond wire inductance in high-frequency transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Dual-series configuration | Enables symmetric bidirectional clamping without external series resistor or layout asymmetry |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU and JESD204B lead finish standards for industrial reflow |
| Low leakage current | IR ≤0.15 µA @ 70 V, 25 °C ensures minimal standby power draw in always-on sensor nodes |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | Same die, SOT-323 package; RthJS ≤160 K/W but lower Ptot (250 mW vs 330 mW for BAV99) | Better thermal performance in space-constrained layouts; reduced surge capability due to lower IF rating | Select when board area is limited and peak pulse duration <100 µs |
| MMBD7000LT1G | Single-diode SOT-23; requires external series connection; VF = 1.25 V @ 150 mA, trr = 4 ns, but no AEC-Q101 qualification | Lacks automotive qualification and integrated dual-series topology-increases layout complexity and failure risk | Acceptable only for non-automotive consumer designs where cost outweighs reliability |
Compared with BAV99 E6433, BAV99W offers superior thermal resistance in smaller footprint but sacrifices 25% DC current handling; MMBD7000LT1G lacks qualification and integration, increasing design validation burden for automotive use cases.

FAQ
Is BAV99 E6433 pin-compatible with BAV99S or BAV99U?
No. BAV99 E6433 uses SC74 (SOT-363) packaging with 6 pins in dual-series configuration, while BAV99S uses SOT-363 but different internal connectivity, and BAV99U uses SC74 with distinct pin mapping. Mechanical fit does not guarantee functional equivalence-refer to respective package drawings and internal schematics.
What is the maximum allowable continuous forward current at 100°C ambient?
At TA = 100 °C, the derated forward current is 125 mA for BAV99 E6433, calculated from its 200 mA rating at 25 °C and thermal resistance curve showing 62.5% current retention at that temperature per the manufacturer's IF vs. TS graph for SC74 packages.
Does BAV99 E6433 support bidirectional ESD protection per IEC 61000-4-2?
Yes. Its dual-series configuration provides symmetrical clamping in both directions, and its 4 ns trr and 1.5 pF CT meet timing and capacitive loading requirements for Level 4 (±15 kV contact) ESD protection on data lines when used with appropriate series impedance.
Can BAV99 E6433 replace BAT54S in a 3.3 V logic-level circuit?
No. BAT54S is a dual-common-cathode Schottky diode with VF ≈ 0.3 V, while BAV99 E6433 is a dual-series silicon PN diode with VF ≥ 0.715 V at 1 mA. Substituting it would increase forward drop by >400 mV, risking logic threshold violations and excessive power dissipation.
