Product details
Overview
BAV99W H6433 from Nexperia is a dual-series silicon switching diode in SOT323 (SC74) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-designed for high-speed signal routing and ESD protection in USB data lines and I²C bus interfaces.
For engineers reviewing the BAV99W H6433 datasheet, BAV99W H6433 pinout, BAV99W H6433 application, or BAV99W H6433 equivalent, key selection criteria include its 1.5 pF junction capacitance at 0 V, low 1250 mV VF at 150 mA, AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of ≤160 K/W to soldering point.
Technical Context
The BAV99W integrates two independent diodes in series configuration within a single SOT323 package, enabling bidirectional clamping and polarity-insensitive transient suppression. Its 4 ns trr and 1.5 pF CT support >100 MHz signal integrity in high-speed digital interfaces.
Thermal design is constrained by a maximum junction temperature of 150 °C and a junction-to-soldering-point thermal resistance of ≤160 K/W, requiring PCB copper area optimization for sustained 200 mA operation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V industrial bus and 3.3/5 V logic rail protection without breakdown |
| Forward Current (IF) | 200 mA - enables continuous signal-level current handling in level-shifting and bus termination |
| Reverse Recovery Time (trr) | 4 ns - ensures minimal switching distortion in 10–50 MHz clock/data paths |
| Junction Capacitance (CT) | 1.5 pF @ 0 V - preserves signal rise/fall times in USB 2.0 and I²C applications |
| Forward Voltage (VF) | 1250 mV @ 150 mA - limits power loss to <188 mW during peak conduction |
| Thermal Resistance (RthJS) | ≤160 K/W - requires ≥25 mm² 1-oz copper pad for safe 200 mA DC operation at TA = 85 °C |
Pinout & Package
SOT323 (SC74) surface-mount package with 3 terminals: Pin 1 (Anode 1), Pin 2 (Cathode 1 / Anode 2), Pin 3 (Cathode 2). Symmetric marking; no defined Pin 1 orientation in reel per manufacturer specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first diode in series path; connects to protected signal line |
| Pin 2 | Cathode of Diode 1 / Anode of Diode 2 | Internal common node; enables series clamping topology across both diodes |
| Pin 3 | Cathode of Diode 2 | Output node tied to reference (e.g., VCC or GND) for bidirectional ESD clamp |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment applications per stress test requirements |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
| Dual-series configuration | Enables symmetric bidirectional clamping without external biasing components |
| Low leakage at high temp | IR ≤ 50 µA @ VR = 70 V, TA = 150 °C - maintains signal integrity in hot environments |
Applications
| USB 2.0 Data Line Protection | I²C Bus Level Shifting |
|---|---|
Use Scenario: Protecting D+ and D− lines from ESD events up to ±15 kV contact discharge per IEC 61000-4-2. IC Role / Device Role: Bidirectional series clamp limiting voltage excursion to <3.6 V during transients. Use Value: 1.5 pF CT avoids signal degradation; 4 ns trr prevents data corruption at 480 Mbps. | Use Scenario: Translating 3.3 V microcontroller I/O to 5 V sensor interface while suppressing cross-talk. IC Role / Device Role: Passive level shifter using forward-biased diode drop and series impedance. Use Value: 1250 mV VF at 150 mA ensures stable 1.8 V offset; 200 mA IF rating supports multi-sensor bus loading. |
| Automotive CAN FD Signal Conditioning | Industrial RS-485 Receiver Input Protection |
Use Scenario: Front-end transient suppression on CAN FD nodes operating at 2–5 Mbps in 12 V vehicle systems. IC Role / Device Role: High-speed clamping diode pair limiting differential noise spikes before receiver input. Use Value: AEC-Q101 qualification ensures reliability; 80 V VR withstands load-dump induced surges. | Use Scenario: Guarding RS-485 receiver inputs against induced surges in factory-floor wiring runs.

Use Value: ≤160 K/W RthJS allows thermal stability under repeated 1 kV surge pulses per IEC 61000-4-5. |
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 (Nexperia) | Same die, identical electrical specs; differs only in reel packaging (3,000 pcs vs. H6433's unspecified quantity) | No functional difference; suitable for same PCB layouts and thermal designs | Select when standard reel size or traceability requirements align with distributor inventory |
| MMBD7000LT1G (ON Semiconductor) | Higher VF (1.25 V min @ 100 mA), higher CT (2.0 pF), same 4 ns trr and 80 V VR | Marginally reduced signal fidelity in >25 MHz applications; identical ESD clamping capability | Prefer for cost-sensitive industrial designs where 0.5 dB insertion loss is acceptable |
Compared with BAV99W H6433, the 115 variant offers identical performance with standardized packaging, while MMBD7000LT1G trades minor capacitance and forward voltage penalties for broader distribution-making it viable where layout tolerance exists but not for USB 2.0-critical paths.

FAQ
Is BAV99W H6433 pin-compatible with BAV99S or BAV99U?
No. BAV99W uses SOT323 (SC74) package with 3-pin series dual configuration, while BAV99S is SOT363 (6-pin) and BAV99U is SC74 but with different internal connection mapping. Pinouts differ structurally-PCB layout must be verified per package outline drawing.
What is the maximum continuous forward current at 105 °C ambient?
At TA = 105 °C, derating curves show BAV99W supports ~125 mA continuous forward current. This is derived from the IF vs. TS graph (Sheet 5), where IF drops to 125 mA at TS = 105 °C, assuming adequate PCB copper thermal relief.
Does BAV99W H6433 meet IEC 61000-4-2 Level 4 ESD immunity?
Yes-its 80 V VR, low IR (<0.15 µA @ 70 V), and AEC-Q101 qualification confirm robustness against ±15 kV contact discharge. Actual system-level immunity depends on PCB layout and grounding, but the device meets core parametric thresholds for Level 4 compliance.
Can BAV99W H6433 replace BAT54S in a 3.3 V logic clamp?
No. BAT54S is a dual-common-cathode Schottky diode with lower VF (~320 mV) and higher CT (~10 pF); BAV99W is a series dual PN diode with higher VF (1250 mV) and lower CT (1.5 pF). Functionally incompatible due to opposite conduction topology and voltage drop profile.
