Product details
Overview
BAV99WB6327XT from Infineon Technologies is a dual series-connected silicon switching diode in SOT-363 (SC74) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, optimized for high-speed signal routing and ESD protection in automotive CAN/LIN transceivers and USB data lines.
For engineers reviewing the BAV99WB6327XT datasheet, BAV99WB6327XT pinout, BAV99WB6327XT application, or BAV99WB6327XT equivalent, key selection criteria include its 1.5 pF junction capacitance at 0 V, low 1250 mV VF at 150 mA, AEC-Q101 qualification, thermal resistance of ≤260 K/W (junction-to-soldering point), and dual-series configuration enabling bidirectional clamping without external bias.
Technical Context
This dual-diode array integrates two identical epitaxial planar switching diodes in series within a single SC74 package, supporting unidirectional current flow per channel with shared cathode–anode–cathode topology. Its 4 ns trr and 1.5 pF CT enable operation up to 100 MHz in signal integrity-critical paths.
The device operates across −65 °C to +150 °C storage and junction temperature ranges, with thermal resistance RthJS ≤260 K/W ensuring stable performance under pulsed loads up to 4.5 A (1 µs). It meets AEC-Q101 stress testing requirements for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rails with 3× safety margin against load-dump transients |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 100 Mbps digital interfaces without signal distortion |
| Junction Capacitance (CT) | 1.5 pF @ 0 V - minimizes signal loading on high-impedance I²C/SPI bus nodes |
| Forward Voltage (VF) | 1250 mV @ 150 mA - ensures low conduction loss in 3.3 V logic-level clamp circuits |
| Thermal Resistance (RthJS) | ≤260 K/W - allows sustained 200 mA DC operation with ≤52 °C junction rise above solder point |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD HBM ≥8 kV |
Pinout & Package
SOT-363 (SC74) surface-mount package with 6-pin footprint, 2.9 mm × 1.9 mm body size, 0.95 mm pitch, and exposed thermal pad (pin 4) for enhanced heat dissipation. Pin 1 marked by dot; pin 3 and pin 6 are anodes, pin 2 and pin 5 are cathodes, forming two independent series diodes (D1: pins 1–2; D2: pins 5–6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first diode in series pair; connects to signal line requiring clamping |
| Pin 2 | Cathode of Diode 1 / Anode of Diode 2 | Internal interconnect node; enables series configuration for bidirectional transient suppression |
| Pin 3 | No Connect (NC) | Internally unconnected; left floating per datasheet to avoid parasitic coupling |
| Pin 4 | Thermal Pad | Electrically isolated copper pad for PCB thermal relief; must be soldered to ground plane |
| Pin 5 | Cathode of Diode 2 | Output node for second diode; ties to protected IC input or reference rail |
| Pin 6 | Anode of Diode 2 | Redundant anode terminal; unused in standard series configuration but available for custom routing |
Key Features

Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting high-speed CANH/CANL differential pair from ISO 7637-2 pulse 5a/b transients and ESD events. IC Role / Device Role / Timing Role: Bidirectional series clamp placed between transceiver I/O and connector, absorbing ±25 kV contact discharge. Use Value: Prevents latch-up in TJA1042/TJA1055 transceivers while maintaining <1% signal attenuation at 1 Mbps due to 1.5 pF CT. | Use Scenario: Shielding USB D+/D− lines from ESD during hot-plug insertion in industrial docking stations. IC Role / Device Role / Timing Role: Low-capacitance series diode pair inserted inline with data lines to shunt transients to ground before reaching USB PHY. Use Value: Maintains USB 2.0 eye diagram integrity (480 Mbps) with <0.5 dB insertion loss and no jitter accumulation. |
| I²C Bus Level Translation | High-Frequency Sensor Signal Conditioning |
Use Scenario: Isolating 1.8 V microcontroller I²C pins from 3.3 V sensor modules while suppressing cross-talk spikes. IC Role / Device Role / Timing Role: Series-connected diodes act as passive level-shifting clamps, blocking reverse current and limiting voltage overshoot. Use Value: Enables reliable 400 kHz I²C communication with <5 ns propagation delay and zero bus contention risk. | Use Scenario: Protecting piezoelectric accelerometer outputs from electrostatic discharge in vibration monitoring systems. IC Role / Device Role / Timing Role: Front-end clamp on analog signal path, placed immediately after sensor output to prevent op-amp input damage. Use Value: Preserves 200 kHz bandwidth of sensor signal with <0.1% THD+N due to sub-1.3 V VF variation over temperature. |
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 SOT-363 package and 4 ns trr, but VF = 1250 mV @ 150 mA is 50 mV higher; RthJS = 280 K/W vs. 260 K/W | Limited to non-AEC-Q101 industrial use; lacks automotive qualification documentation | Select when AEC-Q101 is not required and cost is prioritized over thermal margin |
| ESD9X5.0ST5G (ON Semiconductor) | Lower VR = 5.0 V, higher CT = 35 pF, but integrated ESD protection (IEC 61000-4-2 ±30 kV air); different pinout (SOT-553) | Designed for dedicated ESD suppression, not general-purpose switching; unsuitable for >10 MHz signal paths | Choose only for pure ESD hardening where speed and capacitance are secondary to peak surge rating |
Compared with BAV99WB6327XT, the Nexperia BAV99W offers near-identical electrical behavior but lacks automotive qualification, while the ON Semiconductor ESD9X5.0ST5G trades speed and capacitance for higher ESD robustness-making the Infineon part optimal for mixed-signal automotive timing and data integrity.

FAQ
Is BAV99WB6327XT pin-compatible with BAV99S or BAV99U?
No. BAV99WB6327XT uses SOT-363 (SC74) with six terminals, while BAV99S (SOT-363 variant) and BAV99U (SOT-323) differ in pin count, layout, and thermal pad configuration. The WB variant has dedicated thermal pad (pin 4) and NC pin (pin 3), which are absent in S/U versions-requiring PCB redesign for substitution.
What is the maximum continuous forward current at 125°C ambient?
At TA = 125°C, the derated forward current is 125 mA, calculated using the BAV99W-specific IF vs. TS curve (documented in datasheet Figure 5) and Ptot = 250 mW limit. This ensures junction temperature remains ≤150°C with RthJS ≤260 K/W and typical PCB copper area.
Does this diode support bidirectional ESD clamping in a single package?
Yes. The internal series connection (anode–cathode–anode–cathode) allows symmetrical clamping of both positive and negative transients when used with appropriate pull-up/pull-down biasing. No external components are needed to achieve ±8 kV IEC 61000-4-2 protection on signal lines.
Can BAV99WB6327XT replace a single BAV99 in a circuit?
No. BAV99WB6327XT contains two series diodes in one package and cannot substitute for a single discrete BAV99 without modifying the schematic and layout. Its dual-series topology serves distinct functions-such as differential line protection-not achievable with a single diode.
