Product details
Overview
BAV99UE6327HTSA1 from Infineon Technologies is a silicon dual-series switching diode 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 signal routing and ESD protection in USB data lines and I²C bus interfaces.
For engineers reviewing the BAV99UE6327HTSA1 datasheet, BAV99UE6327HTSA1 pinout, BAV99UE6327HTSA1 application, or BAV99UE6327HTSA1 equivalent, key selection criteria include its 1.5 pF junction capacitance at 0 V, low 1250 mV VF at 150 mA, AEC-Q101 qualification, and thermal resistance of ≤260 K/W (junction-to-soldering point).
Technical Context
This dual-diode configuration connects two anodes to a common cathode (series dual), 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 solder-point-referenced thermal resistance of ≤260 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 clamping 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 USB 2.0 (480 Mbps) and I²C fast-mode+ (1 Mbps) paths |
| Junction Capacitance (CT) | 1.5 pF @ 0 V - preserves signal rise/fall times in high-frequency data lines without excessive loading |
| Forward Voltage (VF) | 1250 mV @ 150 mA - limits power loss to <188 mW per diode under peak signal conditions |
| Thermal Resistance (RthJS) | ≤260 K/W - defines minimum required PCB copper area for thermal relief when operating near Tj max |
Pinout & Package
SC74 (SOT-363) surface-mount package with 6-pin lead frame, 1.9 mm × 2.9 mm footprint, and pin 1 marked by dot or notch. Pin 1 and pin 2 are anodes; pin 3 is common cathode; pins 4–6 replicate same dual-anode/common-cathode topology for second channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Anode (Channel A) | Input terminals for bidirectional clamping; connect to protected signal line and reference rail |
| 3 | Common Cathode (Channel A) | Return path for both anodes; ties to system ground or bias voltage for clamp threshold setting |
| 4, 5 | Anode (Channel B) | Independent clamping pair for second signal path (e.g., differential pair or separate bus) |
| 6 | Common Cathode (Channel B) | Isolated return node allowing independent biasing or grounding of second channel |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive infotainment and body electronics where reliability under thermal cycling and vibration is mandatory |
| Low 1.5 pF junction capacitance | Minimizes signal attenuation and timing skew on high-speed digital lines up to 200 MHz |
| 4 ns reverse recovery time | Enables clean switching in pulse-width modulated control signals and data strobes without tail current artifacts |
| Pb-free, RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-J-STD-609A Class 3 moisture sensitivity (MSL 1) |
Applications
| USB 2.0 Data Line Protection | I²C Bus Level Shifting |
|---|---|
Use Scenario: Protecting D+ and D− lines from ESD events and voltage transients during hot-plug insertion. IC Role / Device Role: Bidirectional clamping diode array providing ±15 kV HBM ESD immunity while preserving signal integrity. Use Value: Maintains 480 Mbps data rate with <0.5% jitter increase due to 1.5 pF CT and 4 ns trr. | Use Scenario: Translating logic levels between 3.3 V microcontroller and 5 V sensor on shared SDA/SCL lines. IC Role / Device Role: Passive level shifter using forward-biased diode drop to establish intermediate voltage thresholds. Use Value: Enables interoperability without active translators; 1250 mV VF at 150 mA ensures stable 2.05 V mid-rail under load. |
| Automotive CAN FD Node Interface | Industrial RS-485 Receiver Input Clamp |
Use Scenario: Guarding CAN FD transceiver inputs against load-dump-induced surges and ISO 7637-2 pulses. IC Role / Device Role: Front-end transient voltage suppressor with 80 V VR rating and AEC-Q101 validation. Use Value: Survives 12 V system load dump (up to 35 V for 400 ms) without degradation; RthJS ≤260 K/W sustains operation at 105 °C ambient. | Use Scenario: Limiting input voltage excursions on RS-485 receivers exposed to field wiring faults and lightning-induced surges. IC Role / Device Role: Low-capacitance overvoltage clamp placed before receiver input to prevent latch-up. Use Value: 1.5 pF CT avoids degrading 10 Mbps signal edges; 80 V VR withstands common-mode transients up to ±25 V. |
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 SC74 package, but common-cathode configuration with lower RthJS (≤160 K/W); VF = 1200 mV @ 150 mA | Better thermal performance for higher ambient environments; identical pinout and clamping function | Select when board-level thermal management is limited and junction temperature margin is critical |
| MMBD7000LT1G (ON Semiconductor) | SOT-23-6 package, series dual anode/cathode, VF = 1000 mV @ 100 mA, trr = 4 ns, CT = 2.5 pF | Higher capacitance reduces suitability for >50 MHz signals; same AEC-Q101 qualification | Choose only if SC74 footprint compatibility is not required and lower forward drop outweighs bandwidth penalty |
Compared with BAV99UE6327HTSA1, BAV99W offers superior thermal dissipation for high-power-density layouts, while MMBD7000LT1G trades 1.0 pF higher capacitance for marginally lower VF-making the Infineon part optimal for speed-critical, thermally constrained automotive and industrial interfaces.

FAQ
What is the pin configuration of BAV99UE6327HTSA1?
BAV99UE6327HTSA1 uses a dual-series configuration in SC74 package: pins 1 and 2 are anodes of Channel A, pin 3 is their common cathode; pins 4 and 5 are anodes of Channel B, pin 6 is their common cathode. This allows independent bidirectional clamping on two signal paths.
Is BAV99UE6327HTSA1 suitable for automotive applications?
Yes-BAV99UE6327HTSA1 is qualified to AEC-Q101 standards, tested for temperature cycling, humidity, mechanical shock, and ESD robustness. Its 150 °C max junction temperature and ≤260 K/W RthJS make it appropriate for under-hood and infotainment module designs.
How does the 1.5 pF junction capacitance affect high-speed signal integrity?
At 1.5 pF, the diode adds negligible capacitive loading to signal lines-preserving rise/fall times below 1 ns for edge rates typical in USB 2.0 and I²C fast-mode+. Measured trr of 4 ns further prevents charge trapping that could distort multi-Mbps data transitions.
Can BAV99UE6327HTSA1 replace single-diode packages like BAV99 in existing designs?
No-BAV99UE6327HTSA1 is a 6-pin dual-channel device in SC74, whereas standard BAV99 is a 3-pin SOT-23 single-channel part. Direct replacement requires PCB layout revision to accommodate the larger footprint and dual-channel connectivity.
