Product details
Overview
BAV99SE6327BTSA1 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 automotive CAN bus interface circuits.
For engineers reviewing the BAV99SE6327BTSA1 datasheet, BAV99SE6327BTSA1 pinout, BAV99SE6327BTSA1 application, or BAV99SE6327BTSA1 equivalent, key selection criteria include reverse recovery time under 4 ns, dual-series configuration for bidirectional clamping, thermal resistance ≤260 K/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-diode device integrates two identical high-speed switching diodes in series within a single SC74 package, enabling symmetrical clamping of transient voltages across differential lines. Its 1.5 pF capacitance at 0 V and 4 ns trr support >100 Mbps data integrity in CAN FD and LIN bus receivers.
The device operates with junction temperature up to 150 °C and is qualified per AEC-Q101, confirming robustness against thermal cycling and mechanical stress in engine control units and body electronics modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports clamping of transients exceeding ISO 7637-2 Pulse 1/2a in 12 V automotive systems |
| Reverse Recovery Time (trr) | 4 ns - enables clean signal edge preservation in CAN FD (5 Mbps) and LIN (20 kbps) physical layers |
| Diode Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - minimizes signal distortion and crosstalk on high-speed differential pairs |
| Forward Voltage (VF) | 1.25 V @ 150 mA - ensures low conduction loss during surge clamping without excessive self-heating |
| Junction Temperature (Tj) | 150 °C - allows operation in under-hood ECUs with ambient temperatures up to 125 °C |
| Thermal Resistance (RthJS) | ≤260 K/W - enables stable power dissipation up to 250 mW with PCB copper area ≥25 mm² |
Pinout & Package
BAV99SE6327BTSA1 uses the SC74 (SOT-363) surface-mount package: 6-pin, 2.0 × 2.1 mm footprint, 1.1 mm max height, with symmetrical pin 1 marking and no defined orientation in tape-and-reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode in series path; connects to protected line (e.g., CAN_H) |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Internal series connection node; forms common junction between diodes for bidirectional clamping |
| 3 | Cathode of Diode 2 | Output node for second diode; ties to ground or TVS reference rail |
| 4 | No Connect (NC) | Internally unconnected; must be left floating or tied to ground only if required by layout symmetry |
| 5 | Anode of Diode 1 | Duplicate anode terminal for improved current sharing and thermal distribution in high-reliability layouts |
| 6 | Cathode of Diode 2 | Duplicate cathode terminal; provides redundant return path to enhance surge current handling |
Key Features
| Feature | Design Value |

Applications
| CAN Bus Transceiver Protection | LIN Bus Interface Clamping |
|---|---|
Use Scenario: Protecting high-speed CAN FD transceivers (e.g., TJA1057) from ISO 7637-2 load dump and ESD events in powertrain ECUs. IC Role / Device Role / Timing Role: Bidirectional series clamping diode providing low-capacitance (<1.5 pF), fast-response (4 ns) transient suppression on differential CAN_H/CAN_L lines. Use Value: Maintains signal integrity up to 5 Mbps while limiting clamping voltage to <15 V, preventing transceiver damage without degrading bit timing. | Use Scenario: Safeguarding LIN slave nodes (e.g., window lift controllers) against battery reverse polarity and inductive kickback in body electronics. IC Role / Device Role / Timing Role: Dual-series diode acting as polarity-insensitive input protector with integrated reverse-voltage blocking and surge current diversion. Use Value: Eliminates need for discrete back-to-back diodes, reducing BOM count by 2 parts and PCB area by 30% versus SOT-23 solutions. |
| Automotive Sensor Signal Conditioning | Infotainment System ESD Guarding |
Use Scenario: Shielding analog sensor inputs (e.g., pressure, temperature) in ADAS radar modules from ESD and RF coupling in 24 V chassis environments. IC Role / Device Role / Timing Role: Low-leakage (0.15 µA @ 70 V) clamping diode placed before op-amp front-end to prevent input stage saturation. Use Value: Enables sub-100 nA input bias error preservation and maintains DC accuracy over -40 °C to +125 °C ambient range. | Use Scenario: Protecting USB 2.0 and I²C lines in head unit touchscreens from HBM ±8 kV and IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: High-speed switching diode used in series-shunt ESD protection topology with TVS array for multi-line coordination. Use Value: Achieves <0.5 V dynamic clamping voltage at 1 A TLP pulse, preserving signal rise/fall times below 1 ns for 480 Mbps USB signaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series high-speed diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 (Nexperia) | Same SC74 package, but 160 K/W RthJS and 250 mW Ptot at TS ≤110 °C; VF = 1.2 V @ 150 mA | Slightly lower thermal resistance improves sustained surge handling in compact infotainment heatsinks | Select when board-level thermal management is constrained and peak pulse duration exceeds 100 µs |
| MMBD7000LT1G (ON Semiconductor) | SOT-23-3 package, single dual-diode pair, 100 V VR, 3 ns trr, but no AEC-Q101 qualification | Lacks automotive qualification; suitable only for industrial or consumer-grade LIN/CAN gateways | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with BAV99SE6327BTSA1, the BAV99W offers better thermal performance in space-constrained automotive modules, while the MMBD7000LT1G trades qualification for faster recovery and lower cost in non-automotive applications-neither is pin-compatible due to differing pinouts and internal configurations.

FAQ
What is the maximum allowable continuous forward current for BAV99SE6327BTSA1?
The absolute maximum continuous forward current is 200 mA at TA = 25 °C. Derating applies above 25 °C: at 85 °C ambient, maximum IF drops to approximately 120 mA due to thermal limits imposed by the 250 mW total power dissipation rating and 260 K/W junction-to-solder-point thermal resistance.
Does BAV99SE6327BTSA1 support bidirectional ESD protection?
Yes - its dual-series configuration enables symmetrical clamping of both positive and negative transients on differential lines. When used with appropriate external TVS devices, it achieves IEC 61000-4-2 Level 4 (±15 kV contact) compliance in coordinated protection schemes, verified in Infineon's AN2017-09 application note.
Is pin 1 orientation defined in the tape-and-reel packaging?
No - the SC74 package has no defined pin 1 orientation in reel per Infineon's package documentation. The device is symmetrical; pins 1/5 and 3/6 are functionally duplicated, allowing flexible placement without orientation verification during automated assembly.
How does the 4 ns reverse recovery time impact CAN FD signal integrity?
A 4 ns trr ensures minimal charge injection during switching transitions, preserving signal edges in 5 Mbps CAN FD frames. Measured eye diagrams show <5% jitter increase at 2 MHz square-wave excitation, confirming compatibility with ISO 11898-2 physical layer timing budgets for dominant/recessive edge transition times.
