Product details
Overview
BAV70SE6327BTSA1 from Infineon Technologies is a silicon switching diode in common-cathode dual configuration housed 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 clamping in automotive body electronics and industrial sensor interfaces.
For engineers reviewing the BAV70SE6327BTSA1 datasheet, BAV70SE6327BTSA1 pinout, BAV70SE6327BTSA1 application, or BAV70SE6327BTSA1 equivalent, key selection criteria include reverse recovery time under 5 ns, dual-diode thermal coupling in shared cathode topology, AEC-Q101 qualification, and low capacitance (1.5 pF) for RF-sensitive signal paths.
Technical Context
This dual common-cathode diode integrates two independent PN junctions sharing a single cathode terminal, enabling compact bidirectional clamping or steering functions without discrete interconnects. Its 4 ns trr and 1.5 pF CT support >100 MHz signal integrity in ESD protection and data line conditioning circuits.
Thermal resistance RthJS of ≤260 K/W (SC74 package) allows sustained 200 mA operation at TS ≤85°C, with junction temperature limited to 150°C and storage range spanning −65°C to +150°C-meeting automotive under-hood ambient requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transients with 3× safety margin |
| Forward Current (IF) | 200 mA - enables direct drive of logic-level inputs or LED indicators without external buffering |
| Reverse Recovery Time (trr) | 4 ns - ensures minimal switching loss and signal distortion in >50 MHz digital I/O lines |
| Diode Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - preserves bandwidth in USB 2.0, CAN FD, and LIN bus termination networks |
| Junction Temperature (Tj) | 150 °C - validated for continuous operation in engine control unit (ECU) and lighting module environments |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
BAV70SE6327BTSA1 uses the SC74 (SOT-363) surface-mount package: six-pin, dual-row, common-cathode layout with pin 1 marked by dot or bevel. Package dimensions are 2.9 mm × 1.9 mm × 1.1 mm (L × W × H), compatible with standard reflow profiles and automated pick-and-place.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first clamping path; routed to signal line requiring transient suppression |
| Pin 2 | Cathode (Common) | Shared return path for both diodes; connects directly to system ground or reference plane |
| Pin 3 | Anode of Diode 2 | Independent input node for second signal channel or bidirectional interface |
| Pin 4 | No Connect | Internally unconnected; left floating or tied to ground only if required for mechanical stability |
| Pin 5 | No Connect | Internally unconnected; no electrical function; avoids unintended parasitic coupling |
| Pin 6 | No Connect | Internally unconnected; maintains package symmetry and thermal uniformity during soldering |
Key Features
| Feature | Design Value |
|---|---|

| 4 ns reverse recovery time | Enables clean edge transitions in 10–100 MHz clock distribution and serial data lines (e.g., SPI, I²C) |
| 1.5 pF junction capacitance | Minimizes loading on high-impedance analog sensor outputs (e.g., thermistor bridges, Hall sensors) |
| AEC-Q101 qualification | Validates performance across −40°C to +125°C operating range with zero early-life failure in automotive production |
Applications
| Automotive LIN Bus Protection | Industrial Analog Sensor Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,115 (Nexperia) | Same SC74 package, but 70 V VR and 3 ns trr; VF = 1.25 V @ 150 mA | Slightly lower reverse voltage margin; preferred where sub-3 ns timing dominates over 80 V robustness | Select when optimizing for ultra-fast edge rates in RF front-end switching rather than automotive transient immunity |
| MMBD7000LT1G (ON Semiconductor) | SC70-6 package, 100 V VR, 6 ns trr, VF = 1.25 V @ 150 mA | Larger VR margin but slower recovery; higher RthJS (≤300 K/W) limits power density | Choose for legacy designs requiring 100 V standoff in non-automotive industrial controls with relaxed speed requirements |
Compared with BAV70SE6327BTSA1, BAV99 offers faster switching at reduced voltage rating, while MMBD7000LT1G trades speed for higher VR and wider availability-but neither matches its AEC-Q101 qualification and 260 K/W thermal resistance in SC74.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150°C, and the device is rated for continuous operation up to this limit when mounted on a PCB with adequate copper pour and thermal vias. Derating begins above TS = 85°C for the SC74 package, with forward current linearly reduced to zero at 150°C junction temperature per the IF vs. TS curves in the datasheet.
Is BAV70SE6327BTSA1 suitable for bidirectional ESD protection on differential pairs?
Yes-it supports bidirectional clamping when configured with one anode tied to the positive line and the other to the negative line, sharing the common cathode to ground. Its matched 4 ns trr and 1.5 pF CT ensure symmetrical response across both polarities, making it appropriate for USB 2.0, RS-485, and CAN FD differential bus protection.
Does the SC74 package have defined pin 1 orientation in tape-and-reel delivery?
No-per Infineon's package documentation, symmetric types like BAV70SE6327BTSA1 do not define pin 1 orientation in reel; orientation must be verified optically or electrically before placement. The marking "A4s" appears adjacent to pin 1, and the physical dot or bevel identifies pin 1 on individual units.
How does the common-cathode configuration affect thermal performance compared to discrete diodes?
The shared cathode reduces total thermal resistance by eliminating separate cathode bond wires and die attach layers, achieving RthJS ≤260 K/W-25% lower than two discrete SOT-23 diodes. This improves power dissipation efficiency and enables tighter thermal coupling for balanced current sharing in parallel clamping configurations.
