Product details
Overview
BAV70T E6327 from Infineon Technologies is a silicon double diode in common-cathode configuration, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-optimized for high-speed switching in signal routing and clamp protection circuits in automotive body control modules.
For engineers reviewing the BAV70T E6327 datasheet, BAV70T E6327 pinout, BAV70T E6327 application, or BAV70T E6327 equivalent, key selection criteria include reverse recovery time under 5 ns, thermal resistance ≤240 K/W (SC74 package), AEC-Q101 qualification, and common-cathode dual-diode topology for compact bidirectional clamping.
Technical Context
This dual diode integrates two identical high-speed switching elements sharing a single cathode terminal, enabling symmetrical clamping or steering functions without external node coupling. Its 1.5 pF junction capacitance at 0 V and 1 MHz supports RF-adjacent signal integrity in CAN transceiver I/O protection and USB data line transient suppression.
The device operates with a maximum junction temperature of 150 °C and exhibits low leakage-≤0.15 µA at 70 V and 25 °C-ensuring stable performance in thermally constrained automotive ECUs and industrial sensor interfaces where ambient temperatures exceed 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient clamping with 3× safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation in >100 MHz digital signal paths and fast-switching logic buffers |
| Junction Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - minimizes signal distortion in high-frequency data lines (e.g., LIN, SENT) |
| Forward Voltage (VF) | 1.25 V @ 150 mA - limits power loss to <188 mW during active clamping in 5 V logic interfaces |
| Thermal Resistance (RthJS) | 240 K/W - allows 250 mW total dissipation with ≤60 K rise above solder point in SC74 footprint |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥8 kV) |
Pinout & Package
BAV70T E6327 is housed in an SC74 (SOT-363) surface-mount package measuring 2.9 mm × 1.9 mm × 1.1 mm, with six terminals in a symmetrical layout and no defined Pin 1 orientation in tape-and-reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input node for first diode path; routed to signal line requiring unidirectional clamping |
| 2 | Cathode (common) | Shared return path for both diodes; connects to reference rail (e.g., VCC or GND) |
| 3 | Anode 2 | Input node for second diode path; used for complementary or differential clamping |
| 4 | No Connect | Internally isolated; left floating or tied to cathode for mechanical stability only |
| 5 | No Connect | Internally isolated; no electrical function; may be grounded for EMI reduction |
| 6 | No Connect | Internally isolated; unused terminal per SC74 mechanical outline |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual diode | Enables compact bidirectional clamping with single reference connection-reduces PCB area by 40% vs. discrete pair |
| 4 ns reverse recovery | Supports clean edge transitions in 10–100 MHz clock distribution and serial bus termination |
| 1.5 pF junction capacitance | Maintains signal integrity on 50 Ω traces up to 500 MHz without measurable insertion loss |
| AEC-Q101 qualified | Validated for 15-year field life in automotive underhood environments (−40 °C to +125 °C ambient) |
| Pb-free RoHS-compliant | Meets JEDEC J-STD-020 reflow profile; compatible with leaded and lead-free assembly processes |
Applications
| Automotive LIN Bus Protection | Industrial Sensor Signal Clamping |
|---|---|
Use Scenario: Protects LIN transceiver I/O pins against load-dump transients and ESD events in door module ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp limiting input swing to ±15 V while preserving 19.2 kbps signal fidelity.

IC Role / Device Role / Timing Role: Fast-acting forward conduction path shunting surge energy before op-amp input stage damage occurs. Use Value: Limits overvoltage to <1.3 V above rail using VF = 1.25 V @ 150 mA, ensuring ADC input stays within safe range. |
| USB 2.0 Data Line ESD Suppression | High-Speed Logic Level Translation |
Use Scenario: Placed inline on D+ and D− lines to absorb ±8 kV HBM ESD pulses without signal degradation. IC Role / Device Role / Timing Role: Low-capacitance (1.5 pF) clamping diode referenced to 3.3 V rail, maintaining eye diagram integrity.

IC Role / Device Role / Timing Role: Dual-anode configuration provides independent level-shift paths for TX/RX signals sharing ground reference. Use Value: Enables sub-5 ns propagation delay matching between channels, critical for setup/hold timing in 100 MHz SPI links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,115 (Nexperia) | Same SC74 package, but 60 V VR rating and 3 ns trr; VF = 1.25 V @ 150 mA matches closely | Limited to 12 V systems; unsuitable for 24 V automotive load-dump scenarios requiring ≥80 V standoff | Select when lower-cost sourcing is prioritized and system max voltage ≤60 V |
| MMBD7000LT1G (ON Semiconductor) | SC70-6 package; 100 V VR, 4 ns trr, but CT = 2.5 pF - 67% higher capacitance than BAV70T E6327 | Higher capacitance degrades signal integrity above 200 MHz; not recommended for USB 2.0 or high-speed logic | Choose only if board space allows larger SC70 footprint and RF performance is non-critical |
Compared with BAV99,115 and MMBD7000LT1G, BAV70T E6327 uniquely balances 80 V standoff, 4 ns speed, and 1.5 pF capacitance in SC74-making it the only option qualified for AEC-Q101 24 V automotive clamping with sub-500 MHz signal fidelity.

FAQ
What is the maximum continuous forward current rating for BAV70T E6327?
The absolute maximum DC forward current is 200 mA at TA = 25 °C. Derating applies above 25 °C ambient: at 85 °C, maximum IF drops to 125 mA per diode due to thermal limits imposed by the SC74 package's 240 K/W junction-to-solder-point resistance and 150 °C max junction temperature.
Is BAV70T E6327 pin-compatible with BAV70S or BAV70U variants?
No-BAV70T E6327 uses the SC74 (SOT-363) package with six terminals, while BAV70S is SOT-363 but marked A4s and specified for TS ≤ 85 °C, and BAV70U is SC74 but rated for TS ≤ 90 °C. Pin numbering and internal connectivity match, but thermal derating curves and power handling differ significantly.
Does BAV70T E6327 support bidirectional ESD protection?
Not inherently-its common-cathode configuration supports unidirectional clamping from anode to cathode. For bidirectional protection, two devices are required: one with cathode tied to VCC (for negative transients) and another with cathode tied to GND (for positive transients), or use a dedicated bidirectional TVS array.
Can BAV70T E6327 replace BAT54S in a 3.3 V logic interface?
Yes, with verification: both are common-cathode dual Schottky-like silicon diodes in SC74, but BAV70T E6327 has higher VR (80 V vs. 30 V) and slower trr (4 ns vs. ~1 ns for BAT54S). It is suitable where voltage margin matters more than ultrafast switching-e.g., 3.3 V I/O clamping with 12 V fault tolerance.
