Product details
Overview
BAV70UE6327 from Infineon Technologies is a silicon switching diode in SOT363 (SC74) package with common cathode dual configuration, 80 V reverse voltage rating, 200 mA forward current, and 4 ns reverse recovery time-designed for high-speed signal routing in automotive body control modules and USB port protection circuits.
For engineers reviewing the BAV70UE6327 datasheet, BAV70UE6327 pinout, BAV70UE6327 application, or BAV70UE6327 equivalent, key selection criteria include its dual-common-cathode topology, low 1.25 V forward voltage at 150 mA, AEC-Q101 qualification, and thermal resistance of ≤260 K/W junction-to-soldering-point.
Technical Context
This dual diode shares a common cathode terminal, enabling compact bidirectional clamping or steering in signal path protection. Its 4 ns trr and 1.5 pF capacitance at 0 V support >100 MHz switching in ESD-protected data lines.
Rated for 150 °C junction temperature and qualified per AEC-Q101, it sustains operation under automotive thermal transients while maintaining <0.15 µA reverse leakage at 70 V and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression without breakdown |
| Forward Current (IF) | 200 mA - sufficient for logic-level signal clamping and I²C bus termination |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >100 MHz digital signal paths |
| Diode Capacitance (CT) | 1.5 pF at 0 V - minimizes signal distortion in high-speed USB 2.0 and CAN FD interfaces |
| Junction Temperature (Tj) | 150 °C - ensures reliability in under-hood ECUs and power distribution units |
| Thermal Resistance (RthJS) | ≤260 K/W - allows sustained 200 mA operation with ≤33 °C solder point rise above ambient |
Pinout & Package
BAV70UE6327 uses the SC74 (SOT363) surface-mount package: 6-pin, 2.9 mm × 1.9 mm footprint, 1.1 mm max height, with pin 1 marked by a dot or bevelled corner. Pin 1 and pin 2 are anode terminals; pin 3 is common cathode; pins 4–6 are unused (NC) per Infineon's SC74 outline drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first high-speed clamping path; routed to protected signal line |
| Pin 2 | Anode of Diode 2 | Independent input node for second clamping path; supports dual-rail protection |
| Pin 3 | Common Cathode | Shared return path to ground or bias rail; reduces PCB trace count vs. discrete diodes |
| Pins 4–6 | No Connect | Internal die paddle tie-off only; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive applications including engine control, lighting, and infotainment systems |
| Common Cathode Dual Configuration | Reduces component count and board area by 50% versus two SOT23 diodes in shared-return layout |
| Low Reverse Leakage (0.15 µA @ 70 V) | Minimizes standby power loss in always-on vehicle networks like LIN or CAN partial networking |
| RoHS Compliant / Pb-Free | Meets EU Directive 2011/65/EU and automotive ELV requirements for end-of-life recyclability |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,115 (Nexperia) | Same SOT363 package, but 100 V VR and 3 ns trr; VF = 1.25 V @ 150 mA | Higher VR margin suits 48 V mild-hybrid systems; faster trr benefits LVDS interfaces | Select when >80 V standoff or sub-4 ns timing is required; verify layout compatibility with Nexperia's pin 1 marking |
| MMBD7000LT1G (ON Semiconductor) | SOT23-3 package, single common-cathode dual diode, 70 V VR, 4 ns trr, VF = 1.25 V @ 150 mA | Larger footprint and no pin 3 cathode symmetry; requires separate cathode routing | Choose only if SOT23-3 is already standardized in design; not drop-in due to different pinout and thermal profile |
Compared with BAV70UE6327, BAV99,115 offers higher voltage margin and slightly faster switching but identical thermal performance, while MMBD7000LT1G sacrifices layout efficiency and thermal resistance for legacy package compatibility.

FAQ
What is the maximum continuous forward current for BAV70UE6327 at 100 °C ambient?
At TA = 100 °C, the maximum continuous forward current is derated to 125 mA per diode, based on the IF vs. TS curve for BAV70S in the datasheet and the device's ≤260 K/W RthJS. This ensures junction temperature remains below 150 °C with standard PCB copper area.
Is BAV70UE6327 pin-compatible with BAV70W or BAV70S?
No-BAV70UE6327 uses SOT363 (SC74), while BAV70W is SOT323 and BAV70S is also SOT363 but with different thermal derating limits. Though BAV70S shares the same package and pinout, BAV70UE6327 has distinct marking (A4s) and is rated for TS ≤ 85 °C, requiring layout verification before substitution.
Does BAV70UE6327 support bidirectional ESD protection?
Yes-its dual common-cathode structure allows each anode to clamp positive transients to the shared cathode (ground or bias rail), while reverse-biased conduction handles negative transients. This provides full bidirectional protection without external bias components, validated per IEC 61000-4-2 Level 4 testing.
Can BAV70UE6327 be used in 48 V automotive systems?
No-its 80 V VR rating provides only 1.67× margin over 48 V nominal, insufficient for load dump transients (ISO 7637-2 Pulse 5a: up to 60 V for 400 ms). For 48 V systems, use BAV99,115 (100 V VR) or BAT54 series with ≥100 V VR and AEC-Q101 qualification.
