Product details
Overview
BAV70WE6327BTSA1 from Infineon Technologies is a silicon switching diode in SOT-323 (SC74) package with common cathode dual configuration, 80 V reverse voltage rating, 200 mA forward current, and 4 ns reverse recovery time - optimized for high-speed signal routing in automotive infotainment power management and USB data line protection circuits.
For engineers reviewing the BAV70WE6327BTSA1 datasheet, BAV70WE6327BTSA1 pinout, BAV70WE6327BTSA1 application, or BAV70WE6327BTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low 1.5 pF junction capacitance at 0 V, thermal resistance of ≤240 K/W (junction-to-soldering point), and RoHS-compliant lead-free construction.
Technical Context
This dual common-cathode diode integrates two independent high-speed PN junctions sharing a single cathode terminal, enabling compact bidirectional clamping or steering functions. Its 4 ns reverse recovery time and 1.5 pF capacitance support >100 MHz signal integrity in ESD-protected I/O paths.
The device operates across −65 °C to +150 °C storage and junction temperature ranges, with thermal resistance RthJS ≤240 K/W enabling stable performance under pulsed loads up to 0.75 A (1 s double pulse) without derating beyond TS = 90 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports rail-to-rail clamping in 24 V automotive systems without breakdown |
| Forward Current (IF) | 200 mA DC - sufficient for logic-level signal steering and low-power bias networks |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >100 MHz digital interface lines (e.g., USB 2.0) |
| Junction Capacitance (CT) | 1.5 pF @ 0 V - minimizes signal loading on high-frequency data lines |
| Thermal Resistance (RthJS) | ≤240 K/W - allows direct PCB copper pour heatsinking without external thermal vias |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements (HTOL, TC, HTRB) |
| RoHS Compliance | Pb-free package - meets EU Directive 2011/65/EU without exemptions |
Pinout & Package
BAV70WE6327BTSA1 uses the SC74 (SOT-323) surface-mount package: 2.9 mm × 1.9 mm footprint, 0.95 mm pin pitch, 1.1 mm max height, with symmetric pin 1 marking (laser-etched "A4s") and no defined orientation in tape-and-reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent anode for first diode element; routed to signal path requiring fast turn-on |
| Pin 2 | Cathode (common) | Shared cathode node for both diodes; connects to reference rail or ESD return path |
| Pin 3 | Anode 2 | Independent anode for second diode element; enables dual-direction clamping or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode topology | Reduces board space by 40% vs. discrete diode pairs while maintaining isolation between anodes |
| 4 ns trr with 10 mA/10 mA test condition | Ensures minimal switching distortion in 50 Ω transmission-line environments (e.g., CAN FD stubs) |
| 1.5 pF CT at 0 V | Preserves signal rise/fall times <1 ns in high-speed GPIO and sensor interface traces |
| RthJS ≤240 K/W | Permits continuous operation at full IF with ≤30 °C junction-to-board delta in standard FR-4 layouts |

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 |
|---|---|---|---|
| BAV99W,115 | Same SOT-323 package, identical A4s marking, but 100 V VR, 3 ns trr, 2.0 pF CT | Higher voltage margin suits 48 V industrial buses; slightly higher capacitance may affect >200 MHz signals | Select when system transients exceed 80 V but require same footprint and thermal profile |
| MMBD7000LT1G | SOT-23 package, 100 V VR, 4 ns trr, 2.5 pF CT, no AEC-Q101 qualification | Larger 3.0 mm × 1.4 mm footprint; lacks automotive qualification; higher capacitance limits RF use | Choose for cost-sensitive consumer designs where AEC-Q101 is not required and board space permits SOT-23 |
Compared with BAV99W and MMBD7000LT1G, BAV70WE6327BTSA1 offers optimal balance of automotive qualification, 80 V robustness, ultra-low capacitance, and thermal efficiency - making it preferred for space-constrained, safety-critical signal paths where 100 V rating is unnecessary.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. Continuous operation at rated 200 mA forward current requires board-level thermal design ensuring junction-to-soldering-point temperature rise stays within the ≤240 K/W limit - typically achieved with ≥10 mm² of 1 oz copper connected to Pin 2 (cathode) under standard JEDEC test conditions.
Is BAV70WE6327BTSA1 compatible with lead-free reflow profiles?
Yes. The device is qualified for standard Pb-free reflow per IPC/JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The SOT-323 package withstands thermal cycling without delamination or solder joint fracture when using SnAgCu paste and controlled ramp rates.
Can this diode be used for reverse polarity protection?
No. As a common-cathode dual diode, BAV70WE6327BTSA1 lacks an isolated cathode path required for series reverse-polarity blocking. It is designed for clamping, steering, and ESD protection - not unidirectional power path control. Use dedicated ideal diode controllers or single-anode/cathode devices for polarity protection.
How does the 4 ns reverse recovery time impact circuit layout?
The 4 ns trr demands minimized loop inductance: keep anode traces <5 mm long, use ground plane beneath Pin 2, and avoid vias in high-dI/dt paths. Layouts exceeding 10 nH stray inductance risk voltage overshoot >20 V during turn-off, potentially triggering false logic transitions in adjacent CMOS inputs.
