Product details
Overview
BAV70WH6327XTSA1 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 I/O protection circuits.
For engineers reviewing the BAV70WH6327XTSA1 datasheet, BAV70WH6327XTSA1 pinout, BAV70WH6327XTSA1 application, or BAV70WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low 1.5 pF junction capacitance at 0 V, thermal resistance of ≤260 K/W (junction-to-soldering point), and guaranteed 85 V breakdown voltage at 100 µA test current.
Technical Context
This dual diode integrates two identical high-speed switching elements sharing a common cathode terminal, enabling compact bidirectional ESD/clamp protection or logic-level signal steering without cross-conduction risk. Its 4 ns trr and low VF (1.25 V max at 150 mA) support clean edge transitions in 10–50 MHz digital interfaces.
The SC74 package provides six terminals with pins 1/2/3 assigned to anode1/cathode/anode2, delivering superior thermal performance (RthJS ≤260 K/W) versus SOT-23 variants-critical for sustained 200 mA operation in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports rail-to-rail clamping in 24 V automotive systems without avalanche conduction |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation in >25 MHz clock/data lines and PWM edge detection |
| Junction Capacitance (CT) | 1.5 pF @ 0 V - minimizes signal loading on high-impedance analog inputs and RF paths |
| Forward Voltage (VF) | 1.25 V max @ 150 mA - reduces power loss and self-heating during continuous I/O line protection |
| Thermal Resistance (RthJS) | ≤260 K/W - allows 200 mA DC operation up to 85°C board temperature in sealed enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive body control, lighting, and sensor interface applications |
Pinout & Package
BAV70WH6327XTSA1 uses the SC74 (SOT-363) surface-mount package: 2.9 mm × 1.9 mm footprint, 1.1 mm height, six-terminal leadframe with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input node for first diode path; connects to protected signal line or switch output |
| Pin 2 | Cathode (common) | Shared return path for both diodes; must be routed to stable reference (e.g., GND or VCC) |
| Pin 3 | Anode 2 | Input node for second diode path; enables dual-rail clamping or signal steering |
| Pin 4 | No connection | Internally unconnected; left floating per design-no PCB trace required |
| Pin 5 | No connection | Internally unconnected; left floating per design-no PCB trace required |
| Pin 6 | No connection | Internally unconnected; left floating per design-no PCB trace required |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual configuration | Enables simultaneous clamping of two independent signals to same reference without shared anode coupling |
| 4 ns reverse recovery time | Preserves signal integrity in high-frequency data buses (e.g., CAN FD physical layer, LIN transceivers) |
| 1.5 pF junction capacitance | Minimizes timing skew and crosstalk when placed on differential pairs or high-Z sensor outputs |
| AEC-Q101 qualification | Validated for 150°C junction operation and 1000-hour HTOL stress-meets automotive module reliability requirements |

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 SC74 package, but 100 V VR rating and 3 ns trr; VF = 1.25 V @ 150 mA | Better suited for 48 V industrial systems; slightly faster but higher leakage (0.5 µA @ 70 V) | Select when higher reverse margin or sub-4 ns timing is required; verify IR impact on low-power sleep modes. |
| MMBD7000LT1G | SOT-23-3 package, single common-cathode dual diode, 70 V VR, 4 ns trr, VF = 1.25 V @ 150 mA | Limited to single-channel protection; smaller footprint but higher RthJA (400 K/W) | Choose for cost-sensitive consumer designs where thermal budget permits and dual-rail clamping is not needed. |
Compared with BAV70WH6327XTSA1, BAV99W offers higher voltage margin and faster switching but increased leakage, while MMBD7000LT1G sacrifices thermal performance and dual-channel flexibility for lower cost and size-making BAV70WH6327XTSA1 optimal for thermally constrained AEC-Q101 automotive modules requiring matched dual-path protection.

FAQ
What is the maximum junction temperature and how does it affect continuous operation?
The BAV70WH6327XTSA1 has a maximum junction temperature of 150°C. At ambient temperatures up to 85°C, its SC74 package's RthJS ≤260 K/W allows full 200 mA DC forward current without derating. Exceeding this thermal limit triggers irreversible degradation of the PN junction, so board layout must ensure adequate copper area under the exposed pad for heat dissipation.
Is pin 1 orientation defined in the tape-and-reel packaging?
No-Infineon specifies that symmetric SC74 packages like BAV70WH6327XTSA1 have no defined pin 1 orientation in reel; the device may be placed either way. Designers must rely on the molded dot or laser marking on the top surface for orientation verification during placement, and confirm alignment using optical inspection or fiducial-based vision systems.
How does the common-cathode configuration impact circuit layout compared to discrete diodes?
The shared cathode eliminates the need for two separate ground-return traces, reducing PCB area and parasitic inductance. However, it requires both anodes to reference the same clamping rail-preventing independent voltage rail protection. Layout must avoid routing high-noise signals near the common cathode trace to prevent coupling between protected channels.
Can BAV70WH6327XTSA1 replace BAV70W in existing designs without modification?
Yes-BAV70WH6327XTSA1 is the commercial-grade tape-and-reel variant of the BAV70W, sharing identical electrical specs, SC74 package dimensions, and pinout. The "H6327" suffix denotes Infineon's standard packaging format (7-inch reel, 3,000 pcs), and "XTSA1" indicates RoHS-compliant lead-free finish; no schematic or layout changes are needed for drop-in replacement.
