Product details
Overview
BAT6406WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SCD80 package configured as a common anode dual diode, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time, used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT6406WE6327HTSA1 datasheet, BAT6406WE6327HTSA1 pinout, BAT6406WE6327HTSA1 application, or BAT6406WE6327HTSA1 equivalent, key selection criteria include its 370 mV forward voltage at 30 mA, 4 pF capacitance at 1 V, AEC-Q101 qualification, RoHS-compliant lead-free packaging, and thermal resistance of 155 K/W (junction-to-soldering point).
Technical Context
This dual common-anode Schottky diode enables compact bidirectional clamping and rail-to-rail signal protection without cross-conduction risk. Its integrated diffused guard ring ensures stable breakdown behavior and ESD robustness up to ±8 kV (HBM), while the low 370 mV VF at 30 mA minimizes insertion loss in high-frequency analog front-ends.
The device operates across –55 °C to 150 °C junction temperature range and supports pulsed forward currents up to 800 mA (10 ms). Its 4 pF junction capacitance at 1 V and 5 ns trr support >100 MHz signal integrity in RF detector and mixer bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Withstands transient overvoltage up to 40 V without breakdown in clamp or protection paths. |
| Forward Current (IF) | 250 mA - Continuous DC current handling capability per diode element under TS ≤ 111 °C. |
| Forward Voltage (VF) | 370 mV @ 30 mA - Low conduction loss preserves signal amplitude in precision bias and metering applications. |
| Reverse Recovery Time (trr) | 5 ns - Enables fast switching in RF envelope detection and high-speed digital signal clamping. |
| Junction Capacitance (CT) | 4 pF @ 1 V, 1 MHz - Minimizes capacitive loading on high-impedance sensor nodes and RF inputs. |
| Thermal Resistance (RthJS) | 155 K/W - Supports reliable power dissipation in space-constrained SCD80 footprint with solder-point cooling. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics use including engine control, body electronics, and ADAS sensors. |
Pinout & Package
Package: SCD80 - ultra-compact surface-mount plastic package (2.5 × 1.45 × 0.9 mm), lead-free, RoHS-compliant, optimized for automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky junction; connects to protected signal line or bias source. |
| Pin 2 | Cathode (common) | Shared cathode node; ties both diodes to reference rail (e.g., VCC or ground) for clamping. |
| Pin 3 | Anode 2 | Input terminal for second Schottky junction; enables dual-directional or differential clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables symmetrical bidirectional clamping to a single rail without external node coupling. |
| Integrated diffused guard ring | Improves voltage stability and ESD immunity by suppressing edge breakdown and leakage drift. |
| Low forward voltage (370 mV @ 30 mA) | Reduces power loss and self-heating in battery-powered sensor interfaces and portable instrumentation. |
| AEC-Q101 qualification | Validates reliability for automotive under-hood and cabin applications with extended temperature cycling. |
| ESD-sensitive handling requirement | Mandates static-safe assembly practices due to ±8 kV HBM rating-prevents latent damage during PCB handling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Single common-cathode diode in SCD80; 30 V VR, 350 mV VF @ 30 mA, 3 pF CT | Lacks dual-diode redundancy; suited for unidirectional clamping only | Select when space allows separate devices or single-rail protection suffices |
| BAT54CW | Common-cathode dual in SOT-323; 30 V VR, 380 mV VF @ 10 mA, 10 pF CT | Higher capacitance degrades RF performance; lower VR limits automotive transients | Prefer for cost-sensitive consumer designs where 30 V rating and 10 pF are acceptable |
Compared with BAR63-02W and BAT54CW, BAT6406WE6327HTSA1 delivers higher 40 V transient tolerance, lower 4 pF capacitance for RF integrity, and AEC-Q101 validation-making it optimal for automotive and high-frequency signal protection where dual common-anode topology and robustness are critical.

FAQ
What is the maximum allowable junction temperature for BAT6406WE6327HTSA1?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 stress testing. Operation above this limit risks permanent degradation of the Schottky barrier and increased reverse leakage. Derating is required above ambient temperatures where power dissipation exceeds the 155 K/W thermal resistance limit.
Does BAT6406WE6327HTSA1 support bidirectional signal clamping?
Yes-it uses a common-anode dual configuration, allowing simultaneous clamping of two independent signal lines to the same cathode reference rail (e.g., VCC or GND). This enables true bidirectional voltage limiting without cross-talk or shared anode impedance.
Is BAT6406WE6327HTSA1 compatible with lead-free reflow profiles?
Yes-the SCD80 package is Pb-free and RoHS-compliant, qualified for standard JEDEC J-STD-020D reflow profiles with peak temperatures up to 260 °C. The device withstands three reflow cycles without parameter shift or delamination.
How does the integrated guard ring improve reliability?
The diffused guard ring suppresses edge electric field crowding, preventing premature avalanche breakdown and reducing leakage current drift over temperature and time. It enhances long-term stability in automotive environments subject to thermal cycling and humidity exposure.
