Product details
Overview
BAT6404WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SCD80) package configured as a common-cathode dual diode, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time, used in low-loss clamping and bias isolation circuits in automotive metering and industrial sensor interfaces.
For engineers reviewing the BAT6404WH6327XTSA1 datasheet, BAT6404WH6327XTSA1 pinout, BAT6404WH6327XTSA1 application, or BAT6404WH6327XTSA1 equivalent, key selection criteria include its 4 pF typical junction capacitance at 1 V, 370 mV forward voltage at 30 mA, AEC-Q101 qualification, RoHS-compliant Pb-free construction, and thermal resistance of 155 K/W (junction-to-soldering point).
Technical Context
This dual common-cathode Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports fast-switching operation with sub-5 ns reverse recovery. Its low VF (370 mV typ. @ 30 mA) and low CT (4 pF typ. @ 1 V) enable high-efficiency signal clamping in precision analog front-ends.
The device operates across –55 °C to +150 °C junction temperature range and is qualified per AEC-Q101 for automotive applications. Thermal design must account for RthJS = 155 K/W and derated IF = 200 mA at TS = 111 °C for the BAT64-04W variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum DC blocking capability before breakdown; suitable for 24 V automotive supply rail protection. |
| Forward Current (IF) | 250 mA - Continuous DC current rating; derates to 200 mA at case temperature of 111 °C. |
| Reverse Recovery Time (trr) | 5 ns - Enables use in >10 MHz clamping and RF detector circuits without switching loss penalty. |
| Junction Capacitance (CT) | 4 pF @ 1 V - Low capacitance preserves signal integrity in high-frequency bias networks and ESD protection paths. |
| Forward Voltage (VF) | 370 mV @ 30 mA - Minimizes conduction loss in low-voltage bias and level-shifting applications. |
| Thermal Resistance (RthJS) | 155 K/W - Defines junction-to-solder-point thermal path; critical for PCB copper pour sizing in thermally constrained layouts. |
Pinout & Package
Package: SOT-323 (SCD80), surface-mount, 3-terminal plastic package with cathode-marked lead 3; dual diode configuration with shared cathode (Pin 3), anodes on Pins 1 and 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first diode; connects to signal source requiring clamping or isolation. |
| Pin 2 | Anode 2 | Input terminal for second diode; enables dual-path protection or differential biasing. |
| Pin 3 | Common Cathode | Shared output node tied to reference (e.g., ground or bias rail); defines return path for both diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual configuration | Enables compact dual-channel clamping or bidirectional ESD protection without discrete layout duplication. |
| Diffused guard ring | Suppresses premature edge breakdown under high dv/dt, improving reliability in noisy automotive environments. |
| AEC-Q101 qualification | Validated for automotive under-hood and instrument cluster use, including temperature cycling and HTRB stress testing. |
| Pb-free (RoHS compliant) | Meets EU RoHS Directive 2011/65/EU; compatible with lead-free reflow profiles up to 260 °C peak. |
Applications
| Automotive Instrument Clamping | Industrial Sensor Bias Isolation |
|---|---|
Use Scenario: Protecting analog inputs of digital car dashboards from transients induced by alternator load dumps or relay switching. IC Role / Device Role / Timing Role: Signal clamping diode limiting input voltage to ±0.5 V beyond rail, preserving ADC front-end integrity. Use Value: 5 ns trr prevents latch-up during fast spikes; 40 V VR withstands ISO 7637-2 Pulse 1/2a surges. | Use Scenario: Isolating bias voltage for 4–20 mA current-loop sensors in PLC analog input modules. IC Role / Device Role / Timing Role: DC bias isolation diode preventing backfeed between sensor excitation and signal conditioning stages. Use Value: 370 mV VF minimizes offset error; common-cathode layout simplifies dual-sensor channel routing. |
| RF Detector Input Protection | Low-Voltage Logic-Level Shifting |
Use Scenario: Safeguarding RF envelope detector inputs in wireless telemetry receivers operating at 868 MHz ISM band. IC Role / Device Role / Timing Role: High-speed AC coupling and transient suppression diode placed before detector diode. Use Value: 4 pF CT avoids resonant detuning; 5 ns trr ensures minimal distortion of envelope waveform. | Use Scenario: Level shifting between 1.8 V microcontroller GPIO and 3.3 V analog switch control lines in portable medical devices. IC Role / Device Role / Timing Role: Unidirectional logic-level translator using forward conduction drop to reduce high-level voltage. Use Value: 320 mV VF @ 1 mA enables precise 1.8 → 3.3 V translation; SOT-323 footprint saves board space. |
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-anode SOT-323 Schottky; 30 V VR, 250 mA IF, 3 pF CT, no AEC-Q101 qualification. | Lacks dual-diode integration and automotive qualification; suited for non-automotive consumer clamping only. | Select when single-diode function suffices and AEC-Q101 is not required. |
| BAT54CW | Common-cathode dual Schottky in SOT-323; 30 V VR, 200 mA IF, 10 pF CT, no AEC-Q101. | Higher capacitance limits RF use; lower VR restricts 24 V system compatibility. | Choose for cost-sensitive industrial designs where 30 V rating and 10 pF are acceptable. |
Compared with BAR63-02W and BAT54CW, BAT6404WH6327XTSA1 uniquely combines AEC-Q101 compliance, 40 V rating, and 4 pF capacitance in a dual-common-cathode SOT-323 package-making it the only option qualified for automotive metering and high-frequency industrial sensing where reliability and speed are jointly critical.

FAQ
What is the maximum allowable soldering temperature profile for BAT6404WH6327XTSA1?
The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature of 260 °C for ≤ 30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C shall be 60–150 seconds. Exceeding these limits risks delamination or bond wire failure.
Does BAT6404WH6327XTSA1 support bidirectional ESD protection?
No-it is a unidirectional Schottky diode pair with common cathode; effective only for positive transients relative to cathode. For bidirectional ESD protection, a TVS array like ESD204 or dual-rail clamp topology is required.
Can BAT6404WH6327XTSA1 replace BAT54CW in existing PCB layouts?
Yes-both use identical SOT-323 footprints and share pin 1/anode 1, pin 2/anode 2, pin 3/common cathode assignments. However, BAT6404WH6327XTSA1's higher 40 V VR and lower 4 pF CT may require review of transient energy handling and RF matching in the circuit.
Is thermal pad connection required for BAT6404WH6327XTSA1 in high-power operation?
No-the SOT-323 (SCD80) package has no thermal pad. Thermal performance relies entirely on PCB copper area connected to Pin 3 (cathode). Minimum recommended copper pour is 25 mm² per side with ≥2 internal thermal vias to inner ground planes for sustained 200 mA operation.
