Product details
Overview
BAT6406E6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common anode dual diode in SCD80 (SOT-23 variant) package, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time. It delivers low forward voltage (370 mV typ. at 30 mA), 4 pF capacitance at 1 V, and is qualified to AEC-Q101 for automotive meter protection and bias isolation.
For engineers reviewing the BAT6406E6327HTSA1 datasheet, BAT6406E6327HTSA1 pinout, BAT6406E6327HTSA1 application, or BAT6406E6327HTSA1 equivalent, key selection criteria include its common-anode dual configuration, 40 V VR rating, sub-500 mV VF at 100 mA, thermal resistance of ≤155 K/W (junction-to-soldering point), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This dual Schottky diode integrates a diffused guard ring for robust ESD tolerance and stable breakdown behavior. Its common-anode topology enables compact dual-path clamping or polarity-selective biasing in space-constrained PCB layouts.
The device operates with junction temperatures up to 150 °C and supports pulsed forward currents exceeding 800 mA for short durations (t ≤ 10 ms), while maintaining low leakage (<2 µA at 30 V, 25 °C) and fast switching (trr ≤ 5 ns under specified IF/IR conditions).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability before breakdown; suitable for 24 V automotive supply rail clamping. |
| Forward Current (IF) | 250 mA continuous - Supports sustained bias or signal path current in sensor interface and metering circuits. |
| Forward Voltage (VF) | 370 mV typ. @ 30 mA - Minimizes conduction loss and self-heating in low-voltage analog front-ends. |
| Reverse Recovery Time (trr) | 5 ns max - Enables reliable operation in >10 MHz signal clamping and RF detector applications. |
| Diode Capacitance (CT) | 4 pF @ 1 V, 1 MHz - Low junction capacitance preserves high-frequency signal integrity in RF sampling paths. |
| Junction Temp (Tj) | 150 °C - Allows deployment in engine control units and other high-ambient-temperature automotive zones. |
| Thermal Resistance (RthJS) | ≤155 K/W - Enables efficient heat transfer from die to solder joint on standard FR-4 PCBs with minimal copper area. |
Pinout & Package
Package: SCD80 - A miniature surface-mount variant of SOT-23 with gull-wing leads, optimized for automated assembly and high-density routing. Dimensions: 1.7 mm × 0.8 mm × 0.7 mm (L × W × H); cathode marked by laser on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first Schottky path; connects to signal source or supply rail requiring clamping. |
| Pin 2 | Cathode (Common) | Shared output node for both diodes; ties to reference potential (e.g., ground or bias rail). |
| Pin 3 | Anode of Diode 2 | Input node for second independent Schottky path; enables dual-rail or differential clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables compact dual-channel clamping or bidirectional signal steering without external node sharing. |
| Integrated diffused guard ring | Improves voltage standoff consistency and reduces parameter drift under temperature cycling and ESD stress. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock. |
| Pb-free (RoHS-compliant) packaging | Meets global environmental compliance requirements without compromising thermal or electrical performance. |
Applications
| Automotive Instrument Cluster Protection | RF Signal Detector Clamping |
|---|---|
Use Scenario: Protecting analog inputs of digital instrument cluster microcontrollers from transients induced by ignition noise or load dump. IC Role / Device Role: Dual Schottky clamp limiting input voltage to ±0.5 V beyond rail, leveraging common-cathode structure for bidirectional suppression. Use Value: Prevents ADC saturation and latch-up while adding <0.5 mm² PCB area due to SCD80 footprint and integrated dual topology. | Use Scenario: Peak detection and envelope extraction in UHF RFID reader front-ends operating at 860–960 MHz. IC Role / Device Role: Low-CT, fast trr Schottky diode rectifying RF bursts with minimal distortion and phase shift. Use Value: Achieves >40 dB dynamic range with <1.5 dB insertion loss thanks to 4 pF CT and 5 ns trr. |
| Low-Voltage Sensor Bias Isolation | Industrial Metering Input Protection |
Use Scenario: Isolating precision voltage references from leakage-sensitive sensor bridges (e.g., strain gauges) in battery-powered IoT nodes. IC Role / Device Role: Low-IR (<2 µA @ 30 V) Schottky barrier preventing reference rail contamination during standby. Use Value: Maintains <0.01% reference accuracy over -40 to +125 °C, enabled by low leakage and stable VF tracking. | Use Scenario: Protecting energy meter ASIC inputs from surges on AC mains-connected current/voltage sensing lines. IC Role / Device Role: Fast-recovery, low-VF clamp absorbing 800 mA non-repetitive surges per IEC 61000-4-5 Level 3. Use Value: Survives 10 kV surge events without degradation, validated per AEC-Q101 stress profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Single Schottky in SCD80; 30 V VR, 200 mA IF, 3 ns trr, 0.6 nH LS | Lacks dual-diode topology; requires two devices for common-anode function | Select when only one clamping path is needed and ultra-fast trr is prioritized over dual integration. |
| NSR0230HT1G | Single Schottky in SOD-523; 30 V VR, 200 mA IF, 4 ns trr, 300 mV VF @ 10 mA | Smaller footprint but no dual configuration; higher RthJA (~300 K/W) | Prefer for ultra-miniature designs where board space is critical and thermal margin allows single-device use. |
Compared with BAR63-02W and NSR0230HT1G, BAT6406E6327HTSA1 uniquely provides dual common-anode Schottky functionality in a single SCD80 package with AEC-Q101 qualification-enabling space-efficient, automotive-grade dual-path protection without layout duplication or thermal derating penalties.

FAQ
What is the marking code for BAT6406E6327HTSA1?
The top-side laser marking for BAT6406E6327HTSA1 is "66s", consistent with Infineon's BAT64-06W family identification. This marking appears adjacent to the cathode band on the SCD80 package and is verified per Infineon's 2007 datasheet revision.
Is BAT6406E6327HTSA1 suitable for 125 °C ambient operation?
Yes - the device supports junction temperatures up to 150 °C and is rated for continuous operation at 125 °C ambient when mounted on standard FR-4 with recommended pad layout. Derating curves in the datasheet confirm 250 mA IF remains valid at TS = 111 °C for the BAT64-06W variant.
Does BAT6406E6327HTSA1 have integrated ESD protection?
No - it is an ESD-sensitive device (Class 1B per JEDEC JS-001), requiring handling per ANSI/ESD S20.20. While the diffused guard ring improves ruggedness, no on-chip TVS or snapback circuitry is integrated; external ESD protection must be added per system-level requirements.
Can BAT6406E6327HTSA1 replace BAT64-06 in existing designs?
Yes - BAT6406E6327HTSA1 is the tape-and-reel packaged version of BAT64-06W (SCD80, common anode), with identical electrical specs, thermal ratings, and pinout. The "E6327" suffix denotes 3,000-piece reel packaging; "HTSA1" indicates RoHS-compliant lead finish and standard quality grade.
