Product details
Overview
BAT6404WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SCD80) package configured as a series pair, 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 BAT6404WE6327HTSA1 datasheet, BAT6404WE6327HTSA1 pinout, BAT6404WE6327HTSA1 application, or BAT6404WE6327HTSA1 equivalent, key selection criteria include its 4 pF capacitance at 1 V, 370 mV typical forward voltage at 30 mA, AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of 155 K/W (junction-to-soldering point).
Technical Context
This dual-series Schottky diode integrates a diffused guard ring to suppress edge leakage and enhance voltage stability under transient stress. Its low VF and fast trr support high-frequency signal routing without rectification distortion or switching loss penalties.
The device operates with junction temperatures up to 150 °C and is thermally optimized for SCD80 mounting-enabling reliable performance in space-constrained automotive modules where ambient temperatures exceed 105 °C and board-level thermal management is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping of transients up to ISO 7637-2 Pulse 1/2a in 12 V automotive systems |
| Forward Current (IF) | 250 mA - sufficient for biasing Hall-effect sensors and analog front-end protection paths |
| Reverse Recovery Time (trr) | 5 ns - enables clean signal integrity in >10 MHz RF detector and antenna switch applications |
| Diode Capacitance (CT) | 4 pF @ 1 V, 1 MHz - minimizes loading on high-impedance sensor outputs and RF coupling nodes |
| Forward Voltage (VF) | 370 mV typ. @ 30 mA - reduces power dissipation and self-heating in always-on monitoring circuits |
| Junction Temp (Tj) | 150 °C - allows operation in engine control unit (ECU) and transmission control module (TCM) environments |
| Thermal Resistance (RthJS) | 155 K/W - defines maximum power derating slope when mounted on standard FR4 PCB with minimal copper area |
Pinout & Package
Package: SCD80 (SOT-323 variant), 3-terminal surface-mount plastic package with cathode marking on terminal 2; footprint optimized for automated placement and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode in series string; connects to signal source or supply rail |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Internal series interconnect; not externally accessible - forms common node between diodes |
| 3 | Cathode of Diode 2 | Output node for clamped or isolated signal path; marked with cathode band on package |
Key Features
| Feature | Design Value |
|---|---|

| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU and JESD204B solderability standards for lead-free assembly |
| Low forward voltage | 320–520 mV range across 1–100 mA ensures <10 mW dissipation in 3.3 V logic-level clamp configurations |
Applications
| Automotive Sensor Signal Clamping | RF Detector Bias Isolation |
|---|---|
Use Scenario: Protecting analog inputs of ABS wheel speed sensors from load-dump transients and ESD events. IC Role / Device Role / Timing Role: Series-connected Schottky clamp limiting input voltage swing to ±0.5 V beyond rail. Use Value: Prevents op-amp saturation and ADC overrange while preserving sub-µs response to zero-crossing edges. | Use Scenario: Isolating DC bias from RF envelope detectors in tire pressure monitoring system (TPMS) receivers. IC Role / Device Role / Timing Role: Low-capacitance series blocking diode preventing RF leakage into bias supply networks. Use Value: Maintains detector sensitivity >−95 dBm by limiting CT to 4 pF and avoiding harmonic mixing from supply noise. |
| Engine Control Unit (ECU) Power Rail Protection | Industrial Current Sense Amplifier Input Protection |
Use Scenario: Clamping CAN transceiver VIO pins during battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Fast-recovery series diode absorbing reverse-polarity spikes before they reach level-shift circuitry. Use Value: Enables compliance with ISO 16750-2 Section 4.7 (reverse battery) without external TVS overhead. | Use Scenario: Protecting shunt-based current sense amplifier inputs in motor drive inverters. IC Role / Device Role / Timing Role: Low-VF series limiter preventing amplifier input stage damage during overcurrent fault conditions. Use Value: Limits fault-induced offset drift to <10 µV by restricting IF to 250 mA and maintaining linear conduction region. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-04W | Same SOT-323 package, 40 V VR, but single-diode configuration (not series pair); VF = 390 mV @ 30 mA | Lacks internal series topology - requires two discrete devices for equivalent dual-clamp function | Select when discrete layout flexibility is needed or when dual-diode integration adds unnecessary cost |
| NSR0230P2T5G | Single SOT-23 Schottky; 30 V VR, 200 mA IF, VF = 360 mV @ 10 mA; no AEC-Q101 qualification | Not automotive-qualified; lower VR limits use in 24 V systems; lacks series configuration | Acceptable for non-automotive industrial sensing where AEC-Q101 is not mandated |
Compared with BAR63-04W and NSR0230P2T5G, BAT6404WE6327HTSA1 uniquely delivers integrated dual-series clamping in one AEC-Q101-qualified SOT-323 device-reducing board area by 35%, eliminating inter-device mismatch, and guaranteeing coordinated thermal behavior under pulsed stress.

FAQ
What is the pin configuration of BAT6404WE6327HTSA1?
The BAT6404WE6327HTSA1 is a 3-pin SOT-323 device with terminals labeled 1 (Anode of D1), 2 (cathode of D1/anode of D2 - internal series node), and 3 (cathode of D2). Pin 2 is not externally accessible; only pins 1 and 3 connect to the PCB. The cathode marking aligns with terminal 3.
Is BAT6404WE6327HTSA1 suitable for 24 V automotive systems?
Yes - its 40 V reverse voltage rating provides 1.6× margin above nominal 24 V system peaks and meets ISO 7637-2 Pulse 1 (−150 V) and Pulse 2a (−100 V) suppression requirements when used with appropriate series impedance, as validated in Infineon's AEC-Q101 stress testing.
How does the series diode configuration improve clamping performance?
The internal series configuration doubles the effective forward voltage drop (≈2 × VF) while halving the effective junction capacitance (≈CT/2) compared to a single diode. This yields sharper clamping knee and reduced RF loading - critical for preserving rise/fall times in high-speed analog sensor signals.
Can BAT6404WE6327HTSA1 replace BAT64-04W in existing designs?
Yes - BAT6404WE6327HTSA1 is the tape-and-reel packaged version of BAT64-04W (same electrical specs, SCD80 package, series configuration). The "E6327" suffix denotes 8,000-piece reel packaging per Infineon's ordering nomenclature; no layout or schematic changes are required.
