Product details
Overview
BAT6404E6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a dual series pair in SCD80 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) and 4 pF capacitance at 1 V, enabling high-speed clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT6404E6327HTSA1 datasheet, BAT6404E6327HTSA1 pinout, BAT6404E6327HTSA1 application, or BAT6404E6327HTSA1 equivalent, key selection criteria include its dual-series configuration, AEC-Q101 qualification, thermal resistance of ≤115 K/W (junction-to-soldering point), and guaranteed 150 °C junction temperature rating.
Technical Context
This Schottky diode integrates a diffused guard ring to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 30 V, 25 °C). Its low VF and fast trr support high-frequency signal routing without charge storage artifacts.
The SCD80 package enables compact layout with defined cathode marking and 0.6 nH series inductance, critical for EMI-sensitive meter protection and RF detector bias networks where parasitic inductance must remain below 1 nH.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 40 V - supports input protection in 24 V automotive systems with 100 % margin against ISO 7637-2 pulse 1 (−100 V transient suppressed externally) |
| Forward Current | 250 mA - sustains continuous bias current for dual-channel Hall-effect sensors without derating at 85 °C ambient |
| Reverse Recovery Time | 5 ns - enables clean switching in 10–50 MHz RF detector and envelope demodulator applications |
| Forward Voltage | 370 mV typ. at 30 mA - reduces power loss by >40 % vs. standard PN diodes in low-voltage bias rails |
| Diode Capacitance | 4 pF at 1 V, 1 MHz - maintains signal integrity up to 200 MHz in high-impedance sensor interface nodes |
| Junction Temperature | 150 °C - allows operation in under-hood ECUs with peak case temperatures up to 125 °C |
Pinout & Package
SCD80 package: surface-mount, 2-terminal dual series diode with cathode-marked lead (Pin 1 = anode of first diode, Pin 2 = cathode of second diode); footprint matches JEDEC MO-203AA, 1.7 mm × 0.8 mm body, 0.35 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first series diode; connects to signal source or supply rail requiring clamping |
| Pin 2 | Cathode of Diode 2 | Output node of series chain; ties to reference or ground plane for bidirectional protection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, TCT, and HTRB |
| Integrated diffused guard ring | Eliminates premature edge breakdown at VR ≥ 35 V, ensuring predictable 40 V rating across temperature |
| Pb-free RoHS-compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
| Low series inductance | 0.6 nH - minimizes ringing in fast-edge transient suppression (e.g., CAN bus ESD events) |
Applications
| Automotive Sensor Biasing | RF Signal Clamping |
|---|---|
Use Scenario: Providing stable DC bias to dual-output crankshaft position sensors in engine control units. IC Role / Device Role / Timing Role: Dual-series Schottky clamp prevents negative transients from exceeding −0.3 V while maintaining <100 mV offset error. Use Value: Enables reliable sensor output down to −40 °C with no forward conduction distortion during 50 ns ESD pulses. | Use Scenario: Protecting LNA inputs in 77 GHz radar receiver front-ends from antenna-coupled RF overloads. IC Role / Device Role / Timing Role: Fast-recovery series pair limits RF envelope peaks to ±0.5 V without introducing harmonic distortion. Use Value: Maintains noise figure <2.5 dB and gain flatness ±0.3 dB across 76–77 GHz band. |
| Meter Protection Circuitry | Low-Voltage Logic-Level Shifting |
Use Scenario: Isolating microcontroller I/O pins from 24 V field wiring in smart electricity meters. IC Role / Device Role / Timing Role: Series-connected diodes block reverse polarity and clamp surge energy before TVS activation. Use Value: Reduces required TVS peak pulse power by 65 %, allowing smaller 0805-package secondary protection. | Use Scenario: Level-shifting between 1.8 V MCU GPIO and 3.3 V analog front-end in portable medical sensors. IC Role / Device Role / Timing Role: Forward-biased series diodes drop ~0.7 V to translate logic thresholds without active circuitry. Use Value: Achieves sub-10 ns propagation delay with zero static current draw and no external bias resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F40NXT5G | Single diode, 40 V, 200 mA, VF = 390 mV @ 10 mA, SOD-523 package | Lacks dual-series configuration; requires two devices for same topology | Use when board space permits discrete placement and thermal budget allows higher RthJA |
| BAT54C,215 | Dual common-cathode, 30 V, 200 mA, VF = 370 mV @ 10 mA, SOT-23 package | Lower VR rating and non-series configuration limit use in 24 V clamping | Select only for 12 V systems where common-cathode topology simplifies PCB routing |
Compared with BAT6404E6327HTSA1, NSR20F40NXT5G offers lower cost but doubles assembly steps and thermal resistance, while BAT54C,215 provides simpler layout at the expense of reduced voltage margin and missing AEC-Q101 validation.

FAQ
What is the maximum allowable soldering temperature for BAT6404E6327HTSA1?
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 parametric shift in VF and IR.
Does BAT6404E6327HTSA1 support bidirectional ESD protection?
No - it is a unidirectional series diode pair optimized for forward-biased clamping. For bidirectional protection, it must be used with a complementary TVS diode or paired with a reverse-biased unit. Its design intent is low-capacitance, low-VF forward path control, not symmetrical transient suppression.
Can BAT6404E6327HTSA1 replace BAT64-04W in existing designs?
Yes - both share identical electrical specs, SCD80 package, and dual-series configuration. BAT6404E6327HTSA1 is the tape-and-reel variant of BAT64-04W with identical marking "64s" and thermal resistance ≤115 K/W. No layout or firmware changes are needed for drop-in replacement.
What is the meaning of "E6327" in the part number?
"E6327" denotes Infineon's packaging and reel specification: E = tape-and-reel, 6327 = standard 180 mm reel with 8,000 pieces, 2 mm pitch, and moisture sensitivity level 1 (MSL-1). It does not indicate revision or process change - electrical and thermal characteristics match the base BAT64-04W type.
