Product details
Overview
BAT5404WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SC-70) package, configured as a single discrete device with 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, and 10 pF capacitance at 1 V - used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5404WH6327XTSA1 datasheet, BAT5404WH6327XTSA1 pinout, BAT5404WH6327XTSA1 application, or BAT5404WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low VF (400 mV @ 10 mA), guard ring protection, and thermal resistance of ≤117 °C/W (junction-to-soldering point).
Technical Context
This Schottky diode employs a planar silicon structure with guard ring passivation to suppress edge breakdown and ensure stable reverse leakage (<2 µA @ 25 V). Its low forward voltage drop and fast recovery (trr ≤ 5 ns) stem from minimal minority carrier storage and optimized metal-semiconductor junction design.
Thermal performance is defined by junction-to-soldering-point resistance (RthJS ≤ 117 K/W), enabling reliable operation up to 150 °C junction temperature when mounted on standard epoxy PCBs with 6 cm² copper area - critical for under-hood automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports clamping in 24 V automotive supply rails without breakdown |
| Forward Current (IF) | 200 mA continuous - sufficient for biasing and signal-level protection in sensor interfaces |
| Reverse Recovery Time (trr) | 5 ns - enables high-speed switching in ESD transient suppression and signal routing |
| Forward Voltage (VF) | 400 mV @ 10 mA - reduces conduction loss and self-heating in low-power analog paths |
| Diode Capacitance (CT) | 10 pF @ 1 V, 1 MHz - minimizes signal distortion in RF-adjacent sensor front-ends |
| Junction Temperature (Tj) | 150 °C - meets extended thermal requirements for engine control and transmission modules |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package, 3-pin configuration with anode, cathode, and exposed thermal pad (pin 3 not electrically connected but thermally tied to cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main current entry point; connects to positive rail or signal source in clamp/bias applications |
| 2 | Cathode | Main current exit; ties to ground or reference node; electrically bonded to thermal pad (pin 3) |
| 3 | Thermal Pad | Non-electrical thermal sink; improves power dissipation and long-term reliability under thermal cycling |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protected junction | Prevents premature edge breakdown under high dv/dt, ensuring stable VR rating across temperature |
| Pb-free (RoHS compliant) construction | Meets EU Directive 2011/65/EU and automotive ELV requirements without lead-based solder compatibility issues |
| Low forward voltage (VF) | Typical 400 mV @ 10 mA - cuts conduction loss by >50% vs. standard silicon PN diodes in same package |
| AEC-Q101 qualified | Validated per stress test conditions including HTGB, TCT, and H3TRB - required for safety-critical ECUs |
| Fast reverse recovery (trr) | ≤5 ns - eliminates switching tail current in high-frequency clamp circuits, reducing EMI generation |
Applications
| Automotive Sensor Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Clamp transient overvoltage on LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control units. IC Role / Device Role / Timing Role: Discrete Schottky clamp diode placed between signal line and battery ground to shunt transients below 30 V. Use Value: Prevents damage to downstream ADC inputs with <2 µA leakage at 25 V and 5 ns response to fast spikes. | Use Scenario: Protect USB 2.0 D+/D− lines from IEC 61000-4-2 contact discharge events in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance (10 pF) bidirectional clamp limiting line voltage to ±30 V during ESD events. Use Value: Maintains signal integrity up to 480 Mbps while meeting automotive ESD immunity targets (±15 kV air, ±8 kV contact). |
| Power Rail Bias Isolation | Low-Power Signal Rectification |
Use Scenario: Isolate auxiliary 5 V bias rail from main 12 V supply in ADAS camera modules to prevent backfeed during sleep mode. IC Role / Device Role / Timing Role: Single Schottky diode in series with bias path to block reverse current while minimizing dropout. Use Value: Achieves <400 mV forward drop at 100 mA, preserving >92% of available bias voltage for image sensor LDOs. | Use Scenario: Full-wave rectification of low-amplitude AC signals (e.g., piezoelectric knock sensor output) in engine management systems. IC Role / Device Role / Timing Role: Discrete Schottky pair (BAT5404W variant) used in precision half-wave rectifier stage before op-amp amplification. Use Value: Enables accurate peak detection down to 10 mV input due to sub-500 mV VF and negligible stored charge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW1T3G | Same SOT-323 package, 30 V VR, but VF = 450 mV @ 10 mA; trr = 6 ns; not AEC-Q101 qualified | Not approved for automotive safety-critical modules; suitable for industrial/commercial USB or sensor interfaces | Select only if AEC-Q101 is not required and 50 mV higher VF is acceptable in thermal budget |
| BAT54C,215 | Common-cathode dual configuration in SOT-23; VR = 30 V, VF = 370 mV @ 10 mA; trr = 5 ns; AEC-Q101 qualified | Requires layout change (dual-channel vs. single); better for paired signal paths (e.g., RS-485 differential lines) | Choose when dual-diode topology matches system architecture and board space allows SOT-23 footprint |
Compared with SBAT54DW1T3G and BAT54C,215, BAT5404WH6327XTSA1 uniquely combines AEC-Q101 qualification, 400 mV VF, and single-diode SOT-323 packaging - making it optimal for space-constrained, thermally demanding automotive sensor nodes where reliability and low loss are jointly critical.

FAQ
Is BAT5404WH6327XTSA1 pin-compatible with BAT54W?
No - BAT5404WH6327XTSA1 uses SOT-323 (3-pin) packaging with anode/cathode/thermal pad, while BAT54W uses SOT-323 but is a single-diode variant without thermal pad connection. Pin 3 on BAT5404WH6327XTSA1 is a dedicated thermal pad, not electrically functional, whereas BAT54W pin 3 is unconnected. Layout redesign is required for substitution.
What is the maximum allowable PCB copper area for thermal derating?
The datasheet specifies thermal resistance (RthJS ≤ 117 K/W) measured on a 40 × 40 × 1.5 mm epoxy PCB with 6 cm² of 1 oz copper. Increasing copper area beyond 6 cm² yields diminishing returns; no tested data exists for >12 cm². For designs exceeding 150 mW dissipation, use internal layer copper pours and thermal vias to the backside ground plane.
Does BAT5404WH6327XTSA1 support reflow soldering per J-STD-020?
Yes - it is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 sec above 217 °C) per J-STD-020D. The SOT-323 package withstands thermal shock due to its low mass and optimized mold compound; no special pre-bake is required unless stored >12 months in non-dry-pack conditions.
How does guard ring protection improve reliability in automotive environments?
The integrated guard ring prevents high-field concentration at the diode junction periphery, suppressing early avalanche onset during load dump or ISO 7637-2 pulse 5a transients. This extends operational life under repeated thermal cycling and ensures consistent 30 V VR rating across −40 °C to +150 °C ambient, verified per AEC-Q101 stress tests.
