Product details
Overview
BAT5405WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SC-70) package, configured as a single anode-cathode junction with 30 V reverse voltage rating, 200 mA forward current capability, and ultrafast 5 ns reverse recovery time. It delivers low forward voltage drop (400 mV at 10 mA), <10 pF capacitance at 1 V, and AEC-Q101 qualification for automotive bias isolation and clamping circuits.
For engineers reviewing the BAT5405WH6327XTSA1 datasheet, BAT5405WH6327XTSA1 pinout, BAT5405WH6327XTSA1 application, or BAT5405WH6327XTSA1 equivalent, this part supports high-speed signal clamping in automotive infotainment power rails, low-loss DC bias networks in sensor interfaces, and ESD-sensitive analog front-ends where thermal robustness and fast switching are critical.
Technical Context
This Schottky diode uses a guard-ring protected silicon junction to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 25 V). Its low series inductance (1.4 nH) and optimized metallization support clean transient response in high-frequency clamp paths.
The device operates across −65 °C to +150 °C junction temperature range with 110 K/W junction-to-soldering-point thermal resistance, enabling reliable performance in thermally constrained automotive PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Supports clamping in 24 V automotive systems with 25 % margin against transients. |
| Forward Current (IF) | 200 mA continuous - Sufficient for bias current in op-amp input protection and level-shifting networks. |
| Forward Voltage (VF) | 400 mV at 10 mA - Minimizes power loss and self-heating in always-on sensor bias paths. |
| Reverse Recovery Time (trr) | 5 ns - Enables use in >10 MHz signal clamping without distortion or ringing. |
| Diode Capacitance (CT) | 10 pF at 1 V, 1 MHz - Preserves bandwidth in RF detector and high-speed logic interface applications. |
| Thermal Resistance (RthJS) | 110 K/W - Allows 150 °C junction operation with ≤48 °C board temperature rise under full load. |
| Leakage Current (IR) | 2 µA max at 25 V - Ensures minimal error current in precision reference and feedback divider networks. |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package, 3-pin configuration with pin 1 = anode, pin 2 = cathode, pin 3 = unused (internal die pad not connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to higher-potential node in clamping or isolation path. |
| Pin 2 | Cathode | Output/return terminal; ties to reference rail (e.g., VCC or GND) in active clamp configurations. |
| Pin 3 | Not connected | No internal bond wire; must remain floating or grounded per layout best practices to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements including HTOL and TC. |
| Guard ring protection | Eliminates premature edge breakdown under high dv/dt, improving long-term reliability in noisy environments. |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles up to 260 °C peak. |
| Low VF temperature coefficient | VF drift <0.2 mV/°C over −40 °C to +125 °C - maintains stable clamping threshold across operating range. |
Applications
| Automotive Sensor Biasing | USB Port ESD Clamping |
|---|---|
Use Scenario: Providing stable DC bias to Hall-effect and thermistor sensors in engine control modules. IC Role / Device Role / Timing Role: Low-loss forward path isolator that prevents reverse current flow while minimizing voltage drop on supply lines. Use Value: 400 mV VF at 10 mA ensures ≥98 % of nominal 5 V bias reaches sensor, preserving measurement accuracy. |
Use Scenario: Protecting USB 2.0 data lines (D+/D−) from ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Fast-turn-on clamping diode shunting transient energy to ground before IC input structures fail. Use Value: 5 ns trr and 10 pF CT enable sub-nanosecond response without signal integrity degradation at 480 Mbps. |
| Industrial Analog Front-End Protection | DC-DC Converter Feedback Isolation |
Use Scenario: Guarding ADC inputs and op-amp rails in programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Bidirectional clamp (anode-to-rail, cathode-to-ground) limiting overvoltage to safe levels during surge events. Use Value: 2 µA IR at 25 V prevents measurable offset error in 12-bit+ measurement chains with MΩ-scale input impedance. |
Use Scenario: Isolating feedback resistors in isolated flyback converters to prevent regulation loop corruption during primary-side transients. IC Role / Device Role / Timing Role: Reverse-biased blocking element preventing current backfeed from optocoupler side into resistor divider. Use Value: 30 V VR rating exceeds typical 24 V auxiliary supplies, ensuring no conduction during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DWHT1G | Same SOT-323 package, dual common-cathode configuration; VF = 420 mV @ 10 mA; trr = 6 ns. | Requires redesign for single-diode footprint; suited for dual-rail clamping (e.g., RS-485 bus). | Select when dual-channel protection is needed and board space permits shared cathode routing. |
| BAT54C,215 | SOT-23 package, common-cathode dual; VF = 370 mV @ 10 mA; trr = 5 ns; RthJS = 245 K/W. | Larger thermal resistance limits continuous current in compact layouts; not AEC-Q101 qualified. | Acceptable for non-automotive industrial use where cost is prioritized over thermal performance and qualification. |
Compared with SBAT54DWHT1G and BAT54C,215, BAT5405WH6327XTSA1 offers superior thermal resistance (110 K/W), guaranteed AEC-Q101 compliance, and exact single-diode SOT-323 fit-making it optimal for space-constrained, safety-critical automotive clamping.

FAQ
Is BAT5405WH6327XTSA1 pin-compatible with BAT54W?
No. BAT5405WH6327XTSA1 uses SOT-323 (3-pin) packaging with pins 1–2 active, while BAT54W uses SOT-323 but is a single-diode variant with identical pinout. However, BAT54W has higher RthJS (125 K/W) and lower IF rating (150 mA), making direct substitution thermally risky at full load.
What is the maximum allowable soldering temperature profile?
The device complies with IPC/JEDEC J-STD-020D for lead-free reflow: peak temperature 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat (150–200 °C) must last 60–120 seconds to avoid moisture-induced delamination.
Does BAT5405WH6327XTSA1 support bidirectional ESD protection?
No. As a single-junction Schottky diode, it conducts only in forward direction. For bidirectional protection, two devices must be placed in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated TVS array like ESD5Z5.0T1G should be used.
How does its 110 K/W RthJS compare to standard SOT-23 diodes?
Standard SOT-23 Schottky diodes (e.g., BAT54) exhibit RthJS ≈ 245 K/W due to larger die attach area and less efficient thermal path. BAT5405WH6327XTSA1's 110 K/W reflects optimized die pad design and thinner mold compound, enabling 2.2× higher power dissipation at equal board temperature rise.
