Product details
Overview
BAT 54-04W E6327 from Infineon Technologies is a silicon Schottky diode in SOT-323 package configured as a single discrete device, with 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, 10 pF capacitance at 1 V, and 117 °C max junction temperature-used for low-loss clamping and bias isolation in portable power management circuits.
For engineers reviewing the BAT 54-04W E6327 datasheet, BAT 54-04W E6327 pinout, BAT 54-04W E6327 application, or BAT 54-04W E6327 equivalent, key selection criteria include its low VF (400 mV @ 10 mA), AEC-Q101 qualification, thermal resistance of 145 K/W (junction-to-soldering point), and SOT-323 footprint compatibility with space-constrained DC-DC feedback paths and USB port protection.
Technical Context
This Schottky diode operates with metal–semiconductor junction physics to achieve fast switching and low forward conduction loss. Its guard ring structure enhances ruggedness against surface leakage and transient overstress, while the Pb-free RoHS-compliant SOT-323 package supports reflow assembly and meets automotive reliability requirements per AEC-Q101.
The device exhibits minimal reverse recovery charge (Qrr < 1 nC implied by trr = 5 ns) and stable VF over temperature (0.4 V @ 10 mA, –40°C to +125°C), making it suitable for high-frequency flyback snubbing and precision analog signal clamping where parasitic inductance and thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports 24 V rail clamping and 5 V logic-level protection without breakdown |
| Forward Current (IF) | 200 mA continuous - sufficient for bias supply isolation in low-power sensor interfaces |
| Reverse Recovery Time (trr) | 5 ns - enables operation up to ~35 MHz switching frequencies in snubber networks |
| Diode Capacitance (CT) | 10 pF @ 1 V, 1 MHz - minimizes signal distortion in RF detector and high-speed data line clamping |
| Forward Voltage (VF) | 400 mV @ 10 mA - reduces conduction loss by >60% vs. standard PN diodes in battery-fed circuits |
| Junction Temperature (Tj) | 150 °C - allows sustained operation in sealed industrial enclosures with limited airflow |
| Thermal Resistance (RthJS) | 145 K/W - defines solder-point temperature rise under 200 mA load for PCB thermal design |
Pinout & Package
SOT-323 (SC-70) 3-pin plastic package with gull-wing leads; compact 2.1 × 1.25 × 0.95 mm outline optimized for automated placement and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal | Connected to higher-potential node during forward conduction; requires trace width ≥ 0.25 mm for 200 mA |
| Cathode (Pin 2) | Current exit terminal | Internally tied to substrate pad; serves as primary heat path to PCB copper pour |
| NC / Substrate (Pin 3) | Non-connected internal die attach pad | Electrically isolated; may be grounded for EMI reduction but not required for function |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown under high dv/dt, improving long-term reliability in surge-prone inputs |
| AEC-Q101 qualified | Validated for automotive electronics including infotainment power rails and body control modules |
| Low VF temperature stability | Drift < 0.2 mV/°C from –40°C to +125°C - maintains consistent clamping threshold across ambient range |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C) |
Applications
| USB Port ESD Protection | DC-DC Feedback Path Clamp |
|---|---|
Use Scenario: Clamps transient voltages on USB D+/D− lines during hot-plug events and ESD strikes. IC Role / Device Role: Low-capacitance shunt diode providing bidirectional clamping to VBUS and GND. Use Value: 10 pF CT ensures < 0.5 dB insertion loss at 480 MHz; 5 ns trr prevents latch-up during fast transients. | Use Scenario: Limits feedback node voltage swing in isolated flyback converters to protect optocoupler input. IC Role / Device Role: Fast-recovery clamp limiting error amplifier output excursion during overload. Use Value: 400 mV VF avoids false regulation tripping; 145 K/W RthJS sustains 200 mA peak without thermal shutdown. |
| Automotive Sensor Bias Isolation | Portable Device Battery Monitoring |
Use Scenario: Isolates 5 V bias from microcontroller ADC reference in engine control units. IC Role / Device Role: Reverse-biased Schottky blocking diode preventing backfeed into sensor supply rail. Use Value: 2 µA IR @ 25 V ensures < 1 µA leakage at 125°C - preserves sensor accuracy over full AEC-Q101 temp range. | Use Scenario: Protects fuel gauge IC from reverse polarity during battery swap in handheld medical devices. IC Role / Device Role: Series protection diode in main battery path with minimal forward drop. Use Value: 400 mV VF at 100 mA adds < 1% error to battery voltage reading; SOT-323 fits 3.5 mm² board area budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F (Diodes Inc.) | Same SOT-323 package, 30 V VR, but VF = 450 mV @ 10 mA; trr = 6 ns; RthJS = 150 K/W | Marginally higher conduction loss; slightly reduced thermal margin in sealed enclosures | Preferred when dual-diode configuration (common cathode) is needed for differential clamping |
| BAT54C-7-F (Diodes Inc.) | Common-cathode dual Schottky in SOT-23; VR = 30 V, VF = 420 mV @ 10 mA, trr = 5 ns | Requires SOT-23 footprint; occupies 30% more board area than SOT-323 | Selected when dual-channel clamping (e.g., RS-485 bus) is required and layout allows larger package |
Compared with SBAT54DW-7-F and BAT54C-7-F, BAT 54-04W E6327 offers the lowest thermal resistance (145 K/W) and smallest footprint (SOT-323), making it optimal for thermally constrained, single-diode applications like USB port protection and feedback clamping where board space and thermal headroom are critical.

FAQ
Is BAT 54-04W E6327 pin-compatible with BAT54-04?
No. BAT 54-04W E6327 uses SOT-323 packaging, while BAT54-04 is in SOT-23. Pin numbering differs: SOT-323 has Anode (Pin 1), Cathode (Pin 2), NC (Pin 3); SOT-23 has Anode (Pin 1), Cathode (Pin 2), Cathode (Pin 3) for common-cathode variants. Footprint and soldering profile are not interchangeable.
What is the maximum allowable PCB copper area for thermal performance?
For rated 200 mA continuous operation, a minimum 6 cm² copper pour (40 × 40 × 1.5 mm epoxy PCB) is specified per Infineon's thermal test condition. Reducing copper area below this increases junction temperature linearly - e.g., 2 cm² raises RthJA by ~40%, limiting safe IF to ~120 mA at TA = 70°C.
Does BAT 54-04W E6327 support reflow soldering per JEDEC J-STD-020?
Yes. As a Pb-free RoHS-compliant device, it is qualified for standard lead-free reflow with peak temperature ≤ 260°C (10-second duration), ramp rate ≤ 3°C/s, and preheat soak at 150–200°C for 60–120 seconds - matching JEDEC J-STD-020D Level 1 requirements for SOT-323 packages.
How does guard ring protection improve reliability in automotive use?
The integrated guard ring suppresses surface leakage currents and prevents premature avalanche at the diode edge under high electric field stress. In automotive environments, this extends lifetime under repeated load-dump transients (ISO 7637-2 Pulse 5a) and improves immunity to humidity-induced parametric shift, validated per AEC-Q101 stress tests including HTRB and TCT.
