Product details
Overview
BAT54WH6327XTSA1 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 capability, 5 ns reverse recovery time, and 400 mV forward voltage at 10 mA - used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT54WH6327XTSA1 datasheet, BAT54WH6327XTSA1 pinout, BAT54WH6327XTSA1 application, or BAT54WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low VF at low IF, guard ring protection, and thermal performance under TS ≤ 117 °C in automotive ambient conditions.
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 at 25 V). Its low junction capacitance (10 pF at 1 V) and fast trr (5 ns) support high-frequency clamping in analog front-end protection paths.
The device operates with a maximum junction temperature of 150 °C and exhibits thermal resistance RthJS ≤ 145 K/W (junction-to-soldering point), enabling reliable operation in compact automotive PCB layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports rail-to-rail signal clamping in 24 V automotive systems without breakdown. |
| Forward Voltage (VF) | 400 mV at 10 mA - minimizes conduction loss in low-power bias networks and precision reference paths. |
| Reverse Recovery Time (trr) | 5 ns - enables effective high-speed transient suppression in ADC input protection and CAN bus interface circuits. |
| Reverse Leakage (IR) | ≤2 µA at 25 V - ensures negligible error current in high-impedance sensor biasing and voltage divider networks. |
| Junction Capacitance (CT) | 10 pF at 1 V, 1 MHz - preserves signal integrity in RF-adjacent analog signal chains and low-noise amplifier inputs. |
| Thermal Resistance (RthJS) | ≤145 K/W - allows sustained 200 mA operation with <30 °C junction rise above solder point on standard FR4. |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package, 3-pin configuration with cathode-anode-cathode pin assignment (pin 1 = anode, pin 2 = cathode, pin 3 = NC/not connected - confirmed per Infineon BAT54W series pinout diagram).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction path; connects to protected node or bias source. |
| Pin 2 | Cathode | Output/return terminal; ties to ground or lower-potential rail for clamping action. |
| Pin 3 | No Connection | Internally isolated; must remain unconnected to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under high dv/dt, ensuring consistent VR rating across temperature and process variation. |
| Pb-free RoHS-compliant packaging | Enables direct compatibility with lead-free reflow profiles (peak 260 °C) and meets EU Directive 2011/65/EU. |
| Low forward voltage at microamp bias | 240 mV at 0.1 mA - critical for ultra-low-power wake-up circuits and battery-backed sensor nodes. |
| Fast switching with minimal stored charge | 5 ns trr and negligible Qrr - eliminates switching tail current in sample-and-hold and multiplexer protection stages. |
Applications
| Automotive Sensor Signal Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Protecting analog outputs of pressure and temperature sensors in engine control modules from load dump transients. IC Role / Device Role / Timing Role: Low-VF Schottky clamp diode placed between sensor output and 5 V rail to shunt overvoltage spikes. Use Value: Prevents ADC saturation and latch-up with <5 ns response and <2 µA leakage at 25 V, preserving measurement accuracy. |
Use Scenario: Bidirectional ESD protection for USB 2.0 D+ and D− lines in infotainment head units. IC Role / Device Role / Timing Role: Discrete low-capacitance clamp limiting line voltage to ±5.5 V during IEC 61000-4-2 contact discharge events. Use Value: 10 pF CT avoids signal integrity degradation at 480 Mbps while maintaining 30 V standoff for system-level surge immunity. |
| Low-Power Bias Isolation | RF Detector Circuit Protection |
Use Scenario: Isolating bias current from LDO regulators feeding RF power amplifier bias networks. IC Role / Device Role / Timing Role: Series-connected Schottky blocking diode preventing reverse current flow during sleep mode. Use Value: 400 mV VF at 10 mA reduces quiescent power loss by >60% vs. standard PN diodes, extending battery life in telematics modules. |
Use Scenario: Protecting logarithmic detector IC inputs in cellular baseband receivers from antenna coupling surges. IC Role / Device Role / Timing Role: Clamp diode placed before detector input to limit RF envelope peaks to safe DC levels. Use Value: Guard ring design ensures stable 30 V VR under RF-modulated stress, avoiding parametric shift in dBm-to-volt conversion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Lower VF (310 mV @ 10 mA), higher IR (5 µA @ 25 V), same SOT-323 package. | Higher leakage limits use in high-impedance reference dividers; better for ultra-low-VF bias paths. | Select when forward loss dominates design margin, and leakage can be tolerated. |
| BAT54CW,115 | Common-cathode dual configuration, identical VF/trr/RthJS, but requires two diodes per function. | Not suitable for single-diode clamping; only applicable where dual-channel layout or shared cathode simplifies routing. | Choose only if board space permits dual-device placement and shared cathode improves layout symmetry. |
Compared with NSR0230HT1G and BAT54CW,115, BAT54WH6327XTSA1 offers the best balance of low leakage, AEC-Q101 qualification, and proven thermal robustness in single-diode automotive signal-path roles - making it preferred for safety-critical sensor interfaces.

FAQ
Is BAT54WH6327XTSA1 pin-compatible with BAT54W?
Yes - BAT54WH6327XTSA1 uses the same SOT-323 package and pin 1 (anode)/pin 2 (cathode)/pin 3 (NC) assignment as all BAT54W-series variants. No PCB redesign is required for substitution within the same functional configuration.
What is the maximum continuous forward current at 125°C ambient?
At TA = 125°C, the maximum continuous forward current is derated to approximately 120 mA based on the IF vs. TS curve for BAT54W in the datasheet, with thermal resistance limiting junction temperature to 150°C under typical PCB copper conditions.
Does this part support reflow soldering with lead-free processes?
Yes - BAT54WH6327XTSA1 is qualified for lead-free reflow per JEDEC J-STD-020, with a peak temperature rating of 260°C and MSL level 1, enabling standard Pb-free assembly without pre-baking or special handling.
How does guard ring protection improve reliability in automotive applications?
The integrated guard ring suppresses electric field crowding at the die edge, preventing early avalanche onset during load dump or jump-start transients - thereby maintaining specified 30 V VR rating across full temperature range and lifetime stress conditions.
