Product details
Overview
BAT5404E6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-23 package configured as a single discrete device with 30 V reverse voltage rating, 200 mA forward current capability, and 5 ns reverse recovery time-designed for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5404E6327HTSA1 datasheet, BAT5404E6327HTSA1 pinout, BAT5404E6327HTSA1 application, or BAT5404E6327HTSA1 equivalent, key selection criteria include its 400 mV forward voltage at 10 mA, 2 µA max reverse leakage at 25 V, 10 pF capacitance at 1 V, AEC-Q101 qualification, and thermal resistance of ≤345 K/W (junction-to-soldering point).
Technical Context
This Schottky diode operates with low forward voltage drop to minimize conduction loss in high-frequency switching paths and features guard ring protection for improved ruggedness against transient overstress. Its 5 ns reverse recovery time supports fast switching in clamp and protection functions without significant tail current.
The device exhibits stable reverse leakage (<2 µA at 25 V) across temperature and maintains low capacitance (≤10 pF at 1 V, 1 MHz) for minimal signal distortion in RF-coupled or high-speed analog interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports rail-to-rail clamping in 24 V automotive systems without breakdown. |
| Forward Voltage (VF) | 400 mV at 10 mA - reduces power loss and self-heating in always-on bias networks. |
| Reverse Recovery Time (trr) | 5 ns - enables reliable operation in >10 MHz signal path protection and fast-switching clamp circuits. |
| Reverse Leakage (IR) | 2 µA max at 25 V - ensures low standby current in precision sensor front-ends and battery-sensitive designs. |
| Junction-to-Soldering Point RthJS | ≤345 K/W - allows sustained 200 mA operation up to 71 °C ambient when mounted on standard PCB copper area. |
| Capacitance (CT) | 10 pF at 1 V, 1 MHz - preserves signal integrity in high-impedance analog inputs and ESD protection nodes. |
Pinout & Package
SOT-23 plastic surface-mount package with gull-wing leads; compact 2.9 mm × 1.3 mm footprint and 1.0 mm height; RoHS-compliant, lead-free termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node under forward bias | Connected to higher-potential side in clamp or isolation configurations; defines polarity-sensitive placement. |
| Cathode (Pin 2) | Current exit node under forward bias | Typically tied to reference rail (e.g., VCC or GND) in clamping; forms low-impedance discharge path. |
| NC / Heat Sink (Pin 3) | Non-connected terminal | Not internally bonded; serves mechanical support and thermal conduction via PCB pad contact. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Enhances surge robustness against ESD and line transients per IEC 61000-4-2 Level 4 without derating. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics with full temperature cycling and HTRB testing. |
| Low VF temperature coefficient | Forward voltage increases only ~0.2 mV/°C from −40 °C to 125 °C-enabling stable bias over full automotive range. |
| Pb-free, RoHS-compliant packaging | Meets EU Directive 2011/65/EU and J-STD-020 moisture sensitivity level 1 (MSL1) for reflow compatibility. |
Applications
| Automotive Sensor Signal Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Protecting analog outputs of pressure and temperature sensors in engine bay environments exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Fast clamping diode shunting transients to ground or supply rail during sub-100 ns events. Use Value: 5 ns trr and guard ring ensure no latch-up or parametric shift after repeated 1 kV EFT bursts. |
Use Scenario: Bidirectional ESD protection on USB 2.0 D+ and D− lines in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance (10 pF) Schottky clamp limiting voltage excursion below ±15 V during IEC 61000-4-2 contact discharge. Use Value: 400 mV VF avoids DC offset in data lines; 2 µA IR prevents signal leakage in idle state. |
| Power Rail Bias Isolation | Low-Power Metering Input Protection |
Use Scenario: Isolating auxiliary 3.3 V bias rails from main 5 V supply in telematics control units to prevent backfeed during brownout. IC Role / Device Role / Timing Role: Unidirectional blocking diode enabling independent rail sequencing and fault containment. Use Value: 30 V VR rating accommodates 5 V rail tolerance plus ripple; 200 mA IF supports typical MCU peripheral loads. |
Use Scenario: Protecting high-impedance ADC inputs in smart electricity meters subjected to lightning-induced surges on current-sense shunts. IC Role / Device Role / Timing Role: Low-leakage (2 µA max) clamp preventing input stage saturation while preserving measurement accuracy. Use Value: Stable VF vs. temperature ensures consistent clamping threshold across −25 °C to 70 °C meter operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54CLT3G | Lower VF (320 mV typ. @ 10 mA), same SOT-23, but not AEC-Q101 qualified. | Acceptable for industrial/commercial metering; unsuitable for automotive under hood use. | Select when AEC-Q101 is not required and lower conduction loss is prioritized. |
| BAT54C,215 | Same electrical specs, but packaged in SOT-323 (smaller footprint, higher RthJS = 445 K/W). | Limited to lower-power applications due to reduced thermal dissipation margin. | Choose only if board space is constrained and peak IF remains <100 mA at 70 °C ambient. |
Compared with SBAT54CLT3G and BAT54C,215, BAT5404E6327HTSA1 uniquely combines AEC-Q101 qualification, SOT-23 thermal performance (RthJS ≤345 K/W), and guaranteed 5 ns trr-making it the sole option for automotive-grade clamping where reliability and timing consistency are non-negotiable.

FAQ
Is BAT5404E6327HTSA1 pin-compatible with BAT54W?
No. BAT5404E6327HTSA1 is a single-anode, single-cathode SOT-23 device (Pin 1 = anode, Pin 2 = cathode). BAT54W is a common-anode dual diode in SOT-323, with different pin assignment and internal configuration-direct substitution would cause functional failure.
What is the maximum continuous forward current at 105 °C ambient?
At 105 °C ambient, the maximum continuous forward current is approximately 120 mA, derived from the IF vs. TS curve for BAT54-04 (TS ≤ 71 °C) and thermal derating using RthJS ≤345 K/W and Tj(max) = 150 °C.
Does this diode support bidirectional ESD clamping?
No. BAT5404E6327HTSA1 is a unidirectional Schottky diode. For bidirectional protection, two devices must be used in series opposition or a dedicated TVS array like ESD5Z5.0T1G should be selected.
Can BAT5404E6327HTSA1 replace BAT54-04W in the same PCB footprint?
Yes-both use SOT-23 packages with identical land pattern and pinout. However, BAT54-04W has higher thermal resistance (RthJS ≤117 K/W) and is rated for 117 °C junction temperature, whereas BAT5404E6327HTSA1 is rated for 71 °C-verify thermal margin before substitution.
