Product details
Overview
BAT5405E6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-23 package configured as a single discrete device, rated for 30 V reverse voltage, 200 mA forward current, and 5 ns reverse recovery time, with typical forward voltage of 400 mV at 10 mA - used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5405E6327HTSA1 datasheet, BAT5405E6327HTSA1 pinout, BAT5405E6327HTSA1 application, or BAT5405E6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low VF at low IF, fast trr, thermal resistance (RthJS ≤ 445 K/W), and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode employs a guard ring–protected planar structure to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 25 V). Its low junction capacitance (10 pF at 1 V) and sub-5 ns reverse recovery support high-frequency signal clamping without ringing.
The device operates across –65 °C to +150 °C junction temperature range and is qualified per AEC-Q101 for automotive use; thermal derating curves confirm usable forward current up to 180 mA at TS = 120 °C for the BAT54-05 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports rail-to-rail clamping on 24 V automotive supply lines without breakdown. |
| Forward Current (IF) | 200 mA continuous - sufficient for biasing small-signal transducers and LED indicators. |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >10 MHz signal path protection without tail current. |
| Forward Voltage (VF) | 400 mV at 10 mA - minimizes power loss and self-heating in low-voltage analog front-ends. |
| Junction Capacitance (CT) | 10 pF at 1 V - preserves signal integrity in RF detector and high-speed logic interface applications. |
| Thermal Resistance (RthJS) | ≤445 K/W - defines maximum allowable power dissipation (230 mW) under specified board thermal conditions. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB testing. |
Pinout & Package
Package: SOT-23 (JEDEC TO-236AB), surface-mount, 3-terminal plastic case with standard pin pitch (0.95 mm) and thermal pad omitted. Dimensions: 2.9 × 1.3 × 1.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point under forward bias | Connected to higher-potential node during clamping or biasing; requires trace width ≥ 0.25 mm for 200 mA. |
| Cathode (Pin 2) | Current exit point under forward bias | Typically tied to reference (e.g., ground or signal return); serves as clamp sink in overvoltage events. |
| NC / Heat Sink (Pin 3) | No internal connection | Unused terminal; may be left floating or grounded for mechanical stability - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown at VR = 30 V, ensuring consistent reverse leakage <2 µA across temperature. |
| Pb-free RoHS-compliant packaging | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C). |
| Low forward voltage | VF ≤ 400 mV @ 10 mA enables operation in 3.3 V and 5 V systems without significant voltage drop. |
| Fast reverse recovery | trr ≤ 5 ns allows use in >10 MHz transient suppression without signal distortion or overshoot. |
| AEC-Q101 qualification | Validated for automotive underhood environments including 1000-hr HTOL, TC500, and ESD HBM ≥ 2 kV. |
Applications
| Automotive Sensor Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from load-dump transients and ESD events in vehicle door modules. IC Role / Device Role: Low-capacitance clamping diode shunting surge energy to ground before it reaches the IC input stage. Use Value: 10 pF CT and 5 ns trr prevent signal degradation while maintaining <2 µA IR at 25 V, preserving bus idle-state integrity. | Use Scenario: Bidirectional ESD protection on USB 2.0 D+ and D− lines in infotainment head units. IC Role / Device Role: Discrete Schottky clamp placed between data line and VBUS or ground to divert ±8 kV contact discharge. Use Value: 400 mV VF at 10 mA ensures minimal insertion loss; SOT-23 footprint fits tight 0.5-mm pitch routing constraints. |
| Low-Voltage Bias Isolation | Power Supply OR'ing |
Use Scenario: Isolating dual 3.3 V LDO outputs feeding separate MCU domains to prevent backfeed during brownout. IC Role / Device Role: Single Schottky diode in series with each LDO output to enforce unidirectional current flow. Use Value: 200 mA IF rating and 400 mV VF minimize voltage drop and thermal rise, enabling compact thermal design. | Use Scenario: OR'ing redundant 5 V supplies in telematics control units to maintain uptime during primary supply failure. IC Role / Device Role: Forward-biased Schottky diode on each supply path to block reverse current and enable seamless switchover. Use Value: 30 V VR rating accommodates 5 V rail tolerances plus margin; 230 mW Ptot supports continuous 200 mA operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54CLT3G | Same SOT-23 package, 30 V VR, but VF = 450 mV @ 10 mA; RthJS = 420 K/W; not AEC-Q101 qualified. | Lacks automotive qualification; suitable only for industrial/commercial designs with relaxed reliability requirements. | Select when cost sensitivity outweighs AEC-Q101 compliance and VF tolerance is >50 mV looser. |
| BAT54C,215 | Common-cathode dual configuration in SOT-23; VF = 370 mV @ 10 mA; RthJS = 345 K/W; AEC-Q101 qualified. | Provides two matched diodes in one package - ideal for differential signal clamping or dual-rail protection. | Choose when dual-diode topology reduces component count and layout area in balanced analog interfaces. |
Compared with SBAT54CLT3G and BAT54C,215, BAT5405E6327HTSA1 offers the strictest AEC-Q101 validation and lowest thermal resistance among single-diode SOT-23 Schottkys, making it optimal for thermally constrained automotive modules where single-device simplicity and reliability are prioritized.

FAQ
Is BAT5405E6327HTSA1 pin-compatible with BAT54C or BAT54A?
No - BAT5405E6327HTSA1 is a single-diode SOT-23 device (anode–cathode–NC), whereas BAT54C is a common-cathode dual diode and BAT54A is a common-anode dual. Pin 3 is NC in BAT5405E6327HTSA1 but carries an active terminal in dual variants; direct substitution will cause functional failure.
What is the maximum allowable soldering temperature profile for BAT5405E6327HTSA1?
The device complies with IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be limited to 60–150 seconds per JEDEC standard.
Does BAT5405E6327HTSA1 support bidirectional ESD protection?
No - it is a unidirectional Schottky diode. For bidirectional ESD clamping, two BAT5405E6327HTSA1 devices must be connected in series opposition (anode-to-anode), or a dedicated TVS array like ESD5Z5.0T1G should be used instead.
How does thermal performance differ between BAT5405E6327HTSA1 and BAT5405W?
BAT5405E6327HTSA1 (SOT-23) has RthJS ≤ 445 K/W and max TS = 48 °C, while BAT5405W (SOT-323) has RthJS ≤ 175 K/W and max TS = 110 °C. The smaller SOT-23 case limits heat dissipation, requiring stricter board copper area and airflow in high-power applications.
