Product details
Overview
BAT5406E6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common-anode dual diode in SOT-323 package, rated for 30 V reverse voltage, 200 mA forward current, and 5 ns reverse recovery time, used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5406E6327HTSA1 datasheet, BAT5406E6327HTSA1 pinout, BAT5406E6327HTSA1 application, or BAT5406E6327HTSA1 equivalent, key selection criteria include its common-anode topology, 400 mV forward voltage at 10 mA, 10 pF capacitance at 1 V, AEC-Q101 qualification, and thermal resistance of 145 K/W (junction-to-soldering point).
Technical Context
This dual Schottky diode integrates two anode-connected junctions in a single SOT-323 package, enabling compact bidirectional clamping or dual-rail protection without external wiring. Its guard ring structure ensures stable breakdown behavior and robust ESD tolerance.
The device operates with low forward voltage drop across its full rated current range (0.1–100 mA), maintains sub-10 pF capacitance up to 10 V reverse bias, and achieves 5 ns reverse recovery under standardized 10 mA switching conditions-critical for high-frequency signal integrity in automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 30 V - supports clamping in 24 V automotive systems with margin against transients |
| Forward Current | 200 mA - sufficient for biasing Hall-effect sensors and small-signal interface circuits |
| Reverse Recovery Time | 5 ns - enables clean switching in >10 MHz signal paths without ringing or overshoot |
| Forward Voltage | 400 mV @ 10 mA - minimizes power loss and self-heating in always-on sensor bias networks |
| Diode Capacitance | 10 pF @ 1 V - preserves bandwidth in high-impedance analog front-ends (e.g., LIN bus receivers) |
| Junction Temp Limit | 150 °C - meets under-hood thermal requirements per AEC-Q101 stress testing |
| Thermal Resistance | 145 K/W (RthJS) - allows sustained 150 °C operation with standard PCB copper area |
Pinout & Package
SOT-323 (SC-70) 3-pin plastic package with gull-wing leads; moisture sensitivity level MSL3; RoHS-compliant, lead-free termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Common connection point for both diodes' anodes; ties to positive rail or reference voltage |
| Pin 2 | Cathode of Diode 1 | Provides first clamping path to ground or low-side reference; routed to protected node |
| Pin 3 | Cathode of Diode 2 | Enables independent second clamping path-used for dual-rail protection or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown and improves long-term reliability under repeated surge stress |
| AEC-Q101 qualification | Validated for automotive applications including engine control, lighting, and ADAS sensor interfaces |
| Low VF temperature stability | VF drift < 0.2 mV/°C over −40 °C to +125 °C - ensures consistent biasing across ambient range |
| Sub-10 pF capacitance | Maintains >30 MHz signal bandwidth in 50 Ω systems without added impedance mismatch |
| Common-anode dual configuration | Reduces board space vs. discrete diodes and eliminates routing asymmetry in differential protection |
Applications
| Automotive LIN Transceiver Protection | USB Port ESD Clamping |
|---|---|
Use Scenario: Protecting LIN bus physical layer from ±30 kV ESD events and load-dump transients in door module ECUs. IC Role / Device Role / Timing Role: Dual clamping diode shunting transient energy to VCC and GND rails while preserving signal integrity on LIN data line. Use Value: Prevents latch-up in transceiver ICs by limiting voltage excursion to ≤3.3 V during 8/20 µs surges. |
Use Scenario: Safeguarding USB 2.0 D+/D− lines against IEC 61000-4-2 contact discharge in portable diagnostic tools. IC Role / Device Role / Timing Role: Common-anode configuration enables symmetrical bidirectional clamping without polarity constraints. Use Value: Achieves <5 ns response with <10 pF loading - avoids signal distortion at 480 Mbps full-speed USB timing. |
| Industrial Sensor Bias Isolation | DC-DC Converter Feedback Path Protection |
Use Scenario: Isolating precision current-sense amplifier inputs from supply rail noise in motor drive current loops. IC Role / Device Role / Timing Role: Low-VF Schottky barrier blocks reverse leakage while passing bias current with minimal offset error. Use Value: Limits input offset shift to <1 µV due to diode leakage (<2 µA @ 25 V), preserving 16-bit ADC accuracy. |
Use Scenario: Protecting optocoupler feedback pins in isolated flyback converters from output overvoltage spikes. IC Role / Device Role / Timing Role: Fast trr and low CT prevent false triggering of regulation loop during transient events. Use Value: Enables stable regulation under 100 V/µs dv/dt transients without oscillation or dropout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Same SOT-323, common-anode, but 35 V VR rating and 6 ns trr; higher VF (420 mV @ 10 mA) | Marginally better transient headroom; slightly reduced efficiency in low-power bias networks | Preferred where 35 V system margin is required and 20 mV VF penalty is acceptable |
| NSR0230HT1G | Single-diode SOD-123, 30 V VR, 200 mA IF, 4 ns trr, but no dual configuration | Requires two devices for dual-rail use; increases layout area and parasitic inductance | Only suitable when board space permits discrete placement and dual functionality is not needed |
Compared with SBAT54DW-7-F and NSR0230HT1G, BAT5406E6327HTSA1 uniquely delivers AEC-Q101 qualification, optimized 5 ns trr, and integrated common-anode topology-making it the only choice for space-constrained, automotive-grade dual-clamp designs requiring guaranteed reliability.

FAQ
Is BAT5406E6327HTSA1 qualified for automotive use?
Yes, BAT5406E6327HTSA1 is fully qualified to AEC-Q101 standards, including stress tests for temperature cycling, humidity, and mechanical shock. It is rated for operation from −40 °C to +150 °C and approved for use in engine bay, chassis, and interior control modules per Infineon's qualification report Q101-001-2011.
What is the maximum continuous forward current at 125 °C ambient?
At TA = 125 °C, the maximum continuous forward current is 100 mA, derived from the derating curve in Figure 8 of the datasheet. This limit ensures junction temperature remains below 150 °C given the device's RthJS of 145 K/W and typical PCB thermal design.
Can BAT5406E6327HTSA1 replace BAT54-06W in existing designs?
Yes-BAT5406E6327HTSA1 is the tape-and-reel packaged version of BAT54-06W, sharing identical electrical specs, SOT-323 footprint, common-anode pinout, and AEC-Q101 qualification. The "E6327" suffix denotes packaging format; no layout or schematic changes are required for migration.
Does this diode support bidirectional ESD protection?
No-it provides unidirectional clamping from cathodes to anode (i.e., from protected node to VCC). For true bidirectional protection, a TVS diode or back-to-back Schottky pair is required; BAT5406E6327HTSA1 is intended for rail-to-rail clamping where one side is referenced to VCC.
