Product details
Overview
BAT6405WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common-anode dual diode in SOT-323 (SC-70) package, rated for 40 V reverse voltage, 250 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 BAT6405WH6327XTSA1 datasheet, BAT6405WH6327XTSA1 pinout, BAT6405WH6327XTSA1 application, or BAT6405WH6327XTSA1 equivalent, key selection criteria include its 4 pF typical junction capacitance at 1 V, 370 mV forward voltage at 30 mA, AEC-Q101 qualification, RoHS-compliant lead-free packaging, and thermal resistance of 155 K/W (junction-to-soldering point).
Technical Context
This dual common-anode Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports fast switching with sub-5 ns reverse recovery. Its low VF (370 mV typ. @ 30 mA) and low CT (4 pF typ. @ 1 V) enable high-efficiency clamping in precision analog front-ends.
The device operates across –55 °C to +150 °C junction temperature range and is qualified per AEC-Q101 for automotive applications; thermal design must account for its 155 K/W RthJS and 104 °C max soldering-point temperature rating.

Applications
| Automotive Sensor Protection | Industrial Analog Front-End Clamping |
|---|---|
Use Scenario: Protecting Hall-effect and crankshaft position sensor outputs from load-dump transients in 12 V/24 V vehicle electrical systems. IC Role / Device Role / Timing Role: Dual common-anode Schottky clamp limiting voltage excursions to ≤40 V while preserving signal rise time. Use Value: Prevents op-amp input damage without adding propagation delay or signal distortion due to 5 ns trr and 4 pF CT. | Use Scenario: Bias isolation for dual-channel instrumentation amplifiers in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Common-cathode dual diode providing independent DC path blocking for two differential inputs referenced to system ground. Use Value: Enables simultaneous channel protection with matched VF (±15 mV) and eliminates cross-talk via isolated anodes. |
| Portable Meter ESD Suppression | Low-Power Signal Rectification |
Use Scenario: ESD transient suppression on LCD segment driver lines in handheld multimeters and energy meters. IC Role / Device Role / Timing Role: Fast-recovery Schottky clamp shunting ±8 kV HBM transients to ground before IC input structures fail. Use Value: Survives repeated ESD events without parameter shift thanks to integrated guard ring and 150 °C Tj rating. | Use Scenario: Full-wave rectification of low-amplitude AC signals (<100 mV) from thermocouples or piezoelectric sensors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Single common-cathode diode, 30 V VR, 3 pF CT, 115 K/W RthJS | Lacks dual-anode topology; requires two devices for same function | Choose when board area allows discrete placement and lower capacitance is critical |
| NSR0230HT1G | Single Schottky, 30 V VR, 250 mA IF, 0.45 V VF @ 100 mA, SOD-323 | No dual configuration; higher VF increases conduction loss in bias networks | Prefer for cost-sensitive consumer applications where AEC-Q101 is not required |
Compared with BAR63-02W and NSR0230HT1G, BAT6405WH6327XTSA1 uniquely delivers dual common-anode functionality in one SOT-323 footprint with AEC-Q101 validation, enabling compact, automotive-grade clamping without layout duplication or reliability compromise.

FAQ
What is the pin configuration of BAT6405WH6327XTSA1?
It is a 3-pin SOT-323 device with pins 1 and 2 as independent anodes and pin 3 as the common cathode. The cathode is marked by a band adjacent to pin 3 on the package top surface, consistent with JEDEC SC-70 outline and Infineon's SCD80 footprint.
Is BAT6405WH6327XTSA1 suitable for 125 °C ambient operation?
Yes - its junction temperature rating is 150 °C and it is rated for 104 °C maximum soldering-point temperature. At TA = 125 °C, derated forward current is ~140 mA per diode based on its 155 K/W RthJS and thermal profile in standard FR-4 PCB mounting.
Does this diode require special handling for ESD sensitivity?
Yes - it is classified as ESD-sensitive (HBM >2 kV). Handling requires grounded workstations, ionized air, and static-dissipative packaging. The datasheet explicitly states "ESD sensitive device, observe handling precaution!" and recommends IEC 61340-5-1 compliant procedures during assembly.
How does the diffused guard ring improve performance?
The integrated diffused guard ring controls electric field distribution at the diode periphery, suppressing edge-initiated avalanche and enabling stable 40 V reverse breakdown. This improves long-term reliability under repetitive transient stress and eliminates parameter drift observed in non-guarded Schottky structures.
