Product details
Overview
BAT6405E6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common anode dual diode in SCD80 (SOT-23 variant) 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 BAT6405E6327HTSA1 datasheet, BAT6405E6327HTSA1 pinout, BAT6405E6327HTSA1 application, or BAT6405E6327HTSA1 equivalent, key selection criteria include its 350–520 mV forward voltage at 30 mA, 4–6 pF capacitance at 1 V, AEC-Q101 qualification, and thermal resistance of ≤355 K/W (junction-to-soldering point) under specified mounting conditions.
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 trr. Its low VF and low CT enable high-efficiency clamping in 12 V automotive analog front-ends where leakage and parasitic capacitance must be minimized.
The device operates up to 150 °C junction temperature and is qualified per AEC-Q101 for automotive use. Thermal derating curves confirm usable forward current down to 36 °C case temperature for the BAT64-05 variant, reflecting its thermally constrained SCD80 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability in clamping or isolation paths without breakdown |
| Forward Current (IF) | 250 mA - Continuous DC current handling capacity at TA = 25°C |
| Reverse Recovery Time (trr) | 5 ns - Enables operation in >10 MHz signal routing and fast transient suppression |
| Forward Voltage (VF) | 350–520 mV @ 30 mA - Low conduction loss critical for battery-sensitive metering and sensor bias |
| Diode Capacitance (CT) | 4–6 pF @ 1 V, 1 MHz - Minimizes signal distortion in RF and high-speed analog interfaces |
| Junction Temp (Tj) | 150 °C - Supports under-hood automotive deployment with appropriate PCB copper area |
| Thermal Resistance (RthJS) | ≤355 K/W - Requires defined solder pad layout to maintain safe junction temperature at full load |
Pinout & Package
Package: SCD80 - Small-outline surface-mount package with 3 terminals, 1.7 mm × 0.8 mm body, cathode-marked leadframe, and optimized thermal path for power dissipation in space-constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Primary input node for first clamping path; connects to protected signal line |
| Pin 2 | Cathode (Common) | Shared return path for both diodes; must be routed to low-impedance ground or bias rail |
| Pin 3 | Anode of Diode 2 | Second independent input node enabling dual-rail or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive electronics including engine control, body modules, and ADAS sensors |
| Integrated Diffused Guard Ring | Prevents premature edge breakdown under high dv/dt, improving reliability in noisy environments |
| Low Forward Voltage | 350 mV typ. @ 30 mA enables <1% voltage drop in precision bias networks |
| Pb-Free (RoHS Compliant) | Meets EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3 moisture sensitivity |
| ESD-Sensitive Handling | Class H2 (≥2 kV HBM); requires grounded workstations and ionized air during assembly |
Applications

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 Schottky in SOT-23; 30 V VR, 200 mA IF, 4 pF CT, RthJS ≤ 115 K/W | Lower voltage rating and single-diode topology limit dual-rail or differential use | Select when only one clamping path is needed and thermal budget allows higher power density |
| NSR0230HT1G | Single Schottky in SOD-323; 30 V VR, 200 mA IF, 3.5 pF CT, VF = 370 mV @ 10 mA | Smaller package reduces board area but lacks dual-diode integration and AEC-Q101 certification | Choose for cost-sensitive consumer applications where automotive qualification is not required |
Compared with BAR63-02W and NSR0230HT1G, BAT6405E6327HTSA1 uniquely combines AEC-Q101 compliance, dual common-anode topology, and 40 V rating-enabling single-component protection of differential automotive sensor pairs without external routing compromises.

FAQ
What is the marking code for BAT6405E6327HTSA1?
The top-side laser marking is "65s", as confirmed in the official Infineon datasheet revision 2007-06-11. This 3-character code identifies the BAT64-05 variant within the BAT64 series and is located adjacent to the cathode bar on the SCD80 package.
Is BAT6405E6327HTSA1 suitable for 24 V commercial vehicle applications?
Yes - its 40 V reverse voltage rating provides 1.67× margin above nominal 24 V system voltage and meets ISO 16750-2 pulse test requirements for load dump (up to 35 V for 400 ms). Derating curves confirm safe operation up to 125 °C ambient when mounted per recommended footprint.
Does this part require special ESD handling during PCB assembly?
Yes - BAT6405E6327HTSA1 is classified as ESD-sensitive (H2, ≥2 kV HBM). Assembly requires grounded wrist straps, ionized airflow, static-dissipative mats, and ESD-safe feeders. The device must not be touched with bare hands or placed on non-grounded surfaces before reflow.
Can BAT6405E6327HTSA1 replace BAT64-05W in existing designs?
No - BAT6405E6327HTSA1 uses the SCD80 package (thermal resistance ≤355 K/W), while BAT64-05W uses SOT-323 (≤104 K/W). Substituting without thermal redesign risks exceeding 150 °C junction temperature at full 250 mA load due to 3.4× higher RthJS.
