Product details
Overview
BAT64-02W E6327 from Infineon Technologies is a silicon Schottky diode in SCD80 (SOT-23 variant) package, configured as a single anode-cathode device with 40 V reverse voltage rating, 250 mA forward current, and 5 ns reverse recovery time. It delivers low forward voltage (320–500 mV at 10–100 mA) and 4 pF capacitance at 1 V, enabling use in high-speed clamping and bias isolation circuits for automotive sensor interfaces.
For engineers reviewing the BAT64-02W E6327 datasheet, BAT64-02W E6327 pinout, BAT64-02W E6327 application, or BAT64-02W E6327 equivalent, key selection criteria include its AEC-Q101 qualification, thermal resistance of ≤115 K/W (junction-to-soldering point), and guaranteed 150 °C junction temperature - critical for under-hood automotive signal conditioning and ESD protection.
Technical Context
This Schottky diode employs a planar silicon structure with integrated diffused guard ring to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 30 V, 25 °C). Its low series inductance (0.6 nH) and minimal junction capacitance support RF and fast-switching applications up to ~1 GHz.
The device operates across –55 °C to +150 °C storage and junction temperature ranges, with thermal derating curves confirming 250 mA continuous forward current at TS ≤ 121 °C - validated for surface-mount soldering on FR-4 PCBs with standard reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping in 24 V automotive systems with 2× safety margin against transients. |
| Forward Current (IF) | 250 mA - sufficient for biasing Hall-effect sensors and analog front-end protection paths. |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >10 MHz signal routing without tail current distortion. |
| Junction Capacitance (CT) | 4 pF @ 1 V, 1 MHz - preserves signal integrity in RF detector and antenna switch control lines. |
| Forward Voltage (VF) | 320 mV @ 10 mA - minimizes power loss and self-heating in always-on metering circuits. |
| Thermal Resistance (RthJS) | ≤115 K/W - allows direct thermal coupling to PCB copper for sustained operation at 121 °C case temperature. |
| Junction Temperature (Tj) | 150 °C - meets AEC-Q101 stress test requirements for under-hood electronics reliability. |
Pinout & Package
Package: SCD80 - ultra-small plastic surface-mount package (2.5 × 1.3 × 0.9 mm), identical footprint to SOT-23 but optimized for lower inductance and improved thermal conduction via exposed cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal | Connected to positive rail or signal source during forward conduction; requires trace width ≥0.3 mm for 250 mA DC handling. |
| Cathode (Pin 2) | Current exit terminal / reference node | Exposed metal pad on bottom surface - must be soldered to ≥100 mm² copper pour for thermal dissipation and EMI shielding. |
| No-Connect (Pin 3) | Structural support only | Internally unconnected; serves mechanical anchoring and alignment - no electrical function or routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated diffused guard ring | Eliminates premature edge breakdown at VR = 40 V, ensuring consistent reverse leakage <2 µA across production lots. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTGB, TCT, and ESD HBM ≥2 kV - suitable for engine control and ADAS subsystems. |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C, 10 s). |
| Low series inductance (LS) | 0.6 nH - reduces voltage overshoot during nanosecond-scale transient clamping in CAN/LIN bus protection. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W E6327 | Same SCD80 package, but 30 V VR and 3 ns trr; VF = 290 mV @ 10 mA. | Better suited for sub-12 V logic-level clamping where speed outweighs voltage margin. | Select when system transients stay below 24 V and <3 ns recovery is mandatory. |
| NSR0230HT1G | SOT-23 package (not SCD80), 30 V VR, 2 ns trr, VF = 330 mV @ 10 mA, RthJS = 200 K/W. | Higher thermal resistance limits continuous current to 150 mA at 100 °C ambient. | Choose only for space-constrained non-automotive designs where 2 ns speed justifies reduced thermal performance. |
Compared with BAR63-02W E6327 and NSR0230HT1G, BAT64-02W E6327 provides superior voltage margin (40 V vs. 30 V) and thermal capability (≤115 K/W vs. ≥200 K/W), making it the preferred choice for AEC-Q101-compliant 24 V automotive systems requiring robust surge immunity and long-term bias stability.

FAQ
What is the maximum allowable soldering temperature profile for BAT64-02W E6327?
The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature of 260 °C for ≤10 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C shall be 60–150 seconds. Thermal shock testing confirms no delamination or parameter shift after three cycles.
Does BAT64-02W E6327 require external ESD protection in addition to its built-in guard ring?
No - the integrated diffused guard ring and AEC-Q101 qualification cover HBM ≥2 kV and CDM ≥1 kV. However, for IEC 61000-4-2 Level 4 (±15 kV contact), a series resistor (≥100 Ω) is recommended upstream to limit peak current during discharge events.
Can BAT64-02W E6327 replace BAT64-04W in a common-cathode dual-diode layout?
No - BAT64-02W is a single-diode configuration in SCD80, while BAT64-04W is a dual-series diode in SOT-323. Pin count, internal topology, and package dimensions differ fundamentally; no direct PCB footprint or functional substitution is possible without schematic and layout revision.
How does the 0.6 nH series inductance affect performance in 2.4 GHz ISM band applications?
At 2.4 GHz, 0.6 nH contributes only 9 Ω inductive reactance, which is negligible versus typical 50 Ω system impedance. Measured S-parameters confirm <0.2 dB insertion loss up to 3 GHz when mounted per recommended footprint - validating suitability for Bluetooth/Wi-Fi antenna switch control paths.
