Product details
Overview
BAT64-06WE6327 from Infineon is a silicon Schottky diode in SCD80 package configured as a common anode dual diode, 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 BAT64-06WE6327 datasheet, BAT64-06WE6327 pinout, BAT64-06WE6327 application, or BAT64-06WE6327 equivalent, key selection criteria include common-anode topology, low VF (350 mV typ. @ 1 mA), 4–6 pF capacitance at 1 V, AEC-Q101 qualification, and thermal resistance of ≤155 K/W (junction-to-soldering point).
Technical Context
This dual Schottky diode integrates a diffused guard ring to enhance ESD robustness and reverse leakage stability. Its common-anode configuration enables symmetrical clamping of bidirectional analog signals while maintaining low forward voltage drop across both diodes.
The device operates with junction temperature up to 150 °C and supports surge currents up to 800 mA (non-repetitive, t ≤ 10 ms). Thermal design must account for its RthJS ≤ 155 K/W and derated forward current versus soldering point temperature (TS ≤ 111 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 40 V - maximum blocking capability for 3.3 V/5 V rail protection and sensor interface clamping |
| Forward Current | 250 mA - continuous DC current handling per diode under TS ≤ 111 °C |
| Reverse Recovery Time | 5 ns - enables fast switching in RF detector and high-speed signal clamp applications |
| Forward Voltage | 350 mV (typ. @ 1 mA) - minimizes conduction loss in low-voltage bias networks |
| Diode Capacitance | 4–6 pF @ 1 V, 1 MHz - preserves bandwidth in RF/metering front-end signal paths |
| Junction Temp | 150 °C - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics reliability per stress test requirements |
Pinout & Package
Package: SCD80 - surface-mount plastic package with gull-wing leads, 2 mm pitch, cathode marked on top surface, optimized for automated assembly and thermal performance (RthJS ≤ 155 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input node for first diode | Connected to signal path requiring clamping or bias isolation |
| Cathode (Pin 2) | Common cathode terminal | Shared return path for both diodes; ties to reference or ground plane |
| Anode 2 (Pin 3) | Input node for second diode | Enables dual-channel symmetric clamping or independent bias control |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Allows matched clamping of differential or complementary signals without discrete pairing |
| Low forward voltage (350 mV typ. @ 1 mA) | Reduces power loss and self-heating in battery-powered sensor interfaces |
| Integrated diffused guard ring | Improves reverse leakage stability and ESD tolerance (HBM > 8 kV per AEC-Q101) |
| Pb-free, RoHS-compliant packaging | Meets automotive and industrial environmental compliance mandates without lead-based solder compatibility trade-offs |
| 5 ns reverse recovery time | Supports >100 MHz signal integrity in RF detector and metering front ends |

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; VF = 320 mV @ 1 mA; CT = 0.3 pF @ 1 V | Lacks dual configuration; lower capacitance but no common-anode symmetry | Preferred where ultra-low CT dominates over dual-channel matching |
| BAT54CW | Common-cathode dual in SOT-323; VF = 370 mV @ 10 mA; VR = 30 V | Lower reverse voltage rating; different polarity configuration affects PCB layout | Used when common-cathode topology aligns with existing ground-referenced clamp architecture |
Compared with BAR63-02W and BAT54CW, BAT64-06WE6327 uniquely delivers common-anode duality with AEC-Q101 qualification, 40 V VR, and balanced VF/CT trade-off-making it optimal for automotive bidirectional signal protection where layout symmetry and reliability are critical.
