Product details
Overview
BAS40-06WE6327 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as a common anode dual diode, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW power dissipation at TS ≤ 56°C, used for high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS40-06WE6327 datasheet, BAS40-06WE6327 pinout, BAS40-06WE6327 application, or BAS40-06WE6327 equivalent, key selection criteria include reverse leakage (≤1 µA @ 30 V), low forward voltage (310–720 mV @ 1–40 mA), diode capacitance (3 pF typ. @ 0 V), fast recovery time (≤100 ps), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual common-anode Schottky diode enables bidirectional clamping and rail-to-rail signal steering in compact automotive interface nodes. Its low differential forward resistance (10 Ω typ. @ 10 kHz) and minimal charge carrier lifetime (≤100 ps) support sub-nanosecond switching transitions.
The device operates across –55 °C to +125 °C ambient, with junction temperature limited to 150 °C and thermal resistance from junction to soldering point ≤375 K/W - optimized for PCB-mounted thermal management in space-constrained engine control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 40 V - supports clamping of transients up to automotive ISO 7637-2 Pulse 1/2a levels without breakdown. |
| Forward Current | 120 mA DC - sufficient for logic-level signal routing and sensor biasing in low-power ECUs. |
| Forward Voltage | 310–720 mV @ 1–40 mA - minimizes conduction loss and self-heating in always-on monitoring paths. |
| Reverse Leakage | ≤1 µA @ 30 V - ensures negligible standby current in battery-sensitive applications like CAN wake-up receivers. |
| Diode Capacitance | 3 pF typ. @ 0 V, 1 MHz - preserves signal integrity in >100 MHz RF detector and mixer front-ends. |
| Recovery Time | ≤100 ps - enables clean edge preservation in high-frequency clock injection and pulse shaping circuits. |
| Thermal Resistance | ≤375 K/W (junction-to-soldering point) - defines maximum allowable trace copper area for thermal relief on 2-layer PCBs. |
Pinout & Package
Package: SOT23 - surface-mount plastic package with gull-wing leads, footprint compatible with JEDEC TO-236AB, suitable for reflow assembly and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input node for first diode path | Accepts positive-going transient or signal to be clamped to cathode reference. |
| Cathode (Pin 2) | Common cathode connection | Shared return path for both diodes; must be tied to stable reference (e.g., VCC or GND). |
| Anode 2 (Pin 3) | Input node for second diode path | Enables dual-direction clamping or independent signal routing from two sources to one rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including thermal cycling, humidity, and mechanical shock per JESD22 standards. |
| RoHS-compliant packaging | Pb-free SOT23 construction with matte tin lead finish, compatible with lead-free reflow profiles (J-STD-020). |
| Low VF matching | ΔVF ≤ 20 mV @ 10 mA - ensures balanced current sharing in dual-path protection or precision rectification. |
| ESD-sensitive handling | Class H1B (≥2 kV HBM) - requires grounded workstation, ionized air, and static-dissipative packaging during assembly. |
Applications
| Automotive CAN Transceiver Protection | High-Speed Logic-Level Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L pins against ESD and load dump transients in body control modules. IC Role / Device Role / Timing Role: Dual common-anode Schottky clamp limiting bus voltage excursions to ±0.3 V beyond supply rails. Use Value: Prevents latch-up in transceivers while maintaining <1 ns propagation delay impact due to ≤3 pF capacitance. |
Use Scenario: Level-shifting and overvoltage clamping between 3.3 V microcontroller GPIO and 5 V peripheral interfaces. IC Role / Device Role / Timing Role: Bidirectional voltage limiter referenced to either VCC or GND depending on signal polarity. Use Value: Eliminates need for external pull-up resistors and discrete Zener networks, reducing BOM count by 3 components per channel. |
| RF Signal Detector Front-End | Engine Control Unit Sensor Biasing |

Use Value: Enables <±0.5% current matching between redundant sensor channels, supporting ASIL-B functional safety compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Single diode, 30 V VR, 200 mA IF, 0.45 pF CT - lower capacitance but no dual configuration. | Lacks common-anode dual topology; requires two devices for same functionality. | Preferred when ultra-low capacitance dominates over board space and layout simplicity. |
| BAT54CW | Common-cathode dual Schottky, 30 V VR, 200 mA IF, 10 pF CT - higher capacitance, different polarity orientation. | Requires circuit redesign to accommodate cathode-common vs. anode-common topology. | Used where existing layouts already use BAT54-series footprints and higher leakage tolerance exists. |
Compared with NSR0230HT1G and BAT54CW, BAS40-06WE6327 uniquely delivers AEC-Q101 qualification, 40 V rating, and common-anode dual integration in SOT23 - enabling single-component bidirectional clamping in thermally constrained automotive domains without topology compromise.

FAQ
Is BAS40-06WE6327 pin-compatible with BAS40-06?
Yes - both share identical SOT23 package and common-anode pinout (Anode1–Cathode–Anode2). The "E6327" suffix denotes tape-and-reel packaging per Infineon's ordering convention and does not affect electrical or mechanical compatibility.
What is the maximum allowable soldering temperature profile for BAS40-06WE6327?
The device complies with JEDEC J-STD-020D for moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s before and after peak, per Infineon's SOT23 assembly guidelines.
Does BAS40-06WE6327 require derating above 25°C ambient?
Yes - its 120 mA forward current rating applies only at TA = 25°C. Derating begins immediately above this temperature, reaching 0 mA at 125°C ambient, per the IF vs. TS curve in Figure 6 of the datasheet for BAS40-06.
Can BAS40-06WE6327 replace BAT54AW in an existing design?
No - BAT54AW is common-cathode, whereas BAS40-06WE6327 is common-anode. Direct substitution would invert clamping polarity and risk circuit malfunction unless board-level rewiring or schematic revision is performed.
