Product details
Overview
BAS4005WE6327BTSA1 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as a single discrete device, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW power dissipation at TS ≤ 31 °C. It serves as a high-speed switching diode for voltage clamping and signal mixing in automotive and industrial control circuits.
For engineers reviewing the BAS4005WE6327BTSA1 datasheet, BAS4005WE6327BTSA1 pinout, BAS4005WE6327BTSA1 application, or BAS4005WE6327BTSA1 equivalent, key selection criteria include its low 380–500 mV forward voltage at 10 mA, 3–5 pF capacitance at 0 V, 100 ps reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast switching (τrr ≤ 100 ps) and minimal forward conduction loss. Its low differential forward resistance (RF = 10 Ω typ. at 10 mA) supports efficient signal rectification in RF detector and level-shifting applications.
The device operates across –55 °C to +150 °C with a maximum junction temperature of 150 °C and thermal resistance RthJS ≤ 475 K/W (BAS40-05 variant), enabling use in thermally constrained PCB layouts where thermal management is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Supports clamping and protection in 24 V automotive and 36 V industrial supply rails. |
| Forward Current (IF) | 120 mA DC - Enables continuous operation in low-power signal path and biasing circuits. |
| Forward Voltage (VF) | 380–500 mV @ 10 mA - Reduces conduction loss and self-heating in high-frequency detector stages. |
| Diode Capacitance (CT) | 3–5 pF @ 0 V, 1 MHz - Minimizes signal distortion in RF mixing and high-speed digital clamping. |
| Reverse Recovery Time (τrr) | ≤ 100 ps - Ensures clean edge fidelity in >100 MHz switching and pulse shaping applications. |
| Thermal Resistance (RthJS) | ≤ 475 K/W - Requires careful thermal pad layout on PCB to maintain TJ ≤ 150 °C at full load. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SOT23 (JEDEC TO-236AB), surface-mount, 3-terminal plastic package with gull-wing leads. Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC) - confirmed per Infineon BAS40-05 product definition and marking code "45s".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Forward current entry point; connects to higher-potential node in clamping or rectifier configuration. |
| Pin 2 | Cathode | Forward current exit and reverse-blocking terminal; ties to reference or ground in protection circuits. |
| Pin 3 | NC (No Connect) | Internally isolated; must remain unconnected to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 380–500 mV @ 10 mA enables <100 mW conduction loss in 120 mA paths. |
| Ultra-fast switching | τrr ≤ 100 ps supports clean signal integrity in >100 MHz RF detector and mixer stages. |
| Low junction capacitance | CT = 3–5 pF minimizes loading on high-impedance nodes in precision analog front-ends. |
| AEC-Q101 qualified | Validated for automotive underhood environments including thermal cycling and humidity exposure. |
| Pb-free & RoHS compliant | SOD323/SOT23 package meets EU Directive 2011/65/EU without lead-based solder compatibility issues. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Clamping transient spikes on LIN bus lines during load dump events. IC Role / Device Role / Timing Role: Fast-switching Schottky clamp protecting transceiver I/O pins from >40 V surges. Use Value: Prevents latch-up and ESD damage with sub-100 ps response and 40 V standoff rating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Lower VR = 30 V; higher IF = 200 mA; same SOT23 package; no AEC-Q101 qualification. | Not suitable for 40 V automotive clamping; acceptable for consumer-grade 3.3/5 V rail OR-ing. | Select only if AEC-Q101 is not required and system VR stays below 30 V. |
| RB521S30T2R | VR = 30 V; VF = 370 mV @ 10 mA; CT = 4.5 pF; AEC-Q101 qualified; SOD-523 package (smaller footprint). | Smaller size limits thermal mass; lower VR restricts use in 24 V+ systems. | Prefer for space-constrained boards where 30 V rating suffices and thermal derating is managed. |
Compared with NSR0230HT1G and RB521S30T2R, BAS4005WE6327BTSA1 uniquely delivers 40 V standoff with AEC-Q101 compliance in SOT23 - making it the only option among the three for robust 24 V automotive clamping without package or qualification trade-offs.

FAQ
Is BAS4005WE6327BTSA1 pin-compatible with other BAS40 variants?
Yes - all BAS40-xx variants in SOT23 share identical pinout (Anode–Cathode–NC), but thermal derating differs by suffix (e.g., BAS40-05 requires TS ≤ 31 °C). Mechanical fit is guaranteed, though electrical and thermal limits must be verified per variant.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature remains 150 °C regardless of pulse duration. For repetitive pulses, peak current must be limited using the IFmax/IFDC vs. tp curves in Infineon's EHD07166 chart, with duty cycle D ≤ 0.5 to avoid thermal runaway.
Does BAS4005WE6327BTSA1 require special ESD handling?
Yes - it is classified as ESD-sensitive (HBM Class 2, ≥2 kV). Handling requires grounded workstations, ionized air, and static-dissipative packaging. The "ESD sensitive device" warning on Infineon's datasheet applies directly to this part number.
Can BAS4005WE6327BTSA1 replace BAS40-05W in existing designs?
No - BAS40-05W uses SOT323 package with different thermal resistance (RthJS ≤ 205 K/W) and higher TS limit (98 °C). Substituting the SOT23 BAS4005WE6327BTSA1 risks exceeding junction temperature unless board-level thermal design is revalidated.
