Product details
Overview
BAS4006WE6327 from Infineon Technologies is a silicon Schottky diode in SOT323 package configured as a common cathode dual diode, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW total power dissipation at TS ≤ 56°C, used for high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS4006WE6327 datasheet, BAS4006WE6327 pinout, BAS4006WE6327 application, or BAS4006WE6327 equivalent, key selection criteria include VF matching (≤20 mV), low CT (3 pF typ. @ 0 V), fast τrr (≤100 ps), and AEC-Q101 qualification for under-hood electronics.
Technical Context
This dual common-cathode Schottky diode integrates two matched junctions on a single die to enable precise voltage clamping and signal steering in bidirectional interfaces. Its low differential forward resistance (10 Ω typ. @ 10 kHz) and minimal charge carrier lifetime support sub-100 ps switching transitions.
The device operates across –55 °C to +125 °C ambient and achieves thermal resistance of ≤375 K/W (junction-to-soldering point), with derated forward current governed by package-specific junction temperature limits (TS ≤ 56°C for BAS40-06 variants).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - Maximum blocking voltage before breakdown; sets upper limit for clamp rail placement in 3.3 V/5 V logic protection. |
| IF (Forward Current) | 120 mA - Continuous DC current per diode; supports signal-level rectification and level shifting without thermal runaway. |
| VF @ 10 mA | 310–450 mV - Low forward drop enables efficient clamping with minimal voltage offset in precision analog paths. |
| CT @ 0 V, 1 MHz | 3 pF typ. - Low junction capacitance preserves signal integrity up to ~100 MHz in RF detector/mixer applications. |
| τrr (Reverse Recovery) | ≤100 ps - Ultrafast recovery eliminates switching-induced ringing in high-frequency sampling and clock distribution networks. |
| ∆VF (Matching) | ≤20 mV - Tight forward voltage matching between dual elements ensures balanced current sharing in differential clamp configurations. |
| AEC-Q101 Qualified | Yes - Validated for automotive use including engine control units and body electronics requiring robust ESD and thermal cycling performance. |
Pinout & Package
SOT323 package: 3-pin surface-mount plastic case with gull-wing leads; compact footprint (2.1 × 1.25 × 0.95 mm), moisture sensitivity level 1, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first clamping path; connects to protected signal line or RF input. |
| Pin 2 | Cathode (Common) | Shared reference node tied to clamp rail (e.g., VCC or bias voltage); defines conduction threshold for both diodes. |
| Pin 3 | Anode of Diode 2 | Input node for second clamping path; enables dual-rail or bidirectional transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Matched Dual Diodes | ∆VF ≤ 20 mV @ 10 mA ensures consistent clamping thresholds across both channels in differential receivers. |
| Ultra-Low Capacitance | CT = 3 pF typ. minimizes loading on high-impedance nodes such as antenna inputs or op-amp feedback paths. |
| Sub-100 ps Recovery | τrr ≤ 100 ps prevents distortion in >100 MHz signal paths like USB 2.0 data lines or CAN FD stubs. |
| AEC-Q101 Qualified | Validated for automotive Grade 2 (–40 °C to +105 °C ambient) operation with full ESD robustness (HBM ≥ 2 kV). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Single diode, SOD-123, VF = 370 mV @ 10 mA, CT = 4.5 pF, no VF matching spec | Lacks dual configuration and matching; requires two devices for common-cathode function | Select when board space allows discrete implementation and matching is non-critical |
| BAT54C | Common-cathode dual, SOT-23, VF = 350 mV @ 10 mA, CT = 10 pF, not AEC-Q101 qualified | Higher capacitance limits use above 30 MHz; unsuitable for automotive under-hood deployment | Prefer for cost-sensitive consumer-grade USB or audio clamping where qualification is not required |
Compared with NSR0230HT1G and BAT54C, BAS4006WE6327 delivers tighter VF matching, lower capacitance, and automotive qualification-making it optimal for space-constrained, high-frequency, safety-critical dual-clamp roles.

FAQ
What is the maximum allowable junction temperature for BAS4006WE6327?
The absolute maximum junction temperature is 150 °C. Derating begins at TS = 56 °C for this SOT323-packaged variant, with Ptot fixed at 250 mW below that threshold and linearly reduced above it per the thermal resistance curve (RthJS ≤ 375 K/W).
Is BAS4006WE6327 suitable for bidirectional TVS applications?
No-it is a unidirectional Schottky diode pair with common cathode configuration, designed for clamping to positive rails only. For bidirectional transient suppression, external series coupling or complementary diode arrangements are required; dedicated TVS devices like ESD5Z series are recommended instead.
Does BAS4006WE6327 have a specified ESD rating?
While not explicitly rated per HBM or CDM in the datasheet, its AEC-Q101 qualification confirms robustness against electrostatic discharge in automotive environments, and it is labeled as ESD-sensitive-requiring handling per IEC 61340-5-1 with grounded workstations and ionized air.
Can BAS4006WE6327 replace BAS40-06 in existing designs?
Yes-BAS4006WE6327 is the tape-and-reel packaging variant (E6327) of the BAS40-06 part, sharing identical electrical specs, SOT323 package, common-cathode configuration, and thermal limits; only packaging and reel orientation differ per JEDEC standard J-STD-020.
