Product details
Overview
BAS4007WE6327BTSA1 from Infineon Technologies is a silicon Schottky diode in SOT343 package configured as a parallel pair, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW power dissipation, with typical forward voltage of 310 mV at 1 mA - used in high-speed switching and voltage clamping circuits in automotive infotainment power rails.
For engineers reviewing the BAS4007WE6327BTSA1 datasheet, BAS4007WE6327BTSA1 pinout, BAS4007WE6327BTSA1 application, or BAS4007WE6327BTSA1 equivalent, key selection criteria include low VF matching (≤20 mV), 3 pF capacitance at 0 V, 10 Ω differential forward resistance, 100 ps reverse recovery time, and AEC-Q101 qualification for under-hood signal conditioning.
Technical Context
This dual-diode configuration operates as a parallel pair - both anodes connected internally - enabling balanced current sharing and reduced thermal imbalance in clamping paths. Its Schottky barrier structure delivers fast switching (τrr ≤ 100 ps) and low forward conduction loss without minority-carrier storage delay.
The device is qualified to AEC-Q101 with Tj = 150 °C maximum junction temperature and RthJS = 125 K/W, supporting operation across –55 °C to +150 °C ambient while maintaining IR ≤ 1 µA at 30 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping in 3.3 V/5 V/12 V rail protection without breakdown |
| Forward Current (IF) | 120 mA DC - sufficient for logic-level signal routing and ESD transient shunting |
| Forward Voltage (VF) | 310 mV @ 1 mA - enables ultra-low-loss biasing in RF detector and mixer front-ends |
| Diode Capacitance (CT) | 3 pF @ 0 V, 1 MHz - preserves signal integrity in >100 MHz high-frequency switching nodes |
| Reverse Recovery Time (τrr) | 100 ps - ensures minimal switching distortion in pulse-width modulated timing circuits |
| Differential Forward Resistance (RF) | 10 Ω @ 10 kHz - stabilizes small-signal AC conduction in precision amplitude detection |
| Thermal Resistance (RthJS) | 125 K/W - allows sustained 120 mA operation at board-level soldering point ≤ 118 °C |
Pinout & Package
SOT343 package: 5-pin leadless surface-mount outline with exposed thermal pad; pin 1–3 assigned to cathode terminals, pin 4–5 to common anode connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, Pin 2, Pin 3 | Cathode (individual) | Three independent cathode outputs enable flexible routing of dual-diode parallel output paths |
| Pin 4, Pin 5 | Common Anode | Internally bonded anode node - requires single-point connection for uniform current injection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| Low VF Matching (ΔVF) | ≤20 mV between diodes - ensures balanced current division in parallel-pair configurations |
| ESD-Sensitive Handling | Class H2 per JESD22-A114 - mandates grounded workstation and ionized air handling during assembly |
| Pb-Free & RoHS Compliant | Meets EU Directive 2011/65/EU - compatible with lead-free reflow profiles up to 260 °C peak |
| High-Temp Junction Rating | 150 °C max Tj - supports continuous operation in under-dash electronics enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F40NXT5G | Single-diode SOD-523, 40 V/200 mA, 370 mV VF @ 10 mA, no VF matching spec | Lacks dual-diode integration - requires two devices and PCB layout duplication | Preferred only when space constraints prohibit SOT343 footprint and matching is non-critical |
| RB520S-40T1G | Single Schottky SOD-523, 40 V/200 mA, 390 mV VF @ 10 mA, unqualified for automotive | No AEC-Q101 certification - unsuitable for safety-critical vehicle subsystems | Select only for cost-sensitive consumer-grade USB or audio applications with no automotive compliance requirement |
Compared with NSR20F40NXT5G and RB520S-40T1G, BAS4007WE6327BTSA1 uniquely delivers integrated dual-diode matching, AEC-Q101 qualification, and SOT343 thermal performance - making it the sole choice for space-constrained, high-reliability automotive signal protection.

FAQ
Is BAS4007WE6327BTSA1 pin-compatible with BAS40-07W?
Yes - both use SOT343 package with identical pin 1–3 cathode / pin 4–5 common anode assignment. However, BAS4007WE6327BTSA1 adds AEC-Q101 qualification and tighter ΔVF matching (≤20 mV vs. unspecified for BAS40-07W), making it suitable for safety-critical automotive designs where the older variant is not approved.
What is the maximum allowable PCB copper area for thermal relief under 120 mA continuous load?
With RthJS = 125 K/W and TS limit of 118 °C, a minimum 25 mm² 2-oz copper pour connected to the exposed thermal pad is required to maintain junction temperature ≤150 °C at 70 °C ambient. Thermal vias (≥4×0.3 mm diameter) to inner ground layers further reduce effective RthJA.
Can BAS4007WE6327BTSA1 be used in 2.4 GHz Wi-Fi antenna switching?
No - although its 3 pF capacitance and 100 ps τrr support up to ~1 GHz operation, the SOT343 package parasitics and lack of specified RF S-parameters above 1 GHz make it unsuitable for 2.4 GHz antenna switch paths. For such applications, purpose-built GaAs or SOI RF switches are recommended.
Does BAS4007WE6327BTSA1 require special ESD handling during reflow soldering?
Yes - as an ESD-sensitive device (H2 class), it must be handled using grounded wrist straps, ionized air blowers, and static-dissipative trays before and after reflow. Post-reflow inspection must verify absence of micro-cracks or solder bridging, especially across the common-anode pins (4–5), which could compromise parallel-pair functionality.
