Product details
Overview
BAS140WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode optimized for high-speed switching, voltage clamping, and RF signal mixing in compact consumer and industrial electronics. It features 40 V reverse voltage rating, 120 mA forward current, 250 mW power dissipation (at TS ≤ 113 °C), 3 pF typical junction capacitance at 0 V, and 10 Ω typical differential forward resistance at 10 kHz - enabling low-loss signal routing in portable audio and sensor interface circuits.
For engineers reviewing the BAS140WE6327HTSA1 datasheet, BAS140WE6327HTSA1 pinout, BAS140WE6327HTSA1 application, or BAS140WE6327HTSA1 equivalent, key selection criteria include its SOD323 package footprint, AEC-Q101 qualification for automotive-grade reliability, low forward voltage (310 mV typ. at 10 mA), fast recovery time (<100 ps), and ESD-sensitive handling requirements.
Technical Context
This Schottky diode operates with zero minority-carrier storage, delivering sub-100 ps reverse recovery time and minimal switching loss. Its low 3 pF junction capacitance and 10 Ω dynamic resistance support stable RF performance up to UHF frequencies in detector and mixer stages.
The device is rated for continuous operation from –55 °C to +150 °C, with thermal resistance from junction to soldering point ≤150 K/W. Its AEC-Q101 qualification confirms suitability for automotive infotainment and body control modules requiring robust transient immunity and long-term bias stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping and protection in 24 V automotive and 3.3/5 V logic rail applications without breakdown. |
| Forward Current (IF) | 120 mA DC - sufficient for signal-level rectification and level shifting in sensor front-ends and I/O protection networks. |
| Junction Capacitance (CT) | 3 pF typ. at 0 V, 1 MHz - enables minimal signal distortion in 433 MHz ISM band receivers and RF envelope detectors. |
| Forward Voltage (VF) | 310 mV typ. at 10 mA - reduces conduction loss and self-heating in battery-powered signal path conditioning. |
| Differential Forward Resistance (RF) | 10 Ω typ. at 10 kHz - ensures predictable small-signal impedance matching in analog switch and clamp circuits. |
| Reverse Recovery Time (τrr) | <100 ps - eliminates tail current and enables clean edge transitions in high-frequency sampling and pulse shaping. |
| Junction Temperature (Tj) | 150 °C max - allows operation in thermally constrained PCB layouts near power regulators or processors. |
Pinout & Package
Package: SOD323 - surface-mount plastic case, 1.3 mm × 0.85 mm footprint, 0.95 mm height, cathode marked by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry terminal under forward bias | Connected to lower-potential node in clamping or rectifier configuration; requires low-inductance trace routing for RF integrity. |
| Cathode (K) | Current exit terminal under forward bias; marked by band | Typically tied to reference rail (e.g., VCC or ground) in voltage clamp or detector topologies; defines polarity-sensitive placement. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment power management and CAN bus ESD protection circuits. |
| Low VF matching (ΔVF ≤ 20 mV) | Enables consistent performance across dual/multi-diode arrays in precision detector or balanced mixer designs. |
| Pb-free, RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-020 reflow profile requirements for lead-free assembly. |
| ESD-sensitive handling | Requires IEC 61340-5-1 compliant workstation controls (e.g., grounded mats, wrist straps) during PCB assembly. |
Applications
| Automotive Infotainment Power Clamping | Portable Audio Signal Detection |
|---|---|
Use Scenario: Clamping transient spikes on 12 V supply rails feeding AM/FM tuner ICs and DSP audio processors. IC Role / Device Role: Fast-switching Schottky clamp diode placed between rail and ground to shunt overvoltage events. Use Value: 40 V VR rating and <100 ps τrr prevent latch-up in downstream ICs while minimizing leakage-induced battery drain. |
Use Scenario: Envelope detection of 2.4 GHz Bluetooth audio packets in wireless earbud receiver front-ends. IC Role / Device Role: RF signal demodulator using nonlinear junction characteristics for amplitude extraction. Use Value: 3 pF CT and 10 Ω RF enable accurate low-distortion detection without external tuning components. |
| Industrial Sensor Level Shifting | USB-C ESD Protection Interface |
Use Scenario: Translating 0–3.3 V analog outputs from MEMS pressure sensors to 5 V microcontroller ADC inputs. IC Role / Device Role: Passive level translator using forward-biased Schottky drop to offset signal baseline. Use Value: 310 mV VF at 10 mA provides predictable, temperature-stable offset with no active bias circuitry required. |
Use Scenario: Secondary ESD protection on USB-C CC and SBU lines adjacent to primary TVS arrays. IC Role / Device Role: Low-capacitance steering diode that activates before main TVS to limit initial surge energy. Use Value: 1 µA IR at 30 V ensures negligible standby current while 40 V VR aligns with USB-C VBUS tolerance margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DWY | 0.85 pF CT (lower), 150 mA IF, SOT323 package - larger footprint, higher thermal resistance (≤375 K/W). | Preferred for ultra-low-capacitance RF detector use but less suitable for space-constrained automotive PCBs. | Select when sub-1 pF capacitance outweighs board area constraints and thermal derating is manageable. |
| NSR0230P2T5G | 30 V VR (lower), 200 mA IF, same SOD323 package - not AEC-Q101 qualified, higher VF (370 mV typ. at 10 mA). | Acceptable for cost-sensitive consumer wearables but excluded from automotive BOMs requiring qualification evidence. | Choose only for non-automotive, non-safety-critical designs where 40 V margin is unnecessary. |
Compared with SBAT54DWY and NSR0230P2T5G, BAS140WE6327HTSA1 uniquely balances AEC-Q101 compliance, 40 V robustness, and SOD323 miniaturization - making it the default choice for automotive signal-path protection where qualification, size, and voltage margin are jointly critical.

FAQ
Is BAS140WE6327HTSA1 AEC-Q101 qualified?
Yes, BAS140WE6327HTSA1 is explicitly qualified per AEC-Q101 Rev D for stress testing including HTSL, TCT, and ESD. This qualification is documented in Infineon's official product change notice dated January 2013 and applies to all SOD323-packaged BAS140W variants bearing the "HTSA1" suffix.
What is the maximum allowable soldering temperature for BAS140WE6327HTSA1?
The device complies with JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for 10 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be limited to 60–150 seconds per IPC/JEDEC standards.
Can BAS140WE6327HTSA1 replace BAS40-06W in existing designs?
No - BAS40-06W uses SOT23 packaging with different thermal resistance (≤375 K/W vs. ≤150 K/W) and lower power derating (TS ≤ 56 °C). Substituting BAS140WE6327HTSA1 requires PCB pad redesign and thermal validation due to SOD323's smaller footprint and superior thermal performance.
Does BAS140WE6327HTSA1 have a specified reverse recovery charge (Qrr)?
No - Qrr is not characterized or guaranteed for this Schottky diode. Its sub-100 ps reverse recovery time reflects majority-carrier conduction behavior, eliminating stored charge; design reliance on Qrr-based snubber calculations is therefore unnecessary and unsupported.
