Product details
Overview
BAS40-06WF from Nexperia is a general-purpose dual Schottky diode in SOT323 (SC-70) package, featuring common-anode configuration for ultra-high-speed switching and voltage clamping. It delivers 40 V reverse voltage rating, 120 mA forward current capability, 380 mV forward voltage at 1 mA, 5 pF diode capacitance at 0 V, and 1 µA reverse leakage at 30 V - deployed in RF detector front-ends and logic-level signal clamping circuits.
For engineers reviewing the BAS40-06WF datasheet, BAS40-06WF pinout, BAS40-06WF application, or BAS40-06WF equivalent, key selection criteria include common-anode dual-diode topology, low VF/low Cd trade-off for high-frequency signal integrity, thermal resistance of 625 K/W on FR4, and non-automotive qualification status per revision history.
Technical Context
This dual Schottky diode integrates two independent junctions sharing a single anode terminal, enabling compact bidirectional clamping or dual-path rectification in space-constrained layouts. Its low 5 pF capacitance and sub-400 mV forward drop at low current support operation up to UHF frequencies without significant signal distortion.
The device operates with junction temperatures up to 150 °C and ambient range from –65 °C to +150 °C, while its 200 mA non-repetitive peak forward current supports transient surge handling. Thermal resistance of 625 K/W reflects standard single-sided FR4 mounting - not optimized for power dissipation but suitable for signal-level protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - sets maximum clamping threshold before breakdown in voltage-limiting applications |
| Forward Voltage (VF) | 380 mV @ 1 mA - enables low-loss signal steering in low-current logic interfaces |
| Reverse Leakage (IR) | 1 µA @ 30 V - ensures minimal DC loading in high-impedance bias networks |
| Diode Capacitance (Cd) | 5 pF @ 0 V, 1 MHz - preserves bandwidth in RF detector and mixer IF stages |
| Forward Current (IF) | 120 mA continuous - supports moderate-duty switching in level-shifting and clamp circuits |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines temperature rise per watt on standard FR4 PCB, limiting sustained power handling |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, designed for reflow soldering with standardized footprint per Figure 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Provides dedicated cathode path for first Schottky junction; routed separately for asymmetric clamping |
| 2 | K2 (cathode of diode 2) | Independent cathode node for second junction; enables dual-rail or differential clamping |
| 3 | A1/A2 (common anode) | Shared anode connection - simplifies PCB layout for bidirectional protection or dual-input OR-ing |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Enabled by low stored charge and Schottky barrier - supports >100 MHz signal edge rates |
| Low leakage current | 1 µA max at 30 V reverse bias - maintains accuracy in precision reference and sensor bias paths |
| High breakdown voltage | 40 V VR rating - accommodates 3.3 V/5 V/12 V rail clamping with margin against transients |
| Low capacitance | 5 pF typical - minimizes loading on RF detectors, mixers, and high-speed digital inputs |
Applications
| RF Detector Clamping | Logic-Level Signal Clamping |
|---|---|
Use Scenario: Protecting input stage of RF logarithmic detector ICs from overvoltage during antenna coupling surges. IC Role / Device Role / Timing Role: Dual-cathode Schottky clamp limiting positive/negative excursions to ±0.4 V around common-anode reference. Use Value: 5 pF capacitance avoids detuning detector LC tank; 380 mV VF ensures clamping engages before CMOS input damage threshold. |
Use Scenario: Level-shifting 1.8 V GPIO signals to 3.3 V domain while preventing back-drive into low-voltage supply. IC Role / Device Role / Timing Role: Common-anode dual diode providing bidirectional clamping between rails and I/O pins. Use Value: Low VF and fast recovery preserve signal rise/fall times; 120 mA IF rating handles ESD pulse energy without degradation. |
| Digital Input Protection | High-Speed Comparator Input Clamp |
Use Scenario: Safeguarding microcontroller input pins exposed to industrial fieldbus voltages up to ±24 V. IC Role / Device Role / Timing Role: Cathodes tied to protected pin and ground; common anode connected to 3.3 V rail for active clamping. Use Value: 40 V VR withstands worst-case transients; 1 µA IR prevents false triggering in high-Z sampling windows. |
Use Scenario: Preventing comparator input saturation during fast-rising analog pulses in time-of-flight measurement circuits. IC Role / Device Role / Timing Role: Dual diode clamps comparator inputs to rail voltages, limiting differential swing to safe range. Use Value: Matched VF across both junctions ensures symmetrical clamping thresholds; 625 K/W Rth(j-a) avoids thermal drift during burst-mode operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Lower VF (270 mV @ 1 mA), higher IR (5 µA @ 30 V), same SOT-323 package | Better efficiency in low-voltage biasing; less suitable for high-impedance sensing due to higher leakage | Select when forward loss dominates design priority and leakage tolerance >5 µA |
| Diodes Incorporated SD103AW-7-F | Higher VF (450 mV @ 1 mA), lower Cd (3.5 pF), automotive-qualified (-Q version available) | Superior RF isolation at cost of higher conduction loss; qualified for under-hood environments | Select when EMI suppression or AEC-Q200 compliance is required over low-VF performance |
Compared with BAS40-06WF, NSR0230HT1G trades leakage for lower VF in battery-sensitive bias networks, while SD103AW-7-F sacrifices conduction efficiency for tighter RF control and automotive qualification - making BAS40-06WF the balanced choice for industrial signal integrity where leakage, capacitance, and cost must co-optimize.

FAQ
Is BAS40-06WF qualified for automotive applications?
No. Per the October 2022 revision history, BAS40-06WF was explicitly changed to non-automotive qualification status. Nexperia offers separate -Q qualified alternatives (e.g., BAS40-06W-Q) for automotive use. This part lacks AEC-Q200 testing and is not warranted for under-hood or safety-critical systems.
What is the maximum allowable power dissipation for BAS40-06WF on a standard PCB?
Based on Rth(j-a) = 625 K/W and Tj(max) = 150 °C with Tamb = 25 °C, the theoretical max continuous power is (150 − 25) / 625 = 0.2 W. However, the 120 mA absolute maximum forward current limits practical dissipation to ~48 mW at 400 mV VF - well below thermal limit, confirming it is signal-optimized, not power-rated.
Can BAS40-06WF be used in reverse-series configuration for bipolar clamping?
Yes. With independent cathodes (pins 1 and 2) and shared anode (pin 3), connecting pin 3 to a reference voltage (e.g., 3.3 V) and routing pins 1 and 2 to separate signal lines enables simultaneous positive and negative clamping - commonly applied in differential receiver protection and analog front-end limiting.
Does the "WF" suffix indicate a different specification than "W"?
Per Nexperia's ordering information and marking table, "BAS40-06WF" is a valid orderable variant with identical electrical and mechanical specifications to BAS40-06W. The "F" denotes tape-and-reel packaging per standard Nexperia coding - no parameter or performance difference exists between the two suffixes.
