Product details
Overview
BAS40W-06-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 package, rated for 40 V peak repetitive reverse voltage, 200 mA forward current, and 5.0 ns reverse recovery time. It delivers low forward voltage drop (380 mV at 1.0 mA), ultra-fast switching, and integrated PN junction guard ring for ESD/transient protection-used in DC-DC converter output rectification and high-frequency signal clamping.
For engineers reviewing the BAS40W-06-7-F datasheet, BAS40W-06-7-F pinout, BAS40W-06-7-F application, or BAS40W-06-7-F equivalent, key selection criteria include its 40 V VRRM rating, sub-1 V VF at 40 mA, 5.0 ns trr, 5.0 pF CT at 0 V, and SOT323 thermal resistance of 625 °C/W-critical for compact power management and RF detector designs.
Technical Context
This Schottky diode employs a platinum-silicide (PtSi) or similar low-barrier metal-semiconductor junction to achieve fast switching and low forward conduction loss. Its guard ring structure isolates the active junction from surface contamination and edge breakdown, enhancing reliability under transient stress.
Designed for high-frequency operation up to ~1 GHz, it exhibits minimal stored charge and negligible minority-carrier storage-enabling clean turn-off in flyback snubbers and RF envelope detection. The SOT323 package supports reflow soldering per J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage before avalanche; defines safe operating range in clamp and rectifier circuits |
| VF @ 1.0 mA | 380 mV - Low conduction loss at light load; reduces standby power in battery-powered signal paths |
| trr | 5.0 ns - Ultra-fast recovery enables use in >100 MHz switching applications without tail current issues |
| CT @ 0 V | 5.0 pF - Minimal junction capacitance preserves signal integrity in RF detector and mixer bias networks |
| RθJA | 625 °C/W - Thermal resistance limits power dissipation to 200 mW at TA = 25°C on FR4 board with standard pad layout |
| IR @ 30 V | 200 nA - Low leakage maintains accuracy in precision sample-and-hold and sensor interface circuits |
Pinout & Package
Package: SOT323 - ultra-small plastic surface-mount package (2.0 × 2.225 × 0.9 mm), lead-free, RoHS-compliant, with matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to lower-potential node in rectifier/clamp; polarity marked by cathode band on package top view |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Connected to higher-potential node; carries full reverse voltage during off-state; guards against ESD via integrated PN ring |
| Collector/Case (Pin 3) | Thermal and mechanical anchor | Non-electrical; internal die attach paddle; improves heat spreading but not electrically connected to die |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at low current | 380 mV @ 1.0 mA enables efficient biasing in low-power analog front-ends without significant voltage offset |
| Guard ring protection | Integrated PN junction ring suppresses surface leakage and improves ESD robustness to >8 kV HBM (per design intent) |
| Ultra-small footprint | SOT323 (2.0 × 2.225 mm) saves PCB area in space-constrained IoT sensor nodes and wearable power rails |
| Fast trr with low Qrr | 5.0 ns recovery with near-zero stored charge minimizes switching loss in 1–10 MHz DC-DC synchronous rectifiers |
Applications
| DC-DC Converter Output Rectification | RF Signal Detection & Clamping |
|---|---|

Use Value: Guard ring structure enables reliable 8 kV HBM protection without external TVS; SOT323 fits tight trace routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0540T1G (ON Semiconductor) | Same 40 V VRRM, but SOD-123 package (larger); VF = 450 mV @ 1.0 mA; trr = 10 ns | Higher thermal mass suits higher average current (500 mA IF), but slower switching limits RF use | Select when board space allows and average current exceeds 200 mA |
| NSR0240HT1G (onsemi) | SOT-23 package; VF = 370 mV @ 1.0 mA; trr = 4.5 ns; CT = 4.5 pF; same 40 V rating | Nearly identical RF performance, but SOT-23 has higher RθJA (700 °C/W) and larger footprint | Prefer for marginally faster trr where thermal derating permits |
Compared with MBR0540T1G and NSR0240HT1G, BAS40W-06-7-F offers the smallest footprint (SOT323), lowest thermal resistance among ultra-small Schottkys, and optimized guard ring for ESD-critical I/O-making it ideal for miniaturized, high-frequency, and robust interface designs.

FAQ
What is the maximum junction temperature for BAS40W-06-7-F?
The device has an operating junction temperature range of –55 °C to +125 °C. At ambient temperatures above 25 °C, power dissipation must be derated linearly per Fig. 4 in the datasheet, reaching zero at +125 °C ambient due to its 625 °C/W RθJA on FR4 board.
Is BAS40W-06-7-F suitable for automotive applications?
The standard BAS40W-06-7-F is not AEC-Q200 qualified. However, Diodes offers the automotive-grade variant BAS40WQ under a separate datasheet, which meets AEC-Q200 requirements and is qualified for under-hood and infotainment systems.
How does the guard ring improve reliability?
The integrated PN junction guard ring surrounds the active Schottky junction to prevent premature edge breakdown under high electric field stress, reducing surface leakage and improving robustness against ESD events and humidity-induced degradation-verified in Diodes' qualification testing per JESD22-A114.
Can BAS40W-06-7-F replace BAS40W-04-7-F or BAS40W-05-7-F in a design?
Yes-BAS40W-04, -05, and -06 share identical electrical specifications and SOT323 packaging. Differences are only in date-code marking and internal wafer lot traceability; all three are functionally interchangeable in circuit design and layout.
