Product details
Overview
BAS40W-06-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 package, rated for 40 V peak repetitive reverse voltage and 200 mA forward current, with low 380 mV forward voltage at 1 mA and ultra-fast 5.0 ns reverse recovery time. It serves as a high-efficiency rectifier or signal clamping device in space-constrained DC-DC converter feedback paths, RF detector circuits, and low-voltage logic protection networks.
For engineers reviewing the BAS40W-06-7 datasheet, BAS40W-06-7 pinout, BAS40W-06-7 application, or BAS40W-06-7 equivalent, key selection criteria include its 40 V VRRM, 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 - all critical for high-frequency switching and low-power signal integrity.
Technical Context
This Schottky diode uses a platinum-silicide (PtSi) or similar low-barrier metal-semiconductor junction to achieve fast switching and low forward conduction loss. Its guard-ringed PN junction structure provides ESD robustness up to ±2 kV HBM without compromising switching speed.
The device operates across –55 °C to +125 °C and derates linearly above 25 °C ambient, delivering 200 mW power dissipation at room temperature and maintaining <200 nA leakage at 30 V reverse bias - enabling stable performance in battery-powered sensor nodes and portable USB interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking capability without avalanche breakdown |
| VF @ 1 mA | 380 mV - Enables efficient signal-level clamping with minimal voltage offset |
| trr | 5.0 ns - Supports >100 MHz switching in RF detector and sampling circuits |
| CT @ 0 V | 5.0 pF - Low junction capacitance preserves bandwidth in high-speed signal routing |
| IR @ 30 V | 200 nA - Ensures negligible leakage in precision analog front-ends and standby power rails |
| RθJA | 625 °C/W - Requires minimal PCB copper area for thermal management in compact layouts |
| PD | 200 mW - Limits continuous power handling but suits intermittent pulse applications |
Pinout & Package
Package: SOT323 - ultra-small plastic surface-mount package (2.0 × 2.2 mm footprint, 0.9 mm height), lead-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to lower-potential node in rectification; polarity-marked side on top view |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Internally tied to package tab (Pin 3); used for heat sinking and ground reference |
| Tab / Exposed Pad (Pin 3) | Thermal and electrical connection to cathode | Must be soldered to PCB copper pour for thermal relief and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 380 mV at 1 mA enables sub-1 V logic-level clamping without loading source |
| Ultra-fast switching | 5.0 ns trr supports clean edge preservation in 50–100 MHz RF envelope detection |
| PN junction guard ring | Provides ±2 kV HBM ESD protection while maintaining Schottky conduction characteristics |
| SOT323 footprint | 2.0 × 2.2 mm outline allows placement in dense layout areas where SOIC or SOD-123 are too large |
Applications
| USB Port Protection | RF Signal Detector |
|---|---|
Use Scenario: Protecting downstream USB 2.0 data lines (D+/D−) from ESD transients during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between data line and ground, leveraging low VF and guard ring for IEC 61000-4-2 compliance. Use Value: 200 nA leakage at 30 V prevents signal degradation; 5 pF CT avoids high-frequency attenuation on 480 Mbps signals. | Use Scenario: Demodulating AM-modulated RF carrier in 868 MHz ISM-band wireless sensor transmitters. IC Role / Device Role / Timing Role: Zero-bias Schottky detector diode in envelope extraction circuit with parallel RC load. Use Value: 5.0 ns trr ensures faithful reproduction of modulation envelope up to ~100 MHz; low CT minimizes detuning of matching network. |
| DC-DC Feedback Path | Low-Voltage Logic Clamp |
Use Scenario: Providing precise voltage reference feedback in 3.3 V synchronous buck converter output stage. IC Role / Device Role / Timing Role: Reverse-biased clamp across optocoupler LED to limit feedback loop overshoot during load transients. Use Value: 40 V VRRM accommodates transient spikes beyond nominal 3.3 V rail; 380 mV VF ensures tight regulation window. | Use Scenario: Preventing overvoltage damage to 1.8 V GPIO pins on microcontrollers interfacing with 3.3 V peripherals. IC Role / Device Role / Timing Role: Anode-to-GPIO, cathode-to-3.3 V rail - conducting only when GPIO exceeds 3.3 V + VF. Use Value: Sub-1 V forward drop enables safe clamping at 3.3 V without violating 1.8 V absolute maximum rating; SOT323 fits near BGA packages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | 30 V VRRM, 360 mV VF @ 1 mA, same SOT-23 package | Limited to ≤30 V systems; slightly lower VF but reduced reverse blocking margin | Select when system reverse voltage stays below 30 V and lowest possible forward loss is prioritized |
| RB520S-40T1G | 40 V VRRM, 450 mV VF @ 1 mA, SOD-523 package (smaller than SOT323) | Higher VF increases conduction loss; smaller footprint may complicate rework | Choose for ultra-dense layouts where 0.6 × 0.3 mm SOD-523 is mandatory and 70 mV VF penalty is acceptable |
Compared with NSR0230HT1G and RB520S-40T1G, BAS40W-06-7 uniquely balances 40 V blocking, 380 mV low-current VF, and SOT323 manufacturability - making it optimal for mixed-signal interfaces requiring both robustness and signal fidelity.

FAQ
What is the maximum junction temperature for BAS40W-06-7?
The device has an operating junction temperature range of –55 °C to +125 °C. At 25 °C ambient, its 200 mW power dissipation and 625 °C/W thermal resistance allow a theoretical ΔT of 125 °C - aligning precisely with the upper limit. Derating begins linearly above 25 °C per Figure 4 in the datasheet.
Does BAS40W-06-7 have integrated ESD protection?
Yes - it features a PN junction guard ring structure that provides inherent ESD robustness, rated to ±2 kV per Human Body Model (HBM). This is confirmed in the "Features" section and supported by test conditions in the datasheet's Absolute Maximum Ratings table.
Can BAS40W-06-7 be used in zero-bias RF detector applications?
Yes - its 5.0 pF junction capacitance at 0 V and 5.0 ns reverse recovery time make it suitable for zero-bias envelope detection at frequencies up to 100 MHz. The low VF ensures minimal threshold voltage, preserving weak-signal sensitivity in crystal radio or ISM-band receiver front-ends.
Is BAS40W-06-7 automotive-qualified?
No - the standard BAS40W-06-7 is not AEC-Q200 qualified. Diodes offers the automotive-grade variant BAS40WQ under a separate datasheet, which includes extended temperature screening, enhanced reliability testing, and PPAP documentation support for automotive applications.
