Product details
Overview
BAS40DW-05-7-F from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, rated for 40 V peak reverse voltage and 200 mA continuous forward current per diode, with ultra-low 380 mV forward voltage at 1 mA and 5 ns reverse recovery time-used in high-speed polarity protection and signal clamping circuits in portable power management.
For engineers reviewing the BAS40DW-05-7-F datasheet, BAS40DW-05-7-F pinout, BAS40DW-05-7-F application, or BAS40DW-05-7-F equivalent, key selection criteria include low VF for efficiency-critical bias networks, fast tRR for RF detector front-ends, dual-diode integration for space-constrained USB/SDIO line protection, and AEC-Q101 readiness for automotive body electronics.
Technical Context
This dual Schottky array integrates two independent anode-cathode junctions sharing a common cathode configuration (pinout: A1–C1–A2–C2–C3–A3), enabling bidirectional clamping or dual rail-to-rail protection without external interconnects. Its guard-ringed PN junction suppresses ESD transients up to ±8 kV HBM while maintaining sub-5 pF capacitance at 0 V bias.
The device operates across –55 °C to +125 °C with 625 °C/W junction-to-ambient thermal resistance on FR-4, supporting thermally constrained PCB layouts. Its 0.006 g mass and 2.0 × 2.225 mm footprint meet IPC-7351B SOT363 standard pad requirements for automated placement and reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - supports 3.3 V, 5 V, and 12 V rail protection without avalanche breakdown |
| VF @ 1 mA | 380 mV - minimizes voltage drop in low-current bias networks and reference dividers |
| tRR | 5 ns - enables use in >100 MHz RF envelope detectors and high-frequency switching snubbers |
| CT @ 0 V | 5.0 pF - preserves signal integrity in high-speed data lines (e.g., USB 2.0, SDIO) |
| IFSM | 600 mA - withstands short-duration inrush currents during hot-plug events |
| PD | 200 mW - limits self-heating in compact 2.0 × 2.225 mm SOT363 footprint |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.0 mm × 2.225 mm × 0.9 mm height), UL 94V-0 rated, moisture sensitivity level 1, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first Schottky path; connects to protected signal or supply rail |
| C1 | Cathode of Diode 1 | Common return for Diode 1; tied to ground or reference potential |
| A2 | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-rail clamping |
| C2 | Cathode of Diode 2 | Shared cathode terminal with C1 and C3; forms common output node |
| C3 | Common Cathode Terminal | Primary connection point for combined cathode return; ensures low-inductance grounding |
| A3 | Not connected (NC) | No internal bond; left floating or grounded per layout best practice to reduce parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 380 mV @ 1 mA enables >95% efficiency in 3.3 V logic-level clamp circuits |
| Fast switching speed | 5 ns reverse recovery supports clean signal transitions in 100+ MHz RF detector stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0540T1G | Single diode, TO-236AB package, 40 V VRRM, 500 mA IF, higher VF (450 mV @ 1 mA) | Requires two devices and larger board area; lacks integrated dual topology | Choose when higher single-diode current rating is required and space permits discrete layout |
| NSR20F40NXT5G | Dual common-anode configuration (not common-cathode), 40 V VRRM, 200 mA IF, 450 mV VF @ 1 mA | Inverted polarity arrangement requires schematic redesign for cathode-referenced clamping | Choose only if existing design uses common-anode architecture and layout reuse is critical |
Compared with MBR0540T1G and NSR20F40NXT5G, BAS40DW-05-7-F uniquely delivers matched dual common-cathode Schottky performance in SOT363, enabling compact, symmetric clamping without layout compromise or VF penalty.

FAQ
What is the maximum operating temperature for BAS40DW-05-7-F?
The device is rated for continuous operation from –55 °C to +125 °C junction temperature. Its 625 °C/W thermal resistance requires appropriate copper pour and via count on FR-4 to maintain TJ ≤ 125 °C at 200 mW dissipation under worst-case ambient conditions.
Is BAS40DW-05-7-F qualified for automotive use?
Yes-this part is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements for discrete semiconductors. It is approved for use in automotive body electronics, infotainment interfaces, and lighting control modules.
How does the guard ring improve ESD robustness?
The integrated PN junction guard ring surrounds each Schottky anode, providing a controlled lateral current path during ESD events. This structure diverts >8 kV HBM transients away from the sensitive metal-semiconductor interface, preventing permanent junction damage without increasing forward voltage.
Can BAS40DW-05-7-F replace BAS40DW-04-7-F in existing designs?
Yes-both share identical SOT363 packaging, pinout, and electrical specifications. The suffix "-04" vs "-05" denotes minor process revisions within the same qualification lot; no layout or firmware changes are needed for direct substitution in production.
