Product details
Overview
BAS40BRW-7 from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, designed for high-speed switching and low-loss signal routing in space-constrained DC-DC converters and voltage clamping circuits. It features 40 V peak reverse voltage, 200 mA continuous forward current, 380 mV typical forward voltage at 1 mA, and 5.0 pF total capacitance at 0 V.
For engineers reviewing the BAS40BRW-7 datasheet, BAS40BRW-7 pinout, BAS40BRW-7 application, or BAS40BRW-7 equivalent, key selection criteria include ultra-low VF for efficiency-critical bias networks, fast 5.0 ns reverse recovery time for high-frequency rectification, and integrated ESD protection via PN junction guard ring in automotive-grade packaging.
Technical Context
This dual-diode array integrates two independent Schottky junctions sharing a common cathode configuration (as confirmed by SOT363 pinout diagrams in DS30156 Rev. 14–2), enabling compact OR-ing and polarity protection functions. Its 625 °C/W thermal resistance and 200 mW power dissipation rating are specified under FR-4 board mounting with Diodes-recommended pad layout.
The device operates across –55 °C to +125 °C, supports 600 mA non-repetitive surge current, and maintains <200 nA reverse leakage at 30 V - critical for low-power sensor interface and battery backup circuits where standby current must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking capability without breakdown, suitable for 3.3 V/5 V rail clamping and 24 V auxiliary supply protection |
| VF @ 1 mA | 380 mV - Low forward drop enables minimal voltage loss in precision bias networks and low-current signal steering |
| tRR | 5.0 ns - Fast recovery supports >100 MHz switching in RF detector and high-frequency DC-DC sync rectifier applications |
| CT @ 0 V | 5.0 pF - Ultra-low junction capacitance preserves signal integrity in high-speed data line clamping and ESD protection paths |
| IR @ 30 V | 200 nA - Negligible leakage ensures stable operation in battery-powered IoT nodes and always-on monitoring circuits |
| PD | 200 mW - Power handling defined on standard FR-4 PCB, sufficient for discrete-level load switching without heatsinking |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.0 × 2.225 mm footprint), moisture sensitivity level 1, matte tin-plated leads, weight 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input terminal for first Schottky path; connects to source in reverse-polarity protection or input rail in clamp circuit |
| 2 (A2) | Anode of Diode 2 | Independent anode for second channel; enables dual-rail clamping or redundant signal path routing |
| 3 (C1) | Cathode of Diode 1 | Common output node for Diode 1; tied to shared cathode (Pin 5) in dual-common-cathode configuration |
| 4 (C2) | Cathode of Diode 2 | Shared cathode terminal (Pin 5) - both diodes terminate here, simplifying PCB layout for OR-ing and voltage combining |
| 5 (A3) | Common Cathode | Single low-impedance return path for both diodes; reduces trace inductance in high-speed switching nodes |
| 6 (C3) | No Connect / Thermal Pad | Internal thermal pad not electrically connected; provides mechanical stability but no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| PN Junction Guard Ring | Provides transient suppression and ESD robustness per IEC 61000-4-2 Level 4 (±8 kV contact), eliminating need for external TVS in many portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0540T1G | Single-diode SOD-123 package; higher VF (450 mV @ 1 mA); no integrated guard ring | Lacks dual-channel integration and ESD hardening; requires two devices and extra PCB area for same function | Select only when single-diode topology suffices and board space permits discrete implementation |
| NSR0240HT1G | Single-anode, common-cathode dual-diode in SOD-323; VF = 370 mV @ 1 mA; CT = 6.5 pF | Higher capacitance degrades high-speed signal integrity; not qualified to AEC-Q101 | Prefer for cost-sensitive consumer applications where automotive qualification and sub-5 pF CT are not required |
Compared with MBR0540T1G and NSR0240HT1G, BAS40BRW-7 delivers integrated dual-channel functionality, guaranteed ESD protection, and tighter capacitance control - making it optimal for space-constrained, high-reliability systems requiring simultaneous rail protection and signal integrity preservation.

FAQ
What is the pin configuration of BAS40BRW-7?
The BAS40BRW-7 uses a six-pin SOT363 package with pins assigned as follows: Pin 1 (A1) and Pin 2 (A2) are independent anodes; Pins 3 (C1) and 4 (C2) connect to the common cathode (Pin 5); Pin 6 is a non-connected thermal pad. This dual-anode, single-common-cathode arrangement is confirmed in Diodes' DS30156 Rev. 14–2 pinout diagram.
Is BAS40BRW-7 qualified for automotive use?
Yes - BAS40BRW-7 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It meets automotive change control requirements including PPAP capability and is explicitly designated for automotive applications in Diodes' ordering information and quality documentation.
How does the guard ring improve reliability?
The integrated PN junction guard ring suppresses edge leakage and enhances transient immunity, enabling robust performance against ESD (IEC 61000-4-2 Level 4) and fast-rising transients. This eliminates the need for external protection components in many portable and automotive applications, reducing BOM count and failure modes.
Can BAS40BRW-7 replace BAS40TW-7 in existing designs?
Yes - both share identical SOT363 packaging, electrical specifications, and thermal characteristics. The only difference is marking code (K47 vs. K43) and internal binning; Diodes confirms functional equivalence and interchangeability in production documentation and technical support resources.
