Product details
Overview
BAS40-05/DG/B3R from Nexperia is a dual-channel Schottky barrier diode in SOT-323 package, rated at 40 V reverse voltage, 200 mA average forward current per anode, and 0.45 V typical forward voltage at 10 mA. It serves as high-speed switching and clamping diode in portable DC-DC converter feedback paths.
For engineers reviewing the BAS40-05/DG/B3R datasheet, BAS40-05/DG/B3R pinout, BAS40-05/DG/B3R application, or BAS40-05/DG/B3R equivalent, key selection criteria include low VF for efficiency-critical bias networks, dual-anode configuration for synchronous rectifier auxiliary sensing, and SOT-323 footprint compatibility with space-constrained PMIC layouts.
Technical Context
This dual Schottky diode integrates two independent anode terminals sharing a common cathode, enabling bidirectional clamping or dual-path current steering. Its epitaxial silicon construction delivers 1 ns reverse recovery time and 1.5 pF junction capacitance at 0 V, supporting >100 MHz switching in RF detector and fast transient suppression circuits.
The device operates across −65 °C to +150 °C ambient range with 250 mW total power dissipation rating. Thermal resistance from junction-to-ambient is 500 K/W in standard FR-4 PCB layout, requiring minimal copper pour for thermal management in battery-powered applications.
Key Specifications

|---|---|
| VR (Reverse Voltage) | 40 V - supports input rails up to 36 V nominal without breakdown in clamp or flyback snubber roles |
| IF(AV) per Anode | 200 mA - enables use in low-power logic-level signal routing and LED bias control |
| VF @ 10 mA | 0.45 V typical - reduces conduction loss by ≥30% vs. standard silicon diodes in 3.3 V domain bias networks |
| trr | 1 ns - allows clean edge transition handling in 100+ MHz clock line clamping |
| CJ @ 0 V | 1.5 pF - minimizes capacitive loading on high-impedance sensor output nodes |
| Tj max | +150 °C - qualified for under-hood automotive modules and industrial motor drive gate driver aux supplies |

Use Scenario: Bidirectional VBUS/ID pin protection in OTG-capable USB ports. IC Role / Device Role / Timing Role: Dual-anode Schottky clamps both data line and power line transients to 3.3 V rail while blocking reverse current. Use Value: Prevents latch-up in USB transceivers during hot-plug events without adding series resistance that degrades signal integrity. | Use Scenario: Clamp error amplifier output in buck converter feedback loop during light-load discontinuous conduction mode. IC Role / Device Role / Timing Role: Fast-recovery Schottky limits op-amp swing to prevent saturation and reduce recovery delay. Use Value: Improves load transient response by 15–20% compared to RC-based clamping due to sub-nanosecond turn-on. |
| Automotive Door Module Sensing | RF Detector Bias Network |
Use Scenario: Voltage translation and overvoltage protection for LIN bus wake-up input pins. IC Role / Device Role / Timing Role: Dual-anode configuration routes 12 V battery spikes to separate 5 V and 3.3 V LDO inputs via independent clamping paths. Use Value: Enables single-component protection of mixed-voltage microcontroller I/O banks without cross-talk between supply domains. | Use Scenario: DC restoration and bias feed in 2.4 GHz Wi-Fi front-end envelope detectors. IC Role / Device Role / Timing Role: Low-CJ Schottky provides minimal phase distortion while delivering stable DC offset to baseband amplifiers. Use Value: Maintains <−45 dBc harmonic distortion at 20 dBm input, meeting IEEE 802.11n spectral mask requirements. |
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 NSR20F40NXT5G | Single-anode, single-cathode SOD-523 package; 0.42 V VF @ 10 mA; no dual-anode topology | Requires two devices for dual-path clamping; higher board area and solder joint count | Select when only one clamping path is needed and ultra-low VF is prioritized over integration |
| Vishay SDM100S30 | Single-channel SOT-23; 30 V VR; 100 mA IF(AV); 0.52 V VF @ 10 mA | Limited to lower voltage rails and reduced current capacity; not AEC-Q101 qualified | Use in cost-sensitive consumer IoT where automotive qualification and dual functionality are unnecessary |
Compared with NSR20F40NXT5G and SDM100S30, BAS40-05/DG/B3R uniquely delivers dual-anode integration in automotive-qualified SOT-323, enabling compact, robust clamping for multi-rail systems without compromising speed or thermal performance.

FAQ
What is the maximum continuous reverse voltage rating for BAS40-05/DG/B3R?
The device is rated for 40 V continuous reverse voltage (VR), verified per Nexperia's datasheet revision 2022-09. This rating applies across the full operating temperature range (−65 °C to +150 °C) and defines the maximum DC or peak AC voltage the diode can block without breakdown in normal operation.
Can BAS40-05/DG/B3R be used in place of a single Schottky diode?
Yes - either anode can be used independently with the common cathode, effectively functioning as a standard Schottky diode. Pin 1 and Pin 2 form one diode; Pin 3 and Pin 2 form the second. Unused anode must be left open or tied to a non-conflicting potential to avoid unintended conduction paths.
Is BAS40-05/DG/B3R compatible with lead-free reflow soldering profiles?
Yes - the SOT-323 package is qualified for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The device meets RoHS Directive 2011/65/EU and REACH SVHC requirements as documented in Nexperia's material declaration.
Does BAS40-05/DG/B3R have a specified thermal resistance junction-to-case (RθJC)?
No - Nexperia specifies only junction-to-ambient thermal resistance (RθJA = 500 K/W) for the SOT-323 package on standard 1 cm² FR-4 PCB with 1 oz copper. RθJC is not published because the package lacks a dedicated thermal pad or exposed metal slug for case-based heat transfer.
