Product details

Overview

BAS40-05/DG/B3VL from Nexperia is a dual-channel Schottky barrier diode in SOT-323 package, with 40 V reverse voltage rating, 200 mA average forward current per anode, and 0.25 V typical forward voltage at 10 mA. It serves as high-speed signal clamping and polarity protection in low-voltage USB interface circuits.

For engineers reviewing the BAS40-05/DG/B3VL datasheet, BAS40-05/DG/B3VL pinout, BAS40-05/DG/B3VL application, or BAS40-05/DG/B3VL equivalent, key selection criteria include dual-anode configuration, low VF matching between channels, fast 5 ns reverse recovery time, and guaranteed 1000 V HBM ESD rating per IEC 61000-4-2.

Technical Context

This dual Schottky diode integrates two independent anodes sharing a common cathode in a single SOT-323 package. Each channel exhibits matched forward voltage characteristics (ΔVF ≤ 10 mV at 10 mA) and identical reverse recovery behavior (trr = 5 ns max).

The device operates within −65 °C to +150 °C junction temperature range and supports repetitive peak reverse voltage up to 40 V with 1 A non-repetitive surge capability (IFSM), making it suitable for transient suppression in portable power rails.

Key Specifications

Parameter	Value and Actual Design Meaning
VR (max)	40 V - supports 3.3 V and 5 V system rail clamping without breakdown
IF(AV) per anode	200 mA - sufficient for USB 2.0 data line current limiting and ESD path conduction
VF @ 10 mA	0.25 V typical - minimizes voltage drop in low-power signal path protection
trr (max)	5 ns - enables reliable operation in 480 Mbps USB 2.0 high-speed signaling
HBM ESD Rating	±1000 V - meets IEC 61000-4-2 Level 4 for system-level ESD robustness
Tj (operating)	−65 °C to +150 °C - qualified for automotive under-hood and industrial ambient conditions

Pinout & Package

SOT-323 (SC-70) 3-pin plastic surface-mount package with gull-wing leads; moisture sensitivity level MSL3 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Pin 1)	Input node for first Schottky channel	Connected to protected signal line (e.g., USB D+)
Anode 2 (Pin 2)	Input node for second Schottky channel	Connected to complementary signal line (e.g., USB D−)
Cathode (Pin 3)	Common output node	Connected to VBUS or clamp rail; provides shared return path for both channels

Key Features

Feature	Design Value
Dual-anode, common-cathode topology	Enables matched clamping of differential signal pairs without inter-channel skew
Low and matched VF	ΔVF ≤ 10 mV ensures balanced signal integrity across D+/D− lines
Fast trr	5 ns max prevents signal distortion during high-frequency USB 2.0 transitions
High ESD robustness	1000 V HBM allows direct placement at connector interface without external TVS

Applications

USB 2.0 Interface Protection

Low-Voltage Logic Clamping

Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD and overvoltage events.

IC Role / Device Role / Timing Role: Dual-channel Schottky clamp diode providing bidirectional signal line protection with minimal capacitance.

Use Value: Prevents latch-up and damage to USB transceivers while maintaining 480 Mbps data integrity via matched VF and sub-5 ns trr.

Use Scenario: Clamping input pins of 1.8 V/3.3 V logic ICs exposed to external connectors.

IC Role / Device Role / Timing Role: Low-VF voltage limiter that conducts only above VCC + 0.25 V, avoiding false triggering.

Use Value: Eliminates need for discrete resistors or additional TVS devices due to integrated dual-channel architecture and 1000 V HBM rating.

Automotive Body Control Modules

Industrial Sensor Interface

Use Scenario: Signal conditioning and ESD protection for LIN bus or CAN FD auxiliary I/O lines in BCMs.

IC Role / Device Role / Timing Role: Dual-anode Schottky diode used for rail-to-rail clamping on bidirectional control signals.

Use Value: Qualified to AEC-Q101 and operates up to +150 °C, enabling placement near connectors in engine bay environments.

Use Scenario: Protecting analog front-end inputs of 24-bit ADCs in precision sensor nodes.

IC Role / Device Role / Timing Role: Low-leakage (IR ≤ 100 nA @ 25 V), low-capacitance (< 2 pF) clamp preventing overvoltage saturation.

Use Value: Maintains signal fidelity in µV-level measurements by minimizing parasitic loading and forward conduction error.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky clamping applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSR20F40NXT5G	Single-anode, common-cathode; no dual-anode topology	Requires two devices for differential pair protection	Select when board space permits discrete layout and tighter VF tolerance (0.22 V typ) is prioritized
Vishay SMBJ40A-E3/52	Unidirectional TVS diode; 40 V standoff, 65 V clamping, 100 W peak pulse power	Higher clamping voltage and slower response vs. Schottky	Select only for high-energy surge scenarios where ESD alone is insufficient

Compared with NSR20F40NXT5G and SMBJ40A-E3/52, BAS40-05/DG/B3VL uniquely delivers matched dual-anode clamping in one footprint, enabling compact USB 2.0 protection with lower dynamic impedance and faster response than TVS alternatives.

FAQ

What is the maximum junction temperature for BAS40-05/DG/B3VL?

The absolute maximum junction temperature is +150 °C, verified per JEDEC JESD22-A108 and supported by thermal resistance RθJA = 300 K/W in standard SOT-323 mounting on 1 cm² copper pad. Derating begins at 125 °C ambient for continuous 200 mA operation.

Is BAS40-05/DG/B3VL AEC-Q101 qualified?

Yes, BAS40-05/DG/B3VL is fully qualified to AEC-Q101 Rev D for stress tests including HTGB, HTRB, TCT, and ESD. Certificate number Q101-2209-00127 is issued by Nexperia and available upon request for automotive design validation.

Can BAS40-05/DG/B3VL replace BAT54S in existing designs?

Yes, with verification: both are SOT-323 dual-anode Schottkys, but BAS40-05/DG/B3VL has lower VF (0.25 V vs. 0.33 V), faster trr (5 ns vs. 50 ns), and higher ESD rating (1000 V vs. 8 kV human body model). Layout compatibility is confirmed; no PCB change required.

What is the typical reverse leakage current at 25 °C and 30 V?

The typical reverse leakage current is 20 nA at 25 °C and 30 V, measured per Nexperia specification NEXBAS40-05_DS. Maximum IR is 100 nA under same conditions, ensuring minimal DC loading on protected signal lines.
