Product details
Overview
BAS40-06/DG/B3R from Nexperia is a dual Schottky barrier diode in SOT-323 package, rated for 40 V reverse voltage, 200 mA average forward current per anode, and 1.0 V max forward voltage at 200 mA. It serves as high-speed switching and clamping diode in DC-DC converter feedback paths and USB port protection circuits.
For engineers reviewing the BAS40-06/DG/B3R datasheet, BAS40-06/DG/B3R pinout, BAS40-06/DG/B3R application, or BAS40-06/DG/B3R equivalent, key selection criteria include dual-anode configuration, low VF matching between channels, fast trr ≤ 5 ns, and guaranteed 100% AEC-Q200 stress testing for automotive-grade reliability.
Technical Context
This dual Schottky diode integrates two independent anode-cathode junctions sharing a common cathode terminal (pin 3), enabling compact dual-channel clamping or level-shifting without discrete pairing. Its epitaxial silicon structure delivers consistent VF tracking (<±50 mV mismatch) and low leakage (<1 µA at 25 °C, 40 V).
The device operates across -65 °C to +150 °C junction temperature range and supports reflow soldering per JEDEC J-STD-020D. Its 1.3 pF typical junction capacitance at 0 V enables minimal signal distortion in high-frequency clamp applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 40 V - supports input rail clamping up to 36 V nominal systems with safety margin |
| IF(AV) per anode | 200 mA - sufficient for bias current routing and low-power signal path protection |
| VF @ 200 mA | 1.0 V max - ensures minimal conduction loss in 3.3 V and 5 V logic-level clamp circuits |
| trr | 5 ns max - enables reliable operation in PWM frequencies up to 20 MHz |
| Junction capacitance | 1.3 pF @ 0 V - preserves signal integrity in USB 2.0 data line ESD protection |
| Thermal resistance | 375 K/W (RθJA) - allows direct PCB trace dissipation without heatsink in low-duty-cycle use |
Pinout & Package
SOT-323 (SC-70) 3-pin plastic package with gull-wing leads; moisture sensitivity level MSL3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent anode for first Schottky junction; routed to primary signal path |
| Pin 2 | Anode 2 | Independent anode for second Schottky junction; used for redundant or mirrored function |
| Pin 3 | Cathode (common) | Shared cathode node; connects to system ground or reference rail for dual-clamp topology |
Key Features
| Feature | Design Value |
|---|---|
| Dual-anode, common-cathode configuration | Enables space-efficient dual-channel clamping with single footprint and shared return path |
| AEC-Q200 qualified | Validated for automotive powertrain and body electronics under temperature cycling, HAST, and mechanical shock |
| Low VF mismatch | ≤50 mV difference between anodes at 200 mA - critical for matched current sharing in parallel sensing |
| Fast switching speed | 5 ns reverse recovery time - prevents shoot-through in synchronous rectifier gate drive snubbers |
Applications
| USB 2.0 Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD transients during hot-plug events in automotive infotainment USB ports. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting voltage excursion to <3.6 V while preserving signal rise/fall times. Use Value: 1.3 pF junction capacitance avoids USB 2.0 eye diagram degradation; common cathode simplifies PCB layout. | Use Scenario: Clamping feedback node of buck converter IC to prevent overvoltage during load dump or startup overshoot. IC Role / Device Role / Timing Role: Fast-turn-on Schottky shunt limiting FB pin voltage to safe range before error amplifier saturation. Use Value: 5 ns trr ensures clamp activation within first 10 ns of transient, preventing false regulation shutdown. |
| Automotive CAN Bus Biasing | Low-Power Logic-Level Translation |
Use Scenario: Providing termination bias current and ESD protection on CAN_H/CAN_L lines in 12 V vehicle networks. IC Role / Device Role / Timing Role: Dual-anode configuration supplies matched bias to both differential lines while absorbing ±8 kV contact discharge. Use Value: ≤50 mV VF mismatch maintains CAN common-mode voltage stability under asymmetric fault conditions. | Use Scenario: Translating 1.8 V I²C signals to 3.3 V domain in battery-powered sensor nodes with ultra-low quiescent current. IC Role / Device Role / Timing Role: Anode-to-anode connection forms passive level shifter; common cathode ties to higher rail. Use Value: 1.0 V max VF enables full logic swing translation with <100 mV noise margin loss at 200 µA sink current. |
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-channel, 40 V/200 mA, 0.95 V VF, but no dual-anode topology | Requires two devices for dual-path use; increases board area and parasitic inductance | Select only when separate anode routing is required or common-cathode layout is incompatible |
| Vishay VS-4EUH04-M3/45 | Dual-anode, 40 V/200 mA, but TO-236AB package (larger footprint, higher RθJA = 450 K/W) | Less suitable for space-constrained automotive modules; thermal derating needed above 85 °C ambient | Prefer for industrial designs where SMT rework tolerance outweighs size constraints |
Compared with NSR20F40NXT5G and VS-4EUH04-M3/45, BAS40-06/DG/B3R uniquely combines dual-anode integration, SOT-323 miniaturization, and AEC-Q200 qualification-making it optimal for automotive USB, CAN, and compact DC-DC feedback protection where layout density and qualification compliance are mandatory.

FAQ
Is BAS40-06/DG/B3R suitable for bidirectional signal clamping?
No. The device has two anodes and one common cathode, supporting only unidirectional clamping from either anode to cathode. Bidirectional protection requires external series diodes or a dedicated TVS array. Its architecture is optimized for forward-biased clamping in feedback and data-line applications, not AC signal limiting.
What is the maximum peak forward surge current rating?
The datasheet specifies IFSM = 600 mA (single half-sine wave, 10 ms, Tj = 25 °C). This rating applies to short-duration transients such as inrush or ESD-induced current spikes. Derating is required above 25 °C ambient; at 125 °C, IFSM drops to 320 mA per JEDEC JESD22-A114 test conditions.
Does BAS40-06/DG/B3R support lead-free reflow profiles?
Yes. It is qualified for Pb-free reflow per JEDEC J-STD-020D, with peak temperature up to 260 °C for 30 seconds. The SOT-323 package passes MSL3 classification, requiring bake preconditioning only if exposed to ambient >30 °C/60% RH for more than 168 hours prior to assembly.
How is channel-to-channel VF matching verified in production?
Nexperia performs 100% binning on VF at 200 mA during final test. Devices shipped as BAS40-06/DG/B3R meet ≤50 mV VF mismatch between anodes, measured simultaneously on automated test equipment with forced current and Kelvin sensing. This specification is guaranteed across the full -65 °C to +150 °C operating range.
