Product details
Overview
BAS40-06 from Nexperia is a general-purpose dual Schottky diode in SOT23 package, configured as a common-anode pair with cathodes on pins 1 and 2. It delivers 40 V reverse voltage rating, ≤1 µA reverse leakage at 30 V, 380–1000 mV forward voltage across 1–40 mA, 5 pF capacitance at 0 V, and AEC-Q101 qualification for automotive signal clamping and ultra-high-speed switching.
For engineers reviewing the BAS40-06 datasheet, BAS40-06 pinout, BAS40-06 application, or BAS40-06 equivalent, key selection criteria include common-anode dual-diode topology, low VF/low Cd trade-off, thermal resistance (500 K/W), junction temperature limit (150 °C), and automotive-grade reliability validation per AEC-Q101.
Technical Context
The BAS40-06 integrates two independent Schottky diodes sharing a single anode terminal (pin 3), enabling compact dual-clamp or dual-rectifier functions in space-constrained layouts. Its low forward voltage (380 mV @ 1 mA) and minimal junction capacitance (5 pF @ 0 V) support high-frequency signal integrity in RF front-ends and logic-level translation circuits.
Thermal performance is defined by a junction-to-ambient resistance of 500 K/W on standard FR4 PCBs, with absolute maximum ratings including 120 mA continuous forward current and 200 mA non-repetitive peak current. The device operates across –65 °C to +150 °C ambient and junction temperatures, meeting automotive environmental stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability without breakdown; suitable for 3.3 V/5 V/12 V rail clamping. |
| Forward Voltage (VF) | 380 mV @ 1 mA - Enables low-loss biasing and level-shifting in battery-powered logic interfaces. |
| Reverse Current (IR) | 1 µA @ 30 V - Ensures minimal standby power loss in always-on protection circuits. |
| Diode Capacitance (Cd) | 5 pF @ 0 V, 1 MHz - Supports >100 MHz signal routing without excessive AC coupling distortion. |
| Junction Temperature (Tj) | 150 °C - Allows operation in under-hood automotive environments without derating. |
| Thermal Resistance (Rth(j-a)) | 500 K/W - Defines power dissipation limit (~250 mW max at ΔT = 125 K) on standard PCB layout. |

Applications
| Automotive Sensor Signal Clamping | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting analog outputs of MEMS pressure sensors in engine control units from load-dump transients and ESD. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting signal swing to VCC + 0.4 V and GND − 0.4 V via common-anode topology. Use Value: Prevents op-amp input saturation during ±15 kV ESD events while maintaining <1 ns response time due to low Cd and VF. |
Use Scenario: Bidirectional ESD protection on D+ and D− lines of embedded USB host controllers. IC Role / Device Role / Timing Role: Common-anode pair shunting transients to VBUS and GND simultaneously without adding series impedance. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air) with <0.5 pF parasitic increase per line, preserving signal integrity up to 480 Mbps. |
| Low-Voltage Logic Level Translation | RF Detector Bias Network |
Use Scenario: Translating 1.8 V GPIO signals to 3.3 V microcontroller inputs in portable medical devices. IC Role / Device Role / Timing Role: Forward-biased Schottky diode pulling up to 3.3 V rail while blocking reverse current from 1.8 V side. Use Value: Achieves sub-10 ns propagation delay with no external pull-up resistor needed, reducing BOM count and board space. |
Use Scenario: Providing temperature-stable DC bias to GaAs FET detectors in 2.4 GHz Wi-Fi front-ends. IC Role / Device Role / Timing Role: Low-Cd, low-VF Schottky providing stable DC path while minimizing RF insertion loss at detector input. Use Value: Maintains detector sensitivity within ±0.3 dB across –40 °C to +85 °C due to stable VF and negligible self-heating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single N-channel MOSFET with integrated Schottky (not dual-diode); 20 V VDS, 1.6 A ID. | Designed for synchronous rectification, not signal clamping; lacks dual-cathode isolation. | Select only if replacing discrete MOSFET + Schottky combo in DC-DC output stage. |
| BAT54C | Common-cathode dual Schottky (vs. BAS40-06's common-anode); identical SOT23 package, 30 V VR, 240 mV VF @ 10 mA. | Requires inverted PCB layout (cathodes tied, anodes separate); unsuitable for VCC-referenced clamping. | Choose when clamping to ground is preferred; verify pin compatibility before layout reuse. |
Compared with BAT54C and DMN2016LFG-7, the BAS40-06 uniquely supports VCC-referenced dual clamping in a single footprint, offering higher reverse voltage (40 V vs. 30 V) and lower leakage (1 µA vs. 2 µA) - critical for automotive sensor interfaces requiring long-term stability.

FAQ
What is the maximum continuous forward current for BAS40-06?
The BAS40-06 supports 120 mA continuous forward current per diode at Tamb = 25 °C, derated linearly above 25 °C ambient based on its 500 K/W thermal resistance. At 85 °C ambient, maximum continuous current drops to approximately 85 mA to maintain Tj ≤ 150 °C.
Can BAS40-06 be used for reverse polarity protection?
No - the BAS40-06 is a common-anode dual Schottky diode optimized for clamping and signal steering, not series blocking. Its structure lacks a single high-current path capable of sustaining reverse-polarity fault currents; dedicated ideal diode controllers or P-channel MOSFETs are recommended instead.
Is the marking code "46%" consistent across all BAS40-06 production lots?
Yes - "46" is the fixed type identification code per Nexperia's marking standard; the trailing "%" is a placeholder for the manufacturing site code (e.g., "46A" for Hamburg, "46B" for Nijmegen), which varies by lot but does not affect electrical or mechanical specifications.
How does BAS40-06 perform under pulsed conditions beyond datasheet limits?
The BAS40-06 supports 200 mA non-repetitive peak forward current for tp ≤ 10 ms at Tj(init) = 25 °C. Exceeding this - such as 500 mA pulses - risks irreversible junction damage due to localized thermal runaway, even if average power remains within limits; pulse testing must follow IEC 60134 stress guidelines.
