Product details
Overview
BAS40-07 from Nexperia is a general-purpose dual Schottky diode in SOT143B package, configured as two independent low-capacitance (5 pF), low-forward-voltage (380 mV @ 1 mA) diodes with 40 V reverse voltage rating and AEC-Q101 qualification-used for ultra high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS40-07 datasheet, BAS40-07 pinout, BAS40-07 application, or BAS40-07 equivalent, key selection criteria include pulsed forward voltage consistency across temperature, reverse leakage stability up to 125 °C, dual-diode isolation integrity, and SOT143B thermal resistance (500 K/W) in FR4 PCB layouts.
Technical Context
The BAS40-07 integrates two electrically isolated Schottky diodes in a single 4-pin surface-mount package, enabling compact dual-path clamping or steering without cross-talk. Its junction temperature rating of 150 °C and ambient range of −65 °C to +150 °C support operation in under-hood automotive environments.
Designed for pulsed operation (tp ≤ 300 µs, duty cycle δ ≤ 0.02), it delivers stable VF (380–1000 mV across 1–40 mA) and low IR (≤10 µA @ 40 V), with diode capacitance held to 5 pF at 0 V and 1 MHz-critical for RF-sensitive signal routing and ESD front-end protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 380 mV @ 1 mA (pulsed); ensures minimal voltage drop in low-current bias networks and logic-level clamping. |
| Reverse Voltage (VR) | 40 V max; supports rail-to-rail clamping in 24 V automotive systems with margin against transients. |
| Reverse Current (IR) | ≤10 µA @ 40 V, 25 °C; guarantees low standby power loss in always-on monitoring circuits. |
| Diode Capacitance (Cd) | 5 pF @ 0 V, 1 MHz; preserves signal integrity in >100 MHz data lines and RF detector inputs. |
| Thermal Resistance (Rth(j-a)) | 500 K/W (FR4, single-sided copper); defines derating curve for continuous 120 mA operation in constrained thermal layouts. |
| Junction Temperature (Tj) | 150 °C max; enables reliable use in engine control units and ADAS sensor interfaces without active cooling. |
Pinout & Package
Package: SOT143B - 4-lead, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, optimized for automated reflow assembly on FR4 PCBs with standard footprint per Fig. 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode, diode 1) | Reference node for first diode's cathode; connects to clamped signal return or regulated rail. |
| 2 | K2 (cathode, diode 2) | Independent cathode for second diode; allows separate biasing or dual-rail clamping paths. |
| 3 | A2 (anode, diode 2) | Input terminal for second diode; used for bidirectional signal steering or redundant protection. |
| 4 | A1 (anode, diode 1) | Input terminal for first diode; commonly tied to I/O line or sensor output for fast transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Enabled by low junction capacitance (5 pF) and Schottky barrier physics-supports <1 ns recovery in pulse-clamp applications. |
| Low leakage current | IR ≤1 µA @ 30 V, 25 °C; minimizes DC error in precision analog front-ends and battery-monitoring dividers. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing-approved for powertrain and body electronics. |
| Small SOT143B footprint | 2.9 × 1.3 mm area saves >40% board space vs. dual-SOD-323 solutions-ideal for dense ADAS camera modules and radar receivers. |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines from ISO 7637-2 pulse 1/2b transients in vehicle ECUs. IC Role / Device Role / Timing Role: Dual-diode clamp referenced to VCC and GND-each diode handles one differential line independently. Use Value: 40 V VR rating absorbs 24 V system surges while 5 pF capacitance avoids signal edge degradation at 1 Mbps CAN FD rates. |
Use Scenario: ESD and overvoltage protection on D+/D− lines of USB 2.0 host ports in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamping device placed directly at connector interface. Use Value: 380 mV VF at 1 mA ensures minimal impact on USB eye diagram; AEC-Q101 status validates long-term reliability in hot/cold cycling. |
| RF Detector Input Protection | Low-Power Sensor Bias Steering |
Use Scenario: Safeguarding input of 2.4 GHz Wi-Fi/BLE RF detectors in telematics modules from antenna coupling spikes. IC Role / Device Role / Timing Role: High-frequency shunt clamp between RF path and ground/VDD rails using both diodes in parallel configuration. Use Value: 5 pF Cd maintains detector sensitivity above −70 dBm; 150 °C Tj rating sustains performance near RF power amplifiers. |
Use Scenario: Steering bias current between two temperature sensors in a redundant HVAC control unit. IC Role / Device Role / Timing Role: Dual-anode/cathode discrete switch enabling automatic path selection based on sensor health status. Use Value: Matched VF across diodes (<±50 mV) ensures balanced current division; SOT143B thermal symmetry minimizes drift-induced offset. |
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 NSR20F40HT1G | Higher IF rating (200 mA), larger SOD-523 package (1.2 × 0.8 mm), VF = 450 mV @ 1 mA. | Preferred where higher surge current handling is needed but board space is less constrained. | Select when peak repetitive current exceeds 120 mA and thermal mass can accommodate larger Rth(j-a). |
| Vishay SDURB140 | SOT-23-3 package (single diode), 40 V VR, VF = 490 mV @ 1 mA, no AEC-Q101 qualification. | Requires two devices for dual function; unsuitable for automotive production without additional qualification. | Use only in non-automotive industrial designs where cost is prioritized over qualification and integration density. |
Compared with NSR20F40HT1G and SDURB140, the BAS40-07 uniquely combines AEC-Q101 compliance, true dual-diode integration in SOT143B, and sub-400 mV VF at microamp bias-making it optimal for space-constrained, safety-critical automotive signal paths requiring guaranteed qualification and matched characteristics.

FAQ
Is the BAS40-07 suitable for continuous DC operation at 120 mA?
No. The 120 mA rating is for pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02). Continuous DC current must be derated based on thermal resistance (500 K/W) and ambient temperature-maximum safe DC current is ~24 mA at Tamb = 70 °C on standard FR4.
Can BAS40-07 replace BAS40-05 in existing designs?
Yes, with verification. Both share SOT143B package and dual-diode topology, but BAS40-05 has 30 V VR and lower VF (350 mV @ 1 mA). Substitution requires confirming that 40 V VR and 30 mV VF increase meet system transient and bias requirements.
What is the meaning of the '47%' marking on the device body?
The '47%' marking indicates the device type code '47' followed by a placeholder '%' for the manufacturing site identifier. This matches Nexperia's standard SOT143B marking convention per Table 4 and is not a performance parameter.
Does BAS40-07 support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint dimensions (Fig. 7) and process guidelines. Recommended parameters include preheat ≤100 °C, peak temperature 245–260 °C, and contact time ≤5 s to avoid thermal stress on the plastic package.
