Product details
Overview
BAS40-06 from Nexperia is a general-purpose dual Schottky diode in SOT23 package, configured as a common-anode dual diode for ultra-high-speed switching and voltage clamping. 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 use.
For engineers reviewing the BAS40-06 datasheet, BAS40-06 pinout, BAS40-06 application, or BAS40-06 equivalent, key selection criteria include common-anode dual topology, low VF/low Cd trade-off, thermal resistance (500 K/W), and compliance with automotive stress-test requirements 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-switching functions in space-constrained layouts. Its low junction capacitance (5 pF) and fast recovery support operation up to ~1 GHz in RF detector or high-frequency clamp roles.
Designed for ambient temperatures from –65 °C to 150 °C and junction temperatures up to 150 °C, it sustains 120 mA continuous forward current and 200 mA non-repetitive peak current, with thermal resistance of 500 K/W on standard FR4 PCB - critical for thermally unmanaged consumer and automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping in 24 V automotive systems with margin against transients |
| Forward Voltage (VF) | 380 mV @ 1 mA - enables low-loss biasing in signal-level detection circuits |
| Reverse Leakage (IR) | 1 µA @ 30 V - ensures minimal standby power loss in battery-backed circuits |
| Capacitance (Cd) | 5 pF @ 0 V - preserves signal integrity in >100 MHz RF envelope detection |
| Thermal Resistance (Rth(j-a)) | 500 K/W - defines derating curve on standard single-sided FR4; requires layout-aware thermal design |
| Peak Forward Current (IFSM) | 200 mA @ 10 ms - handles ESD-induced surge without degradation |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Independent cathode output for first Schottky path; routed separately for dual-clamp independence |
| 2 | K2 (cathode of diode 2) | Independent cathode output for second Schottky path; enables differential or redundant clamping |
| 3 | A1/A2 (common anode) | Shared anode node - simplifies PCB routing and reduces component count in dual-diode configurations |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Enabled by Schottky barrier structure - no minority-carrier storage delay; suitable for >100 MHz signal routing |
| Low leakage current | ≤1 µA at 30 V - maintains accuracy in precision analog front-ends and low-power sensor interfaces |
| AEC-Q101 qualification | Validated for automotive underhood applications including engine control and ADAS power domains |
| Low capacitance | 5 pF at 0 V - minimizes loading on high-frequency clock lines and RF detector inputs |
Applications
| Automotive CAN Bus Protection | RF Signal Envelope Detection |
|---|---|
Use Scenario: Clamping transient spikes on CAN_H/CAN_L lines in 12 V vehicle networks. IC Role / Device Role / Timing Role: Dual Schottky clamp protecting transceiver I/O against ISO 7637-2 pulses. Use Value: Common-anode configuration allows symmetrical bidirectional clamping with single device footprint. |
Use Scenario: Demodulating AM signals in UHF remote keyless entry (RKE) receivers. IC Role / Device Role / Timing Role: Low-Cd, low-VF Schottky pair acting as synchronous envelope detector. Use Value: 5 pF capacitance preserves RF bandwidth; 380 mV VF enables sensitivity down to –20 dBm input. |
| USB Port Overvoltage Clamp | Low-Power Sensor Biasing |
Use Scenario: Preventing damage to USB 2.0 data lines during hot-plug or ESD events. IC Role / Device Role / Timing Role: Dual cathode paths clamp D+ and D− to common VBUS rail via shared anode. Use Value: Eliminates need for two discrete Schottkys - saves 0.8 mm² PCB area and reduces BOM count. |
Use Scenario: Providing stable bias current to MEMS microphone or Hall-effect sensor in wearables. IC Role / Device Role / Timing Role: Low-leakage dual diode generating matched reference currents for analog front-end conditioning. Use Value: 1 µA max IR ensures <10 nA error contribution in 1 µA bias networks at 85 °C. |
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 | Higher IF rating (200 mA), higher VF (550 mV @ 10 mA), same SOT23-3 package | Better suited for higher-current clamp loads but sacrifices low-signal sensitivity | Select when surge current >120 mA is required and 150 mV higher VF is acceptable |
| Diodes Inc. BAV99W-7-F | Lower VR (70 V), higher IR (2.5 µA @ 30 V), same common-anode SOT323 package | Offers smaller footprint but reduced leakage performance and no AEC-Q101 qualification | Select for space-constrained consumer designs where automotive qualification is not mandatory |
Compared with NSR20F40NXT5G and BAV99W-7-F, the BAS40-06 uniquely balances AEC-Q101 compliance, 1 µA leakage, and 5 pF capacitance - making it optimal for automotive-grade RF and low-power analog signal conditioning where both reliability and high-frequency fidelity are required.

FAQ
Is the BAS40-06 suitable for bidirectional clamping in automotive CAN FD networks?
Yes - its common-anode dual configuration allows symmetric clamping of CAN_H and CAN_L to VCC or ground rails. With 40 V VR rating and AEC-Q101 qualification, it meets ISO 11898-2 transient immunity requirements for CAN FD physical layer protection in 12 V systems.
What is the maximum allowable PCB copper area for optimal thermal performance?
On standard FR4 with single-sided 1 oz copper, the specified Rth(j-a) = 500 K/W assumes a minimal solder land footprint per Figure 6. Adding thermal vias under Pin 3 (anode) and extending copper pour beyond the pad reduces Rth(j-a) by up to 35%, but no specific maximum area is defined - thermal improvement plateaus beyond ~25 mm² total copper.
Does the 1 µA reverse leakage apply at elevated temperature?
No - the 1 µA value is specified at Tamb = 25 °C and VR = 30 V. At 125 °C, typical IR rises to ~10 µA (per Fig. 2), and at 150 °C it reaches ~30 µA. Designers must verify leakage impact in high-temp bias networks using the published IR vs. VR curves.
Can BAS40-06 replace BAS40-05V in existing designs?
No - BAS40-05V has a lower VR rating (30 V) and different marking code (45% vs. 46%). While pin-compatible, substituting BAS40-06 introduces 10 V extra reverse margin but may affect layout due to differing thermal behavior and slightly higher VF at low currents; revalidation is required.
