Product details
Overview
BAS40-05V from Nexperia is a general-purpose quadruple Schottky diode in SOT666 package, configured as two independent dual-anode/common-cathode pairs (D1/D2 share K1–K2; D3/D4 share K3–K4), with 40 V reverse voltage rating, 120 mA forward current capability, and 380 mV typical forward voltage at 1 mA - used for ultra high-speed switching and voltage clamping in compact DC-DC converter feedback paths and signal line protection.
For engineers reviewing the BAS40-05V datasheet, BAS40-05V pinout, BAS40-05V application, or BAS40-05V equivalent, key selection criteria include its quad-diode topology with split common cathodes, low 5 pF capacitance at 0 V, sub-1 µA reverse leakage at 30 V, thermal resistance of 225 K/W on FR4, and compatibility with reflow soldering per SOT666 footprint.
Technical Context
The BAS40-05V integrates four discrete Schottky diodes in a single ultra-small SOT666 package, arranged as two electrically isolated dual-diode sections: pins 1–2–6 form one pair (A1, A2, K1/K2), and pins 3–4–5 form the second (K3/K4, A3, A4). This configuration enables independent clamping or steering functions without shared cathode impedance coupling.
Its Schottky junction delivers fast recovery (no minority-carrier storage), low forward voltage drop across 1–40 mA range (380–1000 mV), and minimal capacitance (5 pF at 0 V, 1 MHz), making it suitable for RF detector biasing, high-frequency rectification, and transient suppression where parasitic capacitance must remain below 6 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode Count | 4 independent Schottky diodes, grouped into two isolated dual-anode/common-cathode structures |
| VR (Reverse Voltage) | 40 V maximum - supports clamping in 24 V industrial bus lines and 3.3/5/12 V logic-level protection |
| VF @ 1 mA | 380 mV typical - enables low-loss biasing in RF detector circuits and precision clamp references |
| IR @ 30 V | 1 µA typical - ensures minimal leakage in high-impedance sample-and-hold or sensor interface nodes |
| Cd @ 0 V | 5 pF typical at 1 MHz - preserves signal integrity in >100 MHz clock distribution or RF envelope detection |
| Rth(j-a) | 225 K/W on FR4, single-sided copper - defines thermal derating above 75 °C ambient in unforced-air applications |
| Tj(max) | 150 °C - allows operation in sealed enclosures with limited airflow, such as industrial IoT gateways |
Pinout & Package
Package: SOT666 - ultra-small surface-mount plastic package, 1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm lead pitch, 6-terminal outline with pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Anode of Diode 2 (A2) | Independent anode for second diode in first dual-diode section; enables dual-rail clamping |
| 3 | Common Cathode of Diodes 3 & 4 (K3/K4) | Shared return path for third and fourth diodes; electrically isolated from K1/K2 |
| 4 | Anode of Diode 3 (A3) | Second independent clamping input; paired with pin 3 for isolated bias or level-shift function |
| 5 | Anode of Diode 4 (A4) | Fourth anode terminal; completes quad-diode set with dedicated cathode grouping |
| 6 | Common Cathode of Diodes 1 & 2 (K1/K2) | Shared cathode for first dual-diode section; enables compact dual-input/single-output clamping |
Key Features
| Feature | Design Value |
|---|---|
| Quad Schottky integration | Four discrete diodes in one SOT666 footprint - saves >60% board area vs. four SOD-323 devices |
| Split common cathodes | Two isolated cathode groups (pins 3 & 6) - prevents cross-talk between clamped signals |
| Low 5 pF capacitance | Enables use in 100+ MHz RF detector and mixer bias networks without detuning |
| 380 mV VF @ 1 mA | Reduces forward loss in precision voltage reference clamps and low-current sensing paths |

Applications
| DC-DC Converter Feedback Clamping | High-Speed Logic Signal Protection |
|---|---|
|
Use Scenario: Clamp feedback node of synchronous buck converter to prevent overvoltage during light-load or startup transients. IC Role / Device Role: Quad Schottky provides dual-path clamping (VOUT to REF and REF to GND) using independent cathode groups. Use Value: 380 mV VF ensures tight regulation window; 5 pF capacitance avoids phase shift in error amplifier loop. |
Use Scenario: Protect FPGA I/O pins from ESD and overshoot on 3.3 V LVCMOS buses operating up to 200 MHz. IC Role / Device Role: Two diodes steer positive transients to VCC; two steer negative transients to GND via split cathodes. Use Value: Sub-1 µA leakage preserves signal integrity; 40 V VR withstands ±15 kV HBM ESD events. |
| RF Detector Bias Network | Multi-Rail Power Sequencing |
|
Use Scenario: Provide temperature-stable bias current to Schottky RF detector diode in 2.4 GHz Wi-Fi front-end modules. IC Role / Device Role: One diode supplies forward-biased current path; others isolate bias rails from RF coupling paths. Use Value: Low 5 pF capacitance prevents RF leakage into bias supply; 150 °C Tj(max) supports operation near PA stages. |
Use Scenario: Control power-up sequence of dual-core SoC with separate 1.2 V core and 3.3 V I/O rails using diode-based OR-ing. IC Role / Device Role: Two diodes enable independent rail enable timing; split cathodes avoid ground bounce coupling. Use Value: 120 mA IF rating supports 50 mA sequencing currents; 225 K/W Rth(j-a) allows 100% duty-cycle operation at 70 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR40F40T1G | SOT-23-6 package; 40 V VR; 390 mV VF @ 1 mA; 10 pF Cd - larger capacitance, same voltage rating | Less suitable for >50 MHz RF biasing due to higher capacitance; better thermal pad layout for power dissipation | Select when board space permits larger footprint and thermal performance outweighs RF sensitivity |
| Diodes Inc. SDM40E3-7 | SOT-26 package; 40 V VR; 450 mV VF @ 1 mA; 8 pF Cd; 150 °C Tj - higher VF, higher Cd, same thermal limit | Acceptable for DC-DC clamping but degrades RF detector SNR; lower leakage (0.5 µA @ 30 V) | Prefer for cost-sensitive industrial controls where RF performance is not required |
Compared with NSR40F40T1G and SDM40E3-7, the BAS40-05V offers the lowest capacitance (5 pF) and lowest VF (380 mV), making it optimal for RF and precision analog clamping, while its SOT666 footprint delivers superior board-area efficiency in space-constrained designs.

FAQ
What is the maximum continuous forward current per diode in the BAS40-05V?
The absolute maximum continuous forward current per diode is 120 mA, as specified in Table 5 (Limiting values) under "IF forward current" at Tj = 25 °C. Derating applies above 25 °C ambient, governed by Rth(j-a) = 225 K/W on FR4 PCB.
Can the BAS40-05V be used in automotive applications?
No - the datasheet explicitly states this device is non-automotive qualified. It has not undergone AEC-Q101 stress testing or qualification for automotive temperature ranges, reliability, or failure mechanisms, and Nexperia disclaims liability for automotive use.
How are the four diodes internally connected in the SOT666 package?
Diodes 1 and 2 share common cathode pins 6 (K1/K2); diodes 3 and 4 share common cathode pins 3 (K3/K4). Anodes are on pins 1 (A1), 2 (A2), 4 (A3), and 5 (A4), forming two electrically isolated dual-diode sections with no internal interconnection between cathode groups.
What is the recommended reflow profile for BAS40-05V soldering?
The device is qualified for standard Pb-free reflow per JEDEC J-STD-020. Figure 6 provides the exact SOT666 land pattern: 0.5 mm pitch, 0.25 mm wide solder paste apertures, and 0.375 mm × 0.45 mm pad dimensions - matching IPC-7351B density level A for reliable tombstoning-free assembly.
