Product details
Overview
BAS40-06Q-7-F from Diodes Incorporated is a 40 V, 200 mA surface-mount Schottky barrier diode in SOT23 package, featuring 380 mV typical forward voltage at 1 mA, 5.0 ns reverse recovery time, and PN junction guard ring for ESD/transient protection-used in automotive power rail clamping and low-loss DC-DC converter freewheeling paths.
For engineers reviewing the BAS40-06Q-7-F datasheet, BAS40-06Q-7-F pinout, BAS40-06Q-7-F application, or BAS40-06Q-7-F equivalent, key selection criteria include low VF under light-load conditions, AEC-Q101 qualification for automotive use, IR ≤ 200 nA at 30 V reverse bias, and SOT23 thermal resistance of 357 °C/W on FR-4 board.
Technical Context
This Schottky diode uses a planar epitaxial structure with integrated PN guard ring to suppress edge breakdown and improve ESD robustness (HBM > 8 kV per AEC-Q101). Its low junction capacitance (4.0–5.0 pF at 0 V) supports high-frequency switching in flyback snubbers and RF detector circuits.
The device operates across −55 °C to +125 °C junction temperature, with power derating beginning above 25 °C ambient; maximum forward surge current is 600 mA for <1 s pulses, enabling reliable inrush handling in automotive load-dump scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24 V automotive systems with transient spikes. |
| IF | 200 mA continuous - Sustained forward current rating; suitable for signal-level rectification and low-power supply OR-ing. |
| VF Max | 1.0 V at 40 mA - Ensures minimal conduction loss in battery-powered sensor nodes and low-voltage logic clamping. |
| IR Max | 200 nA at 30 V - Ultra-low leakage preserves battery life in always-on IoT wake-up circuits. |
| trr | 5.0 ns - Enables clean switching in >10 MHz clocked clamp circuits without tail current artifacts. |
| CT | 5.0 pF at 0 V - Limits capacitive loading on high-speed data lines when used as ESD protection element. |
| RθJA | 357 °C/W - Requires minimal PCB copper area for thermal management in space-constrained automotive modules. |
Pinout & Package
Package: SOT23 (Standard), 3-terminal plastic molded case, 0.008 g mass, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or rectification path; polarity-marked on top surface. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Typically tied to ground or lower-rail reference; carries full reverse voltage during off-state. |
| No-Connect (Pin 3) | Internal die attach pad | Electrically isolated; serves mechanical anchoring and thermal conduction to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 380 mV typical at 1 mA - Reduces power loss in low-current bias networks and precision voltage references. |
| Fast switching | 5.0 ns reverse recovery - Eliminates switching glitches in high-frequency synchronous rectifier control loops. |
| ESD/Transient protection | PN junction guard ring - Provides inherent HBM > 8 kV and system-level IEC 61000-4-2 compliance without external TVS. |
| AEC-Q101 qualification | Qualified for automotive applications - Validated for temperature cycling, humidity testing, and mechanical shock per IATF 16949 process controls. |
Applications
| Automotive Power Rail Clamping | Low-Voltage DC-DC Freewheeling |
|---|---|
Use Scenario: Suppressing load-dump transients on 12 V/24 V vehicle subsystems (e.g., infotainment power input). IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between rail and ground to shunt surge energy. Use Value: 40 V VRRM and 600 mA IFSM withstand ISO 7637-2 Pulse 5a without degradation. |
Use Scenario: Freewheeling path in 3.3 V buck converter supplying microcontroller core voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54ALT1G | Higher VF (450 mV typ @ 10 mA); same SOT23 package; no AEC-Q101 qualification. | Not approved for automotive production; limited to industrial/commercial power management. | Select only if AEC-Q101 is not required and 70 mV higher VF is acceptable in thermal budget. |
| NSR0230P2T5G | Lower IF rating (200 mA avg, 500 mA peak); 30 V VRRM; 300 mV VF @ 10 mA. | Suitable for 5 V/3.3 V systems only; insufficient for 24 V automotive rails. | Prefer for consumer USB power path OR-ing where 30 V blocking suffices and ultra-low VF is critical. |
Compared with SBAT54ALT1G and NSR0230P2T5G, BAS40-06Q-7-F uniquely combines AEC-Q101 qualification, 40 V blocking, and sub-400 mV VF at microamp bias-making it the only choice for automotive-grade low-leakage clamping in extended-temperature environments.

FAQ
Is BAS40-06Q-7-F pin-compatible with standard SOT23 Schottky diodes?
Yes, BAS40-06Q-7-F uses the standard SOT23-3 footprint with Anode on Pin 1, Cathode on Pin 2, and internal die attach on Pin 3. It matches IPC-7351B SOT23-3 land pattern dimensions (2.90 mm × 1.35 mm pad layout) and is mechanically interchangeable with other SOT23 Schottky diodes like BAT54 series, though electrical parameters differ.
What is the significance of the "Q" suffix in BAS40-06Q-7-F?
The "Q" denotes AEC-Q101 qualification and PPAP capability. These parts are manufactured in IATF 16949-certified facilities, undergo automotive-specific stress testing (including temperature cycling, HTOL, and ESD), and are traceable to lot-level automotive quality documentation-distinguishing them from commercial-grade BAS40-06-7-F.
Can BAS40-06Q-7-F be used in reverse-biased ESD protection configurations?
Yes-it is routinely deployed as a bidirectional rail clamp using two devices in series opposition. Its PN guard ring provides intrinsic 8 kV HBM ESD immunity, and its 200 nA IR at 30 V ensures negligible standby current when protecting low-power 1.8 V or 3.3 V I/O lines in automotive MCUs.
How does the 357 °C/W RθJA value translate to real-world thermal performance?
On a standard 1 oz FR-4 board with recommended 2.0 mm × 0.8 mm copper pads and no thermal vias, the junction rises 357 °C above ambient per watt dissipated. At 200 mA and 380 mV VF, power dissipation is 76 mW, resulting in ~27 °C junction rise-well within the −55 °C to +125 °C operating range even at 98 °C ambient.
