Product details
Overview
BAS40V-7 from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode in SOT-563 package, rated for 40 V peak reverse voltage, 200 mA continuous forward current, and featuring low 380–1000 mV forward voltage at 1–40 mA. It integrates PN junction guard ring for ESD/transient protection and is used in compact DC-DC converter output rectification and high-frequency signal clamping.
For engineers reviewing the BAS40V-7 datasheet, BAS40V-7 pinout, BAS40V-7 application, or BAS40V-7 equivalent, key selection criteria include its 5.0 ns reverse recovery time, 4.0–5.0 pF junction capacitance at 0 V, 833 °C/W thermal resistance, RoHS-compliant matte tin terminals, and dual-diode configuration with two anodes and two cathodes in a 6-pin micro-SMD package.
Technical Context
The BAS40V-7 integrates two independent Schottky diodes sharing no internal connection-each has separate anode and cathode terminals. Its guard-ringed structure suppresses avalanche-induced failure during transient events, enabling reliable operation in noisy power rails and RF-coupled signal paths.
Designed for high-speed switching up to ~100 MHz, it leverages low-junction-capacitance (4.0–5.0 pF) and fast trr (≤5.0 ns) to minimize switching loss and ringing in buck converter freewheeling paths and precision sample-and-hold clamp circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage before breakdown; sets upper limit for DC-DC output rail or signal swing handling. |
| IFM | 200 mA - Continuous forward current per diode; supports low-power logic-level clamping and auxiliary supply rectification. |
| VF @ 40 mA | ≤1000 mV - Low conduction loss at moderate load; reduces heat generation in space-constrained layouts. |
| trr | ≤5.0 ns - Fast recovery enables use in >20 MHz switching converters without excessive reverse recovery charge loss. |
| CT @ 0 V | 4.0–5.0 pF - Low junction capacitance preserves signal integrity in RF detector and high-speed data line clamping. |
| RθJA | 833 °C/W - Thermal resistance on FR-4 board; requires careful copper pour design to sustain full IFM at elevated ambient temperatures. |
Pinout & Package
SOT-563 is a 6-pin, 1.6 mm × 1.2 mm × 0.6 mm surface-mount plastic package with exposed thermal pad (non-electrical), matte tin-plated copper leadframe, and UL 94V-0 flammability rating. Moisture sensitivity level is J-STD-020 Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | Cathode of Diode 1 | Connected to negative side of first Schottky junction; routed to ground or return path in dual-rail clamping. |
| A2 | Anode of Diode 2 | Positive terminal of second diode; used for bidirectional signal limiting or independent rectifier input. |
| C2 | Cathode of Diode 2 | Independent cathode node; allows separate biasing or connection to different reference potentials. |
| A1 | Anode of Diode 1 | Primary input node for first diode; commonly tied to switched node in synchronous buck topologies. |
| NC | No Connect | Two pins (positions 3 and 6) are internally unconnected; must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Schottky diodes | Enables two separate clamping/rectification functions in one footprint-reduces PCB area vs. discrete SOD-323 devices. |
| PN junction guard ring | Provides robust ESD immunity (>8 kV HBM) and transient suppression without external TVS, simplifying surge-prone interface designs. |
| Low VF (380 mV typ. @ 1 mA) | Minimizes voltage drop in low-current bias networks and precision reference clamps where headroom is constrained. |
| RoHS + Halogen/Antimony-free | Fully compliant with EU Directive 2011/65/EU and green manufacturing standards (<900 ppm Br/Cl, <1000 ppm Sb). |
Applications
| USB Data Line Protection | Low-Power DC-DC Output Rectification |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines from ESD events and signal overshoot during hot-plug insertion. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting signal swing to ±0.3 V beyond VDD/VSS while preserving 480 Mbps data integrity. Use Value: Guard ring ensures >8 kV HBM ESD robustness without degrading signal rise/fall times due to low 4.5 pF CT. | Use Scenario: Freewheeling rectification in 3.3 V/5 V synchronous buck converters powering microcontrollers and sensors. IC Role / Device Role / Timing Role: Secondary-side Schottky diode replacing body diode of low-side MOSFET to reduce conduction loss during dead-time. Use Value: 380 mV VF at 10 mA lowers average power loss by >40% vs. standard silicon diodes, improving light-load efficiency. |
| RF Detector Input Clamping | Logic-Level Signal Translation |
Use Scenario: Front-end protection of 900 MHz RF envelope detectors against antenna coupling transients. IC Role / Device Role / Timing Role: AC-coupled shunt clamp limiting RF peak voltage to safe levels for downstream logarithmic amplifier inputs. Use Value: 5.0 ns trr and 4.5 pF CT prevent distortion of envelope shape and preserve detector dynamic range up to 100 MHz. | Use Scenario: Level-shifting 1.8 V GPIO signals to 3.3 V domains in mixed-voltage SoC interfaces. IC Role / Device Role / Timing Role: Anode-referenced clamp diode pulling signal high to 3.3 V − VF when driven low, enabling bidirectional translation. Use Value: Matched VF across dual diodes ensures consistent threshold offset (±10 mV) between channels for timing-critical I²C/SPI bus extension. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0540T1G | Single diode, SOD-123, 40 V/500 mA, VF = 450 mV @ 500 mA | Higher current rating but larger footprint and no dual-channel integration | Preferred when single high-current rectification is needed and board space permits larger package. |
| NSR0240HT1G | Dual diode, SOT-23-6, 40 V/200 mA, VF = 430 mV @ 100 mA, trr = 6 ns | Same electrical specs but larger SOT-23-6 footprint and slightly slower recovery | Used when legacy SOT-23-6 layout compatibility is required and 1 ns trr margin is acceptable. |
Compared with MBR0540T1G and NSR0240HT1G, the BAS40V-7 uniquely delivers dual-channel functionality in the smallest available footprint (SOT-563), lowest VF at microamp bias currents, and integrated guard ring-making it optimal for ultra-compact, ESD-sensitive, multi-rail clamping applications.

FAQ
What is the maximum junction temperature for BAS40V-7 during continuous operation?
The BAS40V-7 has a specified operating junction temperature range of −55 °C to +125 °C. At 200 mA forward current on a standard FR-4 board, junction temperature rise is limited to ≤105 °C above ambient due to its 833 °C/W RθJA and 150 mW power dissipation rating-ensuring reliable operation within industrial temperature limits.
Can BAS40V-7 be used in place of a single Schottky diode like 1N5819?
No-BAS40V-7 contains two independent Schottky diodes in one package and cannot substitute for a single-diode part without redesigning the circuit layout and signal routing. Its pinout (C1/A2/C2/A1/NC/NC) does not match any standard single-diode footprint, and using only one channel wastes board area and thermal performance potential.
Is the SOT-563 package thermally enhanced compared to SOT-23?
The SOT-563 package uses the same copper leadframe material as SOT-23 but features a smaller die pad area and thinner mold compound, resulting in higher thermal resistance (833 °C/W vs. ~400 °C/W for SOT-23). Effective thermal management requires optimized PCB copper pour under the exposed pad-even though that pad is non-electrical-and minimizing trace length to heat sinks.
Does BAS40V-7 meet automotive AEC-Q200 requirements?
No-BAS40V-7 is not qualified to AEC-Q200. It is rated for industrial temperature range (−55 °C to +125 °C) and carries no automotive stress test certification. For automotive applications, Diodes Incorporated offers the AEC-Q200-qualified BAS40DW-7 (dual Schottky in SOT-363), which shares similar electrical specs but undergoes extended temperature cycling, humidity bias, and mechanical shock validation.
