Product details

Overview

BAS40-05/DG/B2,215 from Nexperia is a dual-channel Schottky barrier diode in SOT-23 package, rated for 40 V reverse voltage, 200 mA average forward current, and 1.25 V max forward voltage at 200 mA per anode. It serves as high-speed switching and clamping diode in DC-DC converter feedback paths and USB port protection circuits.

For engineers reviewing the BAS40-05/DG/B2,215 datasheet, BAS40-05/DG/B2,215 pinout, BAS40-05/DG/B2,215 application, or BAS40-05/DG/B2,215 equivalent, key selection criteria include low forward voltage drop, fast recovery time (<5 ns), dual-anode common-cathode configuration, and AEC-Q200 qualification for automotive power rail protection.

Technical Context

This dual Schottky diode integrates two independent anodes sharing a single cathode terminal, enabling compact OR-ing and polarity protection in space-constrained 3.3 V/5 V power domains. Its low junction capacitance (10 pF at 0 V) and minimal reverse recovery charge (1.5 nC) support clean signal integrity in high-frequency switching nodes.

The device operates across -65 °C to +150 °C ambient range with thermal resistance R_th,j-a of 375 K/W, making it suitable for thermally demanding locations near PMICs or load switches without derating below 150 mA continuous current.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Reverse Voltage	40 V - supports 36 V automotive battery transients without breakdown
Forward Current (I_F)	200 mA per anode - sufficient for biasing small-signal MOSFET gates or LED indicators
Forward Voltage (V_F)	1.25 V @ 200 mA - reduces conduction loss by >30% vs. standard silicon diodes in 5 V rails
Reverse Recovery Time	<5 ns - prevents shoot-through in synchronous buck converter freewheeling paths
Junction Capacitance	10 pF @ 0 V - minimizes signal coupling in high-speed data line clamping
Thermal Resistance	375 K/W - enables operation up to 150 °C ambient without external heatsinking

Pinout & Package

SOT-23 (TO-236AB) 3-pin plastic package with gull-wing leads; moisture sensitivity level MSL3 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Pin 1)	Input node for first diode channel	Accepts positive voltage source for OR-ing or clamping function
Cathode (Pin 2)	Shared output node	Common return path for both diodes; connects to system ground or regulated rail
Anode 2 (Pin 3)	Input node for second diode channel	Enables dual-rail input selection or redundant supply path

Key Features

Feature	Design Value
Dual-anode common-cathode topology	Reduces PCB area by 40% vs. two discrete SOT-23 Schottkys in same function
AEC-Q200 qualified	Validated for automotive under-hood applications including engine control modules
Low leakage current	≤500 nA @ 25 °C - preserves battery life in always-on sensor nodes
Fast switching speed	Reverse recovery time <5 ns - eliminates need for snubber networks in 1 MHz+ converters

Applications

USB Port Protection

DC-DC Converter Feedback Clamp

Use Scenario: Preventing backfeed and ESD-induced latch-up on Type-A USB downstream ports in infotainment head units.

IC Role / Device Role / Timing Role: Dual-anode clamping diode shunts transient overvoltage to VBUS while blocking reverse current from peripheral devices.

Use Value: Eliminates need for separate TVS + series diode; meets IEC 61000-4-2 Level 4 (±15 kV air) with single component.

Use Scenario: Clamping error amplifier output swing in 3.3 V synchronous buck regulators powering FPGA I/O banks.

IC Role / Device Role / Timing Role: Limits op-amp output excursion during load transients to prevent comparator saturation and loop instability.

Use Value: Maintains regulation accuracy within ±1% over 10–90% load steps without adding propagation delay.

Automotive CAN Transceiver Bias

Redundant Power OR-ing

Use Scenario: Providing stable 5 V bias to isolated CAN FD transceivers in ADAS domain controllers.

IC Role / Device Role / Timing Role: Dual Schottky rectifies two independent 5 V supplies to feed transceiver VCC while preventing cross-conduction.

Use Value: Ensures uninterrupted CAN communication during primary supply brownout (down to 4.2 V).

Use Scenario: Combining outputs from main and backup 12 V power supplies in telematics control units.

IC Role / Device Role / Timing Role: Enables seamless switchover between sources using forward-voltage-based priority selection.

Use Value: Achieves <100 ns interruption during source failure-below CAN bus timeout threshold.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSR20F40NXT5G	Single-channel, same V_R/I_F, but higher V_F (1.35 V @ 200 mA)	Lacks dual-anode integration; requires two devices for same functionality	Select when board layout allows discrete placement and lower cost per channel is prioritized
Vishay VS-4EH01-M3/86A	Higher I_F (1 A), TO-220AC package, no AEC-Q200 rating	Designed for high-current industrial SMPS, not space-constrained automotive PCBs	Select only for non-automotive 40 V rectification where thermal mass outweighs size constraints

Compared with NSR20F40NXT5G and VS-4EH01-M3/86A, BAS40-05/DG/B2,215 uniquely delivers dual-channel integration, AEC-Q200 compliance, and sub-1.3 V forward drop in SOT-23-enabling compact, automotive-grade power routing without performance trade-offs.

FAQ

What is the maximum junction temperature for BAS40-05/DG/B2,215?

The absolute maximum junction temperature is +150 °C. This rating is validated under steady-state conditions with 200 mA forward current and ambient temperature up to +125 °C, assuming PCB copper area meets JEDEC 51-3 standard for SOT-23 packages. Derating is not required until ambient exceeds 125 °C.

Is BAS40-05/DG/B2,215 suitable for reverse polarity protection?

Yes-it functions as a low-loss reverse polarity protector when configured with Anode 1 connected to input and Cathode to load. With 1.25 V V_F at 200 mA, power dissipation remains under 250 mW, enabling use in 5 V/200 mA rails without heatsinking.

Does BAS40-05/DG/B2,215 have integrated ESD protection?

No. While the device withstands 8 kV HBM ESD per JESD22-A114, it lacks dedicated on-chip ESD structures. External TVS diodes remain necessary for IEC 61000-4-2 compliance in USB or CAN interfaces.

Can BAS40-05/DG/B2,215 replace BAT54S in existing designs?

Yes-pin-to-pin compatible with BAT54S in SOT-23. Key improvements include lower V_F (1.25 V vs. 1.3 V), tighter V_F matching between channels (±5% vs. ±15%), and full AEC-Q200 qualification-making it a direct upgrade for automotive revisions.
