Product details
Overview
SBR2A40P1-7 from Diodes Incorporated is a 2 A, 40 V SBR Super Barrier Rectifier in a PowerDI123 package. It combines low forward voltage, low leakage, strong avalanche behavior, and compact thermal performance for efficient low-voltage power conversion.
For engineers reviewing the SBR2A40P1-7 datasheet, SBR2A40P1-7 pinout, SBR2A40P1-7 application, or SBR2A40P1-7 equivalent, this part is most relevant for DC-DC converters, freewheel paths, polarity protection, portable equipment, adapter outputs, industrial rails, and repair programs requiring 2 A rectification, 40 V blocking, 50 A surge capability, PowerDI123 assembly, and soft fast switching behavior.
Technical Context
SBR2A40P1-7 uses Diodes Incorporated SBR technology, which is intended to deliver Schottky-like low forward voltage with controlled leakage and strong high-temperature behavior. In low-voltage rails, the reduction in forward loss can directly reduce heat and improve converter efficiency.
The PowerDI123 package uses a compact layout with good current handling for its size. The part also includes high surge and reverse-avalanche capability, which is valuable in power paths exposed to startup stress, inductive energy, or switching-node transients.

Pinout & Package
SBR2A40P1-7 is a two-terminal PowerDI123 rectifier. The cathode band marks the output/blocking terminal, and the anode is the opposite side. The package is compact but handles meaningful current, so pad layout, copper area, and polarity inspection are important.
| Pin / Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward-current entry terminal. | Connects to the lower-potential side during conduction in converter or protection paths. |
| Cathode | Cathode-band forward-current exit terminal. | Connects to the protected, rectified, or output node and blocks reverse voltage. |
| PowerDI123 body | Compact thermal surface-mount package. | Provides low-profile assembly and heat spreading for 2 A SBR operation. |

Applications
| DC-DC Converter Output Paths | Freewheel and Recirculation |
|---|---|
|
Use Scenario: Low-voltage regulators where diode forward drop directly affects efficiency and thermal rise. Device Role: SBR2A40P1-7 acts as the rectifier or catch diode in the converter power stage. Use Value: Its low VF behavior reduces conduction loss while the SBR structure supports stable high-temperature operation. |
Use Scenario: Inductive loads or switching rails that need a current path when a switch turns off. Device Role: The device carries recirculating current and clamps switching-node energy within its ratings. Use Value: SBR2A40P1-7 combines 2 A capability, surge tolerance, and soft fast switching in a small package. |
| Polarity Protection | Compact Power Board Repair |
|
Use Scenario: Portable, industrial, or adapter-powered products where input polarity mistakes or rail OR-ing must be handled. Device Role: SBR rectifier used as a low-drop series or steering diode. Use Value: The low forward voltage preserves rail voltage better than a standard silicon rectifier. |
Use Scenario: Existing boards using PowerDI123 low-voltage rectifiers near hot or space-constrained areas. Device Role: Replacement-class 2 A, 40 V SBR diode where package and polarity match the layout. Use Value: SBR2A40P1-7 supports efficient repair or continuity planning for dense power modules. |
Equivalent & Alternatives
When evaluating SBR2A40P1-7 equivalent devices, compare SBR technology, reverse voltage, forward voltage at real load current, leakage at temperature, surge current, avalanche rating, PowerDI123 footprint, cathode band, and reel format.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBR2A40P1Q-7 | Automotive-oriented orderable version of the same 2 A, 40 V PowerDI123 SBR product family. | Useful where AEC-Q101 or automotive change-control sourcing is required. | Choose the Q version when the BOM calls for automotive qualification support; still check marking and approval status. |
| SBR2A30P1-7 | Related PowerDI123 SBR option with lower 30 V reverse-voltage rating. | Can suit lower-voltage rails where 40 V blocking margin is unnecessary. | Keep SBR2A40P1-7 when converter ringing or input tolerance requires the 40 V class. |
| SBR2A60P1-7 | Related PowerDI123 SBR option with higher 60 V reverse-voltage class where available in the approved supply chain. | May help designs that need extra reverse-voltage margin while retaining SBR behavior. | Compare forward voltage, leakage, approved status, and thermal performance before increasing the voltage grade. |
Quality
SBR2A40P1-7 should be sourced as original Diodes Incorporated SBR devices through traceable and controlled supply channels. Quality checks may include PowerDI123 package inspection, cathode-band review, reel label verification, solderability testing, forward-voltage screening at relevant current, reverse-leakage testing, surge-risk review, MSL handling review, and incoming inspection for compact power assemblies.
Availability
SBR2A40P1-7 is available at Aetrix Electronics and suitable for DC-DC converters, freewheel paths, polarity protection, portable electronics, adapter outputs, industrial rails, compact power modules, and repair programs requiring a 2 A, 40 V PowerDI123 SBR rectifier.

FAQ
What is SBR2A40P1-7 used for?
SBR2A40P1-7 is used for low-loss rectification, DC-DC converter catch paths, freewheeling, polarity protection, and compact power modules. The 2 A current class, 40 V rating, and low forward voltage make SBR2A40P1-7 useful in efficient low-voltage power designs.
What package does SBR2A40P1-7 use?
SBR2A40P1-7 uses the PowerDI123 surface-mount package. This compact package supports meaningful current handling for its size, but pad layout, copper area, cathode-band orientation, solder profile, and package temperature should be checked before using SBR2A40P1-7 near full load.
What is the forward voltage of SBR2A40P1-7?
SBR2A40P1-7 has a low forward-voltage characteristic, with a 0.50 V maximum value at 2 A and 25°C under pulsed test conditions. In real equipment, SBR2A40P1-7 power loss still depends on load current, duty cycle, and operating temperature.
How does SBR2A40P1-7 differ from an ordinary Schottky diode?
SBR2A40P1-7 uses Diodes Incorporated Super Barrier Rectifier technology, which targets low forward voltage, controlled leakage, high-temperature stability, and soft fast switching. This makes SBR2A40P1-7 attractive for power paths where efficiency and thermal behavior matter together.
What should be checked before replacing SBR2A40P1-7?
Before replacing SBR2A40P1-7, check reverse-voltage class, current rating, forward voltage, hot leakage, surge current, avalanche behavior, PowerDI123 footprint, cathode orientation, SBR technology requirement, thermal layout, MSL handling, reel format, and any automotive or customer approval requirements.
