Product details
Overview
MBR230S1F-7 from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in SOD123F package, rated for 30V peak repetitive reverse voltage, with max forward voltage of 0.42V at 2A/25°C and max leakage current of 1.0mA at 30V/25°C. It serves as a low-loss freewheeling or polarity protection diode in space-constrained DC-DC converters and battery-powered systems.
For engineers reviewing the MBR230S1F-7 datasheet, MBR230S1F-7 pinout, MBR230S1F-7 application, or MBR230S1F-7 equivalent, key selection criteria include forward voltage drop at 2A, thermal resistance (RθJA = 120°C/W), reverse leakage at elevated temperature, SOD123F footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during inductive switching events. Its low VF (0.32–0.42V) directly reduces conduction loss in high-frequency buck or boost stages where duty cycles demand minimal forward drop.
Designed for surface-mount operation on FR-4 PCBs with minimum pad layout per AP02001, it delivers 0.84W total power dissipation at 25°C ambient and supports continuous operation from –55°C to +125°C junction temperature, enabling use in thermally demanding industrial and automotive environments.

Applications
| AC-DC Adapter Rectification | Reverse Battery Protection |
|---|---|
Use Scenario: Secondary-side rectification in compact 5–12V wall adapters with high-frequency flyback topology. IC Role / Device Role / Timing Role: Schottky rectifier replacing synchronous MOSFET or PN diode to minimize conduction loss and improve light-load efficiency. Use Value: 0.42V VF at 2A cuts diode power loss by ~0.3W vs. 0.7V PN diode, reducing thermal stress on small PCBs. | Use Scenario: Preventing damage when a 12V automotive battery is connected with reversed polarity to an infotainment module. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-system rail; conducts only during correct polarity. Use Value: 1.0mA IR at 25°C ensures <12µW standby loss, preserving microamp-level sleep current budgets. |
| DC-DC Buck Converter Freewheeling | Multi-Supply "O-Ring" Protection |
Use Scenario: Freewheeling path in 3.3V/2A step-down converter driving FPGA I/O banks with fast transient loads. IC Role / Device Role / Timing Role: Provides low-VF return path during high-side MOSFET off-time; handles 2A peak inductor current. Use Value: 75pF capacitance minimizes ringing in 500kHz–1MHz switching nodes, easing EMI filter design. | Use Scenario: Isolating redundant 5V supplies in industrial PLC backplanes to prevent backfeeding between rails. IC Role / Device Role / Timing Role: Anode tied to each supply, cathodes joined to common load; conducts only from highest-voltage source. Use Value: 30V VRRM supports headroom for 5V ±10% tolerance plus ripple, ensuring reliable blocking of lower rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/54 (Vishay) | Same 30V/2A rating but SOD-123 package (not SOD123F); RθJA = 130°C/W; no AEC-Q101 qualification | Lacks automotive qualification; slightly larger thermal resistance limits high-ambient use | Preferred for cost-sensitive consumer designs where AEC-Q101 is not required |
| SS23 (ON Semiconductor) | 30V/2A, SOD-123 package; VF = 0.5V max @ 2A; IR = 0.5mA max @ 25°C; no AEC-Q101 | Higher VF increases conduction loss; lower IR benefits ultra-low-power systems | Chosen when leakage is prioritized over forward loss, e.g., energy-harvesting sensor nodes |
Compared with SB230-E3/54 and SS23, the MBR230S1F-7 offers the lowest VF (0.42V max) and AEC-Q101 qualification-making it optimal for thermally constrained automotive and industrial DC-DC designs where efficiency and reliability are jointly critical.

FAQ
What is the maximum junction temperature for continuous operation?
The MBR230S1F-7 supports continuous operation up to +125°C junction temperature, verified per AEC-Q101 thermal cycling and high-temperature reverse bias tests. Derating begins above 25°C ambient per Figure 5, with full 2.0A IO maintained only below 75°C ambient on standard FR-4 with recommended pad layout.
Is the SOD123F package compatible with standard SOD-123 reflow profiles?
Yes-the SOD123F is dimensionally identical to JEDEC-standard SOD-123 and uses the same matte tin finish on copper leadframe. It complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and withstands standard lead-free reflow profiles up to 260°C peak.
How does the guard ring construction improve reliability?
The guard ring die structure prevents premature edge breakdown during voltage transients by redistributing electric field concentration away from the silicon periphery. This enables reliable operation during 30A IFSM surges and extends lifetime in inductive switching applications like motor drivers and solenoid controls.
Can this diode replace a PN rectifier in an existing 24V DC-DC design?
Yes-its 30V VRRM provides sufficient margin for 24V nominal rails with ripple and transients. Substituting it for a 1N5819-type PN diode reduces forward drop by ~0.3V at 2A, cutting conduction loss by ~0.6W and lowering thermal rise by ~70°C on equivalent PCB area.
