Product details
Overview
MBR0580S1-7 from Diodes Incorporated is a 0.5A, 80V surface-mount Schottky barrier rectifier in SOD123 package, featuring VF ≤ 0.80 V at 0.5A/25°C, IR ≤ 5 µA at 80V/25°C, and TJ = −55°C to +175°C operation. It serves as low-loss freewheeling or reverse-polarity protection diode in space-constrained DC-DC converters and battery-powered systems.
For engineers reviewing the MBR0580S1-7 datasheet, MBR0580S1-7 pinout, MBR0580S1-7 application, or MBR0580S1-7 equivalent, key selection criteria include forward voltage drop at 0.5A, thermal resistance (RθJA = 200°C/W on 1-inch² Cu pad), reverse leakage at elevated temperature, and SOD123 mechanical compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness without compromising low VF performance. Its junction capacitance is 15 pF at 5V reverse bias and 1 MHz, enabling stable high-frequency switching behavior in buck converter output stages.
The device operates across −55°C to +175°C junction temperature range with derated reverse voltage above 100°C (Figure 4), and exhibits 14 A non-repetitive surge capability (8.3 ms half-sine) - critical for handling inrush and fault transients in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC blocking in 48V or 36V rail protection. |
| IO | 0.5 A - Continuous average forward current at TA = +25°C on FR-4 with 1-inch² Cu pad; defines steady-state power delivery capacity. |
| VF (max) | 0.80 V @ 0.5A, 25°C - Directly determines conduction loss (0.4 W max at full load); enables >92% efficiency in low-voltage synchronous rectifier alternatives. |
| IR (max) | 5 µA @ 80V, 25°C - Low leakage preserves battery hold-up time in reverse-battery protection circuits; rises to 280 µA at +125°C. |
| RθJA | 200 °C/W - Measured on FR-4 with 1-inch² Cu pad; enables ~213 mW max power dissipation before reaching 175°C junction limit. |
| TJ Range | −55°C to +175°C - Supports under-hood automotive, industrial motor control, and wide-temperature IoT edge nodes without derating. |
Pinout & Package
Package: SOD123 - Surface-mount plastic case (1.55 mm × 2.65 mm × 1.05 mm), matte tin-plated copper leadframe, cathode band marking, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter or battery negative in reverse protection). |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or system ground; blocks reverse current when anode is < cathode by >80V. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 0.69 V typ @ 0.5A/25°C - Reduces conduction loss by ≥40% vs. comparable PN rectifiers, lowering thermal stress in sealed enclosures. |
| Guard ring die construction | Enhanced ESD and transient immunity - Withstands repetitive 14 A surge without parametric shift, improving field reliability in noisy DC-DC environments. |
| SOD123 footprint | 1.55 mm × 2.65 mm body - Fits 2.0 mm × 3.0 mm PCB pad area; enables >30% board space reduction vs. SMA packages in multi-rail PMIC layouts. |
| Lead-free & Green compliance | Halogen- and antimony-free (<900 ppm Br+Cl, <1000 ppm Sb); UL 94V-0 molding compound - Meets IPC-JSTD-020 and automotive AEC-Q200 process requirements. |
Applications
| AC-DC Adapter Output Rectification | Reverse Battery Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 5–12 V, 0.5 A wall adapters using flyback topology. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; clamps transformer leakage energy. Use Value: 0.80 V VF minimizes 400 mW conduction loss at full load, reducing heatsink need and enabling ultra-thin adapter designs. |
Use Scenario: Preventing damage when Li-ion battery is inserted backward into portable medical monitor. IC Role / Device Role / Timing Role: Series-blocking diode placed between battery connector and system input rail. Use Value: 5 µA IR at 25°C extends shelf life >12 months; 280 µA at 125°C maintains safe cutoff in hot ambient conditions. |
| Multi-Rail "O-Ring" Protection | DC-DC Converter Freewheeling |
|
Use Scenario: Isolating 3.3 V, 5 V, and 12 V supply domains in FPGA-based test equipment to prevent backfeed. IC Role / Device Role / Timing Role: Unidirectional isolation element ensuring only forward current flows between rails. Use Value: 80 V VRRM supports simultaneous use across all three rails; SOD123 size allows placement adjacent to each LDO input. |
Use Scenario: Freewheeling path in 1 MHz, 12 V → 3.3 V buck converter powering Ethernet PHY. IC Role / Device Role / Timing Role: Provides low-loss return path during high-side switch off-time; complements synchronous FET. Use Value: 15 pF CT minimizes switching node ringing; fast recovery eliminates tail current, improving light-load efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS14 (Diodes Inc.) | Same SOD123 package; higher IO = 1.0 A, VF = 0.5 V max @ 1.0 A - but larger die increases capacitance (30 pF) and leakage (10 µA). | Better for 1 A continuous loads; less suitable where layout space or high-frequency noise is constrained. | Select SS14 only if current demand exceeds 0.5 A and board area permits trade-off in EMI margin. |
| SBM0580 (ROHM) | Identical 80 V / 0.5 A rating; VF = 0.75 V max @ 0.5 A; RθJA = 220 °C/W - slightly higher thermal resistance limits power density. | Valid drop-in for RoHS-compliant industrial programs already qualified on ROHM platforms. | Prefer MBR0580S1-7 where thermal headroom is tight or leakage-critical battery backup is required. |
Compared with SS14 and SBM0580, the MBR0580S1-7 delivers optimal balance of low VF (0.80 V), minimal leakage (5 µA), and proven thermal performance (200 °C/W) in the smallest SOD123 footprint - making it preferred for miniaturized, thermally isolated, or battery-sensitive designs.

FAQ
Is MBR0580S1-7 suitable for automotive under-hood applications?
Yes - its −55°C to +175°C operating junction temperature range, AEC-Q200-compatible construction (lead-free, halogen-free, 94V-0 mold compound), and 14 A surge rating meet requirements for engine control module auxiliary supplies and infotainment power rails, provided board-level thermal design maintains TJ ≤ 175°C.
What is the recommended PCB pad layout for MBR0580S1-7?
Diodes specifies a minimum 1-inch² copper pad for RθJA = 200°C/W testing. Recommended pad dimensions per SOD123 outline: 1.8 mm × 2.8 mm (length × width), with 0.3 mm solder mask opening and thermal relief spokes to inner layers. Full details are in package outline DS37435 Rev. 5-2, page 5.
Does MBR0580S1-7 have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, it has no minority-carrier storage and therefore no defined trr. Its switching is majority-carrier dominated, resulting in effectively zero reverse recovery charge (Qrr ≈ 0), eliminating switching losses and EMI associated with PN diode recovery tails.
Can MBR0580S1-7 replace a 1N5819 in existing designs?
Yes - both are 1 A / 40 V Schottky diodes, but MBR0580S1-7 offers higher VRRM (80 V vs. 40 V), lower IO (0.5 A vs. 1 A), and SOD123 (vs. DO-41) packaging. It is a direct replacement only if voltage margin >40 V is needed and current remains ≤0.5 A; board layout must accommodate SOD123 footprint.
