Product details
Overview
MBR180S1-7 from Diodes Incorporated is a 1A, 80V surface-mount Schottky barrier rectifier in SOD123 package, featuring 0.80 V max forward voltage at 1.0 A and 5 µA max reverse leakage at 80 V and +25°C. It serves as a low-loss freewheeling or polarity protection diode in compact DC-DC converters and reverse battery protection circuits.
For engineers reviewing the MBR180S1-7 datasheet, MBR180S1-7 pinout, MBR180S1-7 application, or MBR180S1-7 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (RθJA = 275 °C/W), reverse leakage at elevated temperature, junction capacitance (20 pF @ 5 V), and SOD123 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during voltage spikes. Its low VF stems from optimized metal-semiconductor interface design, enabling conduction loss reduction in 12 V and 24 V input power stages.
Thermal performance is defined by RθJA = 275 °C/W on FR-4 with minimum pad layout and RθJC = 95 °C/W, supporting operation from –55°C to +175°C junction temperature. Junction capacitance remains stable at 20 pF (f = 1 MHz, VR = 5 V), critical for high-frequency switching noise control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - blocks up to 80 V repetitive reverse voltage without breakdown |
| IO | 1.0 A - continuous average forward current rating at TA = +25°C |
| VF (max) | 0.80 V @ IF = 1.0 A, TA = +25°C - limits conduction loss to ≤0.8 W per diode |
| IR (max) | 5 µA @ VR = 80 V, TA = +25°C - ensures minimal standby power loss in battery-critical systems |
| RθJA | 275 °C/W - defines thermal derating slope on standard FR-4 PCB with recommended copper pads |
| CT | 20 pF @ VR = 5 V, f = 1 MHz - determines high-frequency switching node ringing and EMI contribution |
| TJ Range | –55°C to +175°C - supports under-hood automotive and industrial ambient environments |
Pinout & Package
Package: SOD123 - surface-mount plastic package with cathode band marking, 0.01 g weight, UL 94V-0 molding compound, and matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling path |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to higher-potential rail (e.g., output capacitor positive or battery +) |
Key Features
| Feature | Design Value |
|---|---|
| Low VF (0.80 V max) | Reduces power dissipation by ≥30% vs. comparable PN rectifiers at 1 A, improving efficiency in 5–24 V DC-DC stages |
| Guard ring die construction | Enhances surge immunity against repetitive transients (e.g., load dump, inductive kickback) without external TVS |
| Very low IR at high temperature | 400 µA max @ VR = 80 V, TA = +125°C - maintains low standby loss in thermally stressed environments |
| SOD123 footprint | Enables <2.7 mm × 1.6 mm board area usage, ideal for space-constrained USB-C PD adapters and portable medical devices |
Applications
| AC-DC Adapter Secondary Rectification | Reverse Battery Protection |
|---|---|
Use Scenario: Secondary-side rectification in 5–12 V, 1–2 W offline flyback adapters powering IoT sensors or smart home hubs. IC Role / Device Role / Timing Role: Unidirectional current path replacing PN diode to minimize heat generation and improve light-load efficiency. Use Value: 0.80 V VF reduces conduction loss by 0.25 W vs. 1.05 V Si diode at 1 A, lowering thermal stress on compact PCBs. | Use Scenario: Polarity protection in 12 V automotive body control modules powered from vehicle battery. IC Role / Device Role / Timing Role: Series-connected anode-to-load cathode-to-battery+ configuration blocking reverse current during accidental battery reversal. Use Value: 5 µA IR at +25°C and 400 µA at +125°C ensures <1 µW standby loss, preserving battery life over 10-year service life. |
| DC-DC Converter Freewheeling Diode | O-Ring for Dual Supply Rails |
Use Scenario: Freewheeling path in 3.3 V/5 V synchronous buck converter for FPGA I/O banks requiring fast turn-off. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side MOSFET off-time, minimizing voltage overshoot. Use Value: 20 pF junction capacitance limits displacement current during switching edge, reducing EMI in 500 kHz–2 MHz designs. | Use Scenario: OR-ing two independent 5 V supplies (e.g., main + backup) feeding a single load in telecom shelf management. IC Role / Device Role / Timing Role: Anode tied to each supply, cathodes joined to common output - conducts only from higher-voltage source. Use Value: Low VF ensures ≤40 mV voltage drop between sources, enabling seamless switchover without brownout on load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS12 | VF = 0.95 V max @ 1 A; IR = 500 µA @ 80 V, +25°C; same SOD123 package | Higher conduction loss and leakage reduce suitability for thermally constrained or battery-backed systems | Select when cost sensitivity outweighs efficiency and leakage requirements |
| SB180 | VF = 0.85 V max @ 1 A; IR = 10 µA @ 80 V, +25°C; SMC package (larger footprint, lower RθJA = 65 °C/W) | Superior thermal performance but incompatible with SOD123-restricted layouts; requires rework of PCB land pattern | Select only if board space allows SMC and thermal margin is insufficient with MBR180S1-7 |
Compared with SS12 and SB180, the MBR180S1-7 delivers the lowest VF among SOD123-packaged 1A/80V Schottkys while maintaining ultra-low leakage-making it optimal for space-constrained, efficiency-critical 12 V and 24 V power rails where thermal budget is tight but footprint cannot be enlarged.

FAQ
What is the maximum junction temperature rating for MBR180S1-7?
The MBR180S1-7 has a specified operating junction temperature range of –55°C to +175°C. This rating is validated per JEDEC standards and enables use in under-hood automotive locations and industrial environments where ambient temperatures exceed 105°C. Derating curves in the datasheet define safe current limits above +25°C ambient.
Does MBR180S1-7 meet AEC-Q101 qualification requirements?
The MBR180S1-7 is not AEC-Q101 qualified. Diodes offers AEC-Q101 versions under separate part numbers (e.g., MBR180S1Q-7). This standard part is intended for commercial and industrial applications; automotive-grade variants require explicit qualification documentation and PPAP submission.
Can MBR180S1-7 replace a 1N5819 in existing SOD123 designs?
Yes-MBR180S1-7 is a direct SOD123 footprint replacement for 1N5819 with identical pinout and polarity marking. It improves upon 1N5819's typical VF (0.475 V vs. 0.55 V at 1 A) and lowers IR (5 µA vs. 1000 µA at 80 V), delivering measurable efficiency and leakage gains without layout change.
What is the moisture sensitivity level (MSL) for MBR180S1-7?
The MBR180S1-7 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and does not require dry pack or baking prior to reflow soldering. This simplifies assembly logistics and eliminates moisture-related popcorning risk during standard Pb-free reflow profiles.
