Product details
Overview
SBR0220T5-7 from Diodes Incorporated is a 0.2A, 20V Super Barrier Rectifier in SOD-523 package, featuring 0.37V typical forward voltage at 0.1A/25°C, 150°C max junction temperature, and soft fast switching for low-noise DC/DC output rectification in space-constrained portable power supplies.
For engineers reviewing the SBR0220T5-7 datasheet, SBR0220T5-7 pinout, SBR0220T5-7 application, or SBR0220T5-7 equivalent, key selection criteria include forward voltage at 0.2A load, reverse leakage at 85°C, avalanche ruggedness, thermal resistance (400°C/W), and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
This discrete Schottky-derived rectifier uses patented Super Barrier technology to achieve lower VF than standard Schottkys while maintaining higher reverse breakdown and superior avalanche energy handling. It operates reliably up to 150°C junction temperature with no thermal runaway risk under transient overloads.
Designed for low-voltage, high-efficiency secondary-side rectification, it replaces conventional Schottky diodes where soft recovery reduces EMI in buck converter outputs and USB-powered devices. Its 0.002g mass and SOD-523 outline support ultra-thin wearable and hearing aid PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 20 V - Withstands full-rated blocking voltage without breakdown in 3.3V–5V rail applications |
| Forward Voltage (IF=0.2A) | 0.41 V @ 85°C - Enables <100mW conduction loss per diode in compact 5V USB-C PD adapters |
| Reverse Leakage (VR=20V) | 0.5 µA @ 25°C; 0.5 mA @ 85°C - Low standby current preserves battery life in always-on sensor nodes |
| Surge Current (IFSM) | 5 A (8.3ms half-sine) - Handles inrush during hot-plug events in portable chargers |
| Thermal Resistance | 400 °C/W - Requires minimal copper area (per AP02001 layout) for 0.2A continuous operation |
| Junction Temperature | -65°C to +150°C - Supports operation inside sealed enclosures without forced air cooling |
Pinout & Package

Applications
| USB Power Delivery Adapter | Wireless Earbud Charging Case |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 5V/9V/12V flyback converters delivering up to 20W. IC Role / Device Role / Timing Role: Low-VF rectifier replacing MOSFET gate drivers in cost-sensitive designs; conducts only during positive half-cycle. Use Value: 0.41V VF at 0.2A cuts conduction loss by ~30% vs. standard Schottky, extending adapter efficiency above 89% at light load. | Use Scenario: Output rectification in miniature 3.7V Li-ion charging circuits within sub-30mm² earbud case PCBs. IC Role / Device Role / Timing Role: Unidirectional current path from boost converter to battery; cathode tied to battery anode. Use Value: SOD-523 footprint saves >0.5mm² vs. SOD-123, enabling tighter component placement without sacrificing 5A surge rating. |
| Industrial Sensor Node | Medical Wearable Monitor |
Use Scenario: Input protection and reverse-polarity safeguard for 3.3V microcontroller power rails powered by coin-cell or energy-harvesting sources. IC Role / Device Role / Timing Role: Polarity guard diode placed before LDO input; blocks reverse current during battery swap or hot insertion. Use Value: 0.5µA leakage at 25°C prevents >1% monthly battery drain-critical for 10-year shelf-life deployments. | Use Scenario: Isolation and voltage clamping in ECG front-end analog supply paths operating at body temperature (37°C ambient, 55°C internal). IC Role / Device Role / Timing Role: Reverse-biased clamp limiting supply rail excursions during ESD events on patient-connected leads. Use Value: 150°C rating ensures stable 20V breakdown and <1mA leakage at elevated temperatures-no parameter drift across clinical operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBM0220T5-7 | Same SOD-523 package; 0.39V VF typ @ 0.2A/25°C; 3A IFSM (vs. 5A) | Limited surge margin in hot-plug USB-C applications | Prefer SBR0220T5-7 when 5A surge immunity is required for field-replaceable ports |
| NSR0220HT1G | 0.45V VF @ 0.2A/25°C; 300°C/W RθJA; same 20V VRRM | Higher thermal resistance requires larger pad for same current | Choose SBR0220T5-7 for tighter thermal design in sealed enclosures with limited airflow |
Compared with SBM0220T5-7 and NSR0220HT1G, the SBR0220T5-7 delivers superior surge robustness and lower thermal resistance-enabling smaller PCB area and higher reliability in portable power systems subject to repeated plug/unplug cycles and ambient temperature variation.

FAQ
What is the maximum continuous forward current rating for SBR0220T5-7 at 85°C ambient?
The device is rated for 0.2A average rectified output current at TA = 25°C. At 85°C ambient, derating follows Figure 4: maximum ambient temperature drops to ~110°C at 20V reverse bias, but current remains 0.2A if board layout meets AP02001 minimum pad requirements and junction temperature stays ≤150°C.
Does SBR0220T5-7 have avalanche energy rating specified in the datasheet?
Yes-the datasheet highlights "superior reverse avalanche capability" as a core feature. While no single joule value is tabulated, the 20V V(BR)R rating tested at 400µA and ability to withstand 5A non-repetitive surge confirm robust avalanche performance beyond standard Schottky diodes, validated per JEDEC JESD24-11.
Can SBR0220T5-7 be used in place of a standard Schottky diode like 1N5817?
No-it is not a drop-in replacement. The SBR0220T5-7 has lower VF (0.41V vs. ~0.45V) and higher ruggedness, but its SOD-523 package (1.6×0.8mm) differs mechanically from DO-41 or SOD-123 packages. Board redesign is required; electrical substitution is viable only after verifying layout thermal performance and surge margin.
Is the SOD-523 package of SBR0220T5-7 compatible with standard reflow profiles?
Yes-its Level 1 moisture sensitivity rating per J-STD-020D allows floor life unlimited at ≤30°C/60% RH. Standard lead-free reflow profiles (peak 260°C, 30 sec max) are supported; matte tin finish ensures solderability per MIL-STD-202 Method 208, and UL 94V-0 compound resists charring during thermal cycling.
