Product details
Overview
SBR3U60SA-13 from Diodes Incorporated is a 3A, 60V Super Barrier Rectifier in SMA package, featuring 0.65V max forward voltage at 3A/25°C, ≤100μA reverse leakage at 60V/125°C, and thermal resistance RθJA of 81°C/W. It serves as a high-efficiency boost or recirculating diode in DC-DC converters and power supplies operating up to +150°C ambient.
For engineers reviewing the SBR3U60SA-13 datasheet, SBR3U60SA-13 pinout, SBR3U60SA-13 application, or SBR3U60SA-13 equivalent, this page delivers verified electrical specs, thermal derating behavior, low-VF advantage over Schottky diodes, and RoHS-compliant "Green" packaging details for industrial and automotive-grade power design validation.
Technical Context
The SBR3U60SA-13 uses a proprietary Super Barrier structure that achieves lower forward voltage than standard PN rectifiers while maintaining significantly better high-temperature reverse leakage stability than conventional Schottky diodes. Its 60V VRRM rating supports 48V system input rails with margin.
Designed for surface-mount operation on FR-4 PCBs with 0.2"×0.25" copper pads, it delivers 3A average rectified current with 60A non-repetitive surge capability (8.3ms half-sine), enabling robust transient handling in switching power stages without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Withstands 60V repetitive reverse voltage; suitable for 48V bus applications with safety margin. |
| IO | 3 A - Continuous average forward current at +25°C ambient on standard FR-4 layout. |
| VF max | 0.65 V @ 3A, +25°C - Enables higher efficiency than standard PN diodes; reduces conduction loss by ~30% vs. 1N5822. |
| IR max | 100 μA @ 60V, +125°C - Stable leakage under high-temp stress; avoids thermal runaway in enclosed enclosures. |
| RθJA | 81 °C/W - Junction-to-ambient thermal resistance on 0.4"×0.5", 2oz single-sided FR-4; informs heatsinking requirements. |
| TJ range | –55°C to +150°C - Full operational junction temperature range; qualified for under-hood automotive environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with cathode band marking. Dimensions: 4.60 × 2.92 × 1.63 mm (L × W × H). Matte tin–annealed copper leadframe, RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to source/switch node in boost or flyback topologies; handles full load current and surge peaks. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; blocks 60V reverse bias during off-state with minimal leakage. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier architecture | Combines low VF of Schottky with high-temperature IR stability of PN junctions-no trade-off between efficiency and reliability. |
| 0.65V VF max @ 3A/25°C | Reduces conduction loss by ≥0.4W vs. 1N5822 at same current, lowering thermal stress in compact layouts. |
| ≤100μA IR @ 60V/125°C | Enables stable operation in sealed, high-ambient-temperature environments without thermal runaway risk. |
| RoHS-compliant & Halogen-free | Meets EU Directive 2015/863/EU; <900ppm Br, <900ppm Cl, <1000ppm Sb-supports green manufacturing and end-of-life compliance. |
Applications
| Boost Converter Diode | Blocking Diode in Solar Charge Controller |
|---|---|
Use Scenario: Used in 48V-input isolated DC-DC boost stage delivering 12V/2A output. IC Role / Device Role / Timing Role: Unidirectional current path during MOSFET off-time; clamps inductive kickback and transfers stored energy. Use Value: 0.65V VF minimizes conduction loss across duty cycle; 60A IFSM withstands startup surges without degradation. | Use Scenario: Prevents battery backfeed into PV panel during night or shading conditions. IC Role / Device Role / Timing Role: Reverse-blocking element placed between panel output and battery terminal. Use Value: 100μA IR at 125°C ensures negligible nighttime discharge in hot-climate installations. |
| Recirculating Diode in Motor Driver | Output Rectifier in AC-DC Adapter |
Use Scenario: Freewheeling path for brushed DC motor current when H-bridge switches turn off. IC Role / Device Role / Timing Role: Provides low-loss current recirculation loop during PWM dead time. Use Value: Low VF reduces heat generation during continuous PWM operation; 150°C TJ rating supports sealed motor housings. | Use Scenario: Secondary-side rectification in 24V/3A wall adapter using flyback topology. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC output. Use Value: Stable 0.61V VF at 125°C maintains regulation accuracy across temperature; SMA footprint enables high-density layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT3U60SA-13 | Same die, enhanced surge rating: IFSM = 75A (vs. 60A); identical VF, IR, and package. | Preferred where repeated inrush or lightning-induced transients occur (e.g., outdoor PoE injectors). | Select SBRT3U60SA-13 if surge immunity >60A is required; otherwise SBR3U60SA-13 remains optimal for cost-sensitive designs. |
| MBR360F-TP | Standard Schottky; VF = 0.72V max @ 3A/25°C; IR = 500μA @ 60V/125°C - 5× higher leakage. | Acceptable only in cooled, low-ambient-temperature environments; not recommended for sealed enclosures above 85°C. | Choose MBR360F-TP only if board-level cooling ensures TA ≤ 75°C and leakage sensitivity is low. |
Compared with SBRT3U60SA-13 and MBR360F-TP, the SBR3U60SA-13 offers the best balance of low VF, ultra-low high-temp leakage, and cost-making it ideal for thermally constrained industrial power supplies where reliability trumps marginal surge headroom.

FAQ
Is SBR3U60SA-13 still in active production?
No-Diodes Incorporated has officially discontinued SBR3U60SA-13 (marked "OBSOLETE" in DS37416 Rev. 4). Aetrix Electronics holds remaining authorized inventory and supports legacy design continuity with full traceability and extended lifecycle coordination for existing programs.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C. Derating begins at +25°C ambient: IO drops linearly to zero at +150°C per Figure 5. At +100°C ambient, rated average current is ~1.8A on standard FR-4 layout with 0.2"×0.25" copper pad.
Can SBR3U60SA-13 replace a standard Schottky diode like 1N5822?
Yes-with key advantages: lower VF (0.65V vs. 0.9V) improves efficiency, and superior high-temperature leakage (<100μA vs. >1mA at 125°C) prevents thermal runaway. No layout change needed-SMA package matches 1N5822's DO-214AC footprint.
Does SBR3U60SA-13 meet AEC-Q101 for automotive use?
No-the datasheet states AEC-Q101 qualification requires specific change control and PPAP capability, which SBR3U60SA-13 does not carry. For automotive applications, Diodes recommends contacting their representative to evaluate qualified alternatives such as the AEC-Q101-certified SBRT3U60SQA series.
