Product details
Overview
SB560-B from Diodes Incorporated is a 5.0A, 60V Schottky barrier rectifier in DO-201AD package, featuring low forward voltage drop (0.67V @ 5.0A), 150A non-repetitive surge capability, and RoHS-compliant tin-plated leads - used for polarity protection and free-wheeling in DC-DC converters and AC/DC front-ends.
For engineers reviewing the SB560-B datasheet, SB560-B pinout, SB560-B application, or SB560-B equivalent, key selection criteria include forward voltage at rated current, thermal resistance (RJA = 25°C/W), peak reverse voltage rating, surge robustness, and DO-201AD mechanical compatibility with high-power PCB layouts.
Technical Context
This Schottky rectifier uses epitaxial construction with guard ring die design to suppress transient-induced failure and sustain repetitive 8.3ms half-sine surges up to 150A. Its low VF enables high-efficiency operation in 12–48V output stages where conduction loss dominates thermal budget.
Thermal performance is defined by junction-to-ambient resistance of 25°C/W (measured at 9.5mm lead length) and junction-to-lead resistance of 8°C/W, supporting continuous 5.0A operation under forced-air or moderate heatsink conditions at Tj ≤ 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 60 V - blocks up to 60V DC or peak AC reverse bias without breakdown in bridge or clamp configurations. |
| Forward Voltage | 0.67 V @ 5.0A - reduces conduction loss to ~3.35W at full load, critical for thermal management in compact power supplies. |
| Avg. Rectified Current | 5.0 A - sustained DC output current rating under resistive/inductive loads with proper derating above 75°C ambient. |
| Surge Current | 150 A (8.3ms) - withstands inrush and short-circuit transients in motor drives and SMPS startup sequences. |
| Junction Temp Range | –65°C to +125°C - supports industrial and automotive under-hood environments with validated reliability at max Tj. |
| Reverse Leakage | 0.5 mA @ 25°C, 25 µA @ 100°C - low IR ensures minimal standby power loss in battery-backed systems. |
| Thermal Resistance RJA | 25 °C/W - defines temperature rise above ambient per watt dissipated; measured with 9.5mm lead length on open bench. |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are bright tin-plated, solderable per MIL-STD-202 Method 208, and mounted in any orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to lower-potential side (e.g., switch node in buck converter); carries full load current during on-state. |
| Cathode | Output terminal for forward conduction | Marked with band; connects to higher-potential rail (e.g., output capacitor positive); defines polarity protection direction. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances transient immunity against ESD and line surges without external TVS, reducing BOM count in industrial power inputs. |
| Low VF (0.67V @ 5A) | Minimizes I²R losses in high-current paths, enabling smaller heatsinks or higher efficiency in 12V/24V DC-DC modules. |
| 150A surge rating | Supports reliable operation during cold cranking (automotive) or motor stall events without fuse coordination overhead. |
| RoHS-compliant finish | Bright tin plating meets EU Directive 2011/65/EU Annexes 5 & 7 exemptions for high-temp soldering and glass content. |
Applications
| DC-DC Converter Output Rectification | Automotive Power Supply Clamp |
|---|---|
Use Scenario: Secondary-side rectification in 12V/48V synchronous or asynchronous buck converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated DC output while blocking reverse current during switch off-time. Use Value: 0.67V VF cuts conduction loss by >30% vs. standard PN rectifiers, directly improving full-load efficiency by 1.2–1.8%. |
Use Scenario: Reverse polarity protection and load dump clamping in 12V vehicle electronics (ECUs, infotainment). IC Role / Device Role / Timing Role: Cathode-connected to battery positive; anode to system input - blocks reverse connection and clamps transients via low-impedance path. Use Value: 150A surge rating absorbs ISO 7637-2 Pulse 5a without degradation; DO-201AD axial form factor fits legacy automotive board cutouts. |
| AC/DC Adapter Free-Wheeling | Industrial Motor Drive Snubber |
Use Scenario: Free-wheeling path across relay coils or transformer secondaries in offline AC/DC adapters and power tools. IC Role / Device Role / Timing Role: Provides low-loss recirculation path for inductive kickback energy during MOSFET/IGBT turn-off. Use Value: Fast recovery (inherent to Schottky) eliminates reverse recovery charge, preventing shoot-through in half-bridge topologies. |
Use Scenario: Snubbing diode across IGBT collector-emitter in 3-phase VFDs handling 3–7.5kW motors. IC Role / Device Role / Timing Role: Absorbs inductive energy during switching transitions and limits dv/dt stress on power devices. Use Value: Epitaxial guard ring structure sustains repeated 100A+ surges without parameter drift, extending field lifetime beyond 10 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50SQ060NTRP | Same 60V VRRM, but TO-277 surface-mount package; VF = 0.65V @ 5A; RJA = 40°C/W (no leads). | Requires rework of PCB layout; unsuitable for through-hole retrofits or high-temperature lead-solder processes. | Select when space-constrained SMT assembly is prioritized over mechanical serviceability. |
| ON Semiconductor SB560-E3/54 | Identical DO-201AD package and electrical specs; same 0.67V VF, 150A IFSM, and RoHS compliance. | No functional difference; differs only in tape-and-reel packaging (1.2K) and traceability markings. | Choose for volume tape-and-reel procurement where automated placement is required. |
Compared with VS-50SQ060NTRP and SB560-E3/54, SB560-B offers proven axial-leaded mechanical robustness for manual assembly and field repair, lower thermal resistance than SMT alternatives, and direct drop-in replacement in legacy DO-201AD footprints without layout revision.

FAQ
What is the maximum junction temperature for continuous operation?
The SB560-B is rated for continuous operation with junction temperature up to +125°C. Derating begins above 75°C ambient per Figure 1; at 100°C ambient, maximum average forward current drops to approximately 3.2A for resistive loads with 9.5mm lead length.
Is SB560-B suitable for capacitive-input filter applications?
No - the datasheet explicitly requires 20% current derating for capacitive loads due to high peak charging currents. For such applications, use a higher-current-rated Schottky (e.g., SB860) or add inrush limiting to stay within the 5.0A average rating.
How does the guard ring die construction improve reliability?
The guard ring mitigates edge breakdown under high dv/dt or transient overvoltage by redistributing electric field stress away from the active junction periphery, reducing premature avalanche and enhancing long-term stability in noisy industrial environments.
Can SB560-B be substituted for SB540 in existing designs?
Yes, with verification of reverse voltage margin: SB560-B has 60V VRRM vs. SB540's 40V, offering 50% higher blocking capability. No changes to footprint or thermal design are needed, but ensure system-level reverse transients do not exceed 60V.
