Product details
Overview
SBL560 from Diodes Incorporated is a 5.0A, 60V Schottky barrier rectifier in TO-220AC package, designed for low-voltage, high-frequency power conversion. It delivers 0.70V forward voltage at 5.0A and 25°C, supports 175A non-repetitive surge current, and features guard ring die construction for transient protection-used in DC-DC converter freewheeling paths and polarity protection circuits.
For engineers reviewing the SBL560 datasheet, SBL560 pinout, SBL560 application, or SBL560 equivalent, key selection criteria include its 60V VRRM rating, 3°C/W thermal resistance (junction-to-case), 500pF junction capacitance at 4V, and TO-220AC mechanical compatibility with standard heatsinks in industrial power supplies.
Technical Context
The SBL560 operates as a single-element unidirectional Schottky rectifier with metal-semiconductor junction architecture, enabling low forward conduction loss and fast switching recovery without minority-carrier storage delay. Its guard ring structure enhances ruggedness against voltage transients during inductive load commutation.
Rated for 5.0A average forward current at TC = 95°C, it requires heatsinking per its 3°C/W RθJC specification and derates linearly above that temperature. The device is not rated for capacitive-load operation without 20% current derating per datasheet guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC blocking in 48V system inputs. |
| IF(AV) | 5.0 A @ TC = 95°C - Continuous forward current capability when mounted on heatsink; defines minimum heatsink requirement. |
| VFM | 0.70 V @ IF = 5.0A, TC = 25°C - Forward drop directly impacts conduction loss (3.5W at 5A) and thermal design margin. |
| IFSM | 175 A (8.3ms half-sine) - Surge rating determines robustness against inrush or fault currents in motor drives and SMPS startup. |
| RθJC | 3 °C/W - Thermal resistance from junction to case; enables calculation of junction temperature rise over heatsink base temperature. |
| Cj | 500 pF @ VR = 4V, 1MHz - Junction capacitance affects high-frequency switching noise and EMI filter design in >100kHz converters. |
| IRM | 33 mA @ TC = 100°C, VR = 60V - High-temperature leakage current influences standby power loss and thermal runaway risk in parallel configurations. |
Pinout & Package
Package: TO-220AC - Molded plastic case with integral metal tab (Pin 1), UL 94V-0 rated, tin-plated terminals, 2.3g mass. Mounting hole centered on tab for heatsink screw attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Anode | Electrically connected to semiconductor die anode; serves as primary thermal path and must be electrically isolated from chassis unless circuit topology permits common-anode configuration. |
| Pin 2 | Cathode | Standard cathode terminal; carries full load current to return path; layout must minimize loop inductance for high di/dt applications like synchronous rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity during inductive switching events, reducing risk of avalanche-induced failure in flyback snubbers. |
| Low VFM (0.70V @ 5A) | Reduces conduction loss by ~30% vs. comparable 60V silicon rectifiers, lowering thermal stress in compact 5–12V output supplies. |
| High IFSM (175A) | Enables reliable operation under short-duration overload conditions such as motor stall or capacitor precharge surges. |
| TO-220AC mechanical standardization | Ensures drop-in replacement compatibility with existing heatsink footprints and mounting hardware across legacy power designs. |
Applications
| DC-DC Converter Freewheeling | 48V Input Polarity Protection |
|---|---|
Use Scenario: Used as freewheeling diode in 12V/5V buck converter secondary side with 200kHz switching frequency. IC Role / Device Role / Timing Role: Unidirectional current path during low-side switch off-time; no timing function but critical for energy transfer continuity. Use Value: 0.70V VFM minimizes power loss during 5A peak inductor current, improving efficiency by ~1.2% over Si alternatives at full load. |
Use Scenario: Placed in series with 48V input rail to prevent damage from reverse battery connection in telecom power modules. IC Role / Device Role / Timing Role: Passive polarity enforcement element; conducts only when input polarity is correct. Use Value: 60V VRRM provides 20% margin above 48V nominal, while 5A rating supports up to 240W protected input power. |
| Industrial Motor Drive Snubber | LED Driver Output Rectification |
Use Scenario: Mounted across relay coil or brushed DC motor terminals to suppress inductive kickback spikes. IC Role / Device Role / Timing Role: Transient energy clamp; activated only during switch-off edge, not during steady-state conduction. Use Value: Guard ring structure withstands repetitive 100V+ transients without degradation, extending system reliability beyond 100k cycles. |
Use Scenario: Output rectifier in constant-current LED driver supplying 350mA to 10-series white LEDs (35V total). IC Role / Device Role / Timing Role: AC-to-DC conversion stage; conducts during positive half-cycles of transformer secondary. Use Value: 500pF Cj limits high-frequency ringing, reducing EMI emissions near 30MHz band without added RC snubbers. |

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design and manufacturing operations across Asia and the US.
The SBL5xx series belongs to Diodes' high-current Schottky rectifier product line, engineered specifically for efficiency-critical 5–48V power conversion where low VFM and high surge tolerance are mandatory.
FAQ
Is SBL560 still in active production?
No. Per Diodes Incorporated's August 2015 datasheet revision, SBL560 is marked "OBSOLETE – PART DISCONTINUED" with no alternate part offered. Aetrix Electronics stocks remaining authorized inventory sourced directly from Diodes' end-of-life channels with full traceability and date-code verification.
Can SBL560 be used in surface-mount designs?
No. SBL560 uses the through-hole TO-220AC package with integral metal tab and two leads. It is incompatible with SMT reflow or wave soldering processes. No SMD variant (e.g., D2PAK or PowerDI5) exists in the SBL5xx family per official Diodes documentation.
What is the maximum operating temperature for SBL560?
The absolute maximum junction temperature is +150°C, and the storage temperature range is –65°C to +150°C. For continuous operation, the case temperature must not exceed +95°C at 5.0A average current, as defined by its derating curve and RθJC = 3°C/W specification.
Does SBL560 require thermal compound when mounted to a heatsink?
Yes. Because the TO-220AC metal tab (Pin 1/anode) serves as the primary thermal path, electrically insulating thermal interface material-such as silicone-based grease or ceramic-filled pads-is required between tab and heatsink to maintain electrical isolation while minimizing thermal resistance.
