Product details
Overview
SBL6050PT from Diodes Incorporated is a 50V, 60A Schottky barrier rectifier in TO-3P package, featuring 0.70V forward voltage at 30A/25°C, 500A non-repetitive surge capability, and 0.5°C/W thermal resistance junction-to-case-designed for low-voltage, high-frequency inverters and polarity protection circuits.
For engineers reviewing the SBL6050PT datasheet, SBL6050PT pinout, SBL6050PT application, or SBL6050PT equivalent, key selection criteria include its 50V blocking rating, 60A average output current at TC = 100°C, low VFM for reduced conduction loss, guard ring die construction for transient robustness, and TO-3P mechanical compatibility with standard heatsink mounting.
Technical Context
This device operates as a single-diode Schottky rectifier with unidirectional conduction and no gate control. Its guard ring die structure enhances ruggedness against voltage transients, while the low forward voltage drop directly reduces power dissipation in high-current DC-DC and inverter freewheeling paths.
Thermal performance is defined by RθJC = 0.5°C/W when mounted on a heatsink, enabling sustained 60A operation at TC = 100°C. Capacitance is 1500pF at 1MHz/4V reverse bias-relevant for high-frequency switching noise and snubber design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in polarity protection and DC bus clamping |
| IO @ TC=100°C | 60 A - Continuous average forward current with heatsink; defines usable current capacity in power supply outputs |
| VFM @ IF=30A, 25°C | 0.70 V - Forward voltage drop at rated half-load; determines conduction loss (21W at 30A) |
| IFSM (8.3ms) | 500 A - Peak non-repetitive surge current; supports motor startup and capacitor-charging transients |
| RθJC | 0.5 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing for thermal management |
| CT @ 1MHz, 4V | 1500 pF - Junction capacitance; impacts high-frequency switching losses and EMI filter design |
Pinout & Package
TO-3P package: molded plastic case (UL 94V-0), 3-terminal configuration with anode, cathode, and metal tab (cathode-connected). Mounting hole centered on tab for heatsink attachment. Polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connects to lower-potential side (e.g., switch node in buck converter); carries full load current |
| Cathode (Lead 2) | Output terminal for forward conduction | Connects to higher-potential rail (e.g., output capacitor positive); electrically tied to metal tab |
| Metal Tab | Cathode connection & thermal path | Provides low-inductance cathode return and primary heat conduction path to heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity without external TVS, reducing system-level protection component count |
| Low forward voltage (0.70V @ 30A) | Minimizes conduction loss in high-current paths-critical for efficiency in 12V/24V industrial power supplies |
| High surge rating (500A IFSM) | Withstands repeated inrush events in motor drives and battery-charged systems without degradation |
| TO-3P mechanical form factor | Enables direct replacement of legacy rectifiers (e.g., MUR6060PT) with standardized heatsink interface |
Applications
| DC-DC Converter Output Rectification | Automotive Alternator Freewheeling |
|---|---|
Use Scenario: High-current synchronous rectifier replacement in 12V/48V isolated DC-DC modules for telecom and server PSUs. IC Role / Device Role / Timing Role: Uncontrolled Schottky rectifier providing low-loss unidirectional current path during freewheeling phase. Use Value: 0.70V VFM reduces conduction loss by ~35% vs. silicon diodes, improving full-load efficiency by 1.2–1.8%. | Use Scenario: Reverse-polarity protection and flyback energy recapture in 12V automotive alternators. IC Role / Device Role / Timing Role: Cathode-tied-to-chassis Schottky clamp preventing battery discharge through stator windings during engine-off. Use Value: 500A IFSM handles alternator field collapse surges; TO-3P tab ensures reliable chassis thermal coupling. |
| Solar Charge Controller Polarity Protection | Industrial AC-DC Front-End Rectification |
Use Scenario: Bidirectional polarity guard in off-grid solar charge controllers connecting PV array to battery bank. IC Role / Device Role / Timing Role: Anode-to-PV / cathode-to-battery configuration blocks reverse current during night or shading conditions. Use Value: 50V VRRM matches nominal 48V battery systems; 60A IO supports up to 3kW charge rates with minimal derating. | Use Scenario: Input-stage rectification in 3-phase industrial AC-DC converters feeding servo drives and PLC power rails. IC Role / Device Role / Timing Role: Single-phase, half-wave rectifier used in auxiliary supply or snubber clamp networks. Use Value: 0.5°C/W RθJC allows stable operation at 60A with passive heatsinking-eliminating need for forced air in enclosed cabinets. |
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-60CPH05 | Same 50V VRRM, 60A IO, but TO-247AC package; slightly higher VFM (0.72V) | Larger footprint, different mounting hole pattern; requires revised PCB layout and heatsink interface | Select if TO-247 heatsink infrastructure already exists and lead-time for SBL6050PT is constrained |
| ON Semiconductor MBR6050PT | Identical TO-3P package and pinout; VFM 0.71V at 30A, RθJC 0.55°C/W | Direct mechanical and electrical drop-in; minor thermal derating required above 95°C case temperature | Preferred for new designs requiring second-source availability without layout change |
Compared with VS-60CPH05 and MBR6050PT, the SBL6050PT offers the lowest thermal resistance (0.5°C/W) and tightest VFM tolerance among TO-3P 50V/60A Schottkys-making it optimal for thermally constrained, high-efficiency 12–48V power conversion where heatsink mass is limited.

FAQ
Is SBL6050PT RoHS compliant?
Yes, SBL6050PT features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC revision 13.2.2003, with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. The tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements.
What is the maximum operating temperature for SBL6050PT?
The SBL6050PT has a specified operating junction temperature range of –65°C to +150°C. Its 60A average current rating is valid only when case temperature (TC) is maintained at ≤100°C via appropriate heatsinking; exceeding this causes immediate current derating per Figure 1 in the datasheet.
Can SBL6050PT be used in parallel configurations?
Parallel operation is not recommended without individual current-sharing resistors or matched thermal mounting. The device exhibits negative temperature coefficient behavior-forward voltage decreases with rising temperature-which can cause current hogging and thermal runaway if paralleled directly on a common heatsink without balancing.
Does SBL6050PT have avalanche rating?
No, SBL6050PT is not avalanche-rated. As a Schottky rectifier, it lacks controlled avalanche capability. Transient overvoltage protection must be implemented externally using TVS diodes or RC snubbers-especially in inductive load switching applications where L·di/dt spikes may exceed 50V.
