Product details
Overview
SBR10120CTL-13 from Diodes Incorporated is a 10A dual common-cathode super barrier rectifier in TO252 package, rated for 120V peak reverse voltage, with VF ≤ 0.88 V at 5A/25°C and IR ≤ 0.1 mA at 120V/25°C, used in high-efficiency DC/DC converter secondary-side rectification.
For engineers reviewing the SBR10120CTL-13 datasheet, SBR10120CTL-13 pinout, SBR10120CTL-13 application, or SBR10120CTL-13 equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance (RθJC = 20°C/W), surge current rating (IFSM = 110A), and RoHS-compliant matte tin terminal finish.
Technical Context
This device integrates two independent 120V/5A rectifying elements sharing a common cathode terminal, enabling synchronous-like efficiency in center-tapped transformer or dual-output flyback topologies without gate drive complexity. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to reduce forward conduction loss while maintaining low leakage.
Thermal performance is optimized for surface-mount PCB mounting on double-sided 125 mm² copper pads, supporting continuous 10A total output current when both legs operate in parallel under forced-air or moderate heatsinking conditions. Soft recovery minimizes EMI generation during turn-off in high-frequency switching converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in AC line or transformer secondary applications. |
| IO (per leg) | 5 A - Continuous average forward current per diode element at 25°C ambient; supports 10A total dual-leg output in common-cathode configuration. |
| VF @ 5A, 25°C | ≤ 0.88 V - Low conduction loss enables >92% efficiency in 12V-output DC/DC converters at full load. |
| RθJC | 20 °C/W - Junction-to-case thermal resistance measured on polyimide substrate; enables direct thermal coupling to heatsinked PCB ground plane. |
| IFSM | 110 A - Non-repetitive surge current capability for handling inrush or transient overload without degradation. |
| IR @ 120V, 25°C | ≤ 0.1 mA - Low reverse leakage preserves standby power budget in energy-sensitive applications like IoT power supplies. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-ended heat sink tab (pin 2), molded plastic case rated UL 94V-0, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first rectifying leg; connects to transformer secondary winding or switching node. |
| 2 | Cathode (common) | Shared output node for both diodes; electrically tied to PCB thermal pad for low-inductance, high-current return path. |
| 3 | Anode 2 | Input terminal for second rectifying leg; enables dual-output or center-tapped transformer rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Super barrier technology | Replaces PN junction with low-barrier metal-semiconductor interface to achieve VF reduction vs. Schottky while retaining higher VRRM than standard Schottky. |
| Soft, fast switching | Controlled reverse recovery (no hard snap-off) limits EMI generation and reduces snubber losses in 100–500 kHz SMPS designs. |
| High-temperature stability | VF increases only marginally from 0.88 V @ 25°C to 0.74 V @ 125°C; leakage remains ≤20 µA up to 175°C junction temperature. |
| RoHS-compliant matte tin finish | Lead-free, solderable per MIL-STD-202 Method 208; eliminates post-soldering cleaning and supports lead-free reflow profiles. |
Applications
| Server VRM Output Stage | Industrial DC/DC Converter |
|---|---|
Use Scenario: Secondary-side rectification in multiphase buck converters supplying CPU core voltage (0.8–1.2V @ up to 200A). IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys to reduce conduction loss and PCB footprint. Use Value: 0.88 V VF at 5A lowers power dissipation by ~1.2W per leg vs. comparable 100V Schottky, improving thermal margin in dense VRM layouts. | Use Scenario: Isolated 24V-to-5V/3.3V dual-output flyback supply for PLC I/O modules. IC Role / Device Role / Timing Role: Common-cathode dual rectifier delivering independent regulated outputs from single transformer secondary winding. Use Value: Shared cathode simplifies output filtering and reduces component count vs. two separate diodes with individual cathode traces. |
| Telecom Power Shelf | Automotive Infotainment PSU |
Use Scenario: +48V input telecom rectifier stage feeding intermediate bus converters in distributed power architecture. IC Role / Device Role / Timing Role: High-current, high-reliability output rectifier handling 10A continuous load with 110A surge tolerance. Use Value: RθJC = 20°C/W allows direct thermal attachment to chassis-mounted heatsink, sustaining operation at 70°C ambient without derating. | Use Scenario: 12V-to-5V/3.3V isolated DC/DC for head unit display and audio subsystems in vehicles with wide ambient range (-40°C to +105°C). IC Role / Device Role / Timing Role: Dual-output rectifier supporting redundant power paths with low leakage (<20 µA @ 125°C) to meet automotive standby current targets. Use Value: Stable VF and IR across -65°C to +175°C junction range ensures consistent regulation and no cold-start failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10120CT-13 | Same die, identical electrical specs, but uses alternate marking code and minor internal trace routing; RθJC = 20°C/W confirmed. | No functional difference; qualified for same industrial and telecom applications per Diodes Inc. documentation. | Select when SBR10120CTL-13 is unavailable; fully interchangeable in layout and thermal design. |
| MBR10120CTG | Standard Schottky with VF ≈ 0.92 V @ 5A/25°C and VRRM = 120V; higher IR (≤1.0 mA @ 125°C) and no soft recovery. | Higher conduction loss and EMI risk in >200 kHz designs; not suitable for high-temperature or low-standby-power systems. | Use only if cost sensitivity outweighs efficiency and thermal requirements; requires revised thermal design. |
Compared with SBRT10120CT-13, SBR10120CTL-13 offers identical performance but distinct traceability; versus MBR10120CTG, it delivers 50 mV lower VF and 10× lower leakage at 125°C-critical for thermally constrained or energy-efficient designs.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR10120CTL-13 is rated for continuous operation from –65°C to +175°C junction temperature. At 175°C, leakage current remains ≤20 µA at 120V reverse bias, and forward voltage drops to 0.74 V at 5A-enabling use in under-hood automotive or high-ambient industrial environments without derating.
Can this device replace a standard Schottky rectifier in an existing design?
Yes, provided the layout accommodates the TO252 package and thermal pad connection. The SBR10120CTL-13 matches the pinout and footprint of standard TO252 dual Schottkys, but delivers lower VF (0.88 V vs. typical 0.92 V) and significantly lower IR at high temperature-yielding measurable efficiency and thermal improvement without circuit modification.
Is the cathode pin electrically connected to the thermal pad?
Yes, pin 2 (cathode) is internally bonded to the exposed thermal pad on the underside of the TO252 package. This provides a low-resistance, low-inductance current return path and enables direct thermal conduction to the PCB copper area, which must be designed as part of the cathode net per the recommended pad layout in DS35588.
Does this part support lead-free reflow soldering?
Yes, the SBR10120CTL-13 features matte tin-plated terminals qualified to MIL-STD-202 Method 208 and compatible with standard lead-free reflow profiles (peak temperature ≤ 260°C). Its UL 94V-0 molding compound and moisture sensitivity level 1 rating eliminate bake requirements prior to assembly.
