Product details
Overview
SBR3045SCTB-13-G from Diodes Incorporated is a 45 V, 30 A total (15 A per leg) Super Barrier Rectifier in TO263AB (D2PAK) package, featuring 0.65 V max forward voltage at 15 A and 0.2 mA max reverse leakage at 45 V/25°C. It serves as a high-efficiency rectifier, freewheel diode, or blocking diode in DC-DC converters and AC-DC adapters, with patented SBR® technology enabling soft, fast switching and +200°C maximum junction temperature rating.
For engineers reviewing the SBR3045SCTB-13-G datasheet, SBR3045SCTB-13-G pinout, SBR3045SCTB-13-G application, or SBR3045SCTB-13-G equivalent, key selection criteria include its dual-leg 15 A per leg current rating, 2 °C/W typical junction-to-case thermal resistance, +175°C continuous operating junction temperature, and suitability for solar bypass diode use under high-temperature, high-reliability conditions.
Technical Context
This dual-anode, common-cathode Super Barrier Rectifier integrates two independent 15 A rectifying elements in a single TO263AB package, sharing one cathode terminal and two anode terminals. Its patented SBR® structure delivers lower forward voltage than Schottky diodes while maintaining superior reverse leakage performance versus standard PN junction rectifiers.
The device is rated for 220 A non-repetitive peak surge current (8.3 ms half-sine), supports 45 V peak repetitive reverse voltage per leg, and exhibits thermal derating down to zero average forward current at +175°C case temperature - enabled by its 2 °C/W RθJC and selective +200°C junction rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum peak repetitive reverse voltage per leg; defines safe blocking capability in 48 V nominal systems. |
| IO (per leg) | 15 A - Continuous average forward current per anode leg; enables 30 A total output when both legs used in parallel configuration. |
| VF (max) | 0.65 V @ 15 A, 25°C - Low conduction loss improves efficiency in high-current DC-DC and adapter secondary-side rectification. |
| IR (max) | 0.2 mA @ 45 V, 25°C - Ultra-low leakage preserves system standby power and enables reliable solar panel bypass operation. |
| RθJC | 2 °C/W - Enables direct heatsink mounting for high-power dissipation; supports >20 W continuous power handling with modest thermal interface. |
| TJ (max) | +200°C - Selectively rated junction temperature allows sustained operation in thermally constrained enclosures or under elevated ambient conditions. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, 3-terminal molded plastic package with exposed copper drain pad for thermal and electrical connection. Lead-free, RoHS-compliant, halogen- and antimony-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first rectifying element | Accepts AC or pulsating DC input; electrically isolated from Anode 2 but shares cathode path. |
| Anode 2 (A2) | Input terminal for second rectifying element | Enables dual-channel or parallel rectification; identical electrical characteristics to A1. |
| Cathode (K) | Common output terminal for both legs | Single low-impedance return path; connects to PCB thermal pad for heat dissipation and circuit ground/reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-leg 15 A per anode architecture | Supports redundant or parallel rectification paths without external paralleling components; reduces layout complexity in high-current outputs. |
| Patented SBR® technology | Combines Schottky-like VF with PN-junction-level IR - achieves 0.65 V/15 A and 0.2 mA/45 V simultaneously. |
| +200°C maximum junction rating | Validated for extended thermal margin in automotive under-hood, industrial motor drives, and solar string applications. |
| Soft, fast switching behavior | Minimizes EMI generation and voltage overshoot during turn-off - critical for high-frequency DC-DC converter secondary side. |
Applications
| Solar Panel Bypass Diode | High-Efficiency DC-DC Converter Output Rectifier |
|---|---|
Use Scenario: Installed across individual PV cell substrings to prevent hot-spot damage during partial shading or cell failure. IC Role / Device Role / Timing Role: Blocking diode that conducts only during reverse bias fault condition; must sustain 45 V blocking and dissipate minimal power in normal operation. Use Value: 0.2 mA max IR at 25°C and +200°C rating ensure long-term reliability and low thermal runaway risk in unventilated rooftop arrays. | Use Scenario: Secondary-side synchronous rectifier replacement in 12 V–24 V output, 100–500 kHz isolated DC-DC converters for telecom and server power supplies. IC Role / Device Role / Timing Role: Uncontrolled rectifier providing low-VF, low-loss DC conversion; operates at switching frequency harmonics with soft recovery. Use Value: 0.65 V VF at 15 A reduces conduction loss by ~30% vs. standard FRDs, improving full-load efficiency by up to 1.2%. |
| AC-DC Adapter Secondary Rectifier | Industrial Motor Drive Freewheel Diode |
Use Scenario: Output rectification in compact wall-plug adapters delivering 12–24 V at ≥20 W, where thermal density and no-load power are critical. IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier converting transformer secondary AC to regulated DC; handles repetitive 60 Hz or high-frequency ripple. Use Value: TO263AB package with 2 °C/W RθJC enables direct heatsinking on small PCB areas, eliminating need for discrete heatsinks in space-constrained designs. | Use Scenario: Freewheel path for inductive loads in 24–48 V DC motor control modules, especially in sealed enclosures with limited airflow. IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback energy during MOSFET turn-off; must handle high di/dt and 220 A surge peaks. Use Value: 220 A IFSM rating and soft recovery minimize voltage spikes and EMI, protecting gate drivers and reducing snubber component count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT3045CTB-13-G | Same 45 V/30 A rating, but uses trench Schottky architecture; VF = 0.59 V (typ) at 15 A, IR = 0.5 mA (max) at 45 V/25°C. | Higher leakage limits use in ultra-low-power standby circuits; slightly better efficiency at light load. | Prefer when lowest possible VF dominates over leakage; verify thermal design for higher IR-induced self-heating. |
| MBR3045CT-13 | Standard dual Schottky rectifier; VF = 0.72 V (max) at 15 A, IR = 1.0 mA (max) at 45 V/25°C, RθJC = 2.5 °C/W. | Lower cost but reduced thermal margin and higher conduction/leakage losses; not rated for +200°C operation. | Select for cost-sensitive, non-automotive, <+150°C ambient applications where 0.07 V higher VF is acceptable. |
Compared with SBRT3045CTB-13-G and MBR3045CT-13, the SBR3045SCTB-13-G uniquely balances ultra-low VF, ultra-low IR, and +200°C junction rating - making it optimal for solar bypass and thermally aggressive industrial rectification where long-term reliability outweighs marginal cost differences.

FAQ
What is the thermal pad connection requirement for SBR3045SCTB-13-G?
The exposed copper pad on the TO263AB package is electrically connected to the cathode (K) terminal and must be soldered to a large PCB copper area or heatsink. Minimum recommended pad size is 10.41 mm × 7.01 mm per datasheet layout guidelines; thermal via count and copper thickness directly impact achievable RθJA.
Can SBR3045SCTB-13-G be used in parallel configurations?
Yes - its dual-anode, common-cathode topology supports internal parallel operation of both legs. External parallel use with other SBR3045SCTB-13-G units requires matched VF and thermal mounting to ensure current sharing; external ballast resistors are not recommended due to efficiency loss.
Is SBR3045SCTB-13-G qualified for automotive applications?
No - this part is not AEC-Q101 qualified. While it features +200°C junction rating and robust construction, Diodes specifies that automotive-grade versions require explicit AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing - contact Diodes directly for qualified alternatives like the SBR3045SCTBQ-13-G.
How does the SBR® technology differ from standard Schottky rectifiers?
SBR® uses a proprietary barrier engineering process that modifies the metal-semiconductor interface to suppress thermionic emission leakage while retaining low forward voltage. This yields VF comparable to Schottky devices (e.g., 0.65 V) but IR values closer to PN rectifiers (e.g., 0.2 mA vs. >1 mA for typical Schottkys at same voltage/current).
