Product details
Overview
SBR1045CTL-13 from Diodes Incorporated is a 10A dual-leg Super Barrier Rectifier (SBR®) in TO252 (DPAK) package, rated for 45V peak reverse voltage, 0.55V max forward voltage at 5A/25°C, and 0.5mA max leakage at 45V/25°C - optimized for high-efficiency DC-DC converters and switching power supplies.
For engineers reviewing the SBR1045CTL-13 datasheet, SBR1045CTL-13 pinout, SBR1045CTL-13 application, or SBR1045CTL-13 equivalent, key selection criteria include ultra-low VF stability across temperature, soft-switching behavior for EMI reduction, and TO252 thermal performance with 35°C/W junction-to-ambient resistance under standard mounting.
Technical Context
This dual-leg SBR rectifier uses patented super barrier technology to achieve lower forward voltage than Schottky diodes while maintaining higher reverse voltage capability and superior high-temperature leakage stability. It delivers soft, fast switching with minimal reverse recovery charge, reducing switching losses and system-level EMI.
Rated for 10A average output current at TC = +110°C and 90A non-repetitive surge (8.3ms half-sine), it operates from –65°C to +150°C and features halogen- and antimony-free "Green" construction compliant with RoHS 2 and JEDEC Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IO (per leg) | 5 A - Continuous forward current rating per internal die leg; supports 10A total dual-leg parallel conduction |
| VF (max) | 0.55 V @ 5A, 25°C - Ultra-low forward drop reduces conduction loss by >30% vs. standard FRDs in 12V-output SMPS |
| IR (max) | 0.5 mA @ 45V, 25°C - Low leakage enables stable operation in high-impedance bias networks and standby circuits |
| RθJA | 35 °C/W - Thermal resistance with 2-inch² Al board; enables 10A operation at TC ≤ 110°C without forced cooling |
| IFSM | 90 A - Surge rating allows robust handling of inrush and transient overloads in DC-DC input stages |
| TJ Range | –65°C to +150°C - Wide junction temperature range supports automotive under-hood and industrial ambient conditions |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-die dual-leg configuration with exposed cathode pad for thermal enhancement. Molded green compound, UL 94V-0 rated, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | Anode of first rectifier leg | Connects to switching node (e.g., MOSFET drain) in synchronous or freewheeling path |
| 2 (Cathode) | Common cathode terminal | Shared output node; soldered to large PCB copper pour for thermal dissipation and low-inductance return |
| 3 (Anode B) | Anode of second rectifier leg | Enables dual-phase or interleaved converter topologies with independent anode routing |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.55 V max @ 5A/25°C - cuts conduction loss by ~40% vs. 0.9V FRD in 48V→12V buck converters |
| Soft switching | Negligible reverse recovery charge (Qrr) - eliminates voltage spikes and snubber requirements in hard-switched topologies |
| High-temp IR stability | 13 mA max leakage @ 45V/125°C - maintains regulation integrity in hot environments without derating |
| RoHS & Green compliance | Halogen-free (<900 ppm Br/Cl), antimony-free (<1000 ppm), lead-free - meets IPC-1752A Tier 1 reporting and EU SCIP requirements |
Applications

IC Role / Device Role / Timing Role: Input protection and freewheeling diode in 12V/24V step-down regulators feeding SoCs. Use Value: –65°C to +150°C operating range and low IR at high temp ensure reliability in under-hood thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1045CT-13 | Same electrical specs; TO263 (D2PAK) package with higher RθJA (25°C/W) and larger footprint | Better thermal margin at high ambient but requires more PCB area; not drop-in compatible | Select when board space permits and junction temperature must stay <125°C at 10A continuous |
| MBR1045CT | Standard Schottky; VF = 0.75V max @ 5A, IR = 10mA @ 45V/125°C, lower VRRM margin | Higher conduction loss and thermal drift; unsuitable for high-temp or high-efficiency designs | Only consider if cost is primary constraint and thermal derating can be accommodated |
Compared with SBRT1045CT-13, SBR1045CTL-13 offers identical performance in a smaller TO252 footprint ideal for space-constrained boards; versus MBR1045CT, it delivers 27% lower VF and 75× less high-temp leakage - critical for thermally demanding 5G and automotive applications.

FAQ
What is the maximum continuous current rating for SBR1045CTL-13?
The device is rated for 10A average rectified output current at case temperature TC = +110°C, with each internal leg supporting 5A. At TC = +25°C, derating curves allow up to ~6.5A average per leg before exceeding thermal limits on a standard 2-inch² aluminum board.
Is SBR1045CTL-13 pin-compatible with standard TO252 dual-diode packages?
Yes - it uses standard TO252 (DPAK) pinout: Pin 1 = Anode A, Pin 2 = Common Cathode, Pin 3 = Anode B. This matches industry-standard dual-anode configurations used in MBR10xxCT and SBRT10xxCT series, enabling direct PCB layout reuse.
How does SBR1045CTL-13 improve EMI performance compared to conventional rectifiers?
Its patented super barrier structure provides soft, quasi-zero reverse recovery with negligible Qrr, eliminating high-frequency ringing during turn-off. This reduces conducted and radiated emissions, often allowing removal of snubbers and simplifying filter design in Class B EMI-sensitive applications like telecom and medical power supplies.
Does SBR1045CTL-13 require special PCB layout considerations for thermal management?
Yes - the exposed cathode pad (Pin 2) must be connected to a minimum 2-inch² copper area using multiple thermal vias to inner ground planes. Diodes Inc. AP02001 pad layout is recommended; insufficient copper area raises RθJA above 35°C/W, risking thermal runaway at full 10A load.
