Product details
Overview
SBR40U200CTB-13 from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 200V peak repetitive reverse voltage, with typical forward voltage of 0.85V at 20A/25°C and 0.75V at 20A/125°C, used in high-efficiency AC/DC and DC/DC power supplies for telecom and industrial equipment.
For engineers reviewing the SBR40U200CTB-13 datasheet, SBR40U200CTB-13 pinout, SBR40U200CTB-13 application, or SBR40U200CTB-13 equivalent, key selection criteria include forward voltage drop at elevated temperature, soft-switching recovery behavior, thermal resistance (RθJC = 2°C/W), leakage current at 125°C, and TO263AB mounting compatibility with high-current PCB layouts.
Technical Context
This device implements patented Super Barrier Rectifier (SBR®) technology to achieve ultra-low VF while maintaining low IR and soft reverse recovery-critical for reducing conduction and switching losses in high-frequency SMPS topologies. Its dual common-cathode configuration supports center-tapped transformer rectification or parallel-leg current sharing.
Designed for operation up to +175°C junction temperature, it delivers stable performance under thermal stress with <40mA leakage at VR=200V and TJ=+125°C, and trr of 38ns (typ) under standardized di/dt=100A/µs conditions-enabling efficient operation in PFC stages and synchronous rectifier auxiliary paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IO (TC=100°C) | 40 A - Continuous average forward current per leg at case temperature of 100°C |
| VF (20A, 25°C) | 0.85 V - Forward voltage drop per leg at nominal load, directly impacting conduction loss |
| VF (20A, 125°C) | 0.75 V - Lower VF at high temperature improves efficiency stability in thermally constrained designs |
| trr (typ) | 38 ns - Soft, fast reverse recovery minimizes switching noise and EMI in high-frequency converters |
| IR (200V, 125°C) | 40 mA - Low high-temp leakage preserves efficiency in hot ambient environments |
| RθJC | 2 °C/W - Thermal resistance from junction to case enables direct heatsink mounting for high-power dissipation |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, 3-terminal configuration with exposed copper pad for thermal enhancement and mechanical anchoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage Super Barrier Rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-40CPH02-M3 | 200V VRRM, 40A IO, VF = 0.82V @ 20A/25°C, trr = 45ns, TO247AC package | Higher RθJA, through-hole mounting, less suitable for high-density SMT layouts | Select when board-level thermal management favors through-hole heatsinking over D2PAK footprint |
| ON Semiconductor MUR4020CT | 200V VRRM, 40A IO, VF = 1.05V @ 20A/25°C, trr = 60ns, TO220AB package | Standard ultrafast recovery, higher VF increases conduction loss by ~26% at 20A | Select only if cost sensitivity outweighs efficiency and thermal performance requirements |
Compared with VS-40CPH02-M3 and MUR4020CT, SBR40U200CTB-13 delivers lower VF at high temperature and superior soft-switching behavior in a surface-mount TO263AB package-making it optimal for space-constrained, high-efficiency power supplies where thermal performance and EMI control are critical.

FAQ
What is the maximum junction temperature rating for SBR40U200CTB-13?
The absolute maximum junction temperature is +175°C, with continuous operation specified across –65°C to +175°C. The device maintains stable electrical characteristics-including leakage current and forward voltage-within this range, validated per JEDEC JESD22-A108.
Is SBR40U200CTB-13 pin-compatible with standard TO263AB dual-diode rectifiers?
Yes-it uses the standard TO263AB (D2PAK) 3-pin outline with Anode1–Cathode–Anode2 pin assignment. Mechanical dimensions match JEDEC MO-211DA, and the exposed thermal pad aligns with industry-standard D2PAK land patterns per Diodes AP02001.
How does the SBR® technology differ from conventional Schottky or ultrafast diodes?
SBR® combines a modified Schottky barrier with a lightly doped drift region to achieve lower VF than Schottkys at high current while suppressing leakage and enabling soft recovery-unlike Schottkys (high IR above 125°C) or ultrafast diodes (hard recovery, higher VF).
Can SBR40U200CTB-13 be used in synchronous rectification circuits?
No-it is a passive rectifier and not designed for gate-controlled operation. It serves as a high-efficiency replacement for Schottky or ultrafast diodes in non-synchronous topologies; synchronous rectification requires actively driven MOSFETs with precise timing control.
