Product details
Overview
SBR40U200CTB from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 200V peak repetitive reverse voltage, with ultra-low 0.85V forward voltage at 20A/25°C and 0.93V at 20A/125°C, used in high-efficiency AC-DC front-end rectification for industrial power supplies.
For engineers reviewing the SBR40U200CTB datasheet, SBR40U200CTB pinout, SBR40U200CTB application, or SBR40U200CTB equivalent, key selection criteria include thermal resistance (2°C/W junction-to-case), soft-switching recovery time (38–50ns), low leakage (<0.2mA @200V/25°C), and RoHS-compliant green packaging.
Technical Context
This dual-anode, single-common-cathode rectifier integrates two independent SBR die in one thermally optimized D2PAK package, enabling interleaved or parallel rectification without external current-sharing components. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to reduce forward conduction loss while maintaining fast, soft reverse recovery.
The device operates across –65°C to +175°C with stable leakage performance up to 40mA at 200V/125°C and supports high di/dt switching (100A/µs) without oscillation, making it suitable for high-frequency PFC stages and synchronous rectifier replacement in telecom and server SMPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 200 V - Withstands full bridge or boost converter output voltage spikes without breakdown |
| Avg. Forward Current | 40 A @ TC = +100°C - Supports high-power output stages with minimal heatsink requirement |
| Forward Voltage | 0.85 V @ 20A/25°C - Reduces conduction loss by ~30% vs. standard Schottky at same rating |
| Reverse Recovery Time | 38 ns (typ) @ IF=0.5A, IR=1A - Enables >300 kHz operation with low EMI and reduced snubber losses |
| Junction-to-Case Rθ | 2 °C/W - Allows direct mounting to heatsink for efficient thermal management in compact designs |
| Leakage Current | 0.2 mA @ 200V/25°C - Maintains efficiency in standby mode and high-temperature environments |
| Surge Current | 240 A (8.3ms half-sine) - Survives cold-start inrush and line transients without degradation |
Pinout & Package
TO263AB (D2PAK) surface-mount package with exposed copper drain pad for thermal dissipation; 3-terminal configuration: Anode 1, Cathode (common), Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first rectifier leg | Accepts AC or switched input; electrically isolated from Anode 2 |
| Cathode (Common) | Shared output node for both legs | Provides single DC output path; must be routed with low-inductance, high-current trace |
| Anode 2 | Input terminal for second rectifier leg | Enables dual-phase or center-tapped transformer rectification without external wiring |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.85 V @ 20A/25°C reduces conduction loss by ≥25% vs. comparable 40A Schottky diodes |
| Soft switching | Controlled minority-carrier recombination minimizes voltage overshoot and EMI during turn-off |
| High-temp stability | Leakage remains <40 mA @ 200V/125°C - enables reliable operation in sealed industrial enclosures |
| Green construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A Tier 1 |
| Thermal robustness | Rated for continuous operation up to +175°C junction temperature - extends lifetime in high-ambient designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-40CPH02-M3 | 200V, 40A, VF = 0.82V @ 20A/25°C; higher trr (65ns); TO247AC package | Larger footprint and higher thermal resistance (0.5°C/W vs. 2°C/W) limits high-density layouts | Prefer when mechanical mounting to large heatsinks is prioritized over PCB space |
| ON Semiconductor MUR4020CT | 200V, 40A, VF = 1.1V @ 20A/25°C; faster trr (30ns); standard ultrafast recovery, not SBR | Higher conduction loss increases thermal load; requires larger heatsink in 100°C ambient | Choose only if cost sensitivity outweighs efficiency targets and board area constraints |
Compared with VS-40CPH02-M3 and MUR4020CT, SBR40U200CTB delivers optimal balance of low VF, soft switching, and D2PAK thermal performance-enabling smaller, cooler, and quieter power systems without sacrificing surge robustness.

FAQ
What is the maximum recommended PCB copper area for thermal relief with SBR40U200CTB?
Per Diodes' AP02001 layout guide, use ≥250 mm² of 2 oz. copper on the cathode pad, connected via ≥4 thermal vias (0.3mm diameter, filled) to inner ground/power planes. This achieves the specified 2°C/W RθJC and prevents localized hot spots above 135°C under 40A continuous load.
Can SBR40U200CTB be used in synchronous rectification topologies?
No-SBR40U200CTB is a passive rectifier and lacks gate control. It serves as a high-performance replacement for Schottky diodes in non-synchronous topologies like boost PFC or LLC secondary-side rectification, but cannot substitute for MOSFET-based synchronous rectifiers requiring active drive signals.
Is the "-G" suffix required to meet RoHS 2 compliance?
No-SBR40U200CTB (without -G) is fully RoHS 2 compliant per EU Directive 2011/65/EU. The "-G" suffix denotes halogen- and antimony-free green molding compound, an additional environmental specification beyond RoHS; both versions meet lead-free soldering requirements and MIL-STD-202 solderability standards.
How does SBR40U200CTB's leakage compare to standard Schottky diodes at elevated temperature?
At 125°C and 200V reverse bias, SBR40U200CTB exhibits ≤40mA leakage-comparable to high-barrier Schottkys and significantly lower than conventional Schottkys (>100mA). This stability stems from its super barrier architecture, which suppresses thermionic emission better than metal-silicon junctions.
