Product details
Overview
SBR40100CTFP-G from Diodes Incorporated is a 100 V, 40 A dual common-cathode Super Barrier Rectifier in ITO-220AB package, designed for high-efficiency AC/DC and DC/DC power conversion where low forward voltage (0.73 V @ 20 A, 125°C) and soft switching reduce conduction loss and EMI. It serves as the output rectifier in server PSUs, telecom power supplies, and industrial SMPS.
For engineers reviewing the SBR40100CTFP-G datasheet, SBR40100CTFP-G pinout, SBR40100CTFP-G application, or SBR40100CTFP-G equivalent, key selection criteria include peak repetitive reverse voltage (100 V), average forward current per leg (20 A), thermal resistance (4°C/W), junction temperature range (–65°C to +175°C), and RoHS-compliant green packaging.
Technical Context
This dual-diode rectifier integrates two independent SBR (Super Barrier Rectifier) elements sharing a common cathode terminal, enabling synchronous-like efficiency without gate drive complexity. Its patented barrier structure delivers lower VF than Schottky diodes at high temperature while maintaining superior leakage control versus standard PN junctions.
The device operates across –65°C to +175°C junction temperature, with thermal resistance of 4°C/W (junction-to-case, ITO-220AB), supporting high-power density designs when mounted on heatsinks. Soft, fast switching minimizes reverse recovery ringing and associated EMI in high-frequency switching topologies like LLC resonant converters.
Key Specifications

| IO (per leg) | 20 A - Continuous average forward current per diode element; total device rating is 40 A with shared cathode configuration. |
| VF @ 20A, 125°C | 0.73 V - Low conduction loss at elevated temperature ensures stable efficiency in thermally constrained environments. |
| IR @ 100V, 125°C | 10 µA - Ultra-low high-temperature leakage preserves system standby power and prevents thermal runaway. |

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 |
|---|---|---|---|
| SBRT40100CTFP-G | Same ITO-220AB package, identical electrical specs, but uses enhanced thermal pad construction for improved RθJC (3.8°C/W typical). | Better suited for ultra-dense 1U server PSU designs requiring sub-4°C/W thermal performance. | Select if thermal margin is critical and layout allows same footprint. |
| MBR40100CTFP-G | Standard Schottky version: higher VF (0.85 V @ 20A, 125°C), higher IR (50 µA @ 125°C), no soft-switching benefit. | Acceptable where cost is prioritized over efficiency and EMI, e.g., non-EMI-sensitive industrial controls. | Choose only if efficiency >94% and Class B EMC are not required. |
Compared with SBRT40100CTFP-G, SBR40100CTFP-G offers proven thermal reliability at standard cost; versus MBR40100CTFP-G, it delivers measurable efficiency gain and EMI reduction in high-frequency, high-density power designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The ITO-220AB package supports continuous operation up to +175°C junction temperature. With RθJC = 4°C/W, sustained case temperatures must remain ≤165°C when dissipating 2.5 W (e.g., 20 A × 0.125 V drop) to maintain safe margin. Derating curves in Figure 3 confirm 20 A rating at TC = 100°C.
Can SBR40100CTFP-G replace a standard TO-220AB dual diode in existing layouts?
No - ITO-220AB has different mechanical dimensions and isolated tab. While pinout matches (A-K-A), the tab is electrically isolated and requires verification of creepage/clearance distances. Mounting hole centers differ (E = 10.11 mm vs. TO-220AB's 10.66 mm), so PCB redesign is necessary for mechanical fit and isolation compliance.
Is the "-G" suffix solely for green compound, or does it affect electrical performance?
The "-G" suffix indicates halogen- and antimony-free molding compound per Diodes' definition (<900 ppm Br/Cl, <1000 ppm Sb). Electrical specifications, thermal performance, and reliability testing are identical to non-G versions; only material composition differs to meet environmental mandates.
How does soft switching manifest in circuit behavior?
Soft switching eliminates abrupt reverse recovery current spikes, resulting in slower di/dt during turn-off. This reduces high-frequency ringing on drain-source nodes, lowers radiated emissions above 30 MHz, and decreases stress on MOSFETs in synchronous rectified topologies - verified by oscilloscope waveforms in Diodes' application note AN-4001.
